長距離分佈地下電纜電路(諸如用於風力農場電力收集系統中之電纜電路)經受在電纜上之電纜金屬屏蔽層中之電荷積累。電荷積累可變得如此大以致電纜歸因於由穿過金屬屏蔽層之接地電流產生之熱而不得不降額(亦即，以次最佳狀態操作)。熱為促成電纜降級之因素。Long-distance distribution of underground cable circuits, such as cable circuits used in wind farm power collection systems, is subject to charge build-up in the cable metal shield on the cable. The charge buildup can become so large that the cable has to be derated (i.e., operated in a suboptimal state) due to the heat generated by the ground current through the metal shield. Heat contributes to the degradation of the cable.

To form the cable assembly 20, each of the cable insulation 28, the cable insulation shield 30, the cable metal ground 32, and the cable jacket 34 is stripped rearwardly from one end of the cable 24 to expose one of the underlying layers until the cable conductor 26. The cable connector 22 is then attached to the exposed portion of the cable conductor 26 by any suitable means, typically by crimping. In the embodiment of FIG. 1, the cable metal ground plane 32 includes metal wires that are folded back, gathered, and attached to the small connector, which in turn is attached to the outer conductor 38 (separate cable). In the embodiment of FIG. 1, an insulating bushing 36 is applied to the cable assembly 20 to cause the cable insulation shield 30 and the cable metal ground 32 and the external semiconductor of the connection device 100 when the cable assembly 20 is inserted into the connector 100.

Any suitable means for electrically insulating the cable assembly 20 from the semiconductive layer of the connector 100 can be used in place of the insulating bushing 36.
本發明之連接裝置可為適合在前端封閉端子中使用，可容納具有隔離屏蔽之電纜總成且適於進行如本文描述之交叉互連之任何連接器。圖2展示連接裝置100，其包括大體上界定第一腔室104及第二腔室106之外殼102。第一腔室104與第二腔室106相交，使得第一腔室104之內部與第二腔室106之內部連通。第一腔室104及第二腔室106可相交以形成如圖2中展示之大體T形或大體L形(未圖示)。外殼102進一步包括外部半導電層110、中間絕緣層112及內部半導電層114。此等層中之每一者之一部分部分地形成第一腔室104之內部壁。The connector of the present invention can be any connector suitable for use in a front end closed terminal that can accommodate a cable assembly having an isolated shield and that is suitable for cross-connecting as described herein. 2 shows a connection device 100 that includes a housing 102 that generally defines a first chamber 104 and a second chamber 106. The first chamber 104 intersects the second chamber 106 such that the interior of the first chamber 104 is in communication with the interior of the second chamber 106. The first chamber 104 and the second chamber 106 may intersect to form a generally T-shape or a generally L-shape (not shown) as shown in FIG. The outer casing 102 further includes an outer semiconductive layer 110, an intermediate insulating layer 112, and an inner semiconductive layer 114. One of each of these layers partially forms an inner wall of the first chamber 104.
外殼102可由適於冷收縮應用之任何材料製成。大多數合適的材料為具有低永久變形之諸如高彈性橡膠材料之材料，諸如乙烯丙烯二烯單體(EPDM)、彈性體聚矽氧或其混合物。半導電及絕緣材料可由相同或不同類型之材料製成。基於所使用材料之固有性質或基於添加至材料之添加劑，半導電及絕緣材料可具有不同程度之導電性及絕緣性。The outer casing 102 can be made of any material suitable for cold shrink applications. Most suitable materials are materials such as highly elastic rubber materials having low permanent deformation, such as ethylene propylene diene monomer (EPDM), elastomeric polyoxane or mixtures thereof. Semiconductive and insulating materials can be made of the same or different types of materials. Based on the inherent properties of the materials used or based on the addition of materialsAgents, semiconducting and insulating materials can have varying degrees of electrical conductivity and insulation.
為了使電纜總成20能夠插入至連接裝置100之第一腔室104中，可首先將可移除支撐核心200裝載至第一腔室104中，如圖3中說明。一旦經裝載，可移除支撐核心200通常自第一腔室104之上部部分之最接近第二腔室106的末端延伸超出第一腔室104之開口末端109，電纜總成20經由該開口末端109插入。當裝載至第一腔室104中時，可移除支撐核心200將第一腔室104徑向擴大至一內徑，該內徑大於將被插入至第一腔室104中之電纜總成20之最大部分之外徑。To enable the cable assembly 20 to be inserted into the first chamber 104 of the connection device 100, the removable support core 200 can first be loaded into the first chamber 104, as illustrated in FIG. Once loaded, the removable support core 200 generally extends from the end of the upper portion of the first chamber 104 that is closest to the second chamber 106 beyond the open end 109 of the first chamber 104 via which the cable assembly 20 is terminated. 109 inserts. When loaded into the first chamber 104, the removable support core 200 radially expands the first chamber 104 to an inner diameter that is greater than the cable assembly 20 to be inserted into the first chamber 104 The outer diameter of the largest part.
可移除支撐核心200可由任何合適材料且以任何合適組態製造，但通常由螺旋纏繞之擠製耐綸或丙烯帶組成。可藉由拆散可移除支撐核心200而將其自第一腔室104移除。藉由拉動自可移除支撐核心200之一個末端延伸之凸片(未圖示)且使該核心沿著螺旋劃痕線或接合點分離而拆散可移除支撐核心200。較佳地，以從第一腔室104之上部部分中的最接近第二腔室106的末端開始且結束於延伸超出第一腔室104之開口末端109的末端的方式拆散可移除支撐核心200。以此方式拆散可移除支撐核心200防止第一腔室104之開口末端109過早塌縮並妨礙可移除支撐核心200之移除。The removable support core 200 can be made of any suitable material and in any suitable configuration, but typically consists of a spiral wound extruded nylon or propylene tape. The removable support core 200 can be removed from the first chamber 104 by disassembling it. The removable support core 200 is disassembled by pulling a tab (not shown) extending from one end of the removable support core 200 and separating the core along a spiral score line or joint. Preferably, the removable support core is disassembled from the end of the upper portion of the first chamber 104 that is closest to the end of the second chamber 106 and ends at an end that extends beyond the open end 109 of the first chamber 104. 200. Disassembling the removable support core 200 in this manner prevents the open end 109 of the first chamber 104 from collapsing prematurely and hinders removal of the removable support core 200.
一旦已將可移除支撐核心裝載至第一腔室104中，便可將電纜總成20插入至第一腔室104中。通常，電纜連接器22將在其自由末端處包括孔隙23。自由末端定位於第一腔室104與第二腔室106之相交處中，同時電纜連接器之剩餘部分駐留於第一腔室104中。一旦電纜總成經正確定位，便插入配合裝置且將電纜固持於適當位置。接著可如上文所述移除可移除支撐核心200以使第一腔室104緊縮且在電纜總成20周圍形成緊密密封。Once the removable support core has been loaded into the first chamber 104, the cable assembly 20 can be inserted into the first chamber 104. Usually, cable connector22 will include an aperture 23 at its free end. The free end is positioned in the intersection of the first chamber 104 and the second chamber 106 while the remainder of the cable connector resides in the first chamber 104. Once the cable assembly is properly positioned, the mating device is inserted and the cable is held in place. The removable support core 200 can then be removed as described above to tighten the first chamber 104 and form a tight seal around the cable assembly 20.
在圖4A之實施例中，當組裝前端封閉端子時，內部半導電層114之包含外殼102之第一腔室104之內部壁的部分與電纜總成20之電纜連接器22密切接觸。第一腔室104之內部壁之第二部分包含中間絕緣層112，且第一腔室104之內部壁之第三部分包含外部半導電層110。為了實現屏蔽隔離及交叉互連，防止內部壁之第三部分與電纜絕緣屏蔽30及與電纜金屬接地層32電接觸。在圖4A之實施例中，藉由絕緣襯套36而防止此電接觸。第一腔室104之內部壁的包含外部半導電層110之部分較佳與絕緣襯套36之部分密切接觸以防止污染物及/或濕氣進入第一腔室104中。外部導體38電連接至電纜金屬接地層32，因此電纜金屬接地層32可交叉互連至第二前端封閉端子中的另一電纜之電纜金屬接地層32。In the embodiment of FIG. 4A, the portion of the inner semiconducting layer 114 that includes the inner wall of the first chamber 104 of the outer casing 102 is in intimate contact with the cable connector 22 of the cable assembly 20 when the front end closed terminal is assembled. The second portion of the inner wall of the first chamber 104 includes an intermediate insulating layer 112, and the third portion of the inner wall of the first chamber 104 includes the outer semiconductive layer 110. In order to achieve shielding isolation and cross interconnection, the third portion of the inner wall is prevented from being in electrical contact with the cable insulation shield 30 and the cable metal ground plane 32. In the embodiment of FIG. 4A, this electrical contact is prevented by insulating bushing 36. The portion of the inner wall of the first chamber 104 that includes the outer semiconducting layer 110 is preferably in intimate contact with portions of the insulating bushing 36 to prevent contaminants and/or moisture from entering the first chamber 104. The outer conductor 38 is electrically connected to the cable metal ground plane 32 such that the cable metal ground plane 32 can be cross-connected to the cable metal ground plane 32 of the other of the second front end closed terminals.
為了產生圖4A之裝置，首先移除電纜24之諸層(大體上如圖1(及圖4A)中展示)，使得每一層之一部分經曝露。電纜金屬接地層32之導線被拉回且藉由(例如)壓接連接器(crimp connector)連接至外部導體38。接著將絕緣襯套36置放於電纜之曝露部分上(除了電纜導體層26之外)。在此實施例中，絕緣襯套36自電纜絕緣物28之鄰近導體26的末端一直延伸至電纜護套34。其覆蓋電纜護套、金屬接地層32及電纜屏蔽30之一部分以使電纜屏蔽30及電纜金屬接地32與連接裝置100之外部半導電層110絕緣。To create the device of Figure 4A, the layers of cable 24 are first removed (generally as shown in Figure 1 (and Figure 4A)) such that one portion of each layer is exposed. The wires of the cable metal ground plane 32 are pulled back and connected to the outer conductor 38 by, for example, a crimp connector. The insulating bushing 36 is then placed over the exposed portion of the cable (except for the cable conductor layer 26). hereIn an embodiment, the insulating bushing 36 extends from the end of the cable insulator 28 adjacent the conductor 26 to the cable jacket 34. It covers a portion of the cable jacket, metal ground plane 32, and cable shield 30 to insulate the cable shield 30 and the cable metal ground 32 from the outer semiconducting layer 110 of the connector 100.
圖4B展示本發明之前端封閉端子之替代實施例。在圖4B之實施例中，當組裝前端封閉端子時，藉由外部半導電層110形成之第一腔室104之開口末端109鄰近電纜24之電纜絕緣屏蔽30而定位。絕緣襯套36經組態以延伸超出第一腔室104之開口末端109，使得絕緣襯套36比半導電層110覆蓋更多的電纜絕緣屏蔽層30，但絕緣襯套36經組態以使得其不覆蓋電纜金屬接地層32或電纜護套34。電纜金屬接地層32隨後可由保護層覆蓋(諸如膠帶或彈性體襯套)，以防止與污染物及/或濕氣接觸。Figure 4B shows an alternate embodiment of the front end closed terminal of the present invention. In the embodiment of FIG. 4B, the open end 109 of the first chamber 104 formed by the outer semiconducting layer 110 is positioned adjacent the cable insulation shield 30 of the cable 24 when the front end closed terminal is assembled. The insulating bushing 36 is configured to extend beyond the open end 109 of the first chamber 104 such that the insulating bushing 36 covers more of the cable insulation shield 30 than the semiconductive layer 110, but the insulating bushing 36 is configured such that It does not cover the cable metal ground plane 32 or the cable jacket 34. The cable metal ground plane 32 can then be covered by a protective layer (such as a tape or elastomeric bushing) to prevent contact with contaminants and/or moisture.
圖4C展示本發明之前端封閉端子之另一替代實施例。圖4C之實施例類似於圖4A之實施例，不同之處在於絕緣襯套36未自電纜絕緣層28之頂部延伸至電纜護套34之一部分並在其上延伸。替代地，其自電纜絕緣層28之中間部分延伸至電纜護套34之一部分且在其上延伸。Figure 4C shows another alternative embodiment of the front end closed terminal of the present invention. The embodiment of Figure 4C is similar to the embodiment of Figure 4A, except that the insulating bushing 36 does not extend from the top of the cable insulation layer 28 to a portion of the cable jacket 34 and extends over it. Alternatively, it extends from a middle portion of the cable insulation layer 28 to a portion of the cable jacket 34 and extends over it.
如自圖4A至圖4C之實施例可見，電纜絕緣屏蔽30及電纜金屬接地32藉以與第一腔室104之包含外部半導電層110的部分電絕緣的構件可為以下任何合適構件，諸如：膠帶、膏膠(mastic)、剛性管、可壓扁管、可撓性管、實體距離等。電纜絕緣屏蔽30及電纜金屬接地32可藉由相同或不同絕緣構件來絕緣，該等構件可包含一或多個部分或區段。可使用絕緣構件之任何合適組合，只要電纜絕緣屏蔽30及電纜金屬接地層32均與外部半導電層110充分電絕緣即可。As can be seen from the embodiment of FIGS. 4A-4C, the cable insulation shield 30 and the cable metal ground 32 can be electrically insulated from the portion of the first chamber 104 that includes the outer semiconductive layer 110, such as: Tape, mastic, rigid tube, flattenable tube, flexible tube, physical distance, etc. The cable insulation shield 30 and the cable metal ground 32 may be insulated by the same or different insulating members, which may include one or more sections or zonessegment. Any suitable combination of insulating members can be used as long as both the cable insulation shield 30 and the cable metal ground plane 32 are sufficiently electrically insulated from the outer semiconducting layer 110.
圖5至圖8展示一較詳細程序，藉由該程序製備本發明之前端封閉端子以用於交叉互連。圖5展示安裝於電纜總成20上之連接裝置100，電纜總成20具有一可選膏膠環120以在一旦應用可選環境密封管(圖7)時便產生環境密封。圖6展示外部電纜38由可選膠帶層37覆蓋，且接地導線122藉由膠帶39附接至連接裝置100之外部半導電層110。圖7展示可選環境密封管124之應用，該可選環境密封管124在此狀況下為冷收縮管。可選環境密封管124覆蓋連接裝置100之一部分、絕緣襯套36之先前曝露部分、外部連接器38之部分及電纜護套34之部分。圖8展示完全製備好的端子。外部導體38自環境密封管124之下部末端延伸，且接地導線122自環境密封管124之上部末端(最接近電纜連接器22)延伸。Figures 5 through 8 show a more detailed procedure by which the front end closure terminals of the present invention are prepared for cross-connecting. Figure 5 shows the attachment device 100 mounted on a cable assembly 20 having an optional glue ring 120 to create an environmental seal once the optional environmental seal tube (Figure 7) is applied. 6 shows that the outer cable 38 is covered by an optional tape layer 37, and the ground wire 122 is attached to the outer semiconductive layer 110 of the connector 100 by a tape 39. Figure 7 shows an application of an optional environmental seal tube 124, which in this case is a cold shrink tube. The optional environmental seal tube 124 covers a portion of the connection device 100, a previously exposed portion of the insulating bushing 36, a portion of the outer connector 38, and a portion of the cable jacket 34. Figure 8 shows a fully prepared terminal. The outer conductor 38 extends from the lower end of the environmental seal tube 124 and the ground lead 122 extends from the upper end of the environmental seal tube 124 (closest to the cable connector 22).
在本發明之前，僅已知接頭之交叉互連。通常，接頭交叉互連係藉由具有在不同電壓相位中之電纜金屬接地層的三個相等長度之電纜區段來進行，其中電纜區段在一或多個點處由接頭連接器中斷。當藉由接頭進行交叉互連時，其通常由使進入一個接頭連接器中之電纜的金屬接地層連接至退出不同接頭連接器之電纜的金屬接地層組成，其中該等金屬接地層處於不同電壓相位中。此更詳細說明於圖9中，其中電纜A之第一區段(在每一接頭之左邊)上的金屬接地層連接至電纜B之第二區段(在每一接頭之右邊)上的金屬接地層；電纜B之第一區段上的電纜金屬接地層連接至電纜C之第二區段上的電纜金屬接地層；以及電纜C之第一區段上之電纜金屬接地層連接至電纜A之第二區段上的電纜金屬接地層。Prior to the present invention, only cross-connections of joints were known. Typically, the connector crossover interconnect is performed by three equal length cable sections having a cable metal ground plane in different voltage phases, wherein the cable section is interrupted by the header connector at one or more points. When cross-connected by a joint, it typically consists of a metal ground plane that connects the metal grounding layer of the cable entering a header connector to a cable exiting a different header connector, wherein the metal ground planes are at different voltages In the phase. This is described in more detail in Figure 9, where the metal of the first section of cable A (on the left side of each joint)The ground plane is connected to the metal ground plane on the second section of cable B (on the right side of each joint); the cable metal ground plane on the first section of cable B is connected to the cable on the second section of cable C A metal ground plane; and a cable metal ground plane on the first section of cable C is connected to the cable metal ground plane on the second section of cable A.
圖9說明兩組交叉互連之接頭，其沿著整個電纜長度安裝以便產生三段相等的較小長度之電纜，該等電纜是沿著整個電纜長度完成電纜金屬接地層中之接地電流的相移消除所需的。此等兩組接頭經安裝以產生3段相等長度之電纜，使得在每一區段中產生之接地電流之量值相等，從而在交叉互連電纜之金屬接地層時允許相位消除。Figure 9 illustrates two sets of cross-connected joints that are installed along the entire cable length to produce three equal lengths of smaller length cables that complete the ground current phase in the cable metal ground plane along the entire length of the cable. Remove the required ones. The two sets of joints are mounted to produce three lengths of equal length cables such that the magnitude of the ground current generated in each section is equal, thereby allowing phase cancellation when crossing the metal ground plane of the interconnected cable.
替代電纜接頭連接器，本發明係關於交叉互連前端封閉電纜端子。舉例而言，如圖10所示，提供電纜之九個區段1A、1B、1C、2A、2B、2C、3A、3B及3C。每一電纜區段在兩端由一連接裝置端接。舉例而言，電纜1A藉由連接裝置100A及100A'端接，電纜2A藉由連接裝置200A及200A'端接。在第一接線盒處，在一端藉由連接裝置100A'端接之電纜1A之電纜金屬接地層連接至電纜2B的電纜金屬接地層，電纜2B在一端藉由連接裝置200B端接；在一端藉由連接裝置100B'端接之電纜1B之電纜金屬接地層連接至電纜2C的電纜金屬接地層，電纜2C在一端藉由連接裝置200C端接；以及在一端藉由連接裝置100C'端接之電纜1C之電纜金屬接地層連接至電纜2A之電纜金屬接地層，電纜2A在一端藉由連接裝置200A端接。類似地，在第二接線盒處，在一端藉由連接裝置200A'端接之電纜2A之電纜金屬接地層連接至電纜3B的電纜金屬接地層，電纜3B在一端藉由連接裝置300B端接；在一端藉由連接裝置200B'端接之電纜2B之電纜金屬接地層連接至電纜3C的電纜金屬接地層，電纜3C在一端藉由連接裝置300C端接；以及在一端藉由連接裝置200C'端接之電纜2C之電纜金屬接地層連接至電纜3A之電纜金屬接地層，電纜3A在一端藉由連接裝置300A端接。Instead of a cable splice connector, the present invention relates to a cross-connected front end closed cable terminal. For example, as shown in Figure 10, nine segments 1A, 1B, 1C, 2A, 2B, 2C, 3A, 3B, and 3C of the cable are provided. Each cable section is terminated at both ends by a connecting device. For example, the cable 1A is terminated by the connection devices 100A and 100A', and the cable 2A is terminated by the connection devices 200A and 200A'. At the first junction box, the cable metal ground plane of the cable 1A terminated at one end by the connection device 100A' is connected to the cable metal ground layer of the cable 2B, and the cable 2B is terminated at one end by the connection device 200B; The cable metal ground plane of the cable 1B terminated by the connection device 100B' is connected to the cable metal ground layer of the cable 2C, the cable 2C is terminated at one end by the connection device 200C; and the cable terminated at one end by the connection device 100C' The cable metal ground plane of 1C is connected to the cable metal ground plane of cable 2A, and cable 2A is terminated at one end by connection device 200A. Similarly, inAt the second junction box, the cable metal ground layer of the cable 2A terminated at one end by the connecting device 200A' is connected to the cable metal ground layer of the cable 3B, and the cable 3B is terminated at one end by the connecting device 300B; The cable metal ground plane of the cable 2B terminated by the connecting device 200B' is connected to the cable metal ground layer of the cable 3C, the cable 3C is terminated at one end by the connecting device 300C; and the cable 2C terminated at one end by the connecting device 200C' The cable metal ground plane is connected to the cable metal ground plane of the cable 3A, and the cable 3A is terminated at one end by the connection device 300A.
如同接頭一樣，當交叉互連前端封閉端子時，較佳具有沿著整個電纜長度安裝的兩組交叉互連之端子，以便產生沿著整個電纜長度完成電纜金屬接地層中之接地電流的相移消除所需的三段相等的較小長度之電纜。此等兩組端子經安裝以產生3段相等長度之電纜，使得在每一區段中產生之接地電流之量值相等，從而在交叉互連電纜之金屬接地層時允許相位消除。As with the connector, when the cross-connect front end closes the terminal, it is preferred to have two sets of cross-connected terminals mounted along the entire length of the cable to produce a phase shift of the ground current in the cable metal ground plane along the entire length of the cable. Eliminate the required three equal lengths of cable of smaller length. The two sets of terminals are mounted to produce three lengths of equal length cables such that the magnitude of the ground current generated in each section is equal, thereby allowing phase cancellation when crossing the metal ground plane of the interconnecting cable.
在本發明之前，在諸如風力農場之應用中(該等應用需要通常大於1,000呎之長距離分佈電纜電路)，在電纜中產生接頭以用於交叉互連之目的。當時並不知道交叉互連前端封閉端子。在本發明之前，交叉互連前端封閉端子的重要障礙為不能將電纜金屬接地(及電纜絕緣屏蔽層)與連接裝置之外部半導體層電隔離。本發明之至少一實施例解決了此問題。藉由在前端封閉端子處交叉互連電纜，如本發明中所進行，可不必產生用於在長距離分佈電纜電路中交叉互連之接頭。交叉互連本發明之前端封閉端子比先前使用之交叉互連接頭較佳，因為連接裝置係處於地上，而電纜接頭處於地下且經受濕氣及機械損壞。此外，由於前端封閉端子處於地上，所以較容易定位及修理。本發明之至少一實施例之額外益處在於：連接裝置為可分離的，且可充當將用於偵測故障裝置之極敏感設備的「測試點」。Prior to the present invention, in applications such as wind farms, which required long distance distribution cable circuits typically greater than 1,000 angstroms, joints were created in the cable for cross interconnection purposes. It was not known at the time that the cross-connected front end closed terminals. Prior to the present invention, an important obstacle to cross-connecting the front end of the terminal was the inability to electrically isolate the cable metal ground (and cable insulation shield) from the outer semiconductor layer of the connector. At least one embodiment of the present invention addresses this problem. By interconnecting the cables at the front end closed terminals, as is done in the present invention, it is not necessary to create joints for cross interconnections in long distance distribution cable circuits. Cross-interconnecting prior to the invention, the closed end of the terminal is earlier thanCross-connecting connectors are preferred because the connecting device is on the ground and the cable connector is underground and subject to moisture and mechanical damage. In addition, since the front end closed terminal is on the ground, it is easier to locate and repair. An additional benefit of at least one embodiment of the present invention is that the connecting device is detachable and can act as a "test point" for extremely sensitive devices that will be used to detect faulty devices.
儘管已出於描述較佳實施例的目的在本文中說明且描述特定實施例，但一般熟習此項技術者將瞭解，在不脫離本發明之範疇的情況下，廣泛多種替代及/或等效實施可取代所展示且描述之特定實施例。本申請案意欲涵蓋本文中所論述之較佳實施例的任何調適或變化。因此，顯然希望本發明僅受本發明之申請專利範圍及其等效物限制。Although the specific embodiments have been illustrated and described herein for the purpose of describing the preferred embodiments of the present invention, it will be understood by those skilled in the art Implementations may be substituted for the specific embodiments shown and described. This application is intended to cover any adaptations or variations of the preferred embodiments discussed herein. Therefore, it is apparent that the invention is limited only by the scope of the invention and its equivalents.
