随着经济的快速发展，电力已成为千家万户都离不开的能源，使得用电总量大幅增长。在用电高峰时，电力输配电线路和变电设备会出现满负荷甚至短时超负荷运行，进而导致设备和导线连接点温度过热，易造成烧断线和大面积停电事故。With the rapid development of the economy, electricity has become an inseparable source of energy for thousands of households, resulting in a substantial increase in total electricity consumption. During peak power consumption, power transmission and distribution lines and substation equipment will run at full load or even short-term overload, which will lead to overheating of equipment and connection points of wires, which will easily cause line burnout and large-scale power outages.
为保证电网安全运行，电力线路和设备运维人员目前主要采用定期巡视线路和设备，利用红外测温和热成像测温技术，记录所有接点温度。但是，利用红外测温和热成像测温技术测温，需要运维人员到线路和设备现场逐个对设备和线路接点进行测量，劳动强度大、工作效率低，且不能实时监测接点的温度。In order to ensure the safe operation of the power grid, power line and equipment operation and maintenance personnel currently mainly use regular patrol lines and equipment, and use infrared measurement and thermal imaging temperature measurement technology to record all junction temperatures. However, using infrared temperature measurement and thermal imaging temperature measurement technology to measure temperature requires operation and maintenance personnel to go to the line and equipment site to measure the equipment and line contacts one by one.
针对上述线路接点测温方式费时费力且实时性较差的问题，尚未提出有效的解决方式。Aiming at the problems of time-consuming and labor-intensive and poor real-time performance of the above-mentioned line contact temperature measurement method, no effective solution has been proposed yet.

当容纳于接线圆柱102的螺旋形凹槽内的接线端的温度没有超过预设阈值时，设置于感温腔104的开口处的温敏金属片108将驱动弹簧110顶部的卡扣装置112卡在感温腔104内部，上述驱动弹簧110处于压缩状态；当接线端温度超过预设阈值时，接线圆柱102将温度传导至设置于感温腔104的开口处的多个温敏金属片108，该温敏金属片发生形变，多个温敏金属片内部空间的直径大于卡扣装置的顶部直径；驱动弹簧110运动；与驱动弹簧110通过卡扣装置112连接的报警指示牌114从第二绝缘套筒106中伸出。When the temperature of the terminal contained in the spiral groove of the terminal cylinder 102 does not exceed the preset threshold, the temperature-sensitive metal sheet 108 arranged at the opening of the temperature-sensing chamber 104 will clamp the buckle device 112 on the top of the driving spring 110 Inside the temperature-sensing cavity 104, the driving spring 110 is in a compressed state; when the terminal temperature exceeds a preset threshold, the connecting cylinder 102 conducts the temperature to a plurality of temperature-sensitive metal sheets 108 arranged at the opening of the temperature-sensing cavity 104, the The temperature-sensitive metal sheet is deformed, and the diameter of the internal space of a plurality of temperature-sensitive metal sheets is larger than the top diameter of the buckle device; the driving spring 110 moves; Out of the barrel 106.
具体地，报警指示牌可以设置为醒目的颜色，例如，红色；当报警指示牌从第二绝缘套筒中伸出后，可以引起巡查人员的注意；同时，当该装置设置于户外的电力线路中时，报警指示牌上的风笛可以在风力的作用下，发出尖锐的笛声，进一步提醒巡查运维人员的注意。Specifically, the warning sign can be set to an eye-catching color, for example, red; when the warning sign stretches out from the second insulating sleeve, it can attract the attention of inspectors; In the middle, the bagpipe on the alarm sign can make a sharp flute sound under the action of wind force, further reminding the attention of the inspection and maintenance personnel.
本发明实施例提供的一种超温报警接线装置中，接线单元采用接线圆柱，将接线端容纳于该接线圆柱上的螺旋形凹槽中，增大了接线端的接线长度，降低了接线电阻；报警单元的感温腔设置于接线圆柱的凹陷腔中，可以及时地感知接线圆柱的温度变化，通过温敏金属片的形变使驱动弹簧运动，进而伸出报警指示牌和风笛，实现超温报警的作用。上述方式可以便捷地对线路接点进行超温报警，降低了运维人员的工作量，省时省力，且成本低廉。In an over-temperature alarm wiring device provided by an embodiment of the present invention, the wiring unit adopts a wiring cylinder, and the terminal is accommodated in a spiral groove on the wiring cylinder, which increases the wiring length of the terminal and reduces the wiring resistance; The temperature-sensing cavity of the alarm unit is set in the concave cavity of the wiring cylinder, which can sense the temperature change of the wiring cylinder in time, and the deformation of the temperature-sensitive metal sheet can make the driving spring move, and then extend the alarm sign and bagpipe to realize the over-temperature alarm role. The above method can conveniently alarm the over-temperature of the line contact, reduce the workload of the operation and maintenance personnel, save time and labor, and have low cost.
实施例二：Embodiment two:
为了对上述实施例一中提供的超温报警接线装置进行详细地描述，参见图2所示的图1沿V-V线的第一种剖视图；图2示出了多个温敏金属片的第一种设置方式，其中，多个温敏金属片108的数量为两个；温敏金属片108的两端均固定于感温腔104开口处的边缘位置；温敏金属片108两端的位置相对于感温腔相对立；具体地，两个温敏金属片108的长度可以与感温腔的直径相同，以使两个温敏金属片可以在不发生形变的情况下，恰好固定于感温腔开口的直径处。In order to describe in detail the over-temperature alarm wiring device provided in the first embodiment above, refer to the first cross-sectional view of FIG. 1 along the V-V line shown in FIG. 2; FIG. A kind of setting mode, wherein, the quantity of a plurality of temperature-sensitive metal sheets 108 is two; The two ends of temperature-sensitive metal sheets 108 are all fixed on the edge position of temperature-sensitive chamber 104 openings; The position of temperature-sensitive metal sheets 108 two ends is relative The temperature-sensing cavity is opposite; specifically, the length of the two temperature-sensitive metal sheets 108 can be the same as the diameter of the temperature-sensing cavity, so that the two temperature-sensitive metal sheets can be fixed in the temperature-sensing cavity without deformation. diameter of the opening.
上述两个温敏金属片平行设置；两个温敏金属片之间的距离小于卡扣装置的顶部直径；如图2(a)所示，由于两个温敏金属片之间的距离较小，因此可以抵住卡扣装置，使卡扣装置下的驱动弹簧处于压缩状态。The above two temperature-sensitive metal sheets are arranged in parallel; the distance between the two temperature-sensitive metal sheets is smaller than the top diameter of the buckle device; as shown in Figure 2 (a), since the distance between the two temperature-sensitive metal sheets is small , so it can resist the buckle device, so that the driving spring under the buckle device is in a compressed state.
当接线端温度超过预设阈值时，两个温敏金属片形变的方向相反，两个温敏金属片之间的距离变大，当温敏金属片之间的距离大于卡扣装置的顶部直径时，驱动弹簧运动；如图2(b)所示，温敏金属片可以为双金属片，通常有不同膨胀系数的两种金属压制而成；温度升高时，温敏金属片伸长，由于温敏金属片的两端固定，因而两个温敏金属片的形变方向均朝向感温腔的边缘；两个温敏金属片之间的空间变大；当空间的直径大于卡扣装置的顶部直径时，卡扣装置以及驱动弹簧失去压力，驱动弹簧可以伸长至无压缩状态。When the terminal temperature exceeds the preset threshold, the deformation direction of the two temperature-sensitive metal sheets is opposite, and the distance between the two temperature-sensitive metal sheets becomes larger. When the distance between the temperature-sensitive metal sheets is greater than the top diameter of the buckle device , the drive spring moves; as shown in Figure 2(b), the temperature-sensitive metal sheet can be a bimetal sheet, which is usually pressed by two metals with different expansion coefficients; when the temperature rises, the temperature-sensitive metal sheet elongates, Since the two ends of the temperature-sensitive metal sheets are fixed, the deformation directions of the two temperature-sensitive metal sheets are all towards the edge of the temperature-sensing chamber; the space between the two temperature-sensitive metal sheets becomes larger; when the diameter of the space is larger than the buckle device When the top diameter is lower, the buckle device and the drive spring lose pressure, and the drive spring can be stretched to an uncompressed state.
参见图3所示的图1沿V-V线的第二种剖视图；图3示出了多个温敏金属片的第二种设置方式，其中，多个温敏金属片的数量为两个以上(图3中，(a)和(b)以温敏金属片的数量为两个为例；(c)和(d)以温敏金属片的数量为四个为例)；温敏金属片的长度小于感温腔的直径；温敏金属片的一端固定于感温腔开口处的边缘位置；温敏金属片的另一端位于感温腔开口的中心位置附近；多个温敏金属片的一端均匀分布于感温腔开口处的边缘；多个温敏金属片的另一端之间形成的空间内径小于卡扣装置的顶部直径。Referring to the second cross-sectional view of Fig. 1 along the V-V line shown in Fig. 3; Fig. 3 shows a second arrangement of multiple temperature-sensitive metal sheets, wherein the number of multiple temperature-sensitive metal sheets is more than two ( Among Fig. 3, (a) and (b) take the quantity of temperature-sensitive metal sheets as two examples; (c) and (d) take the quantity of temperature-sensitive metal sheets as four examples); The length is smaller than the diameter of the temperature sensing chamber; one end of the temperature sensitive metal sheet is fixed at the edge of the opening of the temperature sensing chamber; the other end of the temperature sensitive metal sheet is located near the center of the opening of the temperature sensing chamber; one end of multiple temperature sensitive metal sheets Evenly distributed on the edge of the opening of the temperature-sensitive cavity; the inner diameter of the space formed between the other ends of the multiple temperature-sensitive metal sheets is smaller than the top diameter of the buckle device.
具体地，当温敏金属片的数量为两个时，两个温敏金属片固定于感温腔边缘的一端对立分布；两个温敏金属片的活动端位于感温腔开口的中心位置附近，该中心位置附近可以为卡扣装置的顶部，以起到抵住卡扣装置的目的。当温敏金属片的数量为多个时(例如，四个)，两个温敏金属片固定于感温腔边缘的一端两两对称分布；四个温敏金属片的活动端位于感温腔开口的中心位置附近，该中心位置附近也可以为卡扣装置的顶部，以起到抵住卡扣装置的目的。Specifically, when the number of temperature-sensitive metal sheets is two, the two temperature-sensitive metal sheets are fixed at one end of the edge of the temperature-sensitive chamber and are oppositely distributed; the movable ends of the two temperature-sensitive metal sheets are located near the center of the opening of the temperature-sensitive chamber , the vicinity of the central position may be the top of the buckle device, so as to resist the buckle device. When the number of temperature-sensitive metal sheets is multiple (for example, four), two temperature-sensitive metal sheets are fixed on one end of the edge of the temperature-sensitive chamber and distributed symmetrically; the movable ends of the four temperature-sensitive metal sheets are located in the temperature-sensitive chamber. The vicinity of the central position of the opening may also be the top of the buckle device, so as to resist the buckle device.
当接线端温度超过预设阈值时，多个温敏金属片形变的方向均朝向感温腔开口处的边缘，多个温敏金属片之间的距离变大，当多个温敏金属片之间的距离大于卡扣装置的顶部直径时，驱动弹簧运动。When the terminal temperature exceeds the preset threshold, the deformation directions of multiple temperature-sensitive metal sheets are all towards the edge of the opening of the temperature-sensing cavity, and the distance between multiple temperature-sensitive metal sheets becomes larger. When the distance between them is greater than the top diameter of the buckle device, the drive spring moves.
在实际应用中，巡查运维人员看到伸出的报警牌后，进行接线处的维修，维修完成时，接线装置温度下降为正常值，上述两个或者多个温敏金属片的形状恢复；恢复原状后的多个温敏金属片之间的空间变小，内径小于卡扣装置顶部的内径；运维人员手动将卡扣装置推回感温腔内部，温敏金属片以下时，温敏金属片又将卡扣装置压在感温腔内部，驱动弹簧处于压缩状态，因此该装置可以重复使用，具有较高的实用性。In practical application, after seeing the protruding alarm board, the inspection operation and maintenance personnel will repair the wiring. When the maintenance is completed, the temperature of the wiring device will drop to a normal value, and the shape of the above two or more temperature-sensitive metal sheets will be restored; The space between multiple temperature-sensitive metal sheets after restoration to the original shape becomes smaller, and the inner diameter is smaller than the inner diameter of the top of the buckle device; the operation and maintenance personnel manually push the buckle device back to the inside of the temperature-sensing cavity. The metal sheet presses the buckle device inside the temperature sensing cavity, and the driving spring is in a compressed state, so the device can be used repeatedly and has high practicability.
参见图4所示的一种超温报警接线装置处于报警状态的结构示意图；装置中，卡扣装置112与报警指示牌114之间设置有连接部件400；该连接部件400包括铰链连接部件；报警指示牌114从第二绝缘套筒106中伸出后，报警指示牌通过铰链连接部件的转动改变方向。Referring to the structural diagram of an over-temperature alarm wiring device in an alarm state shown in Figure 4; in the device, a connecting part 400 is arranged between the buckle device 112 and the warning sign 114; the connecting part 400 includes a hinge connecting part; After the indicator board 114 protrudes from the second insulating sleeve 106, the direction of the warning indicator board changes through the rotation of the hinge connecting part.
具体地，当该超温报警接线装置用于接线端之间的连接时，该装置的顶部的朝向可能与大地平行，也可能与大地垂直，因此采用铰链连接部件连接报警指示牌可以使因接线端超温导致报警指示牌伸出第二绝缘套筒时，报警指示牌处于较低的位置，便于巡查运维人员发现报警指示牌。进一步地，当该装置的顶部的朝向与大地平行时，报警指示牌伸出第二绝缘套筒后，铰链连接部件弯折，使报警指示牌垂直悬挂在导线节点处，运维人员在100米内就可发现。Specifically, when the over-temperature alarm wiring device is used for connection between terminals, the orientation of the top of the device may be parallel to the earth or perpendicular to the earth. When the over-temperature at the end causes the alarm indicator to protrude from the second insulating sleeve, the alarm indicator is at a lower position, which is convenient for inspection and maintenance personnel to find the alarm indicator. Further, when the orientation of the top of the device is parallel to the earth, after the alarm sign extends out of the second insulating sleeve, the hinge connection part is bent, so that the alarm sign is vertically hung at the node of the wire, and the operation and maintenance personnel can within 100 meters can be found.
另外，上述第二绝缘套筒可以由软性材料构成，例如橡胶，也可以有硬性材料构成，例如，塑料。In addition, the above-mentioned second insulating sleeve may be made of a soft material, such as rubber, or may be made of a hard material, such as plastic.
进一步地，上述卡扣装置112的形状为圆锥形、圆台形或者子弹头形，(图1和图4中所示的卡扣装置为圆台形)；上述形状的顶部直径均大于卡扣装置的底部直径，因而，当运维人员将卡扣装置推回感温腔内部时，卡扣装置可以轻易地通过多个温敏金属片之间的狭小空间。进一步，卡扣装置的顶部可以为平面，也可以优选地设置为微凸状弧形，方便卡扣装置的弹出。Further, the shape of the above-mentioned buckle device 112 is conical, truncated conical or bullet-shaped, (the buckle device shown in Fig. 1 and Fig. 4 is a truncated cone shape); Therefore, when the operation and maintenance personnel push the buckle device back into the temperature sensing cavity, the buckle device can easily pass through the narrow space between multiple temperature-sensitive metal sheets. Further, the top of the buckle device can be flat, or preferably in a slightly convex arc shape, so as to facilitate the ejection of the buckle device.
参见图5所示的接线圆柱的外部结构示意图；该接线圆柱的第一种外部结构为：接线圆柱上设置有单轨道螺旋形凹槽(图5中实线所表示出的螺旋形凹槽)；单轨道螺旋形凹槽的匝数为2圈以上。通过设置多匝数的螺旋形凹槽，一方面可以稳固地实现接线，另一方面可以是感温腔准确地感知接线端的温度。Referring to the schematic diagram of the external structure of the wiring cylinder shown in Figure 5; the first external structure of the wiring cylinder is: the wiring cylinder is provided with a single-track spiral groove (the spiral groove shown by the solid line in Figure 5) ; The number of turns of the single-track spiral groove is more than 2 turns. By setting the spiral groove with multiple turns, on the one hand, the connection can be realized stably, and on the other hand, the temperature sensing cavity can accurately sense the temperature of the terminal.
该接线圆柱的第二种外部结构为：接线圆柱上设置有双轨道螺旋形凹槽(图5中实线所表示出的螺旋形凹槽与虚线所表示出的螺旋形凹槽)；双轨道螺旋形凹槽的匝数为2圈以上；不同轨道的螺旋形凹槽之间的距离不小于螺旋形凹槽的宽度，可以使不同轨道内的接线端保持一定的距离，避免意外接触导致电阻瞬间增大，对电网设备造成负面影响。同时，双轨道螺旋形凹槽的出线口之间应保持一定的距离，该距离最好为螺旋形圆柱州长的四分之一至二分之一之间。The second external structure of the wiring cylinder is: the wiring cylinder is provided with a double-track spiral groove (the spiral groove shown by the solid line and the spiral groove shown by the dotted line in Figure 5); The number of turns of the spiral groove is more than 2 turns; the distance between the spiral grooves of different tracks is not less than the width of the spiral groove, which can keep the terminals in different tracks at a certain distance and avoid accidental contact causing resistance Instantaneous increase, causing negative impact on power grid equipment. Simultaneously, a certain distance should be kept between the outlets of the double-track spiral grooves, preferably between 1/4 and 1/2 of the length of the spiral cylinder.
参见图6所示的一种超温报警接线装置的具体结构示意图；为了使接线圆柱固定，且与感温腔紧密接触，感温腔104底部沿接线圆柱方向设置有固定中心柱600；接线圆柱中心位置设置有与固定中心柱内径相匹配的圆柱形空腔602；接线圆柱插入固定中心柱600后，固定中心柱的末端旋入螺母604，以使接线圆柱的位置固定。通过上述方式可以是接线圆柱固定在第一绝缘套筒的内部，且使接线圆柱与感温腔稳定低紧密接触，进而提高温度感知的灵敏度和准确度。Refer to the specific structural diagram of an over-temperature alarm wiring device shown in Figure 6; in order to fix the wiring cylinder and closely contact with the temperature sensing chamber, the bottom of the temperature sensing chamber 104 is provided with a fixed central column 600 along the direction of the wiring cylinder; the wiring cylinder The center position is provided with a cylindrical cavity 602 matching the inner diameter of the fixed central column; after the connecting column is inserted into the fixed central column 600, the end of the fixed central column is screwed into a nut 604 to fix the position of the connecting column. Through the above method, the wiring cylinder can be fixed inside the first insulating sleeve, and the wiring cylinder can be in stable and close contact with the temperature sensing cavity, thereby improving the sensitivity and accuracy of temperature sensing.
参见图7所示的图1沿V-V线的第三种剖视图；感温腔的边缘外设设置有设备连接部件700；该设备连接部件700与设备连接。通常，当超温报警接线装置是用于电力线路与设备之间的接线时，电力线路的接线端接入接线圆柱的螺旋形凹槽内，设备接入设备连接部件中；接线端与设备之间通过接线圆柱和感温腔的传导进行电力传输。Referring to the third cross-sectional view of FIG. 1 along the line V-V shown in FIG. 7 ; a device connecting part 700 is arranged on the periphery of the temperature sensing chamber; the device connecting part 700 is connected to the device. Usually, when the over-temperature alarm wiring device is used for wiring between the power line and the equipment, the terminal of the power line is inserted into the spiral groove of the wiring cylinder, and the equipment is inserted into the connecting part of the equipment; the connection between the terminal and the equipment The power transmission is carried out through the conduction between the connecting cylinder and the temperature sensing cavity.
