The present invention proposes a kind of power line, and the power line has current leakage detection conductor, is applied to the power line with facilitatingIn electrical cord assembly with electric leakage self-checking function.
As shown in figure 1, the power line includes that the first wire 10, the second wire 20, the first conductive powder layer 61, second are conductivePowder bed 62, insulating part 40 and current leakage detection conductor 50.Wherein, the first wire 10 includes the first current-carrying core 11 and is wrapped in firstThe first insulating barrier 12 on the lateral wall of current-carrying core 11, the second wire 20 includes the second current-carrying core 21 and is wrapped in the second current-carrying core 21The second insulating barrier 22 on lateral wall；First conductive powder layer 61 is wrapped on the lateral wall of the first insulating barrier 12；Second is conductivePowder bed 62 is wrapped on the lateral wall of the second insulating barrier 22；Insulating part 40 has the first accommodating cavity 41, the first wire 10 and theTwo wires 20 are in the first accommodating cavity 41；Current leakage detection conductor 50 in the first accommodating cavity 41, current leakage detection conductor 50 withFirst conductive powder layer 61 and the second conductive powder layer 62 are electrically connected.
As illustrated in fig. 1 and 2, when the first insulating barrier 12 and/or the second insulating barrier 22 are damaged, the first current-carrying core 11 and/orSecond current-carrying core 21 will from the first insulating barrier 12 and/or the second insulating barrier 22 it is impaired from produce electrical leakage problems, it is and of the inventionBy corresponding to the first conductive powder layer of parcel respectively on the lateral wall of the lateral wall of the first insulating barrier 12 and the second insulating barrier 2261 and second conductive powder layer 62 so that the first current-carrying core 11 and/or the second current-carrying core 21 are in the first insulating barrier 12 and/or secondThe impaired place of insulating barrier 22 contacts with the first conductive powder layer 61 and/or the second conductive powder layer 62, and the first conductive powder layer61 and second conductive powder layer 62 again electrically connected with current leakage detection conductor 50, in this way, current leakage detection conductor 50 can accurately,The leaky of the first wire 10 and the second wire 20 is found in time, then by tripping mechanism deenergization in time, is examinedCurrent leakage detection conductor 50 is usually to detect voltage or curent change in considering the present invention, and above-mentioned tripping mechanism is preferably electromagnetismTripping mechanism.
The first conductive powder layer 61 and the second conductive powder layer 62 in due to the present invention are powdered structures, in this way,When the first insulating barrier 12 and/or the second insulating barrier 22 are damaged, and when the breakage is only small damaged crackle, first leadsElectro-powder layer 61 and/or the second conductive powder layer 62 can also enter the impaired place and be carried with the first current-carrying core 11 and/or secondStream core 21 is contacted such that it is able to find the leaky of the first wire 10 and the second wire 20 in good time.
It is noted that live wire and zero line in the wire 20 of the first wire 10 and second typically power line, in this way,Power line in the present invention can effectively prevent the first wire 10 and the second wire 20 from producing short circuit problem caused by electric leakage simultaneously,In case there is fire；Or first wire 10 and/or the second wire 20 produce leaky, and insulating part 40 it is also damaged when, leadThe problem for causing power line externally to leak electricity, in case causing people and animals to get an electric shock.
Preferably, the first conductive powder layer 61 and the second conductive powder layer 62 are graphite powder last layer or metal powder in the present inventionLast layer.The characteristics of there is good chemical stability, heat-resisting quantity, high adsorption and small density due to graphite powder, therefore this hairThe first conductive powder layer 61 and the second conductive powder layer 62 in bright are preferably graphite powder.
Specifically, graphite powder last layer Electrostatic Absorption is set on the outer wall of the first insulating barrier 12 and/or the second insulating barrier 22,In this way, graphite powder can be stably adsorbed on the outer wall of the first insulating barrier 12 and/or the second insulating barrier 22, so as to ensure that electricityThe stability of source cable architecture and performance.Certainly, in other embodiments, may also set up metal powder layer and be plated on the first insulating barrier12 and/or second insulating barrier 22 outer wall on, in this way, can realize metal powder layer be stably attached to the first insulating barrier 12 and/Or second insulating barrier 22 outer wall on, so as to ensure the stability of power line structure and performance.
As shown in Fig. 2 the conductive powder layer 61 of current leakage detection conductor 50 and first and the second conductive powder layer 62 in the present inventionThe concrete structure of electrical connection, can by set current leakage detection conductor 50 simultaneously with the first conductive powder layer 61 and the second conductive powderThe mode of the contact of layer 62 is realized.Specifically, settable current leakage detection conductor 50 is held on the first conductive powder layer 61 and second and leadsBetween electro-powder layer 62, the structure is compact, the stability of power line structure in the present invention is can effectively ensure that, so as to ensureThe performance of detection of electrical leakage.
As illustrated in fig. 1 and 2, in another embodiment of the invention, the first conductive powder layer 61 and second is may also set up to leadElectro-powder layer 62 is contacted, in this way, need to only set the conductive powder layer 61 of current leakage detection conductor 50 and first and the second conductive powder layerA contact in 62, you can realize the electricity of the conductive powder layer 61 of current leakage detection conductor 50 and first and the second conductive powder layer 62Connection；Certainly current leakage detection conductor 50 is set to be contacted simultaneously more preferably with the first conductive powder layer 61 and the second conductive powder layer 62,In this way, multi-ensuring can be provided, it is ensured that the conductive powder layer 61 of current leakage detection conductor 50 and first and the second conductive powder layerThe stability of 62 electrical connections, effectively improves the detection of electrical leakage performance of power line in the present invention.
Preferably, current leakage detection conductor 50 may be selected conductor wire, such as copper cash or aluminum steel, and this is relatively simple for structure, and ratioIt is more practical.In order to strengthen the accuracy of detection of electrical leakage, can be set many conductor wires, and set many conductor wires be spaced apart inIn insulating part 40.Certainly, current leakage detection conductor 50 is also dependent on needing to be arranged to other shapes, such as sheet, bulk, ring-type or pipeShape, so, it is possible to increase the contact surface of the conductive powder layer 61 of current leakage detection conductor 50 and first and/or the second conductive powder layer 62Product, improves the detection of electrical leakage performance of power line in the present invention.
It is noted that general, the power line substantially strip in the present invention, and with windability；FirstThe two ends of the wire 20 of wire 10 and second are typically to expose the first current-carrying core 11 and the second current-carrying core 21, in this way, can be convenientlyThe power line and other parts are assembled into an electrical cord assembly.
As illustrated in fig. 1 and 2, in order to strengthen the security performance of power line in the present invention, it is ensured that use the electrical equipment of the power lineThe Electrical Safety of equipment, the power line set in the present invention also includes the privates 30 in the first accommodating cavity 41, and thisThree wires 30 are used to be grounded, and the privates 30 includes the 3rd current-carrying core 31 and be wrapped on the lateral wall of the 3rd current-carrying core 31 theThree insulating barriers 32, in this way, can be conveniently done ground protection using the part metals body of the electric equipment of the power line, preventElectric leakage causes personal safety hidden danger.
