Description

750kV testing current in resistance property of lightning arrester rapid wiring device
Technical field
The application relates to a kind of 750kV testing current in resistance property of lightning arrester rapid wiring device.
Background technology
Power equipment operationally, needs periodic detection equipment operation information, grasps its health status, guarantee power equipment safety stable operation.750kV lightning arrester just needs operationally to monitor resistive current component in its leakage current, and then judges the operation conditions of this lightning arrester.750kV leakage current of an arrester table meter installation site is higher, about 2.8 meters, average departure ground.During test wiring, it is high that personnel need to copy herringbone step stool mechanically, and touch the region of more than 2.8 meters with hand, and the wiring operation of ascending a height of personnel not only seriously reduces work efficiency, and significantly increases the security risk of personnel.
Summary of the invention
The object of the application is that proposing one completes 750kV testing current in resistance property of lightning arrester wiring work, the 750kV testing current in resistance property of lightning arrester rapid wiring device of increasing work efficiency fast, effectively, safely.
The object of the application is achieved in that 750kV testing current in resistance property of lightning arrester rapid wiring device, it comprises expansion link, described expansion link upper end is fixedly linked with the connector with screw rod, described screw rod upper end is provided with card line seat, described screw rod is also connected with can around card the end of a thread of bolt rotary, described card line seat is positioned at card the end of a thread, card the end of a thread and card line seat are provided with the first corresponding clamp groove and the second clamp groove, card the end of a thread and expansion link are respectively arranged with wiring point and utility outlets, are connected by connecting line circuit between wiring point with utility outlets.
The application has the following advantages: 1, its binding clip clamp is in leakage current of an arrester table meter upper end, can obtain the stable leakage current flowing through 750kV lightning arrester lead-in wire.2, its insulating telescopic bar inside has electrically conducting to test connecting line, for connecting end portion and root: end is connected to wiring clamp place by connecting elements; Root is provided with Φ 4mm utility outlets, can connecting test instrument connection plug fast.3, its insulating telescopic bar is the longest extending to 1m, is the shortlyest reduced to 0.3m.4, three devices are one group and concentrate and place, lightweight, volume is little, easy to carry, simple to operate, the work of three-phase lightning protector testing current in resistance property can be carried out simultaneously, while effectively increasing work efficiency, reduce the security risk of tester largely.5, this device can be applicable to 750kV and the wiring of following electric pressure testing current in resistance property of lightning arrester and leakage current of an arrester table meter and verifies wiring.
Accompanying drawing illustrates: the concrete structure of the application is provided by following drawings and Examples:
Fig. 1 is 750kV testing current in resistance property of lightning arrester rapid wiring device structural representation.
Legend: 1, card the end of a thread, the 2, first clamp groove, 3, wiring point, 4, connecting line, 5, wire hole, 6, testing tool, 7, utility outlets, 8, expansion link, 9, connector, 10, screw rod, 11, card line seat, the 12, second clamp groove.
Embodiment:
The application by the restriction of following embodiment, can not determine concrete embodiment according to the technical scheme of the application and actual conditions.
Embodiment: as shown in Figure 1,750kV testing current in resistance property of lightning arrester rapid wiring device comprises expansion link 8, described expansion link 8 upper end is fixedly linked with the connector 9 with screw rod 10, described screw rod 10 upper end is provided with card line seat 11, described screw rod 10 is also connected with the card the end of a thread 1 that can rotate around screw rod 10, described card line seat 11 is positioned at card the end of a thread 1, and card the end of a thread 1 and card line seat 11 are provided with the first corresponding clamp groove 2 and the second clamp groove 12.Card the end of a thread 1 and expansion link 8 are respectively arranged with wiring point 3 and utility outlets 7, are connected by connecting line 4 circuit between wiring point 3 with utility outlets 7.Described card line seat 11 can be fixedly linked with screw rod 10, also can be rotatedly connected.
Described card the end of a thread 1 is the semiclosed shaped as frame of open at one end, and wiring point 3 is arranged on the blind end of card the end of a thread 1.
Described expansion link 8 is insulating bar, and it is socketed successively by some joint insulating bars and forms, and it comprises head end insulating bar, end insulation bar and intermediate insulation bar.Be cavity in each insulating bar, bottom end insulation bar, be provided with Φ 4mm utility outlets 7, this utility outlets 7, in order to be connected with testing apparatus, is connected with connecting line 4 in utility outlets 7 the inner.
