Description
Technical field
The present invention relates to electric power live testing instrument, relate to particularly a kind of testing current in resistance property of lightning arrester instrument.
Background technology
Zinc-Oxide Arrester mainly, as the protection equipment of the important power equipment anti-overvoltages such as transformer, bus, circuit, is used widely in power system transformer substation.Outdoor zinc paste setting height(from bottom) is conventionally not high, directly manual wiring of testing crew; Indoor zinc paste installation site is conventionally higher, if not by auxiliary connection instrument, testing crew often cannot directly complete wiring work.In test process, testing crew need to complete live testing work by aids such as insulating ladders, and testing crew need to repeatedly carry out the climbing of insulating ladder, exists huge potential safety hazard; And the lightning arrester live-line test task that need to complete a 110kV and above transformer station often needs to move insulating ladder tens times and even up to a hundred time, workload is large, inefficiency.
Summary of the invention
The present invention, in order to overcome the deficiencies in the prior art, provides a kind of easy to operate, safe and reliable, the testing current in resistance property of lightning arrester instrument that work efficiency is high.
Technical scheme of the present invention is as follows:
A kind of testing current in resistance property of lightning arrester instrument, it comprises insulation long tube, insulated tension pole, wiring fixture and operation latch closure; Described insulation long tube is telescopic hollow structure, and to have one end be openend; In the cavity of insulation long tube, be built-in with insulated tension pole, insulated tension pole can be along insulation long-tube shaft to moving reciprocatingly; Described insulated tension pole is Collapsible structure; Described wiring fixture divides quiet pincers and moving pincers, between moving pincers and quiet pincers, is provided with articulated element and return member; One end of described quiet pincers is fixed on the other end relative with openend of insulation long tube; Yu Dongqian one end, one end of described insulated tension pole connects, and the other end is connected with operation latch closure; Described moving pincers and quiet pincers are under normal conditions in interlocking pattern.
Above-described insulation long tube arranges insulating gum cover with respect to the other end of openend.
When use, according to the residing height of lightning arrester, regulate the length of telescopic insulation long tube and insulated tension pole; Pull operation latch closure, insulated tension pole axially moves backward along insulation long tube, and the quiet pincers of wiring fixture are fixed on insulation long tube, and moving pincers pin joint along the two under the drive of insulated tension pole rotates, and take articulated element as fulcrum, realization is unclamped and interlock with quiet pincers.In the time being releasing orientation, lightning arrester lead-in wire is put into this interlock position, promote operation latch closure, insulated tension pole is mobile in the other direction, under the effect of return member, and moving pincers and quiet pincers interlock, clamp the lead-in wire of lightning arrester, then carry out Distance Test wiring operation by insulation long tube.
Compared with prior art, the present invention has the following advantages and beneficial effect:
1, insulation long tube of the present invention and insulated tension pole are Collapsible structure, can realize the remote-controlled operation to lightning arrester band electrical measurement wiring, have saved manpower and materials, reduce workload, increase work efficiency.
2, the present invention is simple in structure, easy to operate, safe and reliable, and production cost is low.
