Description
Technical field
The utility model relates to electric power tool, specifically relates to a kind of Zinc-Oxide Arrester live testing termination.
Background technology
Zinc-Oxide Arrester obtains widely applying in power system transformer substation mainly as the protection equipment of important power equipment anti-overvoltages such as transformer, bus, circuit.Outdoor Zinc-Oxide Arrester is installed external not high usually, directly manual wiring of testing crew.The common installation site of indoor Zinc-Oxide Arrester is higher, not by other servicing units, testing crew often can't directly be finished wiring work, at this moment, testing crew need be finished live testing wiring work by aids such as insulating ladders, for finish live testing of a lightning arrester need the staff up and down insulating ladder each once, and need be by special messenger's staircase to guarantee staff's safety of ladder up and down, both there had been potential safety hazard, waste of manpower resource again.The Zinc-Oxide Arrester number that install a 110kV and above electric pressure substation often reaches tens, up to a hundred individual, for often needing to move Insulation ladder, the Zinc-Oxide Arrester live testing task of finishing this electric pressure transformer station reaches tens and even up to a hundred inferior, workload is big, and test efficiency is low.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of easy to operate, workload is little, test efficiency is high Zinc-Oxide Arrester live testing termination is provided.
The purpose of this utility model realizes by following approach:
Zinc-Oxide Arrester live testing termination, its structural feature are, insulation long tube, insulated tension pole, wiring anchor clamps and actuation means; The wiring anchor clamps include anchor clamps and lower clamp, the insulation axial hollow of long tube and external to an end opening, and insulated tension pole is built in the hollow cavity of insulation long tube, and the openend of insulation long tube is extended in an end; Last anchor clamps one end is fixed on the periphery of insulation long tube openend along last, one end of lower clamp and insulated tension pole expose to the insulation long tube the end hinged, the center section of last anchor clamps and lower clamp is connected with articulated element and return member respectively, and the free end of last anchor clamps and lower clamp is interlocking pattern under normal conditions; Actuation means is connected with the other end of insulated tension pole.
Like this, last anchor clamps are stationary fixture, and lower clamp can be in the drive lower edge of insulated tension pole the two pin joint rotate, and be fulcrum with the articulated element, realize operating with unclamping with interlock of last anchor clamps.Concrete, actuation means acts on the insulated tension pole, makes insulated tension pole axially mobile backward along the insulation long tube, rotates thereby drive lower clamp, its free end is away from last anchor clamps, be releasing orientation, put Zinc-Oxide Arrester lead-in wire into this occlusion portion, by the actuation means acting in opposition on insulated tension pole, under the booster action of return member, the lower clamp playback realizes interlock with last anchor clamps, clamps the Zinc-Oxide Arrester lead-in wire, carries out Distance Test wiring operation by the insulation long tube then.
The utility model is applicable to that ground lead is duralumin row's Zinc-Oxide Arrester, adopted the remote-controlled operation instrument, operate in the face of the wiring of high-order Zinc-Oxide Arrester live testing with can be implemented in, single unit system is simple in structure, easy to operate, save manpower and materials, reduced workload, improved work efficiency.Simultaneously for realizing stable the obtaining of Zinc-Oxide Arrester wire current, the activity bases that the accuracy of raising live testing and the test efficiency of Zinc-Oxide Arrester live testing provide.
The utility model can further be specially:
Actuation means includes cross bar, rotating shaft and stationary installation, cross bar is horizontally through the insulation long tube, its part that is positioned at insulation long tube inner chamber is fixedlyed connected with insulated tension pole, the two ends of cross bar are the outer above and below that is exposed at the insulation long tube respectively, lower end is equipped with swivel arm, upper end is connected with stationary installation by rotating shaft, and stationary installation is fixedly connected on the outer peripheral face of insulation long tube.
By the swivel arm rotating horizontal pole, be rotating fulcrum with the rotating shaft that is connected on the stationary installation, insulated tension pole is under the drive of cross bar at this moment, and an angle to post deflection has produced a less displacement, and this displacement enough spurs lower clamp to open the wiring anchor clamps.Certainly, actuation means can also be a kind of handle, and structure is comparatively simple, perhaps is a kind of nut member, forms screw component with insulated tension pole, can realize aforesaid operations.
The other end of the relative openend of insulation long tube is equipped with the insulation gum cover.
This insulation gum cover is installed in the portion of the handle of insulation long tube, can be anti-skidding, and as lever.
In sum, be applicable to that ground lead is duralumin row's Zinc-Oxide Arrester, adopted the remote-controlled operation instrument, operate in the face of the wiring of high-order Zinc-Oxide Arrester live testing with can be implemented in, single unit system is simple in structure, and is easy to operate, saved manpower and materials, reduce workload, improved work efficiency.Simultaneously for realizing stable the obtaining of Zinc-Oxide Arrester wire current, the activity bases that the accuracy of raising live testing and the test efficiency of Zinc-Oxide Arrester live testing provide.
