Technical field
The utility model relates to electric power live testing auxiliary connection instrument, specifically relates to a kind of transformer substation arrester live testing Special wiring bar.
Background technology
Lightning arrester, due to its through-flow characteristic, obtains widespread use in transformer station.The lightning arrester number that install 110kV and above substation often reaches more than tens.Highly be less than the lightning arrester live-line test of 1.8 meters for lead-in wire, personnel can not need auxiliary connection device, directly directly complete manual wiring by tester and work.And be highly greater than the lightning arrester live-line test of 1.8 meters for lead-in wire, tester need to complete live testing wiring work by aids such as insulating ladders, need the upper and lower insulating ladder of staff respectively once for completing live testing of a lightning arrester, there is huge potential safety hazard, and be that the lightning arrester live-line test task of a 110kV and above transformer station often needs to move Insulation ladder and reaches tens and even up to a hundred times, complex operation, workload is large, inefficiency.
Summary of the invention
The purpose of this utility model be according to the deficiencies in the prior art part provide a kind of simple to operate, workload is little, the transformer substation arrester live testing Special wiring bar that work efficiency is high.
The purpose of this utility model realizes by following approach:
Transformer substation arrester live testing Special wiring bar, its structural feature is, includes fixing mouth pincers, movable nozzle pincers, insulation round bar and motion bar; Insulation round bar is a kind of circular ring type hollow stem, and motion bar is arranged in the inner chamber of insulation round bar, and the head of motion bar and afterbody all expose to outside insulation round bar; Fixing mouth pincers are fixedly connected with the head outer peripheral face of insulation round bar by spud pile, and movable nozzle pincers are fixedly connected with the head of motion bar, are connected with a movable latch closure at the afterbody of motion bar; On the outside surface of insulation round bar or spud pile, connecting ring is installed.
Described motion bar is coaxial concentric loop bar with insulation round bar, motion bar can move forward and backward along axis in the inner chamber of insulation round bar, and drives movable nozzle pincers near fixing mouth pincers, realizes clamped condition, or drive movable nozzle pincers away from fixing mouth pincers, withdraw from clamped condition.Transformer substation arrester live testing Special wiring bar described in the utility model in use, pull movable latch closure, movable nozzle pincers are pulled away to fixing mouth pincers, then arrester ground downlead is put into and clamped and fix mouth by movable nozzle and clamp the jaw forming, now motion bar drives movable nozzle pincers near fixing mouth pincers, closed jaw, clamps down conductor.Finally by insulation round bar, the jaw with down conductor is guided to assigned address, complete the connection of down conductor.Connection operating lever described in the utility model is simple in structure, easy to operate, can alleviate lightning arrester live-line test workload, and work efficiency is improved greatly.
The utility model can further be specially:
Also include spring and spring stop, spring stop is a kind of annulus, it is positioned at the inner chamber of insulation round bar, and be fixed on the inner peripheral surface of insulation round bar, and spring housing is trapped among motion bar and is positioned at the leading section of insulation round bar inner chamber, one end of spring is fixed on motion bar, and the other end is fixed on spring stop.
Under the restriction of spring stop, spring priming motion bar, to the direction activity near fixing mouth pincers, also drives movable nozzle pincers near fixing mouth pincers simultaneously, and when after jaw closure, due to the restriction of fixing mouth pincers, spring cannot stretch again, in Pre strained state.That is to say, under normal conditions, jaw is normally closed under the effect of spring.Only pull movable latch closure ability Compress Spring, drive motion bar and movable nozzle pincers away from fixing mouth pincers, and unclamp after movable latch closure, movable nozzle pincers will drive at spring under the effect of motion bar, automatically revert to the state closing with fixing mouth icarceration.Like this, under the pretension effect of spring, can guarantee the fixed clamp effect of jaw to down conductor, and be conducive to completing smoothly of wiring, therefore be conducive to the stable Leakage Current that obtains the arrester ground lead-in wire of flowing through, improve lightning arrester live-line test data accuracy.
Also include fixing base ring, this fixing base ring by fixed pedestal be arranged on insulation round bar tail end, now loose collar button bit in the inner ring of this fixing base ring, the parallel distribution of the portion of the handle of the two.
Like this, when loose collar is buckled in operation, just can, under the restriction of fixing base ring, there is moving around of control.The parallel distribution of portion of the handle is in the time operating, and can pull movable latch closure for supporting by fixing base ring, realizes one-handed performance, makes to operate more convenient, quick.
In sum, the utility model provides a kind of transformer substation arrester live testing Special wiring bar, simple in structure, easy to operate, can alleviate lightning arrester live-line test workload, work efficiency is improved greatly, be conducive to the stable Leakage Current that obtains the arrester ground lead-in wire of flowing through, improve lightning arrester live-line test data accuracy.
Accompanying drawing explanation
Figure 1 shows that the structural representation of transformer substation arrester live testing Special wiring bar described in the utility model.
Below in conjunction with embodiment, the utility model is described further.
