A pull ring is arranged at the end of the insulating pull ring. A fixed ring is arranged at the end of the insulating sleeve. A pair of stationary pincers is fixed at the other end of the insulating sleeve. A pair of moveable pincers reciprocating along with the insulating pull rod is fixed at the same end of the insulating pull rod. In a normal state, the stationary and moveable pincers are matched in a clamped state. The stationary and moveable pincers are made of conductive materials. The pair of moveable pincers is provided with a conductive junction ring. The insulating pull ring between the moveable pincers and the insulating sleeve is sleeved with a return spring. The junction device of the charged testing experiment of the metallic oxide lightning arrester is beneficial for alleviating the work load of the charged test of the a metallic oxide lightning arrester, so that the work efficiency of the charged test of the a metallic oxide lightning arrester is improved.
Description
Technical field
The utility model relates to a kind of termination, particularly a kind of metal oxide arrester live testing test connection device.
Background technology
Metal oxide arrester has good nonlinear characteristic and through-current capability, can protect high voltage electric equipment to avoid superpotential infringement.Therefore, metal oxide arrester has obtained to use widely in each electric pressure transformer station as the protection equipment of high voltage electric equipment.
The metal oxide arrester quantity that 220kV and above electric pressure transformer station install often reaches tens to up to a hundred; The live testing personnel are undertaken by 2 people usually; The live testing time is short; On-the-spot metal oxide arrester is installed in overhead 2 meters to 2.5 meters height place usually, and testing crew need be accomplished live testing wiring work by means of Insulation ladder.Therefore, accomplish the metal oxide arrester live testing work of a 220kV and above electric pressure transformer station and often need move the Insulation ladder number of times up to tens to up to a hundred times, the testing crew workload is heavy, causes the live testing inefficiency.
The utility model content
The purpose of the utility model is to overcome the weak point of prior art; And a kind of operating load that alleviates the metal oxide arrester live testing is provided; Improve the operating efficiency of metal oxide arrester live testing; Can realize simultaneously the stable leakage current that obtains the metal oxide of flowing through again, improve a kind of metal oxide arrester live testing test connection device of metal oxide arrester live testing result's accuracy.
A kind of metal oxide arrester live testing test connection device; Include insulating sleeve and insulated tension pole, insulating sleeve is placed in outside the insulated tension pole, and insulated tension pole can move reciprocatingly along the axis direction of insulating sleeve; End at insulated tension pole is provided with draw ring; End at insulating sleeve is provided with retainer ring, is fixed with actionless quiet pincers in the other end of insulating sleeve, is fixed with one in the same side of insulated tension pole and follows the moving pincers that insulated tension pole moves reciprocatingly; Moving pincers and quiet pincers match when normality and are in clamped condition; Moving pincers and quiet pincers also are provided with the conductive connection ring that is used for fixing metal oxide arrester live testing test wire clamp for to be processed by electric conducting material on moving pincers, moving clamp and insulating sleeve between insulated tension pole on be arranged with return spring; One end of spring links to each other with moving pincers, and the other end of spring is supported in the end of insulating sleeve.
The metal oxide arrester live testing test connection device of this structure; In use; With metal oxide arrester live testing test wire clamping connection on termination wiring ring obtaining the leakage current of the metal oxide arrester of flowing through, the draw ring through termination insulated tension pole end drives the relative insulating sleeve of pull bar and moves, the pull bar of motion drives moving pincers on its other end and follows one of which and play motion; The moving pincers of motion are compression retracteding position spring again; When moving pincers and quiet pincers are dehisced to a certain degree the time, between the two opening is sandwiched the lead-in wire of metal oxide on lightning-arrest, discharge external force; Moving pincers will be under the effect of spring restoring force return realize clamping lead-in wire and accomplish the live testing wiring, metal oxide arrester live testing instrument is gone in will the flow through leakage current drainage stably of metal oxide arrester of realization.
In sum, the utility model is compared the following advantage of prior art:
(1) the metal oxide arrester live testing test connection device of the utility model helps to alleviate the operating load of metal oxide arrester live testing, improves the operating efficiency of metal oxide arrester live testing.
(2) the utility model helps the stable leakage current that obtains the metal oxide of flowing through, and has improved metal oxide arrester live testing result's accuracy.
