A telescopic insulating rod is sleeved in an insulating tube; a hook for being connected with the base lead of the lightning arrester to transmit an electric signal is installed in the hole of the telescopic insulating rod; an insulating clapboard is fixed on the end part of the telescopic insulating rod; and a waist-shaped adjusting hole is disposed at a position which the telescopic insulating rod is corresponding to the hook. The live test rod for a lightning arrester disclosed by the utility model can efficiently achieve mandatory requirements on safe distance between person and charged body in live work specified in 'Working Regulation of Electrical Safety', ensure the safe distance in operation, enhance the safety and reliability coefficients of live work for operating personnel, and act critical protection on personal safety; simultaneously, live test can be performed on the electrical parameters of metal oxide lightning arresters having a voltage class of 35 KV and tests for 110 KV and 220 KV lightning arresters can be satisfied by adjusting the length of the insulating rod and the distance between the insulating clapboard and the hook, therefore, the insulating rod acts a function of being multipurpose.
Description
Technical field
The utility model relates to the power test technical field of tools, is the reference test bar of the charged detection usefulness of a kind of high-voltage arrester specifically.
Background technology
Electric system is annual, particularly before thunderstorm season, needs the lightning arrester of 35KV of transformer station and above electric pressure is carried out live line measurement.During measurement, directly be connected to test wire on the lightning arrester base, measurement data is fed back to testing tool through test contact instrument.But because the lightning arrester of the 35KV of 110KV transformer station electric pressure employing at present is composite insulator; Its significant height is a 0.4-0.5 rice; Be that distance between its bottom (instrument highest point during measurement) and electrified body is a 0.4-0.5 rice, do not meet the mandatory provision of " safe distance during hot line job between the person and electrified body is greater than 0.6 meter " of defined in " State Grid Corporation of China's electric power safety working regulation (power transformation part) ".The dielectric strength of testing tool and the safe distance of charged work directly have influence on the security of hot line job.
Summary of the invention
For overcoming the deficiency of prior art; The goal of the invention of the utility model is to provide a kind of lightning arrester live testing bar; Through between lightning arrester bottom and test wire, setting up the Insulation test bar, the purpose that guarantees personal safety during with the dielectric strength that realizes improving testing tool and charged work.
For realizing above-mentioned purpose; Be with telescopic insulating bar in the insulation tube of the utility model; The hook that is used for being connected with lightning arrester base lead-in wire transmission of electric signals is contained in the hole of telescopic insulating bar; The end of telescopic insulating bar is fixed with insulating barrier, and telescopic insulating bar has the adjusting mounting hole with the corresponding position of hook.
The insulating barrier of the utility model, insulation tube, telescopic insulating bar all adopt insulating material; Telescopic insulating bar can according to the safe distance between the person and electrified body requirement stretch; Regulate the distance of insulating barrier and hook, simultaneously, realize the seamless adhesion between insulating barrier and telescopic insulating bar through seccotine; With abundant assurance insulating property, reduce self leakage current.
The utility model compared with prior art; Safe distance in the time of not only can effectively reaching the hot line job of defined in " electric power safety working regulation " between the person and electrified body mandatory requirement, the safe distance when ensureing operation has strengthened the safe and reliable coefficient of operating personnel's hot line job; Critical protection has been played in personal safety; Simultaneously, the length through regulating insulating bar and the distance of insulating barrier and hook, but the electrical quantity of the metal oxide arrester of live testing 35KV electric pressure not only; Can also satisfy the test of 110KV, 220KV lightning arrester, play the function of multi-use.
Description of drawings
Accompanying drawing is the structural representation sketch of the utility model.
Embodiment
Shown in accompanying drawing; Insulation tube 4 adopts the epoxy resin pipe to process; Be with telescopic insulating bar 3 in it, the length of scalable sounding rod, the telescopic insulating bar 3 of the internal lock may command of rotating insulated pipe 4 is not threaded off with insulation tube 4; To satisfy the surveying work of all kinds lightning arrester, have the hole that is used to assemble hook 2 apart from 70 millimeters places, insulation tube 4 ends; Telescopic insulating bar 3 adopts the epoxy resin pipe to process; For regulating insulating barrier 1 and the distance of linking up with 2; Have the mounting hole of 9 millimeters of 100 millimeters * Φ apart from 120 millimeters places, telescopic insulating bar 3 ends, the metal hanger 2 that is used for being connected with the lightning arrester base lead-in wire transmission of electric signals is contained in the hole of telescopic insulating bar, through the clearance fit of screw retention hook 2 and telescopic insulating bar 3; Guarantee that integral body does not occur becoming flexible landing; The end of telescopic insulating bar 3 is fixed with insulating barrier 1, and insulating barrier 1 adopts epoxide resin material to process, and it is shaped as long 365 millimeters * 255 millimeters ellipse; Realize the seamless adhesion of 3 of insulating barrier 1 and telescopic insulating bars fully guaranteeing insulating property through seccotine, reduce self leakage current; Through resistance test, under 220KV, do not occur puncturing, and insulating barrier 1 is carried out the Leakage Current test of the equal electric pressure of 35KV; The Leakage Current of metal hanger 2 is lower than 10 microamperes; Satisfy the safety current of human body fully, the utility model mainly is through the contact area between increase and the electrified body, the creepage distance when enlarging discharge.Safe distance when verifying the 35KV electric pressure hot line job of the utility model between the person and electrified body is greater than more than 0.6 meter; On the subsequent use lightning arrester base of 35KV, carry out safe distance test, through actual measurement, from the lightning arrester top to dividing plate 1; Again from the top of dividing plate 1 to hook 2; Its coverage can reach more than 0.7 meter, satisfies " State Grid Corporation of China's electric power safety working regulation (power transformation part) " regulation fully, can fully guarantee personal safety again.The utility model only needs to regulate telescopic insulating bar 3 and gets final product when carrying out the test of 110KV, 220KV lightning arrester electrical quantity.
