Description
Technical field
The utility model Electric Design technical field, particularly a kind of lightning arrester live-line test instrument.
Background technology
Superpotential, refer to the abnormal voltage rising that exceedes normal working voltage that electric system occurred under given conditions, according to the difference that produces principle, superpotential can be divided into the type such as lightning surge, switching overvoltage, because superpotential is greater than the normal working voltage that is even far longer than electric system, so may cause the damage of all kinds of power equipments in electric system.In electric system, often protect electrical equipment to avoid all kinds of superpotential impacts with lightning arrester, thereby lightning arrester is as a kind of protective device, the safe operation of itself just seems particularly important for the safe operation that ensures whole electric system.
The class lightning arrester being most widely used in electric system is at present referred to as Zinc-Oxide Arrester, Zinc-Oxide Arrester chief component is the zinc oxide valve plate of stack, this valve block will bear the effect of working voltage for a long time, thereby constantly there is leakage current to flow through, if Zinc-Oxide Arrester is in operation, generation is deteriorated, leakage current by zinc oxide valve plate will increase, make Zinc-Oxide Arrester heating seriously finally cause its thermal runaway and equipment breakdown occurs, so need to be by the situation of the leakage current of special instrument test Zinc-Oxide Arrester in service, judge its operation conditions, this under working voltage, the test that adopts special instrument to carry out all kinds of parameters of power equipment, be referred to as live testing.
Zinc-Oxide Arrester under working voltage is carried out to the live testing of leakage current, that its running status of monitoring is to ensure the important means of safe operation of power system, but there are following two comparison distinct issues in current drive method of testing: 1, connect take out stitches loaded down with trivial details, testing efficiency is lower, when live testing, need to access test lead at its lead-in wire place, discharge counter upper end, and discharge counter is conventionally liftoff higher, so need testing crew to scale a ladder to connect the work of taking out stitches, in real work, at least need the upper and lower ladder of testing crew just can complete the live testing work of single group Zinc-Oxide Arrester (comprising A/B/C three-phase) for 6 times.Longer when connecing disconnect mode and on the one hand can make testing efficiency compared with low consumption like this, on the one hand on ladder, ceaselessly can bring certain risk of dropping to testing crew up and down in addition, repeatedly move in addition ladder also relatively consumption test personnel's muscle power make testing crew quite tired out.2, charged connecing taken out stitches, there is personal electric shock risk, connecing when directly wearing insulating glove and test with staff taken out stitches, keep if do not note safe enough distance (be not directly contact electrification body just not can cause electric discharge, when voltage high to a certain degree time, the discharge range that enters electrified body just may cause electric discharge, so-called safe distance, refer to as preventing that people or object from too approaching the discharge minor increment of required maintenance of electrified body), the position that arm is stretched is too high, may cause high pressure once go between (electrified body) directly human body is discharged, cause serious human casualty accident.
