Background technology
Lightning arrester can discharge thunder and lightning or hold concurrently to discharge power system operation superpotential energy, and protection electrical equipment endangers from instantaneous overvoltage, can block afterflow again, the unlikely electrical installation causing system earth short circuit.Lightning arrester is connected between live wire and ground usually, in parallel with protected equipment.When overvoltage value reaches the operation voltage of regulation, lightning arrester is action immediately, flows through electric charge, over-voltage amplitude, and proterctive equipment insulate; After magnitude of voltage is normal, lightning arrester restores to the original state rapidly again, to ensure system normal power supply.Modern high-pressure lightning arrester, not only for limiting because of the superpotential that thunder and lightning causes in electric system, also for limiting the superpotential because Dynamic System produces.
The effect of lightning arrester is used to protect the electrical equipment that in electric system, various electric equipment impacts from lightning surge, switching overvoltage, Frequency Transient Overvoltage and damages.It both can be used to protect atmospheric over-voltage, again can fence operation superpotential, and thus the protected equipment of Neng Shi transformer station exempts from the attack of lightning surge.When the lightning surge importing transformer station along circuit into exceedes protection of arrester level; first lightning arrester discharges; and by the introducing the earth of lightning current through conductor safety, utilize earthing device to make lightning voltage amplitude be limited in protected equipment lightning impulse below horizontal, make equipment protected.
The object of carrying out test of lightning arrester is, measures the Leakage Current of lightning arrester by test, by the analyzing and processing to Leakage Current, judges the making moist of lightning arrester, degree of aging and other situations about being damaged.
The defect existed in current test of lightning arrester and problem have:
1, the DC leakage test that does of lightning arrester, for high-voltage connection during warranty test and surrounding ensure enough safe distances, often needs to set up para tape in switch cubicle, keeps certain safe distance with the cabling and miscellaneous equipment that ensure high-voltage connection; In addition, when doing commissioning test, one is secondary to much organizing test of lightning arrester, often finishes one group and again will set up para tape, nigration equipment, so repeatedly, and the waste plenty of time;
2, staff often does a test of lightning arrester all needs to carry out a thread-changing, electric discharge, and bring a lot of inconvenience to staff, frequent operation also easily causes security incident;
3, usual, provisional object, as stone, tables and chairs etc., is widely used in this test, except can not ensureing fine ground connection, also easily occurs that lightning arrester falls down in process of the test, causes test to interrupt, there is potential safety hazard;
4, often there is the problem of horizontal plane in test of lightning arrester process, and existing stand can not carry out Level tune in use, makes test figure cause certain deviation, reduces the accuracy of this test.
