Description
Technical field
The present invention relates to arrester checks technical field, particularly a kind of lightning arrester with electrical testing meter and arrester checks method.
Background technology
At present the lightning arrester in electric system generally adopts metal oxide arrester (MOA), and because long-term work is under high voltage, the superpotential of bearing is impacted a lot, valve block is aging make moist deteriorated very general.The Main Means that metal current Oxide Arrester detects has: the methods such as power failure preventive trial, total current on-line monitoring, total current and current in resistance property band electro-detection, infrared thermal imaging thermometric.Because power failure preventive trial generally can only detect when MOA installation or overhaul power failure, can not obtain in time the state of MOA; The application of total current on-line monitoring and infrared thermal imaging thermometric is subject to cost and accuracy limitation to apply wideless.So each electric company now, major part all adopts total current and current in resistance property live testing.
And the general detection methods such as total leakage current, resistive current first harmonics and third harmonic that adopt of existing instrument test method.Due to needs accurately voltage signal make reference measurement current in resistance property, at lightning arrester place line voltage distribution mutual inductor secondary terminals, accessing voltage signal is the highest method of current data reliability.
By testing equipment voltage circuit and be connected on tested phase bus PT secondary voltage terminal, can obtain the phase place of busbar voltage.Can directly get three-phase voltage, also desirable single-phase voltage is set to single-phase reference voltage in instrument internal.Current measurement line is pressed correct phase sequence and is connected, and with cable, connects main frame and isolator.PT gets reference voltage, and single-phase reference voltage connects isolator A (Huang) passage, three corresponding A (Huang) B (green) C (red) that connect.
This kind of method danger close, if the wrong clip of careless slightly folder gently burns out surveying instrument, heavy may touch terminal by mistake and cause operating voltage transformer (VT) short circuit, or the voltage signal loop decompression of protection causes that protection malfunction causes large area blackout.Because this test method has personal device security hidden danger, generally avoid using.And due to PT terminal box from lightning arrester sometimes away from, wiring is very inconvenient, only gets all the other two phase voltage actual phase of a phase voltage and disturbed by this phase electric field and skew occurs to convert rectification by instrument software setting.And the process of correcting will be brought inevitable systematic error, reduced accuracy of measurement.
And the tablet measuring method of development in recent years is used capacity plate antenna to measure electric field phase near lightning arrester bottom, the B phase electric field phase of usining carries out the differentiation of capacitance current and current in resistance property as reference phase, and tablet is very responsive to measuring position and angle, the electric field sensing is subject to the interference of A, C phase very large, conventionally shift position or angle just directly cause result severe overweight a little, and measuring error cannot meet testing requirements.And if tablet is lifted to such an extent that cross and closely busbar voltage can be caused to instrument causes casualties and device damage with electrified body.
Just how method of testing shields a great problem that interphase interference becomes lightning arrester live-line test both at home and abroad at present.
And if often to the lightning arrester inspection that has a power failure, can not find in time lightning arrester defect in use.And to spend a large amount of manpower and materials and unnecessary operation, when causing maintenance damage to electrical network, also can cause certain power failure economic loss.
