The Counter of Surge Arrester

The arrester is uses for with the electric discharge counter to monitor the arrester electric discharge movement one kind of high-pressured electric appliance, its structure by the non-ohmic resistor, the electromagnetic counter and some electronic component is composed. Under the normal operation voltage, winds through the counter to leak the electric current to be small, the counter does not act. When arrester through thunder electric wave, operation wave and power frequency overvoltage, the formidable operating current passes from the counter non-ohmic resistor, undergoes the direct-current transformation, causes the counter to the magnet coil electric discharge to operate one time, realizes the survey arrester movement number of times installment. Uses the band resistance in the structure to take the pressure, the magnet coil movement, the counter demonstrated that the transparent coverglass, seals the rubber gasket, negative and the flange and so on carries on the card to install the seal, the high pressure leaves the terminal to draw out from the ledger wall center. <DNT> The JS-8 electric discharge counter uses the SiC band resistance, is suitable in 5kV system 35kV and the following voltage class arrester. <DNT> The JSY-10/600 zinc oxide arrester special-purpose electric discharge counter uses the ZnO band resistance, is suitable in 5~10KV system 220kV and the following rank zinc oxide arrester, and may be suitable for the arrester the online examination
