Surge arrester JCQ-3

The discharge counters, JS(Y)-5, 8, 10 , are connected in series to the surge arrester in the earth wire of surge arrester to record the surge arrester discharge times,and mainly composed of sample resistors, Silicon Bridge Rectifiers, high voltage capacitor, electromagnetic counter etc. It is the use of the discharge current through the arrester, the resistor voltage generated on-chip, and the silicon bridge rectifier to charge the capacitor, as the discharge electromagnetic counter, each counter is recorded once an electric discharge to achieve the number of operations recorded arrester. a, Used for the surge arresters of 220kV series and the below. b, The service condition is same as the surge arrester connected. c, It can’t be used in the serious pollution area and the fierce vibration place. a, The electrical performance has a greatly improvement with the use of the metal-oxide resistor. b, In the structure, the metal shell is made of stainless steel shell, which greatly increasing the resistance to aging and corrosion resistance, to overcome the shortcomings of the original glass-like friable. c, It is sealed with rubber gasket seal. d, High voltage terminal insulator isolated from the bottom center leads. e, It has the advantages of high sensitivity, counting accurate and reliable, clear display, compact structure, beautiful appearance, easy installation, reliable sealing and so on. f, The total weight of the counter is not less than 2.5kg. 5,The arrester monitor, which fully closed by metal case, is composed of two units, discharge count and leakage current measurement.
