Current monitoring device Jcq-10

for leak detectionfor lightning arrestors

Jcq-10 type arrester monitor is a device which is connected in series under the arrester to detect the leakage current and record the action times of the arrester. It is used for zinc oxide arrester with voltage level of 500kV and below. The environmental conditions used are the same as the connected arrester. The arrester monitor features electromagnetic counting, current pointer indication and vibration resistance. structure and performance The monitor is mainly composed of valve plate, rectifier, capacitor, resistance, inductance, trigger circuit, protector, counting circuit, quantity of electromagnetic meter, magnetoelectric pointer ammeter, current measurement and conversion circuit, component and shell. Under normal use, the leakage current of arrester is directly displayed by magnetoelectric pointer instrument, and the pointer range is divided into two levels, 0-5ma and 0- 2mA automatic shift and light display, the indication range is divided into two gears, 0-5ma and 0-2ma automatic shift and light display, when the gear is 0-10mA, the light-emitting tube is on, when the arrester I acts, the electromagnetic counter accumulation technology, after the display is full, the automatic return to zero to continue the accumulation count, infinite cycle work, not clear zero!
