Mining Explosion Proof and intrinsically safe Permanet magnet High Voltage Vaccum power Distribution Device

Purpose

Used in coal mine or underground where exists methane compound gases and dangerous explosive gases, plays the control and protect role in the circuit of AC50Hz, 10kV, 6kV rated voltage. 630A Rated current .Device has a, b, c, d four forms of structure in order to meet the usage modes such as closing circuit, contact, feeder, league table, direct control.

Features

Adopt micro-monitor integrated device, full Chinese backlit LCD display, real-time showing voltage, three phase current, etc;

The main breaking component use high-voltage vacuum permanent-magnetic circuit breaker;

With various protective functions: overload, short circuit, leakage, insulation monitoring, over-voltage, under-voltage, avoid-tripping (optional);

With electricity measurement function;

With reliable mechanical and electrical atresia , remote control tripping, emergency tripping devices to ensure safety;

Standard RS485 communication interface attached in KJ254 mining power monitoring system makes power distribution automatically, bringing about remote-measure, telecommunication, remote-control, remote regulate,

playing the function of remote opening and closing , long-distance meter reading to realize full automatically management.
