Mining Explosion Proof and intrinsically safe permanent magnetic High Voltage Vaccum Distribution Device

Purpose

Used in coal mine or underground where exists methane compound gases and dangerous explosive gases, plays the control, protect and measurement role under the 10kV,6kV rated voltage power source system whose three-phase AC point not earthing or earthing by Arc suppression coil with 50Hz rated frequency. Device adopt duel-circuit outlet, carry out double loop leakage and insulation monitoring protection, so that meet the require of multi-load.

Features

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

The main breaking component use VD4 made by ABB, high ability of breaking.

With various protective functions: overload, short circuit, leakage, insulation monitoring, over-voltage, under-voltage;

With stop skipping level trip function, avoid widespread power failure due to short circuit.

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