Purpose

QBZ-120 (80) +315 / 1140 (660,380)BSF Mining Explosion Proof ventilator with Dual Power electrical atresia vacuum electromagnetic starter of explosive gases in the environment and coal dust in the mine, in the exchange of 50 HZ, voltage 1140 V and the following circuit to control three-phase squirrel cage induction motor, directly or remote start-stop. And wind power can be realized atresia, the Tornado aircraft control functions, as well as dual-function and power of the motor and related circuit protection.

Technical Data

1. Two independent power supplies and two independent explosion-proof chambers;while the other side normal working hours can be troubleshooting;

2. Fans with dual-supply, dual automatic switching function;

3. Starter with overload, short-circuit, breaking phase leakage atresia, less voltage, over-voltage protection, and other functions;

4. With the motor at all levels of power, operation, maintenance, flow, break phase, leakage, overload  display;

5. Protective function of gas, wind and electricity interlocking;
