QJZ-30, 60/660 (380) this series mining explosion-proof and intrinsically safe vacuum electromagnetic starter for containing explosive gas and coal.

Introduction:

QJZ-30, 60/660 (380) this series mining explosion-proof and intrinsically safe vacuum electromagnetic starter for containing explosive gas and coal mine, it is mainly used for the ac 50 hz, 660 v voltage (380 v) of the circuit, the control of flameproof three-phase asynchronous motor can realize direct start, stop, and may carry out phase during downtime.

The starting apparatus has overload, open phase protection functions such as locking, leakage and to display, can be local or remote control, and water level automatic control can be realized (water level to the on-line automatic open, water level to logoff automatically stop), can realize the function be unmanned.

Feature:

1 starter equipment overload, short circuit, leakage, phase locking and loss of pressure protection.

2. The starting apparatus has remote control function () in the circuit design.

3. The starter can match liquid level automatic controller () in the circuit design.

Through the upper and lower liquid level detection electrode, realizes the automatic control level of requirements.
