Mine Explosion-proof Reversible Electromagnetic Actuator
Mine Explosion-proof Reversible Electromagnetic Actuator
Applications
The actuator is mainly used for on-site stopping or remote control of the three-phase squirrelcage induction motor under the mine with explosive gases (methane) mixture in the AC circuit,with the frequency of 50Hz and voltage of 380V.
Features
1. Controlling mode: close control, remote control and sequential control;
2. It adopts electronic motor comprehensive protector, which has complete function, excellent performance and reliable operation as well as protection from voltage loss, overload, short circuit, overvoltage, phase failure and main circuit leakage lockout.
3. The electronic protector is suitable to adjustits rated working current according to the charge capacitance, to effectively protect the charge and circuit.
