Mine Explosion-proof Vacuum Electromagnetic Actuator
Applications
The actuator is mainly used for direct or remote starting or stopping the three-phase squirrel-cage induction motor under the mine with explosive gases (methane) in the AC circuit, with the frequency of 50Hz, voltage of 660V, and current of 80A. Besides,
it’s also suitable for protection of the motor and relevant circuit.
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 adjust its rated working current according to the charge capacitance, to effectively protect the charge and circuit.
