Mining explosion-proof intrinsically safe intelligent vacuum electromagnetic starter
Mining explosion-proof intrinsically safe intelligent vacuum electromagnetic starter
The explosion-proof electromagnetic starteris used in coal mines containing explosive gas (methane) and coal dust. It is suitable for the circuit of AC 50Hz, voltage 660V or 1140V, ungrounded three- phase center. Our Mining Reversible Electromagnetic Startercan carry out real-time monitoring and fault handling of the operating status through high-performance microcomputer, achieving mutual switch operation. It is 3-Loop vacuum electromagnetic starter.To local control or remote control the start and stop of three-phase asynchronous motor, and can be reversed at the stop.
Quick opening structure for this vacuum electromagnetic starter
•With local control and intrinsically safe remote control function
•With automatic water level control function, automatically control the start and stop of water pump according to the water level
•With menu operation structure, large LCD screen display, fault inquiry, fault recording and corresponding fault alarm information, and can record the specific time when the fault occurs
With RS485 communication function, remote monitoring and control can be conveniently realized
