Intrinsically safe reversible vacuum electromagnetic starter

Overview of intrinsic safety reversible vacuum electromagnetic starter

The Ann type reversible vacuum electromagnetic starter is suitable for use in the coal mine methane and explosive gas environment, the ac 50 hz, 660 v voltage, electric current for power supply line of the rating, the three-phase squirrel cage induction motor for direct or remote start, stop and forward and inversion of control, and the motor and the circuit overload, short circuit, open phase, under-voltage, overvoltage protection, as well as the load side leakage blocking protection circuit insulation condition of implementation.

Technical characteristics of intrinsic safety reversible vacuum electromagnetic starter

Adopt square shell quick open door, internal loop drawer type modular structure, maintenance is very convenient.

All Chinese LCD, menu operation, simple control operation, rich display information.

Microcomputer intelligent protection, using advanced 16-bit computer technology, all digital AC direct sampling, protection functions are complete, sensitive and reliable, high measurement accuracy.

Equipped with isolated RS485 serial remote control communication interface, supporting "four remote" function, easy access to the underground power grid integrated automation system.

The starter has overvoltage absorption device and short-circuit protection, overload protection, phase break protection/unbalanced protection, leakage lock \ under-voltage/over-voltage protection and perfect self-diagnosis function with fault memory query function
