Product Desciption
1. Function
This mine explosion-proof type vacuum feeder switch is mainly used as main switch or
Branch switch in AC 50Hz power distribution system of indirect neutral-point earthing with
Voltage of 1140V or 660V and current of 400A or 200A in underground coal mines with
Explosive and dangerous gas(methane) and coal dust and it is also used for non-frequent
Start of big capacity motor.
2. Characteristics
2.1 Blue screen real-time English display for parameters like voltage, current, insulating
Value and switching-on times etc.
2.2 Standard RS485/232 communication interface.
2.3 Multiple Protective functions for overload, short circuit, loss of phase, electric leakage,
Leakage lockout, over voltage, under voltage etc.
2.4 Function of fan and power supply lockout, gas lockout, high-voltage electric interlock
