Mining Explosion-Proof Intrinsically Safe Permanent Magnetic Mechanism High Voltage Vacuum Distribution Device

The product is mainly applicable in the coal mine with explosive gas (methane mixture), to control, protect and measure in the three-phase AC neutral point not directly grounded power supply system of rated voltage 10KV, rated frequency 50Hz, rated current 630A. And can be used as a direct start high-voltage motor.


Product Details

The device adopts control and protection system composed of the programmable controller(PLC) and text display screen. There is a liquid crystal display window to show the operation status and various fault conditions of the protection box. The device with flexible parameter setting, stable quality, sensitive and reliable action performance, intuitive and concise operation and fault picture, has an intrinsically safe control interface, which is convenient for external control of equipment, and compose joint control.


The device has protection functions of insulation monitoring, high voltage leakage, overload, fault phase, undervoltage, short circuit, loss of voltage and overvoltage.
