Normal mining explosion proof high-voltage vacuum switchgear

Introduction

KYGC28 handcart high-voltage vacuum switch cabinet is used as the switch device for the power distribution, starting, control, commutation, double-current switching and so on of such equipment as high-voltage fan and water pump, applicable for the 3-phase AC high-voltage power supply system with 12kV or 17.2kVrated voltage and 50Hz rated frequency.

Multiple solutions of fan switching

The switchgear can be realized by 3-service-position(rotate, isolate, reverse) high-voltage isolated switch; or by two sets of 5-pole vacuum contact commutator ; or by changing the plug of the handcart. The structure can also be used as the switch cabinet of double-power supply switching, like double-power supply high-voltage switch cabinet for winch.

As to the max allow start current ,load nature and engine types, Multiple modes for starting engine Such as starting modes as direct starting, reactor step down start, frequency sensitive rheostat start and one with X soft start and so on. Advanced and multi protection functions.

KYGC28 switch cabinet can be provided with protection of short circuit, overflow, leakage, under voltage in accordance with different applications. The protector adopts the traditional electromechanical relay, static multi-functional electronic relay or microcomputer automatic protector with remote control, measurement and communication for no-guard substation.
