Mine Explosion-Proof Type High-Voltage Vacuum Switch (KBG)

1. Function


This series mine explosion-proof type high-voltage vacuum distribution device is applicable
in underground coal mines with explosive and dangerous gas(methane) and coal dust, it is
equipped with BXB7-800/1440(660) mining explosion-proof type low-voltage protective box
and used on the high and low voltage side of dry type transformer for mine explosion-proof
type mobile substation, where it is used as high and low voltage distribution switch for
explosion-proof type mobile substation and protector to cut off the high-voltage power
supply when fault happens to low-voltage side of transformer.

2. Characteristics


2.1 Real-time English display for each kind of work data with simple and straightforward
parameter setting.
 
2.2 Standard RS485 communication interface.
 
2.3 Various kinds of protective functions for overload, short circuit, under voltage, over
voltage, loss of phase, electric leakage, three-phase imbalance etc.
 
2.4 It realizes cutting off power supply on high-voltage side for fault on low-voltage side by
being equipped with mine explosion-proof type low voltage protective box as mobile
substation.
