Product Description
GKGR 3-in-1 HV vacuum soft starter cabinet
for mining (hereinafter referred to as soft starter cabinet) is signaled as “kA”,
applies to coal mining places of no hazards, gas, dusts, explosives and non-coal
mines places of an underground control room, an underground parking lot, main ventilation
duct, mechanical and electronic chamber. It also can be widely used in
aboveground places of large steel plant, petrochemical plant, sewage treatment
plant, power plant and so on.
A complete soft starter cabinet includes
power module, silicon controlled rectifier (SCR) module, motor protection
module, communication module and so on. The control core of a soft starter
cabinet is a microprocessor (CPU), which starts and protects the motor.
CPU controls SCR in conducting phase
trigger and control to lower the motor’s voltage and current, smoothly add the
motor torque until full speed operation. This way of start-up can lower the
motor’s start-up and impact current, reducing impacts on the power grid, motor
itself, and the mechanical influences connected from loads at the same time, in
order to prolong the device service life and reduce motor breakdowns.
Product Features:
1.e whole is composed of GKGR series HV solid soft starter device, circuit breaker, intelligent operation system, integrated microcomputer protector, bypass contactor.
2.Protection level of cabinet shell is 1P54;
3.The cabinet body is divided into four separate
rooms: busbar isolation room, relay room, circuit breaker handcart room, and
soft-start room.
