Sell 6kV Mining Flameproof and Intrinsic Safety Vacuum AC Soft Starter

详情

This product is mainly used in underground coal mines, where there are mixed explosive gases, such as methane. It is used to control and protect the motors which are frequently started in the power system with rated voltage 6kV, and rated frequency *0hz and rated current up to **0A. 

It is functional and reliable and it helps to diminish the hit to the power system with soft start and soft stop. Remote control, close control and quick actuating closure are available.

1. Operation Principle: thyristors are connected in series and are micro-computer controlled so as to adjust the voltage gradually and smoothly. 
2. It is composed of explosion-proof shell and functional core. The silicon control rectifier and contactor can be drawn out for maintenance.
3. The front door is half quick-actuating closure type.
4. Its self-inspection function helps to protect the power system from the risk of over current, under current, short circuit, electric leakage, under voltage, over voltage, loss of phase, neutral grounding and etc.
