(one) Application
QJGZ-630/6 Mine-used Flameproof and I.S. High- voltage Vacuum Electromagnetic Starter is suitable for underground coal mines with explosive gases such as methane. It can control, protect and measure the high-voltage motor and electric devices frequently started in the 3-phase neutral-point ungrounded power supply system which is at 50 Hz, rated voltage 10 kV/6 kV rated current up to 630 A.
(two)Features
1.it is composed of an explosion-proof enclosure and functional core, making it convenient for maintenance.
2.The unique fast-open structure makes it easier to open and close.It is composed of an explosion-proof enclosure and functional core, making it convenient for maintenance.
 
 3.With an exclusive microcomputer protector for underground coal mines, it has protecting functions such as overload, short-circuit, directionalpower leakage, insulation fault, over or under voltage, and it also has fault self-diagnosis and inquiry functions4.  Three types of structure a, b, c are available so as to meet different demands of current-carrying, communication, feedback, or direct control.
5.  The switch can be switched on or off automatically or manually.
6.  The remote control signal is intrinsically safe.
7.  With the communication interface it enables networking with the communication and remote monitoring function.
