Product Description
10kV Mining Flameproof and Intrinsic Safety Dual Power Vacuum Electromagnetic Starter
QBGZ-2X630/10
Function:
This product is used in underground coal mines, where there are mixed explosive gases, such as methane. It is used to control, protect and measure the power system, which is 3-phase neutral point ungrounded, with rated voltage 10kV, rated frequency 50hz, and rated current up to 630A.
Features:
This product is composed of explosion-proof enclosure and functional core and is easy for maintenance.
Advanced CPU protection helps to protect the power system from damage of overload, electric leakage, insulation fault, short-circuit, and over or under voltage. Error self-inspection and inquiry functions are also available.
Circuit breaker can be switched on or off manually or automatically.
Remote control signal is intrinsically safe.
RS485 interface is available.
Two high voltage vacuum contactors are mounted in the core. With different modes of wiring, it can be applied as:
One input with two output feeds. It can control and protect two motors simultaneously
Two inputs with one output feed. It can be used together with soft starter to achieve one-in-one-out, one-in-two-out, or one-in-three-out.
