Product Description
6kv Flameproo & Intrinsic Safety Vacuum Power Distribution Equipment
PJG9L-630/6
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 6kV, rated current up to 630A.
Features
This equipment is Program A designed by our company together with nationwide factories. Besides advantages of the same kind from home and abroad, it also combines further improvement and the latest technology.
Unique Fast-open structure makes it easier to open and close
Isolation panel is added, with interior illumination
It is composed of explosion-proof enclosure and functional core. Circuit breaker can be easily withdrawn from its space either for maintenance purposes or for replacement with a working one.
Exclusive protection for underground coal mines, such as double CPUs, digital computers and high-speed AIDS convertible IC, helps to protect the power system from damage of overload, earth leakage, insulation fault, short-circuit, wind power gas, and over or under voltage. Its strong anti-interference ability adapts itself to hazardous environment in coal mines. The drop-down menu of the LCD display gives detailed real-time information about the working environment and the humanized interface is convenient for operation and routine inspection.
Four types of structure a, b, c, d are available so as to meet different demands of current-carrying, communication, feedback, or direct control.
Spring energy storage type circuit breaker is used. It can be switched on or off automatically or manually.
Remote control signal is intrinsically safe.
RS485 interface is compatible with network and remote monitor device.
