*0kV Mining Flameproof and intrinsic safety Vacuum Power Distribution Equipment (Permanent Magnetic Type)

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 *-phase neutral point ungrounded, with rated voltage *0kV and rated current up to **0A.

Features:

Besides all the features and advantages of spring energy storage type, it has its unique advantages, such as simple operation, high reliability, free for maintenance and long-life endurance.

1. It is magnet operated, permanent magnet held and intelligence controlled, more stable and endurable with obviously less components and no abrasion.
2. Horizontal fast-open structure makes it easier to open and close.
3. Exclusive protection for underground coal mines , such as double CPUS, DIGITAL COMPUTERS, digital control and high-speed AIDS convertible IC, helps to protect the power system from damage of overload, earth leakage, short-circuit, insulation fault, 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 easy for operation and routine inspection.
4. Four types of structure a, b, c, d are available so as to meet different demands of current-carrying, communication, feedback, or direct control.
5. Circuit breaker can be switched on or off manually or automatically.
6. Remote control signal is intrinsically safe.
7. RS**5 interface is compatible with network and remote monitor device.
