Description

PBG*2

Mining Flameproof Vacuum Power Distribution Equipment

Functions:

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 6kV, rated current up to **0A.

Features:

It is updated from PGB*****0, with more reliable structure and function.

1. Advanced CPU is used to protect the power system from damage of overload, short-circuit, earth leakage, insulation fault, wind power gas, and over or under voltage. Also, self-inspection and inquiry functions are available.
2. Three types of structures a, b, c are available so as to meet different demands of current-carrying, communication, feedback, or direct control.
3. Circuit breaker can be switched on or off manually or automatically.
4. It is composed of several individual boxes, which are small in size and light in weight, and are easy to transport and maintain in underground coal mines.
5. It is explosion-proof between the wiring cavity and the power distribution cavity. A patent ***********3.0 has been applied for this structure.
