Electrical Control Panel Board/power Distribution Cabinet/electrical Switchgear

electrical control panel board/power distribution cabinet/electrical switchgear

 

 

 

 

low voltage switchgear Divided into two types: drawer type and fixed type; Fixed type refers to fixed installation, while drawer type refers to the flexible assembly of certain electrical components into several functional units according to a certain circuit scheme, and then into a distribution panel (cabinet). Each functional unit is similar to a drawer, but it can be pulled out or UI like, so it is also called a pull-out type. Usually installed off the wall and can be maintained on both sides.

The functions of low-voltage switchgear are generally as follows:

1. Reasonably configure power supply;

2. When there is a fault in the circuit, it is beneficial to control the scope of the fault and facilitate the quick identification and elimination of the fault point;

3. Easy to arrange line maintenance in sections without the need for large-scale power outages;

4. Convenient placement of various protective devices inside the distribution cabinet (such as fuses to prevent short circuits, air switches to prevent overload, etc.);

 

In today's rapid development of complete power equipment, the safe and stable operation of low-voltage switchgear is crucial. With the complexity and depth of the power industry and application fields, the possibility of low-voltage switchgear malfunctions has also increased.

Typical problems that may occur in low-voltage switchgear include the inability of circuit breakers to close, the inability of the main switch in the incoming cabinet to open, the reversal or non rotation of the main metering reactive power, the inability of the drawer to rotate the meter, and the inability to automatically switch between dual power sources

 

The low-voltage draw out type switch cabinet is suitable for the power generation and supply system with three-phase AC frequency of 50Hz, rated working voltage of 380V and rated current of 4000A and below, which is used for power, distribution, motor centralized control and capacitance compensation. It is widely used in power plants, petroleum, chemical industry, metallurgy, textile, high-rise buildings and other places. The product conforms to iec60439, gb7251.1, JB / t9661 and other standards
