Wuxi high and low voltage switchgear is mainly electrical equipment based on circuit breakers in the working process; this means that the consumer manufacturer should connect the corresponding upper and lower piezoelectric equipment (including control equipment, maintenance equipment and measuring equipment) according to the requirements of the main electrical wiring diagram. Busbars, current-carrying conductors, insulators, etc. are assembled in closed or open metal cabinets as devices for receiving and distributing electrical energy in the power system.

Wuxi high and low voltage switchgear can also be called high voltage switchgear, which plays the role of switching, control or maintenance in the power generation, transmission, distribution, power conversion and consumption of the power system. Electrical products with voltage levels from 3.6kV to 550kV mainly include high-voltage circuit breakers, high-voltage isolating switches and grounding switches, high-voltage load switches, high-voltage automatic recloser and segmenters, high-voltage operating agencies, voltage explosion-proof distribution devices and high-voltage switch cabinets.


The high and low voltage switch cabinet has a wide body, large internal space, reasonable clearance and safety. It has the characteristics of installation, convenient maintenance and reliable operation. The main circuit diagram is complete and can meet the needs of various power and power distribution systems. It has five functions to avoid misoperation:

1. Avoid opening and closing switches with load.

2. Avoid wrong input charging distance.

3. Avoid accidentally opening and closing the circuit breaker.

4. Avoid hanging the ground wire when the power is on.

5. Avoid sealing with ground wire.


The components of high and low voltage switchgear are mainly composed of circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and various maintenance and installation. The main function of switchgear is to stop opening and closing, control and maintain electrical equipment in the process of stopping power generation, transmission, distribution and power conversion in the power system.

The structural characteristics of high and low voltage switchgear are as follows:

1. The whole cabinet adopts assembled combination structure, modular hole device, strong versatility, strong applicability and high degree of standardization.

2. The upper part of the cabinet is the busbar room, the front part is the electrical room, and the rear part is the cable entry and exit room. There are steel plates or insulating boards between each room to ensure safety.

3. The door of the drawer room of the MCC cabinet has a mechanical interlock with the operating handle of the circuit breaker or partition switch. The door can only be opened when the handle is in the broken position.

4. The power receiving switch, contact switch and drawer of the MCC cabinet are located in three positions: open position, experimental position and closed position.

5. According to the power demand, the top of the switch cabinet can be equipped with a bus bridge.
