Product Description

A switchgear is an electrical equipment mainly used for opening, closing, controlling, and protecting electrical equipment during the generation, transmission, distribution, and energy conversion processes of power systems.
structure
High voltage switchgear: usually includes busbar room, circuit breaker room, secondary control room (instrument room), feeder room, etc., and each room is isolated with steel plates. Like KYN28A-12 model, the upper part is the instrument room, the middle part is the circuit breaker room, and the lower part is the cable room.

 

Low voltage switchgear: It is divided into fixed and drawer type according to the installation method of components. Drawer type switchgear consists of a fixed cabinet body and a movable device part.
Internal components
It mainly includes circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and various protective devices.
classification
According to the installation method of the circuit breaker, it can be divided into movable and fixed types; According to the cabinet structure, it can be divided into open, metal enclosed, and metal enclosed armored types; Divided into high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V) according to voltage levels; Divided into AC switchgear and DC switchgear according to voltage waveform; Divided by purpose into incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, etc.
effect
Control function: It can connect and disconnect the circuit to achieve start stop control of power equipment.

Protection function: When the circuit experiences overload, short circuit, leakage and other faults, it automatically cuts off the circuit to protect the safety of equipment and personnel.

Application location

Suitable for power plants, substations, petrochemicals, metallurgical steel rolling, light industry textiles, factories and mines, residential areas, high-rise buildings, etc.
