Product Description
A switchgear is a vital component of electrical equipment, designed to efficiently open, close, control, and safeguard electrical systems during the power generation, transmission, distribution, and energy conversion processes. It is indispensable for ensuring the smooth and safe operation of power systems.
Structure
High Voltage Switchgear: This sophisticated system typically encompasses a busbar room, circuit breaker room, secondary control room (often referred to as the instrument room), feeder room, etc. Each compartment is meticulously isolated with robust steel plates. For instance, in the KYN28A-12 model, the upper section is designated as the instrument room, the middle section houses the circuit breaker room, and the lower section is reserved for the cable room.
Low Voltage Switchgear: Depending on the component installation method, it is categorized into fixed and drawer types. The drawer type switchgear features a stationary cabinet body paired with a dynamic device component, offering flexibility and ease of operation.
Internal Components
This includes crucial elements such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a variety of protective devices, all working in harmony to ensure optimal functionality and safety.
Classification
The classification of switchgear is diverse, offering versatility in application. Based on the circuit breaker's installation method, they are categorized into movable and fixed types. By cabinet structure, they are classified into open, metal enclosed, and metal enclosed armored types. Based on voltage levels, they are distinguished into high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V). Moreover, by voltage waveform, they are sorted into AC switchgear and DC switchgear. Lastly, by purpose, they serve as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more.
Effect
Control Function: This feature empowers the user to seamlessly connect and disconnect circuits, thereby enabling precise start-stop control of power equipment, ensuring efficient and reliable operation.
Protection Function: In the event of circuit anomalies such as overloads, short circuits, or leakages, the system automatically disconnects the circuit, thereby safeguarding both equipment and personnel, ensuring safety and reliability.
Application Location
The switchgear is adeptly suited for a wide range of locations, including power plants, substations, petrochemical industries, metallurgical steel rolling facilities, light industry textiles, factories, mining sites, residential areas, and high-rise buildings, ensuring universal applicability.
