Product Description
The switchgear is an essential piece of electrical equipment, meticulously designed for the pivotal tasks of opening, closing, controlling, and safeguarding electrical systems. It plays a crucial role during the power system's generation, transmission, distribution, and energy conversion phases.
Structure
High Voltage Switchgear: Typically composed of a busbar compartment, circuit breaker compartment, secondary control room (also known as the instrument room), feeder room, etc. Each section is meticulously isolated by sturdy steel plates. For example, the KYN28A-12 model boasts an upper instrument room, a central circuit breaker room, and a lower cable chamber.
Low Voltage Switchgear: Classified into fixed and drawer types based on the component installation method. The drawer-type switchgear features a static cabinet body combined with a dynamic, movable device section.
Internal Components
This includes a comprehensive array of components such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a range of protective devices, ensuring robust functionality and safety.
Classification
Switchgear is diversified by installation and structural characteristics: it includes movable and fixed types of circuit breakers; open, metal-enclosed, and metal-enclosed armored cabinet structures. It also spans high-voltage (above AC1000V) and low-voltage (below AC1000V) categories based on voltage levels. Furthermore, it encompasses AC and DC switchgear based on waveform, and is tailored by function into incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more.
Effect
Control Function: Expertly designed to connect and disconnect circuits, enabling seamless start and stop control of power equipment.
Protection Function: Instantly responds to circuit anomalies like overloads, short circuits, and leakages by automatically severing the circuit, thereby ensuring the utmost safety for both equipment and personnel.
Application Location
Perfectly suited for a variety of environments including power plants, substations, petrochemical facilities, metallurgical steel rolling mills, light industry textiles, factories, mines, residential areas, and high-rise buildings.
