Product Description
A switchgear is an essential electrical apparatus integral to the generation, transmission, distribution, and conversion of energy in power systems. It primarily serves the purpose of opening, closing, controlling, and safeguarding electrical equipment, ensuring smooth and efficient operations.
Structure
High Voltage Switchgear: Typically comprises distinct sections such as the busbar room, circuit breaker room, secondary control room (instrument room), and feeder room, each meticulously isolated by durable steel plates. In models like KYN28A-12, the upper segment is dedicated to the instrument room, the middle houses the circuit breaker room, and the cable room is strategically placed at the bottom.
Low Voltage Switchgear: Categorized into fixed and drawer types based on component installation techniques. The drawer-type switchgear features a stationary cabinet body paired with a movable device component, offering flexibility and efficiency.
Internal Components
Key components include circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a suite of protective devices, all designed to ensure optimal functionality and safety.
Classification
Switchgear is categorized by the installation method of circuit breakers into movable and fixed types; by cabinet structure into open, metal enclosed, and metal enclosed armored types. It distinguishes itself by voltage levels into high-voltage (above AC1000V) and low-voltage (below AC1000V) categories, and by voltage waveform into AC and DC switchgear. Additionally, it is classified by purpose into various cabinets such as incoming, outgoing, metering, and compensation cabinets.
Effect
Control Function: Empowers the connection and disconnection of circuits, facilitating the seamless start and stop control of power equipment, thereby enhancing operational efficiency.
Protection Function: In instances of overload, short circuit, leakage, and other electrical faults, it promptly severs the circuit to ensure the safety of equipment and personnel, providing a robust safeguard mechanism.
Application Location
Versatile in application, suitable for power plants, substations, petrochemicals, metallurgical steel rolling, light industry textiles, factories and mines, residential communities, skyscrapers, and a host of other locales demanding reliable power distribution solutions.
