Product Description
A switchgear is a pivotal component in electrical engineering, expertly designed to manage the intricate processes of opening, closing, controlling, and safeguarding electrical systems during power generation, transmission, distribution, and energy conversion. This essential apparatus ensures the seamless operation and protection of power systems, contributing to their reliability and efficiency.
Structure
High Voltage Switchgear: This robust system is intricately structured with distinct compartments such as the busbar room, circuit breaker room, secondary control room (also known as the instrument room), and feeder room. Each of these is skillfully isolated with precision-engineered steel plates. In models like the exemplary KYN28A-12, the upper section houses the instrument room, the middle is dedicated to the circuit breaker room, and the lower section accommodates the cable room.
Low Voltage Switchgear: Ingeniously categorized into fixed and drawer types based on component installation methods. Specifically, drawer type switchgear comprises a fixed cabinet framework, complemented by a dynamic, movable device segment, ensuring adaptability and ease of maintenance.
Internal Components
This sophisticated system features an array of essential components, including circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a host of protective devices, all working in harmony to ensure optimal functionality and protection.
Classification
Switchgear is meticulously classified to suit various operational needs: By circuit breaker installation, it divides into movable and fixed types; based on cabinet design, it spans open, metal enclosed, and metal enclosed armored structures; according to voltage levels, it segments into high-voltage (above AC1000V) and low-voltage (below AC1000V); further categorized by voltage waveform into AC and DC switchgear; and by application into specialized cabinets such as incoming, outgoing, metering, and compensation cabinets.
Effect
Control Function: Expertly facilitates the seamless connection and disconnection of circuits to enable precise start-stop control of power equipment, ensuring optimal operational efficiency.
Protection Function: Proactively detects and responds to circuit anomalies such as overloads, short circuits, and leakage, automatically severing the circuit to safeguard both equipment and personnel, ensuring uncompromised safety.
Application Location
This versatile switchgear is ideal for deployment in a diverse array of settings, including power plants, substations, petrochemical facilities, metallurgical steel rolling operations, light industry textiles, factories, mining establishments, residential complexes, and high-rise buildings, effectively meeting the demands of varied industrial and residential environments.
