Product Description
A switchgear is a vital component in electrical systems, primarily designed to manage the seamless opening, closing, controlling, and safeguarding of electrical equipment. It plays a crucial role during the power generation, transmission, distribution, and energy conversion processes within power systems, ensuring efficiency and safety at every stage.
Structure
High Voltage Switchgear: These sophisticated units typically consist of a busbar room, circuit breaker room, secondary control room (instrument room), feeder room, and more, each section carefully isolated with robust steel plates. For example, the KYN28A-12 model is ingeniously designed with its upper section dedicated to the instrument room, the middle for the circuit breaker room, and the lower section for the cable room.
Low Voltage Switchgear: Depending on the installation method, these are categorized into fixed and drawer types. The drawer-type switchgear features a stable cabinet body paired with a dynamic, movable device component, offering versatility and ease of maintenance.
Internal Components
This powerhouse of technology includes critical components such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a variety of protective devices, each engineered for optimal performance and safety.
Classification
Switchgear Classification: Depending on the circuit breaker's installation method, it is categorized into movable and fixed types. Based on the cabinet's structure, classifications include open, metal enclosed, and metal enclosed armored types. They are further divided by voltage levels into high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V), and by voltage waveform into AC and DC switchgear. Lastly, by their purpose, they transform into incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, etc.
Effect
Control Function: The switchgear efficiently manages the connection and disconnection of circuits, enabling precise start-stop control of power equipment, thereby enhancing operational efficiency.
Protection Function: In the event of circuit overload, short circuits, leakage, or other malfunctions, the switchgear promptly and automatically interrupts the circuit, safeguarding both equipment and personnel from potential hazards.
Application Location
The Kyn28-12 10kv Hv Switchgear Cabinet is exceptionally suited for diverse environments including power plants, substations, petrochemical facilities, metallurgical steel rolling mills, light industry textiles, various factories and mines, residential complexes, and high-rise buildings, providing unmatched reliability and performance.
