Product Description
A switchgear is a vital component in electrical equipment primarily designed for opening, closing, controlling, and safeguarding electrical installations during the entire spectrum of power system operations: generation, transmission, distribution, and energy conversion.
Structure
High voltage switchgear typically comprises several sections: busbar room, circuit breaker room, secondary control room (or instrument room), and feeder room, each compartmentalized with sturdy steel partitions. For instance, in the KYN28A-12 model, the upper section houses the instrument room, the central section accommodates the circuit breaker room, and the base section contains the cable room.
Low voltage switchgear is categorized based on the installation method of its components into fixed or drawer types. The drawer type switchgear features a stable cabinet structure combined with a dynamic, movable device section.
Internal Components
The switchgear incorporates essential internal components such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a variety of protective devices, each crucial for optimal performance and safety.
Classification
Switchgear can be classified by installation and structural design: movable or fixed circuit breakers; open, metal enclosed, or metal enclosed armored cabinet structures. By voltage levels, they range from high-voltage switchgear (above AC1000V) to low-voltage switchgear (below AC1000V). Voltage waveform dictates AC or DC switchgear, and based on function, they are segmented into incoming, outgoing, metering, and compensation cabinets.
Effect
Control Function: This sophisticated equipment adeptly connects and disconnects circuits, facilitating precise start-stop control of power equipment, ensuring streamlined operations.
Protection Function: It intelligently intervenes during circuit anomalies such as overloads, short circuits, and leaks, automatically severing the circuit to safeguard both equipment and personnel from potential harm.
Application Location
Perfectly suited for diverse environments including power plants, substations, petrochemical sites, metallurgical and steel industries, light industry textile operations, factories, mines, residential complexes, and towering high-rise structures, ensuring versatile applicability and reliable performance.
