Product Description
A switchgear is an advanced electrical apparatus mainly utilized in the sophisticated processes of opening, closing, controlling, and safeguarding electrical systems. It plays a pivotal role during the generation, transmission, distribution, and conversion of energy within power systems.
Structure
High voltage switchgear: Typically comprises a busbar room, circuit breaker room, secondary control room (also known as the instrument room), feeder room, among others. Each compartment is thoughtfully segregated with steel partitions. For instance, in the KYN28A-12 model, the top section houses the instrument room, the middle section accommodates the circuit breaker room, while the lower section contains the cable room.
Low voltage switchgear: Categorized based on component installation as either fixed or drawer type. The drawer type switchgear is characterized by a sturdy fixed cabinet body paired with a dynamic movable device component.
Internal Components
These primarily consist of circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a variety of protective devices, each integral to the overall functionality.
Classification
Classification is based on numerous factors: installation method of the circuit breaker (movable and fixed types); cabinet structure (open, metal enclosed, and metal enclosed armored types); voltage levels (high-voltage switchgear above AC1000V and low-voltage switchgear below AC1000V); voltage waveform (AC switchgear and DC switchgear); and purpose (incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, etc.).
Effect
Control Function: It adeptly manages the connection and disconnection of circuits, enabling start-stop control of power equipment with precision.
Protection Function: In events of circuit anomalies such as overloads, short circuits, or leakages, it automatically disrupts the circuit flow, ensuring the utmost safety of equipment and personnel.
Application Location
This versatile switchgear is ideal for a multitude of locations, including power plants, substations, petrochemical sites, metallurgical steel rolling facilities, light industry textiles, factories, mines, residential areas, and high-rise buildings, delivering reliable performance.
