Product Description
Switchgear is a vital component in electrical systems, designed to expertly manage the opening, closing, controlling, and safeguarding of electrical apparatus during power generation, transmission, distribution, and conversion processes. Its primary role is to ensure seamless operation and protection across diverse power systems.
Structure
High voltage switchgear is meticulously 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 compartment is securely isolated with steel partitions. For instance, in the KYN28A-12 model, the instrument room occupies the upper section, the circuit breaker room is centrally positioned, and the cable room is located at the bottom.
Low voltage switchgear is categorized based on the component installation method into fixed and drawer types. The drawer type switchgear features a robust fixed cabinet body complemented by a versatile movable device section.
Internal Components
Key internal components include circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a range of advanced protective devices, all harmonized to ensure operational efficacy and safety.
Classification
Switchgear can be classified by the circuit breaker's installation method into movable and fixed types. Cabinet structures are categorized as open, metal enclosed, or metal enclosed armored. Voltage levels designate them as high-voltage (above AC1000V) or low-voltage (below AC1000V), while voltage waveform divides them into AC and DC. Additionally, they serve specific functions as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more.
Effect
Control Function: Expertly manages circuit connectivity to facilitate the start and stop operations of power equipment, ensuring precise control and optimal performance.
Protection Function: Provides robust protection by automatically disconnecting the circuit during overloads, short circuits, or leakage incidents, safeguarding both equipment and personnel from potential harm.
Application Location
Ideal for deployment in power plants, substations, petrochemical facilities, metallurgical and steel rolling operations, light industry textiles, manufacturing sectors, mining enterprises, residential complexes, and high-rise buildings, ensuring reliable performance across diverse environments.
