Product Description
A switchgear is an essential component of electrical systems, meticulously designed for the seamless operation of opening, closing, controlling, and safeguarding electrical equipment during various phases of power systems such as generation, transmission, distribution, and energy conversion.
Structure
High-voltage switchgear: Typically composed of distinct sections including busbar room, circuit breaker room, secondary control room (instrument room), and feeder room, each meticulously compartmentalized by robust steel plates. The KYN28A-12 model, for instance, features an upper instrument room, a central circuit breaker room, and a lower cable room, ensuring precise and efficient management of high-voltage applications.
Low-voltage switchgear: This type is categorized based on installation methods into fixed and drawer types. The innovative drawer type switchgear includes a steadfast cabinet body complemented by a dynamic movable device, ensuring flexibility and reliability in various applications.
Internal Components
Key internal components encompass circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a diverse array of protective devices, all working in harmony to ensure optimal performance and safety.
Classification
Switchgear classification is multifaceted: Based on the circuit breaker's installation approach, it is categorized into movable and fixed types. The cabinet structure allows for open, metal enclosed, and metal enclosed armored types. Voltage levels distinguish between high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V). Voltage waveform divides them into AC and DC switchgear. Furthermore, they are tailored by purpose into incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more.
Effect
Control function: The switchgear excels in connecting and disconnecting circuits, facilitating precise start-stop control of power equipment, thereby enhancing operational efficiency and control.
Protection function: In instances of circuit anomalies such as overload, short circuit, or leakage, it acts swiftly to automatically disconnect the circuit, safeguarding both equipment and personnel from potential harm.
Application Location
This versatile switchgear is ideal for use in diverse environments, including power plants, substations, petrochemical facilities, metallurgical and steel rolling operations, light industry textiles, factories, mines, residential areas, and high-rise buildings, offering unparalleled reliability and performance in each setting.
