Product Description
A switchgear serves as the backbone of electrical management, predominantly engineered for the essential roles of opening, closing, controlling, and safeguarding electrical circuits. These systems are indispensable during the entire spectrum of power systems, encompassing generation, transmission, distribution, and energy conversion processes.
Structure
High voltage switchgear is a sophisticated assembly, typically comprising a busbar room, circuit breaker room, secondary control room (also known as the instrument room), feeder room, and more, with each compartment securely isolated by robust steel plates. For example, in the KYN28A-12 model, the upper segment houses the instrument room, the middle segment contains the circuit breaker room, and the lower segment is dedicated to the cable room.
Low voltage switchgear: This type is categorized into fixed and drawer types based on the installation styles of the components. Drawer type switchgear is ingeniously designed with a stationary cabinet and a versatile, movable device section.
Internal Components
The core components chiefly consist of circuit breakers, isolating switches, load switches, sophisticated operating mechanisms, transformers, and a wide range of protective devices, all working in harmony to ensure optimal performance.
Classification
Switchgear systems are meticulously categorized based on various criteria. By circuit breaker installation, they are either movable or fixed. The cabinet design can be open, metal-enclosed, or metal-enclosed armored. Voltage levels classify them into high-voltage (above AC1000V) and low-voltage (below AC1000V) categories. Further, based on voltage waveform, they are divided into AC switchgear and DC switchgear. Purpose-wise, they are segmented into incoming, outgoing, metering, and compensation cabinets.
Effect
Control Function: The switchgear deftly manages circuit connectivity, allowing for seamless start and stop control of power equipment, ensuring operational efficiency.
Protection Function: In the event of anomalies such as overloads, short circuits, or leakage faults, the switchgear instinctively interrupts the circuit, safeguarding both equipment and personnel from potential hazards.
Application Location
Ideally suited for a wide array of environments, including power plants, substations, petrochemical facilities, metallurgical steel operations, light industry textiles, factories, mines, residential areas, and high-rise edifices, ensuring unparalleled versatility and reliability.
