Product Description
A switchgear serves as a critical component of electrical infrastructure, meticulously crafted to manage the opening, closing, controlling, and safeguarding of electrical systems throughout power generation, transmission, distribution, and energy conversion. It ensures seamless and reliable operations, pivotal for the smooth functioning of power systems.
Structure
High voltage switchgear: This comprehensive system typically comprises a busbar room, circuit breaker room, secondary control room (also known as the instrument room), and feeder room. Each room is securely isolated by robust steel plates for enhanced safety. An exemplar model, like the KYN28A-12, features an upper instrument room, a middle circuit breaker room, and a lower cable room, meticulously organized for optimum efficiency.
Low voltage switchgear: Distinguished by its installation approach, it is available in both fixed and drawer configurations. The drawer type switchgear integrates a stationary cabinet with a flexible, movable device component, offering versatility and convenience.
Internal Components
The intricate assembly of internal components includes essential elements such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a variety of protective devices. These components collectively ensure robust performance and unwavering safety.
Classification
Switchgear is classified based on several criteria: Movable or fixed types according to circuit breaker installation; open, metal enclosed, or metal enclosed armored based on cabinet structure; high-voltage (above AC1000V) or low-voltage (below AC1000V) in terms of voltage levels; AC or DC depending on voltage waveform; and specific purposes such as incoming, outgoing, metering, and compensation cabinets, each tailored to targeted applications.
Effect
Control function: This function facilitates the seamless connection and disconnection of the circuit, enabling precise start and stop control over power equipment, thereby optimizing operational efficiency.
Protection function: In the event of circuit anomalies like overloads, short circuits, or leakages, the switchgear instantly disconnects the circuit, providing paramount protection for both equipment and personnel.
Application Location
This multifaceted switchgear is ideally suited for diverse environments including power plants, substations, petrochemical facilities, metallurgical and steel rolling operations, light industry textiles, a variety of factories and mines, residential zones, and towering high-rise buildings, ensuring comprehensive coverage and adaptability.
