Product Description
A switchgear is a cornerstone piece of electrical equipment, indispensable for the smooth and efficient operation of power systems. It primarily serves the crucial purposes of opening, closing, controlling, and safeguarding electrical apparatus throughout the intricate processes of generation, transmission, distribution, and energy conversion.
Structure
High Voltage Switchgear: This state-of-the-art equipment generally includes a busbar room, circuit breaker room, secondary control room (also known as the instrument room), and feeder room. Each compartment is expertly isolated using durable steel plates. For example, the KYN28A-12 model is thoughtfully designed with the upper portion serving as the instrument room, the middle section as the circuit breaker room, and the lower part as the cable room, ensuring unmatched performance and safety.
Low Voltage Switchgear: Depending on the component installation method, it is categorized into fixed and drawer types. The innovative drawer type switchgear combines a stationary cabinet body with a dynamic, movable device part, delivering enhanced flexibility and efficiency.
Internal Components
The internal components are vital to the switchgear's performance, mainly comprising circuit breakers, isolating switches, load switches, operating mechanisms, transformers, along with a wide array of protective devices, ensuring dependable operation and unmatched safety.
Classification
This sophisticated equipment can be classified by various criteria. Based on circuit breaker installation methods, it is available in both movable and fixed types. The cabinet structure is available in open, metal enclosed, and metal enclosed armored configurations. Voltage levels define high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V). Further classification into AC and DC switchgear is determined by voltage waveform, each uniquely tailored for specific purposes like incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more.
Effect
Control Function: Masterfully engineered to connect and disconnect circuits, it enables precise start-stop control of power equipment, ensuring operational efficiency and unparalleled reliability.
Protection Function: Designed with safety in mind, this function automatically disconnects the circuit in the event of overload, short circuits, leakage, and other faults, thereby protecting both equipment and personnel from potential dangers.
Application Location
Crafted for versatile application, this switchgear is ideally suited for a myriad of environments, including power plants, substations, petrochemical industries, metallurgical steel rolling, light industry, textiles, factories, and mines, as well as residential areas and high-rise buildings, ensuring power reliability and safety across diverse and demanding settings.
