Product Description
Switchgear forms the essential backbone of modern electrical systems, ingeniously crafted to masterfully handle the opening, closing, and controlling of electrical apparatus, while providing unyielding protection during all phases of power generation, transmission, distribution, and conversion. Its foremost function is to guarantee uninterrupted operation and ultimate protection across an array of sophisticated power systems.
Structure
High voltage switchgear is precision-engineered with thoughtfully designed compartments, including the busbar room, circuit breaker room, secondary control room, and feeder room, each uniquely positioned and securely partitioned with steel dividers. In particular, the KYN28A-12 model is innovatively arranged with the instrument room at the top, the circuit breaker room centrally located, and the cable room strategically placed at the bottom.
Low voltage switchgear is distinctively classified by the component installation method, falling into either fixed or drawer types. The drawer type switchgear boasts a sturdy fixed cabinet structure, enhanced by a dynamic and versatile movable device section, offering flexibility and reliability.
Internal Components
Among the vital internal components are state-of-the-art circuit breakers, isolating switches, load switches, precise operating mechanisms, transformers, and an array of advanced protective devices, all harmoniously orchestrated to deliver peak operational efficiency and uncompromising safety.
Classification
Switchgear is adeptly classified by the circuit breaker's installation method into either movable or fixed types. The sophisticated cabinet structures are further divided into open, metal enclosed, or metal enclosed armored categories. Additionally, voltage levels distinguish them as high-voltage (above AC1000V) or low-voltage (below AC1000V), and they can be segmented into AC and DC based on voltage waveform. Furthermore, they fulfill specialized roles as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, amongst others.
Effect
Control Function: Strategically manages circuit connectivity to expertly facilitate the seamless start and stop operations of power equipment, ensuring precise control and peak performance.
Protection Function: Offers unparalleled protection by automatically isolating the circuit in cases of overloads, short circuits, or leakage occurrences, effectively shielding both equipment and personnel from potential threats.
Application Location
Perfectly suited for deployment in a wide range of settings, including power plants, substations, petrochemical facilities, metallurgical and steel rolling operations, light industry textiles, diverse manufacturing sectors, mining enterprises, residential complexes, and high-rise buildings, ensuring consistent and dependable performance across varied environments.
