Product Description
Switchgear stands as a cornerstone in electrical systems, ingeniously crafted to deftly manage the intricate processes of power systems—ranging from generation and transmission to distribution and conversion. Its core purpose is to provide seamless operation and unwavering protection across a spectrum of power systems, ensuring reliability and efficiency at every stage.
Structure
Our high voltage switchgear boasts an exquisite structure, featuring meticulously designed compartments such as the busbar room, circuit breaker room, secondary control room (instrument room), and feeder room. These compartments are expertly isolated with robust steel partitions, offering unparalleled safety and organization. In the KYN28A-12 model, the upper section houses the instrument room, the circuit breaker room takes center stage, and the cable room resides at the base.
Low voltage switchgear is distinctively classified by the component installation method, available in both fixed and drawer types. The drawer type showcases a resilient fixed cabinet body, enhanced by a mobile device section for exceptional versatility and functionality.
Internal Components
The heart of our switchgear is its remarkable array of internal components, including circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a suite of advanced protective devices. These elements synergize to deliver exceptional operational efficiency and paramount safety.
Classification
Switchgear classification extends to the installation method of circuit breakers, available in both movable and fixed types. Cabinetry is further distinguished by structure—open, metal enclosed, or metal enclosed armored. Voltage levels define them as high-voltage (above AC1000V) or low-voltage (below AC1000V). Voltage waveform further divides them into AC and DC. They fulfill specific functions as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more, each tailored to precise operational needs.
Effect
Control Function: Our switchgear epitomizes expert control, seamlessly managing circuit connectivity to facilitate the start and stop operations of power equipment. This ensures precision control and peak performance in all scenarios.
Protection Function: It offers an impregnable layer of protection, automatically severing the circuit during overloads, short circuits, or leakage incidents, thus securing both invaluable equipment and human lives from unforeseen hazards.
Application Location
Our switchgear is the perfect choice for deployment across a myriad of environments. From power plants and substations to petrochemical facilities, metallurgical operations, light industry textiles, manufacturing sectors, mining enterprises, residential complexes, and towering high-rise buildings—it ensures unmatched reliability and performance across every locale.
