Product Description
Switchgear is a crucial powerhouse in electrical systems, masterfully orchestrating the opening, closing, control, and protection of electrical apparatus during the vital stages of power generation, transmission, distribution, and conversion. At its core, it ensures flawless operation and protection, seamlessly integrating into diverse power systems for maximum efficiency.
Structure
High voltage switchgear is elegantly designed with distinct compartments, including the busbar room, circuit breaker room, secondary control room (or instrument room), and feeder room. Each compartment is securely isolated by robust steel partitions. For example, in the KYN28A-12 model, the instrument room is strategically placed at the top, the circuit breaker room takes the central position, and the cable room resides at the bottom.
Low voltage switchgear is ingeniously categorized by the method of component installation into fixed and drawer types. The drawer type switchgear boasts a sturdy fixed cabinet body with a flexible, movable device section, offering adaptability and innovation.
Internal Components
The switchgear's key internal components are a symphony of crucial elements, including circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a suite of advanced protective devices, all working in harmony to ensure peak operational efficacy and heightened safety.
Classification
Switchgear is brilliantly classified by the circuit breaker's installation method into mobile and fixed types. Cabinet structures are categorized as open, metal enclosed, or metal enclosed armored. Voltage levels distinguish them as high-voltage (above AC1000V) or low-voltage (below AC1000V), with voltage waveform dividing them into AC and DC. They serve essential functions as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more, each tailored for specific roles.
Effect
Control Function: Impeccably manages circuit connectivity, facilitating the start and stop operations of power equipment with precision, ensuring optimal performance and control.
Protection Function: Delivers formidable protection by automatically disengaging the circuit during overloads, short circuits, or leakage scenarios, safeguarding equipment and personnel from potential hazards.
Application Location
Perfectly suited for deployment in power plants, substations, petrochemical facilities, metallurgical and steel rolling operations, light industry textiles, manufacturing sectors, mining enterprises, residential complexes, and high-rise buildings, ensuring steadfast performance across a multitude of environments.
