Product Description
Switchgear stands as the cornerstone of modern electrical systems, meticulously engineered to masterfully manage the crucial tasks of opening, closing, controlling, and safeguarding electrical components during the intricate processes of power generation, transmission, distribution, and conversion. Its paramount purpose is to assure seamless operation and uncompromising protection across an expansive array of power systems.
Structure
High voltage switchgear is crafted with precision, featuring distinct compartments expertly designed for optimal function, including the busbar room, circuit breaker room, secondary control room (instrument room), and feeder room. Each compartment is adeptly isolated with durable steel partitions. In the sophisticated KYN28A-12 model, the instrument room strategically occupies the upper section, with the circuit breaker room centrally placed, and the cable room efficiently stationed at the bottom.
Low voltage switchgear presents a refined categorization based on component installation methods, providing both fixed and drawer types. The drawer type switchgear boasts a sturdy, fixed cabinet structure, enhanced by a versatile and mobile device section for dynamic operation and maintenance.
Internal Components
Principal internal components encompass an array of vital elements, including circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and an assortment of advanced protective devices. These components are expertly harmonized to guarantee operational excellence and uncompromising safety.
Classification
Switchgear is categorized with precision based on the installation method of circuit breakers into movable and fixed variants. Their cabinet structures are classified as open, metal enclosed, or metal enclosed armored. Voltage classifications distinguish them as high-voltage (exceeding AC1000V) or low-voltage (below AC1000V), while the voltage waveform divides them into AC and DC types. They fulfill specific roles as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, among others.
Effect
Control Function: Proficiently manages the connectivity of circuits to effortlessly facilitate the initiation and cessation of power equipment operations, ensuring precise and optimal performance with authoritative control.
Protection Function: Delivers robust and reliable protection by autonomously disconnecting circuits amid overloads, short circuits, or leakage incidents, steadfastly safeguarding equipment and personnel from potential hazards.
Application Location
Perfectly suited for deployment across a spectrum of environments such as power plants, substations, petrochemical sites, metallurgical and steel rolling operations, light industry textiles, manufacturing sectors, mining enterprises, residential complexes, and towering high-rise buildings, ensuring dependable performance and reliability.
