Product Description
Switchgear stands as a cornerstone of electrical systems, crafted with precision to flawlessly govern the opening, closing, controlling, and safeguarding of electrical equipment. Whether it's during power generation, transmission, distribution, or conversion processes, this sophisticated gear ensures uninterrupted operation and protection across an array of power systems.
Structure
High voltage switchgear presents a meticulously engineered structure that features distinct compartments: the busbar room, circuit breaker room, secondary control room (also known as the instrument room), and the feeder room. Each compartment is fortified with steel partitions for enhanced safety. Take the KYN28A-12 model, for example, where the instrument room strategically resides at the top, the circuit breaker room commands the center, and the cable room is securely positioned at the bottom.
Low voltage switchgear is expertly classified by the component installation method, into innovative fixed and versatile drawer types. The drawer type switchgear boasts a solidly constructed, fixed cabinet body paired with a dynamic, movable device section for maximum flexibility and adaptability.
Internal Components
The core internal components are a synergy of circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a suite of advanced protective devices. Together, they create a harmonious system designed to deliver exceptional operational efficiency and unrivaled safety.
Classification
Switchgear is ingeniously categorized by the installation method of the circuit breaker into either movable or fixed types. Cabinet structures are further delineated as open, metal-enclosed, or metal-enclosed armored. Regarding voltage levels, they are distinguished as high-voltage (surpassing AC1000V) or low-voltage (under AC1000V), and by voltage waveform into AC and DC categories. Their specialized functions allow them to serve as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more, each tailored for specific operational purposes.
Effect
Control Function: Masterfully governs circuit connectivity to streamline the initiation and cessation of power equipment operations, ensuring accurate control and peak performance.
Protection Function: Delivers uncompromising protection by automatically severing the circuit in instances of overloads, short circuits, or leakage, thereby shielding both machinery and individuals from potential hazards.
Application Location
This switchgear is perfectly suited for implementation in power plants, substations, petrochemical facilities, metallurgical and steel rolling operations, light industry textiles, manufacturing sectors, mining enterprises, residential complexes, and towering skyscrapers, guaranteeing steadfast performance in a multitude of environments.
