Product Description
Switchgear is an indispensable element in sophisticated electrical systems, purposefully crafted to adeptly handle the intricate processes of opening, closing, controlling, and safeguarding electrical equipment throughout power generation, transmission, distribution, and conversion phases. Its core function is to guarantee flawless operation and provide unwavering protection across a broad spectrum of power networks.
Structure
High voltage switchgear is intricately engineered with well-defined compartments including the busbar room, circuit breaker room, secondary control room (known as the instrument room), and feeder room. These compartments are securely sectioned off with robust steel partitions. Take the KYN28A-12 model, for example: the instrument room is strategically placed at the top, the circuit breaker room is centrally located for optimal access, and the cable room resides at the bottom, ensuring efficient organization and functionality.
Low voltage switchgear is expertly categorized by the method of component installation into fixed and drawer types. The drawer type switchgear boasts a durable fixed cabinet structure enhanced by a flexible movable component section, offering a perfect blend of stability and versatility.
Internal Components
Crucial internal components encompass circuit breakers, isolating switches, load switches, sophisticated operating mechanisms, transformers, and a comprehensive suite of advanced protective devices, meticulously integrated to guarantee superior operational efficiency and safety.
Classification
Switchgear is meticulously classified by the installation method of the circuit breaker into movable and fixed types. The cabinet structures are distinguished as open, metal enclosed, or metal enclosed armored. They are further categorized by voltage levels as high-voltage (above AC1000V) or low-voltage (below AC1000V), and by voltage waveform into AC and DC. Additionally, they fulfill specific roles as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more, catering to diverse functional needs.
Effect
Control Function: Skillfully manages circuit interactions to facilitate the precise initiation and cessation of power equipment, ensuring unparalleled control and peak operational performance.
Protection Function: Delivers formidable protection by autonomously disengaging the circuit during overloads, short circuits, or leakage events, effectively shielding both equipment and personnel from possible hazards and ensuring safety.
Application Location
Perfectly suited for implementation in diverse environments such as power plants, substations, petrochemical facilities, metallurgical and steel rolling industries, light industry textiles, manufacturing sectors, mining enterprises, residential complexes, and towering high-rise buildings, ensuring steadfast reliability and performance.
