Product Description
Switchgear serves as an indispensable cornerstone in electrical systems, masterfully orchestrating the opening, closing, controlling, and protection of electrical equipment throughout power generation, transmission, distribution, and conversion stages. Its quintessential purpose is to uphold flawless operation and deliver comprehensive protection across a wide spectrum of power networks.
Structure
High voltage switchgear is intricately designed with distinct, sectionalized compartments like the busbar room, circuit breaker room, secondary control room (often called the instrument room), and feeder room. These compartments are meticulously isolated by steel partitions. For example, in the KYN28A-12 model, the instrument room is strategically positioned at the top, the circuit breaker room occupies the central area, and the cable room is stationed at the base.
Low voltage switchgear is systematically classified based on the installation technique of its components into fixed and drawer configurations. The drawer type switchgear boasts a sturdy fixed cabinet structure coupled with a highly adaptable movable device section, ensuring streamlined operations.
Internal Components
The vital internal components encompass circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a suite of cutting-edge protective devices, all precisely orchestrated to guarantee operational efficiency and stringent safety standards.
Classification
Switchgear is categorized by the installation method of the circuit breakers into movable and fixed variations. Cabinetry structures are further divided into open, metal-enclosed, or metal-enclosed armored types. Their voltage levels determine them as either high-voltage (surpassing AC1000V) or low-voltage (below AC1000V), and voltage waveform separates them into AC and DC. They fulfill specific roles as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and beyond.
Effect
Control Function: Masterfully manages circuit connectivity to enable the initiation and cessation of power equipment operations, ensuring precise control, optimal performance, and enhanced operational efficiency.
Protection Function: Delivers robust protection by automatically severing the circuit amidst overloads, short circuits, or leakage scenarios, thereby safeguarding equipment and personnel against any potential hazards.
Application Location
Perfect for implementation 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 reliability and performance across a multitude of environments.
