Product Description
Switchgear is an indispensable element in modern electrical systems. It is meticulously engineered to expertly oversee the operations of opening, closing, controlling, and safeguarding electrical equipment during the intricate phases of power generation, transmission, distribution, and conversion. The core purpose of this state-of-the-art apparatus is to ensure flawless operation and comprehensive protection across a multitude of power systems.
Structure
High voltage switchgear boasts a meticulously crafted structure, featuring discrete compartments such as the busbar room, circuit breaker room, secondary control room (also known as the instrument room), and feeder room. These compartments are securely isolated by robust steel partitions. For example, in the KYN28A-12 configuration, the instrument room is elegantly positioned at the top, the circuit breaker room is strategically placed in the center, and the cable room is thoughtfully situated at the bottom for optimal functionality.
Low voltage switchgear is expertly categorized by component installation methods into fixed and drawer types. The drawer type showcases a steadfast fixed cabinet body, ingeniously paired with a versatile movable device section, ensuring adaptability and robustness.
Internal Components
The essential internal components encompass circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a sophisticated array of advanced protective devices. These elements are perfectly orchestrated to guarantee operational excellence and uncompromising safety.
Classification
Switchgear can be astutely classified by the installation method of its circuit breaker into movable and fixed categories. Cabinet structures are further distinguished as open, metal enclosed, or metal enclosed armored. They are designated as high-voltage (above AC1000V) or low-voltage (below AC1000V) based on voltage levels, while their voltage waveform sorts them into AC and DC. Furthermore, they fulfill specific roles as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more, catering to a wide variety of applications.
Effect
Control Function: It masterfully manages circuit connectivity to enable the initiation and cessation of power equipment operations, ensuring precise control and optimal performance, enhancing efficiency and reliability.
Protection Function: Delivers exceptional protection by seamlessly disconnecting the circuit during occurrences of overloads, short circuits, or leakage incidents, thus safeguarding both valuable equipment and personnel from potential harm.
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. It ensures steadfast and reliable performance in a myriad of environments, meeting the demands of diverse applications with excellence.
