Product Description
A switchgear is an indispensable cornerstone of electrical infrastructure, crucial for the flawless operation of power systems. It serves the essential purposes of opening, closing, controlling, and protecting electrical devices, spanning the entire spectrum from generation to energy conversion, through transmission and distribution.
Structure
High Voltage Switchgear: This state-of-the-art equipment generally comprises a busbar chamber, circuit breaker compartment, secondary control zone (instrument chamber), and feeder bay. Each section is precisely segregated using durable steel barriers. For example, in the KYN28A-12 model, the configuration is ingeniously planned with the top section as the instrument chamber, the middle as the circuit breaker compartment, and the base as the cable chamber, ensuring peak performance and safety.
Low Voltage Switchgear: Depending on the installation type of its components, it is classified into fixed and drawer varieties. The cutting-edge drawer type switchgear boasts a stationary cabinet body paired with a flexible, movable component part, enhancing efficiency and adaptability.
Internal Components
The internal components form the backbone of the switchgear's functionality, primarily including circuit breakers, isolating switches, load switches, operating mechanisms, transformers, alongside a robust array of protective devices, ensuring steadfast operation and impenetrable safety.
Classification
This highly advanced equipment can be categorized by several criteria. Based on circuit breaker placement, it comes in movable and fixed variants. The cabinet structure presents open, metal enclosed, and metal enclosed armored types. Voltage levels distinguish high-voltage switchgear (exceeding AC1000V) from low-voltage switchgear (below AC1000V). Furthermore, it is segmented into AC and DC switchgear by voltage waveform, each meticulously crafted for specific applications like incoming panels, outgoing panels, metering panels, compensation panels, among others.
Effect
Control Function: Ingeniously crafted to connect and disconnect circuits, it enables precise start-stop control of power equipment, guaranteeing operational proficiency and steadfast reliability.
Protection Function: Designed with safety as a priority, this function automatically severs the circuit in events of overload, short circuits, leakage, and other faults, thereby shielding both equipment and personnel from potential dangers.
Application Location
Crafted for versatile use, this switchgear fits seamlessly into a diverse range of environments, such as power plants, substations, petrochemical sectors, metallurgical steel rolling, light industry, textiles, factories, mines, as well as residential zones and high-rise buildings, ensuring power dependability and safety in varied settings.
