Product Description
A switchgear represents a crucial component in the realm of electrical equipment, pivotal for the flawless functionality of power system networks. This indispensable apparatus is primarily employed for its critical capabilities in opening, closing, controlling, and safeguarding the vital electrical infrastructure throughout various stages of generation, transmission, distribution, and energy conversion processes.
Structure
High Voltage Switchgear: This state-of-the-art equipment typically includes a busbar room, circuit breaker room, secondary control room (also known as the instrument room), and a feeder room. Each compartment is carefully isolated with durable steel plates to ensure maximum safety and efficiency. For example, the KYN28A-12 model is ingeniously structured with the upper section serving as the instrument room, the central area as the circuit breaker room, and the lower portion designated as the cable room, enhancing both performance and safety.
Low Voltage Switchgear: Depending on the method of component installation, it is categorized into fixed and drawer types. The versatile drawer type switchgear is designed with a static cabinet body and a dynamic, movable device part, providing flexibility and heightened efficiency.
Internal Components
The internal components are fundamental to the switchgear's operation, mainly comprising circuit breakers, isolating switches, load switches, operating mechanisms, transformers, along with an extensive array of protective devices, all working cohesively to ensure consistent reliability and superior safety.
Classification
This sophisticated equipment can be meticulously classified based on multiple criteria. According to circuit breaker installation method, types include movable and fixed. The cabinet structure options are open, metal enclosed, and metal enclosed armored. Voltage levels define it as high-voltage switchgear (above AC1000V) or low-voltage switchgear (below AC1000V). Additionally, based on voltage waveform, it is divided into AC and DC switchgear, each designed for specific applications such as incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, among others.
Effect
Control Function: Expertly crafted to connect and disconnect circuits, it enables precise start-stop control of power equipment, thereby enhancing operational efficiency and reliability.
Protection Function: Meticulously engineered for safety, this function automatically disengages the circuit during overload, short circuits, leakage, and other malfunctions, thereby protecting both equipment and personnel from potential hazards.
Application Location
Designed for broad applicability, this switchgear excels across a diverse range of environments, including power plants, substations, petrochemical sectors, metallurgical steel rolling, light industry, textiles, factories, and mines, as well as residential districts and high-rise buildings, ensuring consistent power reliability and safety across various settings.
