Product Description
A switchgear is an indispensable component within the realm of electrical equipment, playing a crucial role in the uninterrupted operation of power systems. It is fundamentally employed for the vital tasks of opening, closing, controlling, and safeguarding electrical apparatus across various stages—ranging from generation, transmission, distribution, to energy conversion—ensuring seamless functionality and protection.
Structure
High Voltage Switchgear: This state-of-the-art equipment is meticulously designed, comprising a busbar room, circuit breaker room, secondary control room (instrument room), and a feeder room. Each compartment is distinctly segregated using resilient steel plates to enhance safety and efficiency. Exemplified by the KYN28A-12 model, the sophisticated layout positions the instrument room at the top, the circuit breaker room centrally, and the cable room at the base, delivering exceptional performance and security.
Low Voltage Switchgear: Depending on the method of component installation, it is divided into fixed and drawer types. The innovative drawer type switchgear stands out with a stable cabinet body paired with a dynamic, movable device component, providing unmatched flexibility and operational efficiency.
Internal Components
The internal components are the backbone of the switchgear's functionality. They predominantly include circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a comprehensive array of protective devices, all working in harmony to assure consistent performance and utmost safety.
Classification
This expertly engineered equipment is categorized based on several criteria. It can be classified by the circuit breaker installation method into movable and fixed types. The cabinet configuration includes open, metal enclosed, and metal enclosed armored variations. Voltage levels further distinguish high-voltage switchgear (above AC1000V) from low-voltage switchgear (below AC1000V). Additionally, it is segmented into AC and DC switchgear based on the voltage waveform, each designed for specific applications such as incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets, providing tailored solutions for varied needs.
Effect
Control Function: With precision engineering, this function enables the adept connection and disconnection of circuits, facilitating precise start-stop control of power equipment, ensuring superior operational efficiency and unwavering reliability.
Protection Function: Designed with safety as a priority, this function automatically severs the circuit in the event of overload, short circuits, leakage, and other anomalies, thereby protecting both equipment and personnel from potential dangers.
Application Location
Engineered for adaptability, this switchgear is perfectly suited for a diverse range of environments, including power plants, substations, petrochemical industries, metallurgical steel rolling, light industry, textiles, factories, mines, as well as residential areas and high-rise structures, thereby ensuring dependable power distribution and safety across various contexts.
