Product Description
A switchgear stands as a pivotal component in the realm of electrical equipment, indispensable for the flawless functioning of power systems. It plays a central role in the critical operations of opening, closing, controlling, and safeguarding electrical apparatus across the various stages of energy generation, transmission, distribution, and conversion.
Structure
High Voltage Switchgear: This cutting-edge equipment generally features a meticulously organized busbar room, circuit breaker room, secondary control room (instrument room), and feeder room. Each compartment is expertly segregated with durable steel plates. For instance, the KYN28A-12 model is ingeniously structured with the upper section as the instrument room, the central segment as the circuit breaker room, and the lower area as the cable room, ensuring peak functionality and safety.
Low Voltage Switchgear: Depending on the installation technique of its components, it is distinguished into fixed and drawer types. The breakthrough drawer type switchgear incorporates a stationary cabinet complemented by a flexible, movable device part, providing enhanced flexibility and operational efficiency.
Internal Components
The internal components are crucial to the switchgear's operation, predominantly comprising circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and an extensive range of protective devices, all of which guarantee dependable operation and heightened safety.
Classification
This advanced equipment can be categorized by various criteria. By circuit breaker installation, it is produced in movable and fixed types. The cabinet architecture allows for open, metal enclosed, and metal enclosed armored designs. Voltage levels differentiate high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V) classifications. It further divides into AC and DC switchgear based on voltage waveform, each tailored for specific applications like incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets, among others.
Effect
Control Function: Expertly crafted to manage the connection and disconnection of circuits, it facilitates precise start-stop control of power equipment, thereby ensuring enhanced operational efficiency and reliability.
Protection Function: Designed with safety at its core, this function automatically disconnects the circuit in the event of overload, short circuits, leakage, and other faults, thus protecting equipment and personnel from potential hazards.
Application Location
Engineered for broad application, this switchgear is ideally adaptable to a wide range of environments, including power plants, substations, petrochemical industries, metallurgical steel rolling, light industry, textiles, factories, and mines, as well as residential areas and high-rise buildings, ensuring power reliability and safety across a multitude of settings.
