Product Description
A switchgear is an indispensable component of electrical equipment, playing a pivotal role in ensuring the seamless and efficient operation of power systems. This essential apparatus is primarily employed to execute the crucial tasks of opening, closing, controlling, and defending electrical systems at every stage of power generation, transmission, distribution, and energy conversion, thereby guaranteeing uninterrupted and secure electrical service.
Structure
High Voltage Switchgear: This cutting-edge equipment typically includes a busbar room, circuit breaker room, secondary control room (instrument room), and feeder room, each compartment expertly isolated with reinforced steel plates. Specifically, the KYN28A-12 model is ingeniously configured with the top section serving as the instrument room, the middle section as the circuit breaker room, and the lower section as the cable room, all meticulously designed to deliver exceptional performance and safety.
Low Voltage Switchgear: Distinguished by its component installation method, it's categorized into fixed and drawer types. The innovative drawer-type switchgear features a stationary cabinet body paired with a dynamic, movable device component, offering remarkable flexibility and operational efficiency.
Internal Components
The internal components are the heartbeat of the switchgear, comprising primarily of circuit breakers, isolating switches, load switches, operating mechanisms, transformers, along with an extensive array of protective devices, all meticulously engineered to ensure dependable operation and uncompromised safety.
Classification
This highly sophisticated equipment is categorized based on various criteria. By circuit breaker installation method, it features both movable and fixed types. The cabinet structure is available in open, metal enclosed, and metal enclosed armored configurations. Voltage levels classify it into high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V). It is further divided into AC and DC switchgear based on voltage waveform, each meticulously tailored for specific applications such as incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets, among others.
Effect
Control Function: Ingeniously designed for precision, this function allows for the seamless connection and disconnection of circuits, enabling the accurate start-stop control of power equipment to ensure operational excellence and reliability.
Protection Function: Meticulously engineered with safety as a priority, this function automatically disconnects the circuit under conditions of overload, short circuits, leakage, and other faults, effectively safeguarding both equipment and personnel from potential hazards.
Application Location
Crafted for versatile application, this switchgear is ideally suited for an extensive range of environments, including power plants, substations, petrochemical industries, metallurgical steel rolling, light industry, textiles, factories, mines, residential areas, and high-rise buildings, ensuring dependable power reliability and safety across diverse settings.
