Product Description
A switchgear stands as a cornerstone of electrical equipment, pivotal in ensuring the flawless operation of power systems. It serves the crucial roles of opening, closing, controlling, and safeguarding electrical apparatus throughout the complex processes of generation, transmission, distribution, and energy conversion. This indispensable equipment fortifies the backbone of modern power infrastructure.
Structure
High Voltage Switchgear: This cutting-edge equipment is typically comprised of a busbar room, circuit breaker room, secondary control room (instrument room), and feeder room. Each compartment is meticulously isolated with strong steel plates. For example, in the KYN28A-12 model, the layout is ingeniously designed with the upper segment allocated to the instrument room, the center as the circuit breaker room, and the lower section as the cable room, ensuring peak performance and uncompromised safety.
Low Voltage Switchgear: Depending on the installation method of its components, it is categorized into fixed and drawer types. The revolutionary drawer type switchgear boasts a stationary cabinet body enhanced by a dynamic, movable device part, offering unmatched flexibility and operational efficiency.
Internal Components
The internal components are paramount to the switchgear's functionality, comprising mainly of circuit breakers, isolating switches, load switches, operation mechanisms, transformers, and a broad range of protective devices, collectively ensuring dependable operation and safety.
Classification
This sophisticated equipment is classified based on various criteria. By circuit breaker installation method, it comes in movable and fixed types. The cabinet structure offers open, metal enclosed, and metal enclosed armored configurations. Voltage levels determine high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V) classifications. Further division is based on the voltage waveform into AC and DC switchgear, each tailored for specific uses like incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets, among others.
Effect
Control Function: Meticulously designed, this function connects and disconnects circuits, facilitating precise start-stop control of power equipment, thereby ensuring operational efficiency and reliability.
Protection Function: Crafted with a focus on safety, this function automatically disconnects the circuit in cases of overload, short circuits, leakage, and other faults, thereby protecting both equipment and personnel from potential hazards.
Application Location
Designed for versatile applications, this switchgear is perfectly suited for a vast range of environments. Whether in power plants, substations, petrochemical industries, metallurgical steel rolling, light industries, textiles, factories, mines, or residential areas and high-rise buildings, it ensures power reliability and safety across diverse settings, solidifying its place as a critical component in modern electrical infrastructure.
