Product Description
A switchgear is a vital piece of electrical equipment, playing a crucial role in the power system. It is primarily utilized for the opening, closing, controlling, and safeguarding of electrical equipment throughout the stages of power generation, transmission, distribution, and energy conversion.
Structure
High Voltage Switchgear: This sophisticated equipment generally comprises a busbar room, circuit breaker room, secondary control room (instrument room), and feeder room, each meticulously isolated with robust steel plates. In models like the KYN28A-12, the upper section is dedicated to the instrument room, the central area houses the circuit breaker, and the lower segment is reserved for the cable room.
Low Voltage Switchgear: Featuring versatile installation methods, it is categorized into fixed and drawer types. The drawer type switchgear is designed with a sturdy fixed cabinet and a flexible movable device component, ensuring seamless operation and accessibility.
Internal Components
The switchgear's internal composition is predominantly comprised of essential elements such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, along with a variety of protective devices, each contributing to its optimal performance.
Classification
Depending on the installation method of the circuit breaker, switchgear can be classified into movable and fixed types. Based on cabinet structure, it is categorized as open, metal enclosed, or metal enclosed armored. Voltage levels classify it into high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V). Additionally, it can be divided into AC and DC switchgear according to the voltage waveform, and by purpose, into incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more.
Effect
Control Function: It features the capability to effectively connect and disconnect circuits, enabling precise start and stop control over power equipment.
Protection Function: In scenarios of circuit overload, short circuit, leakage, or other faults, the switchgear automatically disconnects the circuit, thereby ensuring the safety and protection of both equipment and personnel.
Application Location
This versatile switchgear is ideally suited for a diverse range of applications, including power plants, substations, petrochemical facilities, metallurgical and steel rolling industries, light industry textiles, factories, mines, residential areas, and high-rise buildings, offering unparalleled reliability and performance.
