Product Description
A switchgear is a pivotal piece of electrical equipment, expertly designed for the precise operation of opening, closing, controlling, and safeguarding electrical devices. It plays an essential role during the various phases of power systems, including generation, transmission, distribution, and energy transformation.
Structure
High Voltage Switchgear: These robust systems typically encompass a busbar room, circuit breaker room, secondary control room (or instrument room), and a feeder room. Each section is meticulously isolated with steel plates to ensure optimal performance and security. Take for example, the KYN28A-12 model, where the upper section houses the instrument room, the center is dedicated to the circuit breaker room, and the base accommodates the cable room.
Low Voltage Switchgear: Depending on the installation method of components, it is classified into fixed and drawer types. The drawer type switchgear boasts a stable cabinet body alongside a flexible, movable device part, offering versatility and adaptability.
Internal Components
The intricate internal assembly primarily includes circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and an array of protective devices, all working in harmony to deliver seamless operations.
Classification
The classification of switchgear is multi-faceted: By circuit breaker installation method, they are either movable or fixed; By cabinet structure, they are categorized as open, metal enclosed, or metal enclosed armored types. Voltage levels distinguish them into high-voltage (above AC1000V) and low-voltage (below AC1000V) switchgear. Furthermore, they are categorized by voltage waveform into AC and DC switchgear, and by purpose into incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets.
Effect
Control Function: This sophisticated system expertly connects and disconnects circuits, enabling precise start-stop control of power equipment, ensuring efficient operation.
Protection Function: In the event of circuit complications such as overload, short circuit, or leakage, the system automatically severs the circuit, thereby safeguarding equipment and personnel from potential hazards.
Application Location
This versatile switchgear is ideally suited for a multitude of settings including power plants, substations, petrochemical industries, metallurgical steel rolling facilities, light industry textile factories, mines, residential areas, and high-rise buildings, ensuring reliable and safe power management.
