Product Description
The switchgear, a crucial component of electrical systems, serves as the stalwart guardian of power systems. It is ingeniously designed for the pivotal tasks of opening, closing, controlling, and safeguarding electrical installations during vital processes of power generation, transmission, distribution, and energy conversion.
Structure
High Voltage Switchgear: This sophisticated setup typically comprises an array of distinct rooms like the busbar room, circuit breaker room, secondary control room (often referred to as the instrument room), and the feeder room, each meticulously separated by robust steel plates. Take the KYN28A-12 model for example; the upper echelon houses the instrument room, the central domain accommodates the circuit breaker room, while the foundation is occupied by the cable room.
Low Voltage Switchgear: Distinguished by its installation method, low voltage switchgear is categorized into fixed and drawer types. The drawer type is particularly noteworthy, featuring a steadfast cabinet body alongside a dynamic, movable device segment.
Internal Components
The heart of the switchgear is comprised of essential components such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a suite of protective devices, ensuring operational precision and safety.
Classification
Based on the circuit breaker's installation method, switchgear can be classified into movable and fixed types. When considering the cabinet's architecture, it can be categorized into open, metal-enclosed, and metal-enclosed armored varieties. By voltage, it is divided into high-voltage (above AC1000V) and low-voltage (below AC1000V) switchgear. Moreover, it is differentiated into AC and DC switchgear by voltage waveform, and by its purpose, it is segmented into incoming, outgoing, metering, and compensation cabinets.
Effect
Control Function: The switchgear adeptly connects and disconnects circuits, empowering it to control the start and stop functions of power equipment with precision and reliability.
Protection Function: In the event of an overload, short circuit, leakage, or other circuit anomalies, the switchgear automatically severs the circuit to safeguard both equipment and personnel, ensuring a secure operational environment.
Application Location
This versatile switchgear finds its place in a wide range of settings, from the bustling power plants and substations to the intricate world of petrochemicals, metallurgical steel rolling, and light industry textiles. It is indispensable in factories, mines, residential complexes, towering skyscrapers, and beyond.
