Product Description
The switchgear is a pivotal piece of electrical equipment, designed with precision to artfully open, close, control, and protect electrical devices. It plays an essential role during the dynamic processes of power generation, transmission, distribution, and energy conversion in modern power systems.
Structure
High voltage switchgear: This sophisticated configuration typically comprises a busbar room, circuit breaker room, secondary control room (instrument room), feeder room, and more, each meticulously isolated by durable steel plates. Take the KYN28A-12 model as an example: the upper section houses the instrument room, the middle section is dedicated to the circuit breaker room, and the lower section accommodates the cable room.
Low voltage switchgear: Categorized by component installation methods, it includes fixed and drawer types. The drawer type switchgear is ingeniously designed with a stable cabinet body and a movable device part, offering flexibility and ease of use.
Internal Components
The internal components are the heart of our switchgear, featuring cutting-edge circuit breakers, isolating switches, load switches, precise operating mechanisms, reliable transformers, and an array of advanced protective devices, ensuring optimal performance and safety.
Classification
Switchgear is classified by several criteria: By circuit breaker installation as movable and fixed types; By cabinet structure as open, metal enclosed, and metal enclosed armored types; By voltage levels into high-voltage (above AC1000V) and low-voltage (below AC1000V) switchgear; By voltage waveform into AC and DC switchgear; By purpose, it is divided into incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and much more.
Effect
Control Function: Our switchgear seamlessly connects and disconnects circuits to efficiently start and stop power equipment, maintaining a smooth operational flow.
Protection Function: The switchgear's advanced protection mechanism automatically cuts off circuits during overload, short circuit, leakage, and other faults, safeguarding both equipment and personnel with unparalleled reliability.
Application Location
Our high-performance switchgear is perfectly suited for an expansive range of settings, including power plants, substations, petrochemicals, metallurgical steel rolling, light industry textiles, factories, mines, residential areas, and high-rise buildings, expertly addressing diverse electrical needs.
