Product Description
A switchgear is a vital piece of electrical equipment, designed to expertly manage the opening, closing, control, and protection of electrical resources. It plays a crucial role in the generation, transmission, distribution, and the transformative energy processes within power systems.
Structure
High Voltage Switchgear: This intricate system usually comprises various rooms such as the busbar room, circuit breaker room, secondary control room (or instrument room), and feeder room. Each room is meticulously isolated with steel plates. In models like the KYN28A-12, the upper section houses the instrument room, the middle part features the circuit breaker room, and the lower segment contains the cable room.
Low Voltage Switchgear: Based on component installation methods, it is categorized into fixed and drawer types. The drawer type switchgear includes a fixed cabinet body complemented by a movable device part, ensuring flexible and efficient operations.
Internal Components
Key elements include circuit breakers, isolating switches, load switches, operating mechanisms, transformers, along with an array of robust protective devices. These components ensure optimal performance and safety in diverse operational conditions.
Classification
Switchgear Classification: Based on circuit breaker installation methods, they are classified into movable and fixed types. Cabinet structures can be open, metal-enclosed, or metal-enclosed armored. Voltage levels distinguish between high-voltage (above AC1000V) and low-voltage (below AC1000V) switchgears. According to voltage waveform, they are categorized into AC and DC switchgears. Functional divisions include incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets.
Effect
Control Function: It possesses the capability to proficiently connect and disconnect circuits, thereby achieving seamless start-stop control of power equipment, facilitating enhanced operational efficiency.
Protection Function: In the event of circuit overloads, short circuits, leakage, or other malfunctions, it ensures automatic disconnection to safeguard both equipment and personnel, enhancing overall safety and reliability.
Application Location
This state-of-the-art switchgear finds its application in a diverse range of settings, including power plants, substations, petrochemical industries, metallurgical steel rolling, light industries, textile sectors, various factories and mines, residential complexes, and towering high-rise buildings.
