Product Description
A switchgear is a vital component of electrical equipment, meticulously designed for the crucial tasks of opening, closing, controlling, and safeguarding electrical apparatus during the dynamic processes of power generation, transmission, distribution, and energy conversion within power systems.
Structure
High Voltage Switchgear: This sophisticated assembly typically comprises a busbar room, circuit breaker room, secondary control room (also known as the instrument room), and a feeder room, each meticulously partitioned with steel plates to ensure safety and efficiency. In models like the KYN28A-12, the instrument room is strategically positioned at the upper part, the circuit breaker room occupies the middle section, while the cable room is secured at the lower section.
Low Voltage Switchgear: This comes in two distinctive styles based on component installation methods—fixed and drawer types. The drawer type switchgear is ingeniously designed with a stable, fixed cabinet body and a dynamic, movable device component, ensuring flexibility and ease of maintenance.
Internal Components
These integral components include circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and an array of protective devices, all engineered to ensure optimal performance and safety.
Classification
Switchgear Classification: Based on circuit breaker installation method, we distinguish between movable and fixed types; the cabinet structure allows for open, metal enclosed, and metal enclosed armored categories. By voltage levels, they are categorized into high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V). Voltage waveform differentiates them into AC and DC switchgear; purpose-based classification includes incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more.
Effect
Control Function: This function provides the capability to seamlessly connect and disconnect circuits, enabling precise start-stop control of power equipment, thereby ensuring operational efficiency and management.
Protection Function: With exceptional sensitivity, it proactively detects and responds to circuit anomalies such as overloads, short circuits, and leakages, promptly disconnecting the circuit to safeguard both equipment integrity and personnel safety.
Application Location
Ideal for diverse environments including power plants, substations, petrochemical facilities, metallurgical steel rolling operations, light industry textiles, various factories and mining operations, residential complexes, and towering high-rise buildings.
