Product Description
Switchgear is a vital piece of electrical equipment designed to manage the opening, closing, controlling, and safeguarding of electrical installations throughout the power system's lifecycle—from generation to transmission, distribution, and energy conversion.
Structure
High voltage switchgear typically encompasses distinct compartments such as the busbar room, circuit breaker room, secondary control room (also known as the instrument room), and feeder room, all separated by robust steel partitions. For instance, in the KYN28A-12 model, the top section houses the instrument room, the middle section contains the circuit breaker room, while the bottom section is reserved for the cable room.
Low voltage switchgear is categorized into fixed and drawer types based on how components are installed. The drawer type features a stationary cabinet body paired with a versatile, movable device section for enhanced adaptability.
Internal Components
Key components include circuit breakers, isolating switches, load switches, operational mechanisms, transformers, and an array of protective devices, all crucial for optimal functionality.
Classification
Switchgear is classified by circuit breaker installation as either movable or fixed. Cabinet structures are categorized into open, metal enclosed, and metal enclosed armored types. Voltage levels differentiate high-voltage switchgear (above AC1000V) from low-voltage switchgear (below AC1000V). Voltage waveform determines AC or DC switchgear classification. Purpose-driven categories include incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets.
Effect
Control Function: Enables seamless connection and disconnection of circuits, facilitating efficient start-stop control of power equipment.
Protection Function: Automatically severs circuits during overloads, short circuits, or leakages, ensuring the utmost safety for both equipment and personnel.
Application Location
Ideal for deployment in power plants, substations, petrochemical facilities, metallurgical steel rolling sites, light industry textile units, general factories, mining operations, residential complexes, and modern high-rise buildings.
