Product Description
A switchgear is a critical piece of electrical equipment integral to the seamless operation of power systems. It is primarily utilized for efficiently opening, closing, controlling, and safeguarding electrical apparatus during the essential processes of power generation, transmission, distribution, and energy conversion.
Structure
High Voltage Switchgear: Typically comprises distinct compartments such as the busbar room, circuit breaker room, secondary control room (instrument room), and feeder room, each meticulously isolated with robust steel plates. Take, for instance, the KYN28A-12 model, where the upper segment is reserved for the instrument room, the mid-section houses the circuit breaker room, and the lower portion contains the cable room.
Low Voltage Switchgear: Classified into fixed and drawer types based on the installation technique of its components. The drawer type switchgear features a stationary cabinet framework accompanied by a versatile, movable device section.
Internal Components
The switchgear mainly incorporates essential components such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a variety of protective devices, ensuring optimal functionality and safety.
Classification
Classification of switchgear is diverse: By installation method of circuit breakers, they are categorized into movable and fixed types; By cabinet structure, differentiated into open, metal enclosed, and metal enclosed armored types; By voltage levels, classified into high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V); By voltage waveform, divided into AC switchgear and DC switchgear; By purpose, categorized into incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, among others.
Effect
Control Function: This function is pivotal, allowing for the seamless connection and disconnection of circuits, thereby enabling precise start-stop control of power equipment, ensuring operational efficiency.
Protection Function: When the circuit is subjected to overload, short circuit, leakage, or other faults, the system automatically interrupts the circuit, thereby safeguarding both equipment and personnel from potential hazards.
Application Location
The switchgear is ideal for a wide array of environments, including power plants, substations, petrochemical facilities, metallurgical steel rolling operations, light industry textiles, factories, mines, residential areas, and high-rise buildings, providing reliable and safe electrical distribution solutions.
