Product Description
A switchgear is an indispensable powerhouse of electrical equipment, primarily designed for the seamless opening, closing, controlling, and safeguarding of electrical systems. It operates with precision during the vital processes of power generation, transmission, distribution, and the conversion of energy within power systems.
Structure
High Voltage Switchgear: This robust category typically comprises several crucial rooms such as the busbar room, circuit breaker room, secondary control room (instrument room), and the feeder room. Ingeniously, each room is segregated using steel plates for enhanced safety. Taking the KYN28A-12 model as a prime example, the layout is thoughtfully organized with the instrument room strategically positioned at the top, the circuit breaker room centrally located, and the cable room placed at the bottom.
Low Voltage Switchgear: Distinguished by its installation method, it can be classified into fixed and drawer types. The drawer type switchgear is ingeniously constructed with a sturdy fixed cabinet body, complemented by a dynamic and movable device part, providing flexibility and efficiency.
Internal Components
The heart of the switchgear consists of integral components such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a comprehensive array of protective devices, all ensuring optimal performance and safety.
Classification
Switchgear Classification: Tailored to meet diverse needs, switchgear is classified in various ways. By installation, they are categorized into movable and fixed types. Based on cabinet structure, they can be open, metal enclosed, or metal enclosed armored. Voltage levels divide them into high-voltage (above AC1000V) and low-voltage (below AC1000V) switchgear. They further differ by voltage waveform into AC and DC switchgear. Purpose-based division includes incoming cabinets, outgoing cabinets, metering cabinets, and compensation cabinets, each crafted for specific functional needs.
Effect
Control Function: It boasts a powerful control function that allows for the meticulous connection and disconnection of circuits, enabling precise start-stop control of power equipment.
Protection Function: Equipped with unmatched protection capabilities, it autonomously disconnects circuits in events of overload, short circuits, leakage, and other malfunctions, safeguarding both equipment and personnel with utmost reliability.
Application Location
The Chaotai Switchgear finds its versatile application in diverse environments such as power plants, substations, petrochemicals, metallurgical steel rolling, light industry textiles, factories and mines, residential areas, and towering high-rise buildings, making it a universally trusted solution.
