Product Description
A switchgear is a pivotal electrical apparatus primarily employed for the efficient opening, closing, management, and safeguarding of electrical systems. It plays a critical role in the generation, transmission, distribution, and energy conversion phases of power systems, ensuring seamless and secure operations.
Structure
High Voltage Switchgear: Typically composed of distinct sections including the busbar room, circuit breaker room, secondary control room (also known as the instrument room), and feeder room, each meticulously partitioned with robust steel plates. Take for instance the KYN28A-12 model: its upper tier houses the instrument room, the central area is dedicated to the circuit breaker room, while the base accommodates the cable room.
Low Voltage Switchgear: Categorized based on component installation methods into fixed and drawer types. The drawer type switchgear features a stationary cabinet structure complemented by a mobile device component, offering flexibility and adaptability.
Internal Components
Integral components include circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a suite of protective devices, all working in harmony to ensure optimal performance and safety.
Classification
Switchgears are meticulously classified based on several criteria: By circuit breaker installation method, they are divided into movable and fixed types. Cabinet structure further classifies them into open, metal enclosed, and metal enclosed armored types. Depending on voltage levels, they are split into high-voltage switchgear (above AC1000V) and low-voltage switchgear (below AC1000V). Voltage waveform delineates them into AC and DC switchgear. Lastly, by purpose, they are segmented into incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more, each serving a specific function.
Effect
Control Function: This feature allows for seamless connection and disconnection of circuits, facilitating the start-stop control of power equipment with precision and reliability.
Protection Function: Equipped with advanced safety mechanisms that automatically sever the circuit amidst overloads, short circuits, and leakage issues. This ensures the utmost safety of both equipment and personnel, mitigating risks associated with electrical faults.
Application Location
Ideal for deployment across a diverse range of settings including power plants, substations, petrochemical facilities, metallurgical steel rolling mills, light industry textile factories, residential areas, high-rise buildings, and more. Wherever electrical energy needs to be managed and protected, this switchgear stands ready to deliver exceptional performance.
