Product Description
Switchgear is a vital piece of electrical equipment engineered for the seamless operation of opening, closing, controlling, and safeguarding electrical systems. It plays an essential role throughout the generation, transmission, distribution, and energy conversion processes in power systems, ensuring optimal performance and protection.
Structure
High Voltage Switchgear: This sophisticated unit typically consists of several compartments, including the busbar room, circuit breaker room, secondary control or instrument room, and feeder room. Each compartment is strategically isolated with robust steel plates for enhanced safety. For instance, in the KYN28A-12 model, the upper section houses the instrument room, the middle is dedicated to the circuit breaker room, and the lower section is reserved for the cable room.
Low Voltage Switchgear: Distinguished by its installation methods, it is available in fixed and drawer types. The drawer type features a stationary cabinet body complemented by a versatile, movable device part, offering flexibility and convenience.
Internal Components
The internal mechanics of the switchgear are comprehensive, incorporating critical components such as circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and an array of protective devices, all meticulously designed for superior functionality.
Classification
Switchgear is categorized based on various parameters: By circuit breaker installation, it is classified into movable and fixed types; By cabinet structure, it is divided into open, metal enclosed, and metal enclosed armored types; Voltage levels distinguish it into high-voltage (above AC1000V) and low-voltage (below AC1000V) switchgear; Specifically, its voltage waveform classification includes AC and DC switchgear; Additionally, based on application, it is segmented into incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, and more, each serving a distinct purpose.
Effect
Control Function: This feature enables precise connectivity and disconnection of circuits, facilitating the start-stop control of power equipment efficiently and reliably.
Protection Function: Engineered to respond instantly to circuit anomalies such as overloads, short circuits, and leakages, this feature automatically interrupts the circuit, thereby safeguarding the equipment and personnel from potential hazards.
Application Location
This switchgear finds its application across diverse and demanding environments, including power plants, substations, petrochemicals, metallurgical steel rolling, light industry textiles, factories, and mines. It is equally suited for residential areas and high-rise buildings, reflecting its versatility and reliability.
