Product Description
The Kyn28-12 Electrical Switchgear stands as a pivotal component in electrical systems, designed primarily for the crucial tasks of opening, closing, controlling, and safeguarding electrical equipment throughout the intricate processes of power systems' generation, transmission, distribution, and energy conversion. This essential switchgear ensures the seamless and secure management of power, making it indispensable in modern electrical applications.
Structure
High Voltage Switchgear: This sophisticated equipment typically comprises distinct sections such as the busbar room, circuit breaker room, secondary control room (often called the instrument room), and feeder room. Each compartment is meticulously isolated with robust steel plates to ensure safety and efficiency. In models like the KYN28A-12, the uppermost section hosts the instrument room, the central area accommodates the circuit breaker, while the lower section is dedicated to the cable room, establishing a well-organized structure for optimal functionality.
Low Voltage Switchgear: Based on the installation method of its components, it is categorized into fixed and drawer types. The drawer type switchgear is ingeniously designed with a stable cabinet structure and a dynamic movable device part, offering flexibility and convenience in various electrical settings.
Internal Components
The internal architecture of the switchgear is composed of critical elements including circuit breakers, isolating switches, load switches, operating mechanisms, transformers, and a variety of protective devices. These components work in harmony to deliver unmatched safety, reliability, and performance in power management.
Classification
Switchgear Classification: Depending on the circuit breaker installation method, switchgear is categorized into movable and fixed types. Based on cabinet structure, it is classified as open, metal enclosed, and metal enclosed armored types. Voltage levels further define them into high-voltage (above AC1000V) and low-voltage (below AC1000V) categories. Additionally, according to voltage waveform, they are segmented into AC and DC switchgear. By purpose, they diversify into incoming cabinets, outgoing cabinets, metering cabinets, compensation cabinets, etc., each tailored for specific utilities.
Effect
Control Function: The switchgear excels in its ability to connect and disconnect circuits, facilitating the start-stop control of power equipment seamlessly and efficiently, ensuring that operations remain smooth and uninterrupted.
Protection Function: In events of circuit anomalies such as overloads, short circuits, or leakages, the switchgear's protection function is activated to automatically sever the circuit, safeguarding both equipment and personnel from potential hazards, thereby ensuring operational safety and reliability.
Application Location
Versatile and robust, the Kyn28-12 Electrical Switchgear is perfectly suited for a wide array of applications, including power plants, substations, petrochemical industries, metallurgical steel rolling processes, light industry textiles, as well as factories, mines, residential areas, and high-rise buildings. Its adaptability and efficiency make it a cornerstone in diverse industrial and commercial settings.
