KYN28A-12 Indoor Metal-Clad Withdrawable Switchgear
The KYN28A-12 indoor metal-clad withdrawable switchgear, henceforth referred to as the switchgear, represents a pinnacle of engineering in the realm of power distribution apparatus. Engineered for 3.6 - 24 kV, three-phase AC 50Hz single-bus sectionalized systems, it offers unparalleled functionality and versatility in numerous power system applications:
- Power Plant Applications: A cornerstone in power plant operations, it is predominantly employed for the seamless and efficient transmission of electricity from medium-to-small generators to the broader power grid or other integral systems, solidifying its role in energy efficiency and reliability.
- Substation and Distribution Applications: Within the core of power distribution networks and across industrial power systems in factories, mines, and enterprises, this switchgear is imperative for power reception and transmission, ensuring uninterrupted and efficient distribution to an array of end-users and facilities.
- Motor Starting: It is adept at facilitating the starting process for large high-voltage motors, mitigating risks associated with over-current or voltage surges, thereby extending motor lifespan and optimizing performance.
Functionally, the switchgear is meticulously crafted to control, protect, and monitor electrical systems, conforming to both international and national standards, notably IEC298 and GB3906-91. This adherence guarantees its robustness, safety, and extensive applicability.
In terms of component integration, the switchgear boasts exceptional compatibility not only with domestic VS1 vacuum circuit breakers but also with esteemed international and domestic components like VD4, Siemens' 3AH5, domestic ZN65A, and GE's VB2. This remarkable versatility empowers system designers with boundless customization and design flexibility.
In alignment with the demands for wall-mounting installations and front-end maintenance, the switchgear is ingeniously equipped with a specialized current transformer. This allows operators to seamlessly perform maintenance and inspections directly from the front of the cubicle, markedly enhancing the equipment's accessibility and maintainability. In essence, the KYN28 indoor metal-clad withdrawable switchgear epitomizes high-performance power distribution, harmonizing reliability, compatibility, and user-centric features.
