KYN28A-12 Indoor Metal - Clad Withdrawable Switchgear
The KYN28A-12 Our indoor metal-clad withdrawable switchgear, hereafter referred to simply as 'the switchgear', stands out as an exceptional power distribution apparatus. It is meticulously designed to cater to 3.6 - 24 kV, three-phase AC 50Hz single-bus sectionalized systems, making it indispensable across various power systems for its multi-functional capabilities:
- Power Plant Applications: It excels in power transmission duties for medium-to-small generators housed in power plants. This ensures that the electrical energy generated is transmitted efficiently to either the power grid or supplementary connected systems, supporting optimal power distribution.
- Substation and Distribution Applications: Within substations embedded in the power distribution network, as well as in the power systems within factories, mines, and enterprises, the switchgear is crucial. It facilitates seamless power receiving and transmission, ensuring that power is effectively distributed to various end-users and facilities.
- Motor Starting: Another vital application is in the starting of large high-voltage motors. It adeptly manages electrical currents during motor startup, providing protection against potential damage from over-current or voltage surges, thereby enhancing motor longevity.
Designed with precision, the switchgear fulfills roles of control, protection, and monitoring within electrical systems. It adheres strictly to both international and national standards, particularly IEC298 and GB3906-91. Such compliance guarantees its reliability, safety, and compatibility across diverse applications, making it an industry-standard choice.
In terms of component compatibility, the switchgear boasts flexibility by integrating with domestic VS1 vacuum circuit breakers alongside globally recognized components such as VD4, Siemens' 3AH5, the domestic ZN65A, and GE's VB2. This broad compatibility facilitates extensive customization and adaptability in system design, catering to varied power system needs.
To address specific requirements for wall-mounting installations and front-end maintenance, the switchgear is ingeniously equipped with a specialized current transformer. This feature empowers operators to conveniently conduct maintenance and inspections from the front of the cubicle, significantly enhancing maintainability and accessibility. In summary, the KYN28 indoor metal-clad withdrawable switchgear is a powerhouse of performance, blending reliability, compatibility, and user-centric features for optimal electrical distribution.
