KYN28A-12 Indoor Metal - Clad Withdrawable Switchgear
The KYN28A-12 Indoor metal-clad withdrawable switchgear (hereinafter referred to as the switchgear) is a sophisticated power distribution apparatus engineered for 3.6 - 24 kV, three-phase AC 50Hz single-bus sectionalized systems, delivering exceptional performance and versatility. It fulfills multiple essential functions across diverse power systems:
- Power Plant Applications: This switchgear is meticulously crafted for the power transmission of medium- to small-sized generators in power plants, ensuring the seamless transfer of electrical energy generated by these generators to the broader power grid or other associated systems, enhancing operational efficiency.
- Substation and Distribution Applications: Within substations in the power distribution network and in the power systems of factories, mines, and enterprises, this switchgear plays a pivotal role in power receiving and transmission. It facilitates the smooth distribution of power to various end-users and facilities, ensuring reliability and effectiveness.
- Motor Starting: This equipment is also crucial for the starting of large high-voltage motors. By expertly controlling the electrical current during motor startup, it provides essential protection to the motor from potential damage caused by over-current or voltage surges.
Functionally, the switchgear is meticulously designed to control, protect, and monitor the electrical system. It adheres to stringent international and national standards, specifically fulfilling the requirements of IEC298 and GB3906-91. This rigorous compliance ensures its unmatched reliability, safety, and compatibility in a wide array of applications.
In terms of component compatibility, in addition to being compatible with domestic VS1 vacuum circuit breakers, the switchgear can be seamlessly integrated with renowned international and domestic components such as VD4, 3AH5 from Siemens, domestic ZN65A, and VB2 from GE. This extensive versatility in component selection allows for greater flexibility in system design and customization, meeting diverse operational needs.
To cater to specific requirements for wall-mounting installation and front-end maintenance, the switchgear is equipped with a specialized current transformer. This design feature empowers operators to perform maintenance and inspections conveniently from the front of the cubicle, enhancing the overall maintainability and accessibility of the equipment. Ultimately, the KYN28 indoor metal-clad withdrawable switchgear represents a high-performance power distribution device that harmoniously combines reliability, compatibility, and user-friendly features, making it an ideal choice for modern power systems.
