KYN28A-12 Indoor Metal - Clad Withdrawable Switchgear
The KYN28A-12 indoor metal-clad withdrawable switchgear (hereinafter referred to as the switchgear) is an advanced power distribution apparatus meticulously engineered for 3.6 - 24 kV, three-phase AC 50Hz single-bus sectionalized systems. This versatile equipment plays an integral role in various power systems by providing:
- Power Plant Applications: Serving primarily in the transmission of power from medium-to-small generators in power plants, this switchgear ensures the seamless and efficient transfer of electrical energy from these generators to the power grid or associated systems.
- Substation and Distribution Applications: Essential in substations within the power distribution network and in the power systems of factories, mines, and enterprises, the switchgear is pivotal for power receiving and transmission. It facilitates the smooth and efficient distribution of power to various end-users and facilities.
- Motor Starting: Additionally, it is instrumental in the starting of large high-voltage motors. By managing the electrical current during motor startup, it protects 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 both international and national standards, specifically meeting the criteria of IEC298 and GB3906 - 91. This compliance guarantees its reliability, safety, and adaptability across a wide spectrum of applications.
In terms of component compatibility, the switchgear is not only compatible with domestic VS1 vacuum circuit breakers but can also be seamlessly integrated with renowned international and domestic components such as VD4, 3AH5 from Siemens, domestic ZN65A, and VB2 from GE. Such versatility in component selection enhances flexibility in system design and allows for extensive customization.
To accommodate specific needs for wall-mounted installation and front-end maintenance, the switchgear is equipped with a specialized current transformer. This innovative design allows operators to perform maintenance and inspections conveniently from the front of the cubicle, significantly enhancing the equipment's overall maintainability and accessibility. Overall, the KYN28 indoor metal-clad withdrawable switchgear epitomizes a high-performance power distribution device characterized by reliability, compatibility, and user-friendly features.
