KYN28A-12 Indoor Metal-Clad Withdrawable Switchgear
The KYN28A-12 This indoor metal-clad withdrawable switchgear (hereinafter referred to as the switchgear) is a state-of-the-art power distribution apparatus meticulously engineered for 3.6 - 24 kV, three-phase AC 50Hz single-bus sectionalized systems. It is designed to perform multiple critical functions across various power systems with unparalleled efficiency:
- Power Plant Applications: Primarily harnessed for the power transmission of medium-to-small generators within power plants, this switchgear ensures the seamless delivery of electrical energy produced by these generators to the power grid or other connected systems, optimizing operational efficiency.
- Substation and Distribution Applications: Within substations of the power distribution network as well as in the power systems of industrial entities such as factories, mines, and enterprises, this switchgear is pivotal in facilitating power reception and transmission. It ensures the smooth and reliable distribution of power to various end-users and facilities, promoting operational continuity.
- Motor Starting: This switchgear is also a key player in starting large high-voltage motors. By regulating the electrical current during motor startup, it protects the motor from potential damage caused by over-current or voltage surges, thus enhancing motor durability.
Designed with cutting-edge technology, the switchgear is equipped to control, protect, and monitor the electrical system. It is fully compliant with both international and national standards, specifically adhering to the stringent requirements of IEC298 and GB3906-91. This compliance assures users of its reliability, safety, and compatibility across a diverse range of applications.
Showcasing exceptional component compatibility, besides accommodating domestic VS1 vacuum circuit breakers, the switchgear can be seamlessly integrated with renowned international and domestic components like VD4, 3AH5 from Siemens, domestic ZN65A, and VB2 from GE. This flexibility in component selection empowers greater freedom in system design and customization.
To address the specific demands of wall-mounting installation and front-end maintenance, the switchgear is outfitted with a specialized current transformer. This design innovation enables operators to perform maintenance and inspections conveniently from the front of the cubicle, significantly boosting the equipment's maintainability and accessibility. In essence, the KYN28 indoor metal-clad withdrawable switchgear stands as a high-performance power distribution device, merging reliability, compatibility, and user-centric features.
