KYN28A-12 Indoor Metal-Clad Withdrawable Switchgear
The KYN28A-12 The indoor metal-clad withdrawable switchgear (hereinafter referred to as the switchgear) is a state-of-the-art power distribution apparatus tailored for 3.6 - 24 kV, three-phase AC 50Hz single-bus sectionalized systems. This advanced equipment provides a multitude of essential functions across diverse power systems:
- Power Plant Applications: It is strategically deployed for the seamless power transmission of medium-to-small generators within power plants, ensuring efficient integration of electrically generated energy into the power grid or other connected infrastructures.
- Substation and Distribution Applications: Inside substations of power distribution networks and the power systems found in factories, mines, and enterprises, the switchgear assumes a critical role in power reception and transmission, facilitating the streamlined distribution of electricity to various end-users and operational facilities.
- Motor Starting: It is effectively used for initiating large high-voltage motors. By regulating the electrical current during motor startup, it protects the motor from potential harm due to over-current or voltage spikes.
Functionally, the switchgear is engineered to control, safeguard, and monitor the electrical system. It complies with international and national standards, specifically fulfilling the stringent requirements of IEC298 and GB3906-91. This adherence ensures its unparalleled reliability, safety, and adaptability across a broad spectrum of applications.
In terms of component compatibility, beyond fitting with domestic VS1 vacuum circuit breakers, the switchgear can be integrated with prestigious international and domestic components like VD4, 3AH5 from Siemens, domestic ZN65A, and VB2 from GE. This wide-ranging component compatibility offers enhanced flexibility in system design and bespoke customization.
To address the particular needs of wall-mounting installation and front-end maintenance, the switchgear is equipped with a specialized current transformer. This design innovation allows operators to conduct maintenance and inspections effortlessly from the front of the cubicle, thereby boosting the overall maintainability and accessibility of the equipment. Overall, the KYN28 indoor metal-clad withdrawable switchgear stands as a pinnacle of high-performance power distribution, blending reliability, compatibility, and user-centric features.
