KYN28A-12 Indoor Metal-Clad Withdrawable Switchgear
The KYN28A-12 The indoor metal-clad withdrawable switchgear (hereinafter referred to as the switchgear) is an advanced power distribution apparatus meticulously designed for 3.6-24 kV three-phase AC 50Hz single-bus sectionalized systems. This state-of-the-art switchgear performs an array of essential functions across various power systems:
- Power Plant Applications: At the heart of power plants, it is predominantly employed for the seamless transmission of power from medium-to-small generators. This guarantees the effective conveyance of electrical energy produced by these generators to the power grid or any other interconnected systems, ensuring optimal efficiency and performance.
- Substation and Distribution Applications: Within substations of the power distribution network and industrial power systems of factories, mines, and enterprises, this switchgear is pivotal in receiving and transmitting power. It enables the flawless distribution of power to diverse end-users and facilities, ensuring uninterrupted energy flow and operational excellence.
- Motor Starting: It is also instrumental in initiating large high-voltage motors. By adeptly managing electrical current during motor startup, it prevents potential damage from over-current or voltage surges, therefore extending the durability and reliability of the motors.
Functionally, this switchgear is engineered to control, protect, and monitor the electrical system with precision. It complies with international and national standards, specifically IEC298 and GB3906-91, ensuring its reliability, safety, and compatibility across a broad spectrum of applications.
In terms of component compatibility, beyond its compatibility with domestic VS1 vacuum circuit breakers, the switchgear can also be seamlessly integrated with components from reputed international and domestic brands such as VD4 , 3AH5 from Siemens, domestic ZN65A, and VB2 from GE. This versatility in component selection allows for enhanced flexibility in system design and customization, catering to diverse needs.
To cater to specific wall-mounting installation and front-end maintenance requirements, the switchgear is furnished with a specialized current transformer. This innovative design feature empowers operators to carry out maintenance and inspections conveniently from the front of the cubicle, boosting the overall maintainability and accessibility of the equipment. Ultimately, the KYN28 indoor metal-clad withdrawable switchgear stands as a high-performance power distribution marvel, combining reliability, compatibility, and user-friendly attributes for a superior energy management experience.
