KYN28A-12 Indoor Metal-Clad Withdrawable Switchgear
The KYN28A-12 indoor metal-clad withdrawable switchgear, affectionately termed as 'the switchgear,' stands as a top-tier power distribution marvel, adeptly crafted for 3.6 - 24 kV, three-phase AC 50Hz single-bus sectionalized systems. It fulfills an array of essential roles across diverse power environments:
- Power Plant Applications: Primarily engineered for the power transmission of medium-to-small generators within power plants, it ensures the seamless flow of electrical energy from these generators to the power grid or other integrated systems, optimizing efficiency and performance.
- Substation and Distribution Applications: Within substations and power distribution networks, as well as in the power frameworks of factories, mines, and enterprises, the switchgear is indispensable in power reception and transmission. It facilitates the unhindered distribution of power to various end-users and facilities with precision.
- Motor Starting: Crucial for initiating large high-voltage motors, it meticulously controls the electrical current during startup, safeguarding the motor against probable harm from over-current or voltage spikes, thus ensuring longevity and reliability.
Functionally, this switchgear is meticulously engineered for the control, protection, and surveillance of the electrical system. It complies with both international and national standards, particularly meeting IEC298 and GB3906 - 91 requirements, ensuring unmatched reliability, safety, and compatibility across a broad spectrum of applications.
In terms of component integration, beyond compatibility with domestic VS1 vacuum circuit breakers, the switchgear can also seamlessly incorporate renowned international and domestic components like VD4, Siemens' 3AH5, domestic ZN65A, and GE's VB2. This broad component adaptability offers unparalleled flexibility in system design and customization.
To address the unique demands of wall-mounting installation and front-end maintenance, the switchgear features an innovative current transformer. This strategic design empowers operators to perform maintenance and inspections effortlessly from the front of the cubicle, augmenting overall equipment maintainability and accessibility. In essence, the KYN28 indoor metal-clad withdrawable switchgear emerges as a superior power distribution solution, blending reliability, compatibility, and ease-of-use.
