KYN28A-12 Indoor Metal-Clad Withdrawable Switchgear
The KYN28A-12 indoor metal-clad withdrawable switchgear, commonly known as 'the switchgear,' is a sophisticated power distribution solution engineered for systems operating at 3.6 - 24 kV, three-phase AC 50Hz single-bus sectionalized configurations. It performs several essential functions, making it an indispensable component across diverse power systems:
- Power Plant Applications: Designed chiefly for medium-to-small generators in power plants, it facilitates seamless transmission of electrical energy, ensuring that the power generated reaches the grid or other connected systems with optimal efficiency.
- Substation and Distribution Applications: In substations of the distribution network, and within the power infrastructures of factories, mines, and enterprises, the switchgear is critical for receiving and distributing power efficiently. It ensures that power is reliably delivered to different customers and facilities.
- Motor Starting: The switchgear is also utilized for initiating large high-voltage motors, controlling electrical currents during startup to prevent over-current or voltage surges, thus protecting the motor from potential damage.
Functionally, the switchgear is crafted to manage, shield, and supervise electrical systems. It adheres to both international and national standards, notably conforming to IEC298 and GB3906-91. This compliance guarantees its dependability, safety, and versatility across a broad spectrum of applications.
Regarding component compatibility, beyond accommodating domestic VS1 vacuum circuit breakers, the switchgear integrates with renowned global and domestic components such as VD4, Siemens' 3AH5, the domestic ZN65A, and GE's VB2. This adaptability in component integration enhances system design flexibility and customization.
To cater to specific wall-mounting needs and facilitate front-end maintenance, the switchgear includes a specially designed current transformer. This feature allows operators to conduct maintenance and inspections from the cubicle's front, significantly improving the equipment's maintainability and accessibility. In summary, the KYN28 indoor metal-clad withdrawable switchgear stands out as a high-performance power distribution device, blending reliability, adaptability, and ease of use.
