KYN28A-12 Indoor Metal-Clad Withdrawable Switchgear
The KYN28A-12 The KYN28A-12 indoor metal-clad withdrawable switchgear (hereinafter referred to as the switchgear) is an advanced power distribution apparatus engineered for 3.6 - 24 kV, three-phase AC 50Hz single-bus sectionalized systems. This switchgear is pivotal in various power systems, fulfilling multiple essential functions:
- Power Plant Applications: Primarily employed for the power transmission of medium-to-small generators in power plants, this switchgear ensures the seamless and efficient transfer of electrical energy generated by these generators to the power grid or other integrated systems.
- Substation and Distribution Applications: Within substations in the power distribution network, as well as in the power systems of factories, mines, and enterprises, this switchgear is crucial for power receiving and transmission, facilitating the smooth distribution of power to various end-users and facilities.
- Motor Starting: Additionally, it is employed for the startup of large high-voltage motors. By effectively controlling the electrical current during motor startup, it protects the motor from potential damage due to over-current or voltage surges.
Functionally, the switchgear is meticulously designed to control, protect, and monitor the electrical system. Complying with both international and national standards, specifically IEC298 and GB3906-91, it guarantees reliability, safety, and compatibility across a broad spectrum of applications.
In terms of component compatibility, alongside being compatible with domestic VS1 vacuum circuit breakers, the switchgear seamlessly integrates with renowned international and domestic components such as VD4, 3AH5 from Siemens, domestic ZN65A, and VB2 from GE. This versatility in component selection offers enhanced flexibility in system design and customization.
To address specific wall-mounting installation and front-end maintenance requirements, the switchgear features a specialized current transformer. This design aspect allows operators to conveniently perform maintenance and inspections from the front of the cubicle, significantly enhancing the equipment's overall maintainability and accessibility. Overall, the KYN28 indoor metal-clad withdrawable switchgear stands out as a high-performance power distribution device that harmoniously combines reliability, compatibility, and user-friendly features.
