Presenting the KYN28A-12: An Indoor Metal-Clad Withdrawable Switchgear Solution
The KYN28A-12 This indoor metal-clad withdrawable switchgear, often simply referred to as the switchgear, is a state-of-the-art power distribution device. Designed for 3.6 - 24 kV, three-phase AC 50Hz single-bus sectionalized systems, it performs an array of vital functions within various power infrastructures:
- Power Plant Applications: Primarily, it is employed for the seamless transmission of power from medium to small generators within power plants. This ensures that the electric energy generated is efficiently transferred to the power grid or other interconnected systems, optimizing energy use and system efficacy.
- Substation and Distribution Applications: Within the power distribution network at substations, as well as in the electrical systems of factories, mines, and enterprises, this switchgear is indispensable. It facilitates the critical functions of power reception and distribution to ensure a steady and reliable power supply to various end-users and facilities.
- Motor Starting: Additionally, it is integral in starting large high-voltage motors. By managing the electrical current during motor initiation, it protects the motor from potential damage caused by over-current or voltage spikes, thereby ensuring smooth operations and longevity.
Functionally, the switchgear is engineered for precise control, robust protection, and comprehensive monitoring of the electrical system. It is rigorously compliant with both international and national standards, specifically IEC298 and GB3906-91, guaranteeing unparalleled reliability, safety, and compatibility across diverse applications.
In terms of component compatibility, the switchgear is not only compatible with domestic VS1 vacuum circuit breakers but also seamlessly integrates with renowned international and domestic components such as VD4, Siemens' 3AH5, domestic ZN65A, and GE's VB2. This flexibility in component selection empowers greater customization and adaptability in system design.
Equipped with a specialized current transformer, the switchgear is tailored to meet the needs of wall-mounting installations and front-end maintenance. This feature allows for convenient maintenance and inspections directly from the front of the cubicle, significantly enhancing the equipment's maintainability and accessibility. Overall, the KYN28 indoor metal-clad withdrawable switchgear stands as a high-performance power distribution device that harmonizes reliability, compatibility, and user-centered features.
