KYN28A-12 Indoor Metal-Clad Withdrawable Switchgear
The KYN28A-12 indoor metal-clad withdrawable switchgear (hereinafter referred to as the switchgear) is a sophisticated power distribution apparatus crafted for 3.6 - 24 kV, three-phase AC 50Hz single-bus sectionalized systems. It excels in executing multiple pivotal functions across diverse power systems, ensuring unparalleled reliability and efficiency:
- Power Plant Applications: This switchgear is chiefly deployed for the transmission of power from medium-to-small generators in power plants. It facilitates seamless and efficient transfer of the electrical energy generated, channeling it into the power grid or other integrated systems, thereby optimizing the plant's power distribution capabilities.
- Substation and Distribution Applications: Within substations across the power distribution network and within the power systems of factories, mines, and enterprises, this switchgear is indispensable for power reception and dissemination. It ensures a smooth and efficient power flow to various end-users and facilities, enhancing operational efficiency and service continuity.
- Motor Starting: The switchgear is also vital for initiating large high-voltage motors. By regulating the electrical current during motor startup, it provides essential protection, preventing damage from potential over-current or voltage spikes, thereby extending motor lifespan and performance.
Functionally, the switchgear is meticulously engineered to control, protect, and monitor electrical systems. It proudly adheres to international and national standards, specifically aligning with IEC298 and GB3906-91. This compliance affirms its commitment to reliability, safety, and versatility across a broad spectrum of applications.
In terms of component compatibility, the switchgear not only accommodates domestic VS1 vacuum circuit breakers but also integrates seamlessly with renowned international and domestic components such as VD4, 3AH5 from Siemens, domestic ZN65A, and VB2 from GE. This adaptability in component selection enhances system design flexibility and customization, ensuring tailored solutions for specific requirements.
To address the distinct demands of wall-mounting installation and front-end maintenance, the switchgear is outfitted with a specialized current transformer. This thoughtful design allows operators to execute maintenance and inspections effortlessly from the front of the cubicle, significantly elevating the equipment's maintainability and accessibility. Overall, the KYN28 indoor metal-clad withdrawable switchgear is a high-performance power distribution solution, embodying reliability, compatibility, and user-centric features.
