KYN28-12 High-Voltage AC Metal-Enclosed Switchgear

Overview

KYN28-12 high-voltage AC metal-enclosed switchgear is suitable for 3.6-12kV three-phase AC 50Hz power grid, as a means of receiving and distributing electric energy, and controlling, monitoring and protecting circuits. It can be used for single busbar, single busbar segmented system or double busbar system. The switchgear complies with the requirements of IEC298 "AC metal-enclosed switchgear and controlgear with rated voltage above 1kV and below 52kV", IEC694 "Common terms for high-voltage switches and controlgear", my country's GB3906-2006 "3.6kV~40.5kV AC metal-enclosed switchgear and controlgear", Germany's DIN.VDE0670 "AC switchgear with rated voltage above 1kV" and other standards. It also has a complete and reliable anti-misoperation function.

Features

KYN28-12 high-voltage AC metal-enclosed switchgear (hereinafter referred to as switchgear) is a new product designed and developed by our company based on the absorption of advanced manufacturing technologies at home and abroad. It can replace various old metal-enclosed switchgears, such as KYN1-12, JYN2-12 and other series products. Its products have the following obvious advantages:

·The shell of the product is completely assembled with bolts, which has high mechanical strength and effectively ensures the neatness and beauty of the product. The cabinet door is spray-coated with plastic, which has strong impact resistance and corrosion resistance. The product shell has an IP4X protection level. (It can be changed to iron plate according to customer needs).

·The switch of this product can be equipped with VD4 vacuum circuit breaker and C3 series fixed load switch produced by ABB. It can also be equipped with various domestic series vacuum circuit breakers (such as VS1, VH1, VK, ZN28) to replace similar foreign products.

·No matter which circuit breaker is selected, the air insulation distance of the bare conductor can be guaranteed to be greater than 125mm, and the composite insulation distance is greater than 60mm. The circuit breakers have the unique advantages of long life, low maintenance and small size.
