Basic Introduction to KYN28A-12 High and Low Voltage Switchgear

The outer shell is made of aluminum zinc coated steel plate bent and assembled with bolts, which has high mechanical strength and effectively ensures the neatness and beauty of the product. The cabinet door is coated with spray paint. The enclosure protection level is IP4X.

　　High and low voltage switchgearThe main switch can be configured with various domestic VS1 series vacuum circuit breakers, as well as VD4 (ABB) vacuum circuit breakers.

No matter what type of circuit breaker is selected. The air insulation distance of its bare conductor can be guaranteed to be greater than 125mm, and the composite insulation is greater than 60mm. Its circuit breakers have unique advantages such as long life, high parameters, low maintenance, and small size.

The product has complete and reliable anti misoperation functions.

　　The product meets the standards

GB3906 "3-35kV AC Metal Enclosed Switchgear", GB/T 11022 "Common Technical Requirements for High Voltage Switchgear and Control Equipment Standards", IEC60298 "AC Metal Enclosed Switchgear and Control Equipment for voltages above 1kV and below 50kV", DL/T404 "Technical Conditions for Ordering Indoor AC High Voltage Switchgear".

　　Main performance characteristics

The switchgear is designed according to the requirements of armored metal enclosed switchgear in GB3906-91. The overall structure consists of two main parts: a cabinet and a center mounted withdrawable component (i.e. handcart). The cabinet is divided into four separate compartments, with a protection level of IP4X for the outer shell. When the doors of each compartment and circuit breaker room are opened, the protection level is IP2X. It has overhead incoming (outgoing) lines, cable incoming and outgoing lines, and other functional schemes. After being arranged and combined, it can become a distribution device in various forms. Switchgear can be installed, adjusted, and maintained from the front, so it can be arranged back-to-back in a double arrangement and installed against the wall, improving the safety and flexibility of the switchgear and reducing its footprint.
