Бронированное съемное распределительное устройство переменного тока в металлическом корпусе серии KYN28-12

1.Product Overview and Scope of Use

KYN28-12 armored removable metal enclosed switchgear (hereinafter referred to as "switchgear") is a type of mechanical and electrical equipment imported from abroad

A new type of product designed and developed on the basis of advanced manufacturing technology can replace various old types of metal enclosed switchgear, such as KYN1-

10. JYN2-10, GFC-10 and other series products. Its products have the following obvious advantages:

1. The outer shell of the product is completely made of aluminum coated zinc coated steel plate processed by CNC machine tool and formed by multiple bending and then assembled with bolts

High mechanical strength effectively ensures the neatness and beauty of the product. The cabinet door is sprayed with plastic coating, which has strong impact resistance and corrosion resistance

Erosion ability. The product housing has a protection level of IP4X.

2. The main switch of this product can be configured with Schneider EV12 vacuum circuit breaker and VS1 and other domestic series vacuum circuit breakers

To replace similar foreign products.

3. Regardless of which circuit breaker is selected, the air insulation distance of its bare conductor can be guaranteed to be greater than 125mm, and the composite insulation can be greater than

60mm。 Its circuit breakers have the unique advantages of long life, high parameters, less maintenance, and small size.

KYN28-12 armored removable metal enclosed switchgear is applicable to 3.6~12kV three-phase AC 50Hz power grid as an acceptable and "Distribute electrical energy and control, monitor, and protect circuits.". Can be used in single bus, single bus segmented systems, or dual bus systems. The switchgear shall comply with IEC298 "AC Metal Enclosed Switchgear and Control Equipment for Rated Voltages above 1kV and below 52kV" and IEC694 "High Voltage Switchgear and Control Equipment"Common Terms for Voltage Switches and Control Equipment, China GB3906 "3~35kV AC Metal Enclosed Switchgear" and DL404 "Indoor" Technical Conditions for Ordering AC High Voltage Switchgear, German DIN.VDE0670 "AC Switchgear with Rated Voltage Above 1 kV" and other standards Accurate requirements. It also has a complete and reliable anti misoperation function.

2、 Normal use conditions
