KYN28-12 type armored mid-mounted AC metal enclosed switchgear

Overview and scope of application of armored mid-mounted AC metal-enclosed switchgear:

KYN28A-12 armored mid-mounted AC metal-enclosed switchgear (hereinafter referred to as switchgear) is a new type of product designed and developed by the company on the basis of absorbing advanced manufacturing technology at home and abroad, which can replace a variety of old metal-enclosed switchgear, such as KYN1-12, JYN2-12 and other products. Widely used in 6KV/6.3KV/7.2KV/10KV/12KV/

22KV/24KV/33KV/35KV/40.5KV box-type transformer distribution switchgear, urban power grid transformation, residential areas, high-rise buildings, industrial and mining, hotels, shopping malls, airports, railways, oil fields, docks, highways and temporary power installations and other indoor and outdoor places. Its products offer the following clear advantages:

◆ The shell of the product is completely assembled by bolts, which has high mechanical strength, which effectively ensures the neatness and beauty of the product, and the switchgear door is coated with spray plastic, which has strong impact resistance

and corrosion resistance. The product housing has IP4X degree of protection. (It can be changed to iron plate according to customer needs).

◆ The switch of this product can be equipped with VD4 vacuum circuit breaker produced by ABB company, C3 series fixed load switch, and can also be equipped with a variety of domestic series vacuum circuit breaker (such as VSIVHI, VK, ZN28) to replace similar foreign products.

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

KYN28A-12 armored mid-mounted metal-enclosed switchgear is suitable for 3.6-12kV three-phase AC 50Hz power grid, which is used to receive and distribute electrical energy, and control, monitor and protect circuits. Can be used for single busbar, single busbar segmentation system, or double busbar system. The switchgear meets the requirements of IEC298 "AC metal-enclosed switchgear and control equipment with rated voltage above 1kV and 52kV and below", IEC694 "Temple Pressure Switch and Control Equipment Common Terms", China's GB3906 (3-35kV AC metal-enclosed switchgear) and DIA04 "Indoor AC high-voltage switchgear ordering conditions", German DIN.VDE0670 "AC switchgear with rated voltage IkV above" and other standards. And with perfect and reliable anti-misoperation function.

Normal conditions of use of armored mid-mounted AC metal-enclosed switchgear:

◆Ambient air temperature: upper limit +40°C, lower limit -10°C;

◆Relative temperature: daily average is not more than 95%, monthly average is not more than 90%;

◆ Altitude: not more than 1000m;

◆The intensity of the earthquake does not exceed 8 degrees;

◆No fire, explosion risk, serious pollution, chemical corrosion and severe vibration occasions. When the conditions of use exceed the above range, the user shall consult with the Company to determine the allowable scope and technical measures.
