Product Description

KYN28A-12 Armored Central AC Metal-enclosed Switchgear

KYN28A-12 armored central AC metal-enclosed switchgear hereinafter referred to as switchgear is a new product designed and developed by Baixing based on the absorption of advanced manufacturing technology at home and abroad. It can replace all kinds of old metal-enclosed switchgear. Such as KYN1-12, JYN2- -12 and other products.
Its products have the following distinct advantages:

1.1 The outer shell of the product is completely assembled from aluminum-zinc-copper plate by CNC machine tool and formed by bolts. It has high mechanical strength, effectively guarantees the neatness and beauty of the product, and the door is spray-coated. It has strong impact resistance and corrosion resistance. The product enclosure has an IP4X rating. Can be changed to iron plate according to customer needs.

1.2 The main switch of this product can be equipped with VB4 vacuum circuit breaker produced by ABB Company, C3 series fixed load switch, and also can be equipped with a variety of domestic series vacuum circuit breakers such as VS1, VHI, VK, ZN 28 to replace Similar products abroad.

1.3 Regardless of which circuit breaker is selected, the bare conductor air insulation distance can be guaranteed to be greater than 125mm, and the composite insulation is greater than 60mm. The circuit breakers have the unique advantages of long life, high parameters, low maintenance and small size.

KYN28A- 12 armored centrally-mounted metal-enclosed switchgear is suitable for 3.6--12KV three-phase AC 50Hz power grid, as a means of receiving and distributing electrical energy, and controlling, monitoring and protecting the circuit. Can be used for single busbars, single busbar segmentation systems or dual busbar systems. The switchgear complies with IEC298 AC metal-enclosed switchgear and control equipment with rated voltage above 1 KV and below 52KV, IEC694 Common Terms of High-Voltage Switch and Control Equipment, China GB3906 3--36KV AC Metal-Enclosed Switchgear and DIA04 Order AC high voltage switchgear ordering conditions, Germany DIN.VDE0670 AC switchgear with rated voltage above 1 KV and other standards. And has a complete and reliable anti-misoperation function.

Model and its meaning

Normal use condition

2.1 ambient air temperature: . upper limit 40 ° C, lower limit - 10 ° C;

2.2 Relative humidity: the daily average is not more than 95%, and the monthly average is not more than 90%;

2.3 Altitude: no more than 1000m;

2.4 The seismic intensity does not exceed 8 degrees;

2.5 No fire, explosion hazard, serious pollution, chemical corrosion and severe vibration.

When the conditions of use exceed the above range, the user should negotiate with our company to determine the allowable range and technical measures.


1 The electric heater should be turned on when the relative humidity is greater than 70%.

2 Where the altitude is more than 1000m, it shall be treated according to JB/Z102-71.

Operating mechanism technical parameters

Mechanical characteristics of VD4 and VS1-12 vacuum circuit breakers

When the circuit breaker is used to control a 3 - 10kV motor, if the starting current is less than 600A, a metal zinc oxide arrester must be added. The specific requirements are negotiated by the user and our company; when the circuit breaker is used to open the capacitor bank, the rated current of the capacitor bank is not It should be greater than 80% of the rated current of the circuit breaker.

Use and description

1. In the operation of the switchgear, in addition to the relevant regulations, the operator should also pay attention to the following problems:

1. 1 operating procedure

Although the switchgear is designed to ensure the correct interlocking of the operating procedures of the various parts of the switchgear, the push and exit of the various parts of the switchgear by the operator should be carried out strictly in accordance with the operating procedures and the requirements of this technical document, and should not be operated at will. It should not be forced to operate without analysis when the operation is blocked. Otherwise, it may cause equipment damage or even cause an accident.

1 1.1 Operation of circuit breaker cabinet without grounding switch

a. Insert the circuit breaker removable parts into the cabinet: Before the circuit breaker trolley is ready to be pushed into the cabinet from outside the cabinet, carefully check whether the circuit breaker is in good condition, whether there are missing parts, whether there are tools and other debris placed on the mechanism. Inside the box or switch, after confirming that ther
