KYN28-12 Armored remove AC metal-enclosed switchgear

Product Overview
The KYN28-12 armored withdrawable AC metal enclosed switchgear is suitable for 3.6-12kV three-phase AC 50Hz power grids, as a means of receiving and distributing electrical energy, and for controlling, monitoring, and protecting circuits. Can be used for single busbar, single busbar segmented systems, or dual busbar systems. The switchgear complies with IEC298 "AC metal enclosed switches with rated voltage above 1kV and below 52kV" Equipment and Control Equipment ", IEC694" Common Terms for High Voltage Switchgear and Control Equipment ", China's" GB39063-35kV AC Metal Enclosed Switchgear "and DIA04" Ordering Conditions for Indoor AC High Voltage Switchgear ", Germany DIN The requirements of standards such as VDE0670 "AC switchgear with rated voltage above 1kV". And it has complete and reliable anti misoperation functions

Product Features
The KYN28-12 armored withdrawable AC metal enclosed switchgear (hereinafter referred to as the switchgear) is a new product designed and developed by our company based on absorbing advanced domestic manufacturing technology. It can replace various old types of metal enclosed switchgear, such as KYN1-12, JYN2-12 and other series products. Its products have the following obvious advantages:
The outer 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 coated with spray paint, which has strong impact resistance and corrosion resistance. The product casing has a protection level of IP4X. (Can be changed to iron plate according to customer needs)
2. The switch of this product can be equipped with ABB's VD4 vacuum circuit breaker, C3 series fixed load switch, and can also be configured with various domestic series vacuum circuit breakers (such as VS1, VH1, VK, ZN28) to replace similar foreign products
3. Regardless of the type of circuit breaker used, the air insulation distance of the bare conductor can be guaranteed to be greater than 125mm, and the composite insulation can be greater than 60mm. Their circuit breakers have the unique advantages of long lifespan, minimal maintenance, and small size

Structural characteristics of switchgear
The switchgear shall be designed according to the armored metal enclosed switchgear in GB3906-91. Figure 1: The switchgear consists of two main parts: a fixed cabinet body and a detachable component (referred to as a handcart). The outer shell of the cabinet body and the partitions of each functional unit are connected by bolts. The protection level of the switchgear enclosure is IP4X, and the protection level when the circuit breaker room door is opened is IP2X. The switchgear can be equipped with a vacuum circuit breaker handcart or a fixed load switch. It has overhead incoming (outgoing) lines, cable outgoing lines, and other functional solutions. The switchgear can be installed in a double cabinet arrangement, that is, installed in a back-to-back or face-to-face double row arrangement
Installation of switchgear
1. According to the engineering requirements and drawings, transport the switchgear to a specific location. If a row of longer switchgear is arranged (such as more than 10 units), the cabinet assembly work should start from the middle part
2. Use specific transportation tools such as cranes or forklifts, and it is strictly prohibited to use roller pry bars
3. Remove the circuit breaker handcart from the switchgear and store it properly elsewhere
4. Loosen the fixing bolts in front of the busbar compartment and remove the vertical partition 9
5. Loosen the fixing bolts of the horizontal partition 19 under the circuit breaker compartment and remove the horizontal partition
6. Release and remove the bottom plate 16
7. Remove cover plates 1 and 2 from the control cable tray on the left side of the switchgear; Remove the cover plate of the right front control cable tray at the same time
8. Install switchgear one by one on the basis, including both horizontal and vertical aspects. The unevenness of switchgear installation shall not exceed 2mm
After the switchgear is fully assembled (spliced), it can be connected to the foundation channel steel with anchor screws or welded firmly to the foundation channel steel with electric welding
