GTXGN-12 AC METAL SOLID INSULATED RING NETWORKSWITCHGEA

KYN28-12 armored movable AC metal enclosed switchgear is suitable for 3.6-12kv three-phase AC 50Hz power grid, as it receives and distributes electrical energy, and controls, monitors, and protects circuits.

It can be used for single bus, single bus segmented systems, or dual bus systems. The switchgear complies with the requirements of IEC298 "AC Metal Enclosed Switchgear and Control Equipment for Rated Voltages above 1kV and below 52k", IEC694 "Common Terms for High Voltage Switchgear and Control Equipment," China's "GB3906 3-35kV AC Metal Enclosed Switchgear" and DL/T404 "Indoor AC High Voltage Switching Cabinet Ordering Conditions," Germany's DIN VDE0670 "AC Switchgear for Rated Voltages above 1kV" and other standards.

Additionally, it has complete and reliable anti-misoperation functions.

KYN28-12 armored movable AC metal enclosed switchgear (hereinafter referred to as switchgear) is a new type of product designed and developed by our company on the basis of absorbing advanced domestic manufacturing technology. It can replace various old metal enclosed switchgear, such as KYN1-12, JYN2-12, and other series of products. Its products have the following obvious advantages:

1. The outer shell of the product is completely assembled with bolts, with high mechanical strength, effectively ensuring the neatness and aesthetics of the product. The cabinet door is coated with spray plastic, 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 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 selected, the air insulation distance of the bare conductor can be guaranteed to be greater than 125mm, and the composite insulation distance can be greater than 60mm. Its circuit breakers all have the unique advantages of long service life, less maintenance, and small size.

Environmental temperature: upper limit +40°C, lower limit -10°C

Relative humidity: daily average not exceeding 95%, monthly average not exceeding 90%

Altitude: not exceeding 1000m

Shock resistance: not exceeding 8 degrees

In situations where there is no risk of fire, explosion, severe pollution, chemical corrosion, or severe vibration.

Note: When ordering this product beyond the above conditions, please consult with our company.

GB 3906: 3-35KV AC Metal Enclosed Switchgear

GB/T1 1022: Common Technical Requirements for High Voltage Switchgear and Control Equipment Standards

DL/T404: Technical Conditions for Ordering Indoor AC High Voltage Switches

The switchgear is 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 withdrawable component (referred to as a handcart). The shell of the cabinet body and the partitions of each functional unit are connected by bolts. The protection level of the switchgear shell 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. Equipped with overhead incoming (outgoing) lines, cable outgoing lines, and other functional solutions, the switchgear can be installed in a double cabinet arrangement that is, in a back-to-back or face-to-face double row arrangement.

1. According to the engineering needs and drawings, transport the switchgear to a specific location. If a long row of switchgear is arranged (such as more than 10 units), the cabinet assembly work should start from the middle part.
2. It is strictly prohibited to use specific transportation tools such as cranes or forklifts to pry with rollers.
3. Extract the circuit breaker handcart from the switchgear and store it in a safe place.
4. Loosen the fixing bolts in front of the busbar compartment and remove the vertical partition.
5. Loosen the fixing bolts of the horizontal partition below the circuit breaker compartment and remove the horizontal partition.
6. Loosen and remove the base plate.
7. Remove cover plates from the control wire slot on the left side of the switchgear. Remove the right front control slot cover simultaneously.
8. Install switch cabinets one by one on the basis, including both horizontal and vertical aspects. The unevenness of switch cabinet installation shall not exceed 2mm.
9. After the switchgear is fully assembled (spliced), it can be connected to the foundation channel steel with foundation screws or welded firmly with the foundation channel steel with electric welding.

The following technical information should be provided when ordering:

1. Main circuit scheme diagram number, purpose, main line system diagram, distribution room layout plan, and arrangement configuration diagram, etc.
2. Requirements for control, measurement, and protection functions of switchgear, as well as requirements for other locking and automatic devices.
3. The model, specification, and quantity of the main electrical components inside the switchgear.
4. If a busbar bridge connection is required between switchgear or incoming cabinets, specific requirements such as the rated current carrying capacity of the busbar bridge, the span of the busbar bridge, and the height from the ground should be provided.
5. When switchgear is used in special environmental conditions, detailed instructions should be provided when ordering.
6. Negotiate with the manufacturer to resolve special requirements.
