Used for power users such as power plants, substations, factories and mines, as AC 50-60Hz, rated working current up to 3150A in the power distribution system, as the power conversion, distribution and control of power, lighting and power distribution equipment.
The product has the characteristics of good dynamic and thermal stability, novel and reasonable structure, practical electrical scheme, strong serial usability, and high protection level. It can be used as an updated product.
The selection of electrical components
A. The GGD cabinet mainly adopts the more advanced electrical components that can be mass-produced in China, such as DW45, MCCB, DZ20, DW15, etc. At the same time, it also retains some of the usable components based on economic and reasonable principles and under the premise of full consideration of feasibility. Old products such as DZ10, etc., do not use obsolete electrical components.
B. HD13BX and HS13BX rotary-operated knife switches are special components designed by NLS to meet the needs of the unique structure of the GGD cabinet. It changes the operation mode of the mechanism and retains the advantages of the old products. It is a practical new type of electrical component. .
C. If the design department selects new electrical components with better performance and more advanced technology according to user needs, because GGD has good installation flexibility, it will generally not cause manufacturing and installation difficulties due to the update of electrical components.
D. In order to further improve the dynamic stability of the main circuit, NLS designed a ZMJ type combined bus clamp and insulating support for the GGD cabinet. The busbar clamp is made of high-strength, high flame-retardant PPO alloy material, with high insulation strength, good self-extinguishing performance and unique structure. It can be easily combined into a single busbar clamp or a double busbar clamp by adjusting the building block. The insulating support is a sleeve-type molded structure with low cost and high strength, which solves the defect of insufficient creepage distance of old products.
1. The instrument door equipped with electrical components is connected to the frame with the multi-strand soft copper wire. The installation parts in the cabinet and the frame are connected by knurled screws, and the whole cabinet constitutes a complete grounding protection circuit.
2. Polyester orange-shaped baking paint is used for the cabinet body finish. Strong adhesion and good texture. The whole cabinet is in matte tones, which avoids the dazzling effect and creates a more comfortable visual environment for the staff on duty.
3. The top cover of the cabinet can be removed when needed to facilitate the assembly and adjustment of the main bus on site. The four corners of the cabinet top are equipped with lifting rings for lifting and shipping.
4. The cabinet body protection grade is IP30, and users can also choose between IP20~IP40 according to the requirements of the use environment.
