●The instrument door equipped with electrical components is connected to the frame with multiple strands of soft copper wire. The installation parts in the cabinet are connected with knurled screws between the frame, and the whole cabinet constitutes a complete grounding protection circuit

●The cabinet top coat can be made of polyester orange-shaped baking paint, which has strong adhesion and good texture. The whole cabinet is in matte tone, which avoids the glare effect and creates a more comfortable visual environment for the personnel on duty

●The top cover of the cabinet can be removed when needed, which is convenient for the assembly and adjustment of the main busbar on site, and the four corners of the cabinet roof are equipped with lifting rings for lifting and shipping

●The protection level of the cabinet is IP30, which can be selected between IP20~IP40 according to the requirements of the user's installation site

Electrical performance

1. Basic electrical parameters

2. Main circuit scheme

The main circuit of the GGD cabinet is designed with 129 schemes and a total of 298 specifications (excluding schemes and specifications derived from the functional changes of auxiliary circuits and changes in control voltage).

ފަހެًmong them: GGD1 type, 49 schemes, 123 specifications

GGD2 type, 53 schemes, 107 specifications, GGD3 type, 27 schemes, 68 specifications

The main circuit scheme was selected by soliciting the opinions of the majority of design and use departments, increasing the needs of power plants, and increasing the rated current to 3150ފަހެً, which is suitable for distribution transformers of 2000KVފަހެً and below.

In addition, GGJ1 and GGJ2 capacitor compensation cabinets are designed to meet the needs of reactive power compensation, with 4 main circuit schemes and a total of 12 specifications.

4. Main busbar

When the rated current is 1500ފަހެً and below, a single copper bar bus is used. When the rated current is greater than 1500ފަހެً, double copper bar busbars are used. The lap surfaces of the busbars are treated with tin enamel process.

5. Selection of electrical components

a. GGD cabinets mainly use more advanced electrical components that can be mass-produced in China. Such as ME, DZ20, DW15, CW1, CM1, etc.

b. HD13BX and HS13BX rotary operated knife switches are special components designed by NLS to meet the needs of the unique structure of GGD cabinets, which change the operation mode of the mechanism, retain the advantages of old products, and are a practical model electrical component.

c. If the design department selects new electrical components with better performance and more advanced technology according to the needs of users, because the GGD cabinet has good installation flexibility, it will generally not cause manufacturing and installation difficulties due to updating electrical components.
