GGD-type AC low-voltage power distribution cabinet is a new type of power distribution cabinet designed according to the requirements of the superior department of the Ministry of Energy, the majority of power users and the design department, based on the principles of safety, economy, reasonableness and reliability. The product has the characteristics of high breaking capacity, good dynamic thermal stability, flexible electrical scheme, convenient combination, strong seriality, practicability, novel structure and high protection level. It can be used as a replacement product for low-voltage switchgear.
1. The shell is assembled by partial welding of 8MF cold-formed steel. Mounting holes arranged in E=20mm and E=100mm modules are respectively arranged on the frame to improve the versatility of product assembly. 2. The design of the GGD cabinet fully considers the heat dissipation problem during the operation of the cabinet. There are different numbers of heat dissipation slots at the upper and lower ends of the cabinet. When the electrical components in the cabinet are heated, the heat rises and is discharged through the upper slot, and the cold air is continuously replenished into the cabinet by the lower slot to make the sealed cabinet Form a natural air passage from the bottom up to achieve heat dissipation.
3. The hinged hinge of the cabinet door is connected with the frame, which is convenient for installation and disassembly. A mountain-shaped rubber and plastic strip is embedded in the folded edge of the door. When the door is closed, the insert between the door and the frame has a certain compression stroke, which can prevent the door from being The direct collision of the cabinet also increases the degree of protection of the door.
4. The main circuit of the GGD cabinet is designed with 129 schemes and a total of 298 specifications (excluding the functional changes of the auxiliary circuits and the control schemes and specifications derived from the control voltage).
