What are the characteristics of GGD type low-voltage complete switchgear?

GGD structure introduction

The cabinet of GGD type AC low-voltage distribution cabinet adopts the type of general-purpose cabinet, the frame is assembled with 8MF cold-formed steel locally welded, and the parts of the general-purpose cabinet are designed according to the modular principle, and there are mounting holes of 20 molds. The high coefficient of generalization enables the factory to realize pre-production, which not only shortens the manufacturing cycle but also improves the working efficiency.

The design of GGD cabinet takes into full consideration of the heat dissipation problem in 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 inside the cabinet heat up, the heat rises and is discharged through the slots at the upper end, while the cold air is constantly added to the cabinet by the slots at the lower end, so that the sealed cabinet is shaped into a natural air duct from bottom to top to achieve the purpose of heat dissipation.

GGD cabinet in accordance with the requirements of modern industrial product modeling design, to use the golden ratio of the method of designing the cabinet exterior and the division of each part of the dimensions, so that the whole cabinet of the United States now generous, a new look.

The cabinet door is connected with the frame by pivot movable hinges, which is easy to install and dismantle, and the folded edge of the door is embedded with a mountain-type rubberized strip, and the embedded strip between the door and the frame has a certain compression line phase which can prevent the door from colliding with the cabinet body directly, and it also improves the door's protection level. Instrumentation door with electrical components with multi-stranded soft copper wire connected to the frame, the cabinet mounting parts and the cabinet frame with knurled screws connected to the cabinet constitutes a complete grounding protection circuit.

Flexible expansion capability

The main circuit of GGD cabinet is designed with 129 programs, totaling 298 specifications (excluding the programs and specifications derived from the functional changes of auxiliary circuits and control voltage changes).

GGD1 type 49 schemes 123 specifications

GGD2 type 53 programs 107 specifications

GGD3 type 27 programs 68 specifications

The design of auxiliary circuits is divided into two parts, the power supply scheme and the power plant scheme, and there is enough space in the GGD cabinet to install secondary components.

The GGD cabinet mainly adopts the more advanced electrical components that can be mass-produced domestically, and at the same time, according to the principle of economy and reasonableness, it retains part of the available old products under the premise of fully considering the feasibility, and does not use the obsolete products.
