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. The panel and the partition plate are made of imported cold-rolled sheet and adopt the acid-washing phosphating electrostatic spray-proof process for anti-corrosion technology, and the cabinet color is specified by the user. The interior of the cabinet is treated with a hot galvanizing process. In order to enhance ventilation and heat dissipation, ventilation holes are provided at the bottom and upper part of the cabinet, and the wire mesh is used to prevent the small animals. For the convenience of lifting, the top corner of the cabinet is equipped with a lifting ring. Considering the use of the cable outlet, a knockout hole is provided at the bottom of the cabinet, and a sheath sleeve that meets the requirements of the construction drawing size is prepared.
2. The design of the GGD cabinet fully takes into account the heat dissipation 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 to form a natural air passage from the bottom to the end for heat dissipation.
3. GGD cabinet according to the requirements of modern industrial product design, using the golden ratio method to design the cabinet shape and the size of each part of the division, which are beautiful and generous, fresh. The hinge of the cabinet door is connected with the frame, which is convenient for installation and disassembly. A mountain-shaped rubber 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 cracking the cabinet and also increases the degree of protection of the door. The instrument door with electrical components is connected to the frame by lots of soft copper coins. The mounting piece and the frame in the cabinet are connected by knurled screws, and the whole cabinet constitutes a complete grounding protection circuit.
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).
1. The shell is locally welded and assembled with 8MF cold-formed steel.Mounting holes arranged by E=20mm and E=100mm modules are arranged on the frame to improve the universality of product assembly.The panels and baffles are made of imported cold rolled sheet and adopt pickling, phosphating, electrostatic spraying, anticorrosive process.Cabinet internal treatment using hot dip galvanizing process.In order to strengthen ventilation and heat dissipation, the bottom and upper part of the cabinet have ventilation and heat dissipation holes, and steel wire mesh sealing cover, to prevent small animals to enter.For the convenience of lifting, the cabinet top four corners are equipped with rings.Considering the use of cable outlet, in the bottom of the cabinet set knock hole, and prepare to meet the construction drawing size requirements of the leather line sleeve.
2. When designing the GGD cabinet, the heat dissipation problem in the operation of the cabinet is fully considered.There are different Numbers of heat sink holes at both ends of the cabinet, when the electrical components in the cabinet heating, heat rise, through the upper end of the tank hole discharge, and the cold wind constantly by the bottom end of the tank hole supplement into the cabinet, make the sealed cabinet body from the bottom up to form a natural ventilation channel, to achieve the purpose of heat.
3, GGD ark according to the requirements of modern industrial product modelling design, the method that USES golden section ratio to design cabinet body appearance and the segmentation size of each part, beautiful and easy, face is new.Cabinet door USES turn axle activity hinge and frame to be linked together, installation, disassemble is convenient, the folding place of the door is embedded a hill model rubber model strip, the inlaid strip between door and frame when close the door has certain compression stroke, can prevent the door and cabinet body to collide directly, also raised the protection class of the door.The instrument door equipped with electrical components is connected to the frame with multiple strands of soft copper.Knurled screws are used to connect the installation parts and the frame in the cabinet. The whole cabinet constitutes a complete grounding protection circuit.
