Switchgear Structure
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.
