GGD low-voltage switchgear sets are used for power users in power plants, substations, industrial and mining enterprises, etc., as ac 50Hz, rated working voltage 380V, rated current 3150A power distribution system. Power conversion, distribution and control of lighting and power distribution equipment, GGD low-voltage switchgear with high breaking capacity. Rated short time withstand current up to 50KA. It is characterized by flexible scheme, convenient combination, strong practicability and novel structure.
GGD low-voltage switchgear set is one of the representative products of China's assembled and fixed panel switchgear. In line with GB7251 "low-voltage switchgear and control equipment", IEC60439 "low-voltage switchgear and control equipment" and other standards. Below small make up with you to understand the structure characteristics of GGD low-voltage switchgear set.
1. GGD low-voltage switch cabinet shell is assembled by local welding of 8MF cold-formed steel. There are mounting holes arranged by E=20mm and E=100mm modules respectively on the frame to improve the universality of product assembly. The panel and clapboard are made of imported cold-rolled sheet and adopt pickling, phosphating, electrostatic spraying and anti-corrosion technology. The internal treatment of the cabinet adopts hot dip galvanizing process. In order to strengthen ventilation and heat dissipation, there are ventilation and heat dissipation holes at the bottom and upper part of the cabinet, and steel wire mesh is used to seal the cover to prevent small animals from entering. To facilitate hoisting, the top four corners of the cabinet are equipped with rings. Considering the use of cable under the line, in the cabinet at the bottom of the knock hole, and prepare to meet the size of construction drawing requirements of the leather line cover.
2. The design of GGD cabinet fully takes into account the heat dissipation during the operation of cabinet. In cabinet put oneself in another's position up and down both ends all have different quantity come loose hot slot hole, when electric equipment element inside cabinet gives off heat, quantity of heat rises, discharge through upper end slot hole, and cold air is added by lower end slot hole into cabinet ceaselessly, make sealed cabinet put oneself in another's position form a natural ventilation from bottom to top, achieve come loose hot goal.
3. GGD cabinet adopts the golden ratio method to design the appearance of cabinet body and the segmentation size of each part according to the requirements of modern industrial product modeling design, which is beautiful and elegant with a new appearance. The cabinet door is connected with the frame by movable hinge of rotating shaft, which is convenient for installation and disassembly. There is a rubber and plastic bar of mountain type embedded in the folding edge of the door. When closing the door, the insert between the door and the frame has a certain compression stroke, which can prevent the door from directly collision with the cabinet body and improve the protection level of the door. The instrument doors with electrical components are connected to the frame with multiple soft copper COINS. Knurled screws are used to connect the installation parts and framework inside the cabinet. The whole cabinet constitutes a complete grounding protection circuit.
4. The main circuit of GGD cabinet is designed with 129 schemes, with a total of 298 specifications (excluding the schemes and specifications derived from the function changes of auxiliary circuits and control voltage changes). There are 123 specifications for 49 schemes of GGD1 type, 107 specifications for 53 schemes of GGD2 type and 68 specifications for 27 schemes of GGD3 type. In addition, GGJ1 and GGJ2 capacitor compensation cabinets are designed to meet the needs of reactive power compensation, and there are 4 main circuit schemes with a total of 12 specifications.
