GGD AC LV switchgear
GGD type AC low voltage switch cabinet is suitable for power plants, substations, factories and mines
GGD AC low-voltage switchgear is suitable for power distribution systems with AC 50Hz, rated working voltage 380V and rated working current up to 3150A in power plants, substations and factories and mining enterprises, and is used for power conversion, distribution and control of power, lighting and power distribution equipment. The product is a new type of low-voltage distribution cabinet designed according to the requirements of the majority of power users and design departments of the Ministry of Energy, in line with the principles of safety, economy, rationality and reliability. The product has the characteristics of high breaking capacity, good dynamic thermal stability, flexible electrical scheme, convenient combination, series, strong practicability, novel structure and high protection level. Can be used as a low-voltage switchgear replacement products.
Products in line with IEC60439-1, GB7251.12 and other latest standards.
Structural features
The main frame of the cabinet body is partially welded and assembled with 8MF cold-formed steel. The frame parts and special supporting parts are supplied by the fixed-point steel production plant to ensure the accuracy and quality of the cabinet body. The parts of the general cabinet are designed according to the module principle and have 20-mold mounting holes. The general coefficient is high, which can enable the factory to realize pre-production, which not only shortens the production and manufacturing cycle, but also improves work efficiency. The design of GGD cabinet fully takes into account the heat dissipation problem in the operation of the cabinet body. There are different numbers of heat dissipation slot holes at the upper and lower ends of the cabinet body. The cabinet door is connected with the frame by a rotating shaft type living hinge, which is convenient to install and disassemble. A mountain-shaped rubber strip is embedded at the folding edge of the door. When closing the door, the molding between the door and the frame has a certain compression stroke, which can prevent the door Direct collision with the cabinet body also improves the protection level of the door.
