GGD low voltage switch cabinet

GGD type low-voltage switchgear is suitable for power distribution systems with AC 50Hz, rated working voltage and rated working current of 3150A for power users such as power plants, substations, factories and mining enterprises, as power conversion, distribution and control of power, lighting and power distribution equipment For use. GGD low-voltage switchgear is a new type of low-voltage switchgear designed based on the principles of safety, economy, reasonableness, and reliability in accordance with the requirements of the superiors in charge of the Ministry of Energy, the majority of power users and the design department. The product has the characteristics of high breaking capacity, good dynamic and thermal stability, flexible electrical scheme, convenient combination, series, strong practicability, novel structure, and high protection level. It can be used as an updated product of low-voltage switchgear.

GGD low-voltage switchgear complies with standards such as IEC60439 "Low-Volitage Complete Switchgear and Control Equipment,GB7251.1-1997 "Low-Voltage Complete Switchgear and Control Equipment Part 1:Type Test and Partial Type Test Complete Equipment".

 

Features

◆The GGD low voltage switchgear cabinet adopts the form of a general cabinet, and the frame is assembled by partial welding of 8MF cold-formed steel. The frame parts and special supporting parts are supplied by the designated steel manufacturer to ensure the accuracy and quality of the cabinet. The parts of the general cabinet are designed according to the principle of the module, and there are 20-module mounting holes, and the general coefficient is high. Can make the factory realize pre-production. This not only shortens the production cycle, but also improves work efficiency.

◆The GGD cabinet is designed with full consideration of heat dissipation during the operation of the cabinet. There are different numbers of heat dissipation holes on the upper and lower ends of the cabinet. When the electrical components in the cabinet heat up, the heat rises and is discharged through the upper slot, while the cold air is constantly replenished into the cabinet from the lower slot, making the sealed cabinet from the bottom The upper part forms a natural ventilation duct to achieve the purpose of heat dissipation.

◆According to the requirements of modern industrial product design, the GGD cabinet adopts the golden ratio method to design the appearance of the cabinet and the division size of each part, which makes the whole cabinet beautiful and fresh.

◆The cabinet door is connected to the frame with a hinge-type movable hinge, which is convenient for installation and disassembly. A mountain-shaped rubber plastic strip is embedded at the side of the door. When the door is closed, the embedded strip between the door and the frame has a certain compression stroke, which can prevent the door from directly colliding with the cabinet body and improve the protection level of the door.

◆The instrument equipped with electrical components is connected to the frame with multiple strands of soft copper wire. The installation part in the cabinet and the frame are connected with knurled screws, and the whole cabinet constitutes a complete grounding protection circuit.

◆The surface of the cabinet adopts plastic spraying process. Strong adhesion and good texture. The whole cabinet is in moon matte tone, avoiding the dazzling effect and creating a more comfortable visual environment for the staff on duty.

◆The top cover of the cabinet can be removed when needed to facilitate the assembly and adjustment of the main busbaron site. The four corners of the cabinet top are equipped with lifting rings for lifting and transfer.

◆The protection level of the cabinet is IP30, and users can also choose between IP20-IP40 according to the requirements of the use environment.

 

Conditions of Use

◆The ambient temperature should not be higher than +40℃, not lower than -5℃, and the average temperature within 24 hours should not be higher than +35℃. When it exceeds, the capacity should be reduced and run according to the actual situation.

◆For indoor use, the altitude of the place of use shall not exceed 2000m.

◆The relative humidity of the surrounding air does not exceed 50% when the highest temperature is+40℃, and a larger relative humidity is allowed at a lower temperature, such as90%at+20℃. It should be taken into account that it may be accidental due to temperature changes. The effect of condensation.

◆When the device is installed, the inclination to the vertical plane is not more than 5%, and the entire cabinet row is relatively flat.

◆The device should be installed in a place where there is no severe vibration and impact, and where the electrical components are not corroded.

Note: The user can negotiate with our company when the above-mentioned normal use conditions are exceeded.
