Standard specificationI. Overview:GGD fixed switch cabinet is suitable for 50HZ AC, 380V rated working voltage and 3150A rated working current distribution system of power plant, power plant, mining enterprise and other power users. It is used for power conversion, distribution and control of power, lighting and distribution equipment.GGD fixed switchgear is a new type of low-voltage distribution cabinet designed on the principle of safety, economy, reasonableness and reliability, according to the requirements of the superiors in charge of the Ministry of Energy, the vast number of power users and design departments. The product has the characteristics of high breaking ability, good dynamic and thermal stability, flexible electrical scheme, convenient combination, series, strong practicability, novel structure and high protection grade. It can be used as a replacement product of low-voltage switchgear.Fixed switchgear meets IEC 439 "Low Voltage Switchgear and Control Equipment", GB7251 "Low Voltage Switchgear Set" and other standards.Ⅱ.Type and Meaning　　GGD fixed switch cabinetⅢ. Conditions of use1. Ambient air temperature is not higher than + 40 degrees, not lower than - 5 degrees, and within 24 hours its average temperature is not higher than + 35 degrees.2. The relative temperature of ambient air should not exceed 50% when it is + 40 degrees. The maximum relative temperature is allowed at lower temperatures, such as 90 degrees at + 20 degrees. However, due to the change of temperature, moderate condensation may occur.3. For indoor use, the altitude of the place of use shall not exceed 2000 meters.4. It should be installed in places where there is no severe vibration and shock to make electrical components corroded.Ⅳ. Main electrical parametersGGD fixed switch cabinetV. Structural characteristics1. The cabinet body of GGD distribution cabinet is in the form of general cabinet. The frame is assembled by local welding of cold-formed steel plate. The frame parts and special supporting parts are supplied by our company to ensure the accuracy and quality of solids. The size and color of the cabinet can be customized by customers.2. When designing GGD cabinet, the problem of heat dissipation in cabinet operation is fully considered. There are different number of heat sink holes at the upper and lower ends of the cabinet. When the electric components in the cabinet are heated, the heat rises and is eliminated through the upper
