تابلو برق ثابت ولتاژ پایین مدل GGD

GGD model low-voltage stationary complete switchgear:
GGD model lowvoltage stationary complete switchgear applies to power users such as power plant, transformer substation and industrial and mining enterprises, and plays the role of power conversion, distibution and control of power equipment, illumination equipment and distribution equipment in power distribution system of frequency 50Hz, rated operating voltage 380V and rated operating current up to 3150A.

Applying Ambient Conditions:  

1.Ambient air temperature should be no more than+40ºC and no less than -5ºC, and average temperature within 24h should beno more than +35ºC
2.Altitude should be 1000m, users of high altitude region should indicate altitude upon ordering, and the product can meet requirement of user for altitude below 4000m.
3.Relative humidity of ambient air should be no more than 50% under the highest temperature +40ºC, and larger relative humidity is allowed under low temperature (for example: 90% under temperature +20ºC).
4.The inclination from vertical plane shouldbe no more than 5° upon installation of equipment.
5.Equipment should be installed at location free from violent shock and impact, and location free from corrosion of electric appliance component.
6.User can negotiate with manufacturer to findout solution in case of special requirements.

Product Characteristics:

Cabinet body of lowvoltage stationary complete switchgear adopts general purpose cabinet, and framework is assembled through partial welding of molded section. Component of general purpose cabinet is designed as per modular theory, and is configured with 20mm modulus installation hole, and the general purpose factor is high; with adequate consideration of heat radition in cabinet during operation, different quantity of heat radiation holes are configured on both top bottom side of cabinet body. In accordance with modern industrial product shape design requirement, golden section ratio is adopted for design of cabinet body exterior and section dimension of all parts, so that overall appearance of cabinet is pretty and elegant. Cabinet door is connected with framework by rotating shaft type of moveable hinge, featuring convenient installation and dismantling. A reverse Tshape rubber strip is embeded on edge of door, the embeded strip between door and framework has certain compression travel upon closing of door, and can prevent direct impact between door and cabinet body, enhancing degree of protection of door. The instrument door installd with electric component is connected to framework by mulistrand flexible copper wire, knurled screw is used for connection between pats mounted in cabinet and framework, so that the entire cabinet consititutes an integrated grounding protection circuit. Cabinet roof can be dismanted if necessary for the sake of assembling and adjustment of main busbar on site, hoisting rings are installed at all four corners of cabinet roof for hoisting and loading. Degree of protection of cabinet body is IP30 and user can select between IP20~IP40 as per demand of environment.Low voltage switch cabinet applies to industries such as power plant, petroleum, chemical, metallurgy, textile and high building, and is used for power transmission, powerdistribution and electric energy conversion.
