GGD AC low-voltage distribution cabinet to 91 years to develop, fixed wiring and low voltage distribution cabinet, sub GGD1 \ GGD2 \ GGD3, different sub-current capability. (Hereinafter referred to as the distribution cabinet) used in power plants, substations, industrial enterprises and other power users as AC 50-60Hz, rated working voltage of 380 V, rated current up to 3150A of the distribution system, as power, lighting and power distribution power conversion equipment, distribution and control purposes. Products with segmented high capacity, dynamic thermal stability, the new structure, reasonable, practical electric scheme, the series of the use of strong, high level of protection. As a replacement product. Conditions 1. The ambient temperature is not higher than + 40 ℃, not lower than -5 ℃. 2. When the product installation, use the site altitude does not exceed 2000M. 3. The ambient air relative humidity less than 90% (+ 25 ℃). The equipment should be installed in the absence of severe vibration and shock place and inadequate electrical components are corrosion sites. 5. ambient air relative humidity at the highest temperature of 40 degrees, no more than 5%, at a lower temperature allows a greater relative humidity, should take into account the degree of change may occasionally produce condensation effects 6. equipment installed No severe vibration and shock place, and inadequate electrical components are corrosion sites 7. If you have special requirements can be resolved through consultation with the manufacturer 1. Structural features divided by purpose: by the cabinet, bus liaison cabinets, cabinet feed motor control cabinet, reactive power compensation cabinet, lighting distribution panel. 2. The cabinet structure: (1) cold-formed steel cabinet with 8MF assembled from local welding, respectively, according to E = 20mm mounting holes and modulus E = 100mm arranged on the frame, in order to improve the versatility of the product assembly. (2) with a high fire-retardant thermoplastic molding material PPO ZMJ type bus clip for modular binding, high mechanical strength and insulation. (3) 1000mm and 1200mm wide cabinet, front double doors symmetrical structure, 600mm and 800mm wide cabinet with integral door structure, followed by a two-door cabinet with symmetrical structure of the cabinet structure is not against a wall mounting structure. (4) the use of galvanized door hinge shaft connected with the architecture, installation, easy disassembly, folding at the door with a rubber inlay strip. Room (5) cabinet mounts and frame structure with ground knurled screws to form a complete grounding protection circuit. (6) of the cabinet cover, may need to be removed at the time, ease of assembly and adjustment of the main bus. Other features of applicability, the main component selection wide, a lot of domestic and imported brands are interchangeable good installation flexibility, even if the competent authorities forced out of certain products, due to the GGD-type cabinet has a good future installation flexibility, not because of modifications or updates installed components and cause distress modular standard parts design, with mounting holes mold, universal coefficient according to the current industrial product design requirements, using methods designed cabinet golden ratio and the size of each part of the split, so that the entire cabinet nice, new look GGD cabinet designed to take full account of the cabinet to run the heat problem, the upper and lower ends of the cabinet have a different number of cooling slots, when the electrical components inside the heat , heat rise, is discharged through the upper slot. The cold air from the bottom of the slot continuously added into the cabinet, so that the sealing of the cabinet to form a natural ventilation path from bottom to top, to achieve cooling purposes cabinet panel using spray technology, strong adhesion, good texture, the entire cabinet was matte tone, avoiding the glare effect, to create a duty more comfortable visual environment cabinet cover can be removed when needed, easy to assemble and adjust the site of the main bus, four corners of countertops with rings for lifting and shipping the entire cabinet protection rating of IP30, users can also according to the site environmental requirements between the IP20-IP40 choose to install and use the product after folding Edit this paragraph reach the place of receipt, we should first check the packaging is intact, the problem should be found in the relevant department to find the cause. For not installed immediately and should be under the normal conditions of use, and placed in the appropriate place. 1. Product installation products in the installation should be carried out installation diagram, basic channel and bolts owned by the user, the main bus junction repair installation should be smooth lap, handle clean, painted neutral Vaseline or take other measures, then tighten the bolt. 2. The product after installation, before running into the need for such projects up and down the inspection and testing. A. Check whether the cabinet finish off, the cabinet is dry and clean. B. electrical components of the operating mechanism is flexible, there should be no catching or operating force is too large phenomenon. C. Major appliances off is reliable and accurate. Auxiliary contacts are reliable and accurate off. D. instrumented with mutual inductance changes and polarity is accurate. E. bus connection is good, insulation supports, installation pieces and accessories are securely installed and reliable. F. auxiliary contact meets the requirements, fuse fuse specifications are correct, breaking and setting value meets the design requirements, the action is accurate. Contact G. circuit meets the requirements of electrical schematics. H. protection circuit system meets the requirements of I. with 500 volt megger insulation resistance shall not be less than 1 meg. 3 Cautions A. This product is not wall mounted, single-sided (front) operation, double door repair low voltage distribution cabinet. Maintenance access and door products must be tested for qualified personnel before entering the operation, inspection and maintenance. B. Air Circuit Breakers, after many, after hours, contact the local host will burn and produce carbon-based materials, the contact resistance increases, air circuit breakers should regularly use their maintenance and repair instructions.
