GGD AC low-voltage power distribution cabinet is suitable for power users, power stations, substations, industry and commerce, communications and other power users AC 50Hz, rated working voltage 380V power distribution system, as the power conversion, distribution and control of power, lighting and power distribution equipment . GGD AC low-voltage power distribution cabinet is a new type of low-voltage power distribution cabinet designed in accordance with the requirements of the superior in charge of the Ministry of Energy, the majority of power users and the design department, in accordance with the principles of safety, economy, rationality and reliability. The product has the characteristics of high breaking capacity, good dynamic and thermal stability, flexible electrical scheme, convenient combination, strong series and practicability, novel structure and high protection level. GGD type AC low-voltage distribution cabinet complies with standards such as IEC61439 / GB7251 "Low-voltage switchgear and control equipment". ● Ambient temperature: The ambient air temperature is not higher than + 40 ° C, not lower than -15 ° C, and its average temperature is not higher than + 35 ° C within 24 hours. ● Ambient humidity: The air is clean, and the relative temperature does not exceed 50% at the maximum temperature of + 40 ° C. A higher relative temperature is allowed at a lower temperature, and 90% at + 20 ° C, but due to the temperature Changes may occasionally produce moderate condensation. ● Altitude: no more than 2000m; ● Earthquake intensity: no more than 8 degrees; ● Installation location: Indoors, there is no fire and explosion danger, no serious pollution, chemical corrosion and frequent severe vibration. ● When the equipment is installed, the inclination to the vertical plane should not exceed 5 °. ● If there are other special requirements, users should negotiate with our company to determine the allowable range and technical measures.
The GGD cabinet has good installation flexibility, and can choose components of various brands at home and abroad according to user needs. It will not cause difficulties in manufacturing and installation due to updating electrical components. HD13B (X) and HS13BX rotary operation knife switches are special components designed to meet the needs of the unique structure of the GGD cabinet. It changes the way the organization operates, retaining the advantages of older products. Is a new type of electrical components. GGD uses a special ZMJ-type combined bus clamp and insulation support to improve the dynamic stability of the main circuit. The bus bar clip is made of high-strength, high-flame-retardant PPO alloy material, which has high mechanical strength and insulation strength, good self-extinguishing performance, can withstand high dynamic and thermal stable impact forces, and the long-term allowable temperature can reach 120 ° C. 1) The cabinet of GGD AC low-voltage power distribution cabinet adopts the general cabinet form, and the frame is assembled by welding with 8MF L-shaped steel. Its rigidity and bearing capacity meet the installation requirements of electrical components. 2) The components of the universal cabinet adopt a modular design and have E = 20mm module mounting holes, which has a high universal coefficient. Allows the factory to achieve pre-production. Not only shorten the production cycle, but also improve work efficiency. 3) The GGD cabinet is designed in accordance with the requirements of modern industrial product modeling design, and adopts the golden section ratio method to design the appearance of the cabinet and the partition size of each part to make the whole cabinet beautiful and new. 4) The cabinet door is connected to the frame with a galvanized hinged hinge, which is easy to install and disassemble. The hem of the door is embedded with rubber plastic strips. When the door is closed, the molding strip between the door and the frame has a certain compression stroke to prevent the door from directly colliding with the cabinet and improve the protection level of the door. 5) The instrument door with electrical components is connected to the frame with multiple soft copper wires. The mounting parts in the cabinet are connected to the frame with knurled screws, and the entire cabinet forms a complete ground protection circuit to ensure ground continuity. 6) The surface of the cabinet is electrostatic sprayed with epoxy powder, which has strong adhesion and good texture. The whole cabinet has a matt hue, which avoids the dazzling effect and creates a more comfortable visual environment for the staff on duty. 7) The top cover of the cabinet can be removed when needed to facilitate the assembly and adjustment of the main bus on site. Four corners of the top of the cabinet are equipped with lifting rings for lifting and shipping.
