How to design an electrical control cabinet? Jiangsu Xukong will introduce it to you below. The function of the electrical control cabinet is to control the motion control, status monitoring and other switch values of the machine tool or equipment by the electrical control system. It can be said that the electrical control system is the brain of the machine tool. The basis of this system is to select and design a suitable electrical control cabinet.
The main components of the electrical control cabinet are single hardware. The electrical control cabinet includes a cabinet body, a mounting plate, a shelf, a heat dissipation device, an operation panel, a cabinet moving device, a lifting ring, a front door, a rear door, a left door, a right door, etc. According to the use requirements, the temperature of the electrical cabinet must also be thermally designed during the design of the electrical cabinet to ensure the normal operation of the system in the electrical cabinet. The electrical cabinet temperature design formula is as follows:
Internal heat loss P[W]≤ 6[W/M2;o;C]X surface area S[M2;]X rise temperature 13[o;C]. When the electrical cabinet is large enough and the heat dissipation of the system unit in the electrical cabinet is less than the surface area of the electrical cabinet, no special treatment is required. Heat dissipation can be achieved through the surface of the electrical cabinet without exceeding the allowable temperature.
When the surface area of the electrical cabinet cannot meet the requirements, heat must be dissipated through a heat exchanger.
Types and applications of electrical control cabinets: Electrical control cabinets are divided into high-voltage cabinets, low-voltage cabinets, and some are mixed cabinets of strong and weak electricity. In terms of structure, it mainly includes ordinary power electrical cabinets + operating tables. Piano consoles. Computer consoles. PC Rittal cabinets.
For the production of electrical cabinet sheet metal, it is first required to provide a reliable protection box for the electrical equipment in the cabinet, and at the same time, there must be good grounding. In actual production, the grounding screws in the cabinet are only galvanized screws, and they are fixed in the cabinet by welding, which makes the welding screws rust quickly. Moreover, the cabinet body should be sprayed with paint, baking paint and other anti-corrosion and aesthetic treatments in the electrical cabinet, so that the grounding screws become quasi-insulated screws, and their grounding effect will be greatly reduced.
