Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power distribution cabinet supplies, and more specifically, to a power distribution cabinet splicing structure. Background Art
[0002] There are different opinions about the three boxes of the spliced distribution cabinet, but they mainly refer to the power distribution box and the lighting distribution box (there are also dual power switching boxes), the meter box (or the meter box with distribution function), and the control box (control of power equipment, such as water pumps, fans, etc.). That is, the three boxes refer to: distribution box, meter box, and control box. The three boxes in the building refer to the floor box (floor distribution box), the meter box (that is, the unified meter box), and the household box, that is, the indoor switch box of each household. It is classified according to the requirements of the power supply system and the place of use (primary distribution equipment, secondary distribution equipment, and final distribution equipment), or it is called the main distribution box, distribution box, and switch box. For a long time, the three boxes have been welded structures. The steel plates are welded into boxes as a whole after several bends. The welding workload is large, and the shell is painted after welding. The shell is large in size, difficult to spray, and poor painting in dead corners. Restricted by environmental protection policies and regulations, welding and painting have a great impact. The use of spliced structures has always been the result of efforts by all parties. Direction, low-voltage cabinets and medium-voltage cabinets were also welded frame type in the early days. Now, low-voltage cabinets with welded frames are almost invisible. The assembled type has good precision, no welding deformation, and uses aluminum-zinc plate or galvanized plate. No surface treatment such as spraying is required. The appearance is beautiful, non-standard design is easy, and other advantages make the switch cabinets better and better. Schneider's iPM distribution box and ABB's ARTU are all spliced distribution boxes. All prefabricated steel plates, components, standard parts, etc. are packaged in a box. After arriving at the panel factory, a worker can splice the box together with a tool. Modular and flexible components ensure that various solutions can be adapted to meet technical requirements, just like assembled furniture, modular combination, small packaging and convenient transportation.
[0003] During the assembly process of modular splicing distribution cabinets, due to the fit of the assembly parts, the joints of the distribution cabinets are prone to external impurities penetrating into the interior of the distribution cabinets. In addition, when the splicing distribution cabinets are used in the external environment, rainwater from the outside can easily penetrate into the equipment through the gaps in the distribution cabinets, causing corrosion damage to the electronic components inside the equipment.
