Low-voltage switchgear classification: points from the structure fixed way: to meet the various electrical components securely fixed to determine the position of the cabinet. Cabinet generally cubic shape, such as the screen, box-type low-voltage switchgear and other wholesale prices, but also bevel body such as desktop and so on. This cabinet has a single row, but also arranged. In order to ensure the cabinet body position size, each member often take step combinations voltage switchgear sales, usually consisting of two pieces of first or left and right sides, and then the composition of the cabinet, or to meet the shape requirements, and then in turn connected to the internal cabinet support member. Length of the part of each edge of the composition of the cabinet must be correct (tolerance negative value), in order to ensure that all aspects of geometry, in order to ensure the overall shape requirements. For both sides of the cabinet, in consideration of the need for low-voltage switchgear arrangement, with no intervening uplift phenomenon. In addition, from the installation point of view, the bottom surface can not have subsidence phenomenon. In the arrangement of the installation, the ground level is a prerequisite, but dry whole and the cabinet itself has a certain degree of error, in an arrangement to try to counteract the lateral margin, and not caused by the difference between the accumulation, because the difference between the accumulation will cause deformation of the cabinet impact of bus links and produce components installed ectopic, stress concentration, and even affect the electrical life. Therefore, in the highest point of the foundation arrangement is appropriate for the installation of low-voltage switchgear Chaohu reference point, and then gradually expanded mat being ranked in the bottom surface of the whole of the dry and predictable under ideal conditions, it can also be taken from the middle to both sides of the expansion row way to make accumulated difference uniform. For ease of adjustment, offset tolerance accumulation, cabinet width tolerance is a negative value. Each member of the cabinet after the completion of the combination, should be shaped as needed to meet the size requirements of the shape and position of each part. On stereotypes or larger quantities should be fully considered by the cabinet manufacturing fixture, to ensure the correct unified structure, fixture for the proper datum in order to get the bottom surface, the fixture of each positioning block is arranged to facilitate the work of removing prevail, for outside the cabinet doors due to susceptible transportation and installation, the general uniform adjustment during installation. Low-voltage switchgear inspection and maintenance 1. The instrument signal, switch position status indication should correspond to the three-phase load, three-phase voltage indication is correct. 2. The various parts of the entire apparatus without abnormal ring or smell; means the surface is clean and complete. 3. vulnerable to external shocks and dusty place, you should check the protective cover of electrical equipment, arc chute loose, is clean. The circuit breakers, contactors pull solenoid is normal, with or without excessive noise or overheating of the windings. 5. Strengthening abnormal weather occurs check tour. 6. equipment failure, check the fuse operation when the focus and protective devices, and equipment within the scope of the accident presence or absence of burns or destroyed, with or without other abnormalities like.
