Background

The common box bus is used for connecting the high-voltage station service loop, the transformer substation, the generator and the transformer. At present, the domestic common-box bus mostly adopts an aluminum shell, an internal bus is supported by an insulator, and an inspection cover plate is designed at the top. The common-box bus has long path and a large number of cover plates, and the cover plates need to be detached one by one during maintenance and then installed one by one after being cleaned. When the cover plate is disassembled, the sealing strip is easy to deform and break due to the sliding of the cover plate or fall off due to the loss of the viscosity of glue, so that the sealing strip needs to be replaced again as long as the cover plate is disassembled during maintenance at every time. When the cover plate sealing strip is installed, the joint surface needs to be cleaned, and the sealing strip is aligned with the edge of the cover plate and firmly adhered, so that the sealing strip is prevented from falling into the common box to cause short circuit fault, and the working efficiency is seriously influenced; because of the apron is great heavier, easily makes the sealing strip collide with and drop when the dress is compound, this influences the actual sealed effect of case generating line altogether, makes the case generating line waterproof and moisture proof performance reduction altogether that is in outdoor wind-blown sunshine and rain and drenches, leads to inside generating line support insulator to wet, causes the insulating effect of insulator not good, has the potential safety hazard.
