The analysis of the causes of leakage of transformer oil - packing quality

At the scene of the collapse of the transformer terminals can be electrical motor found at a time,leakage of oil terminal blocks most of fastening nut loose,install this doesn't mean that it electrical motor 24v did not tighten,with plane flange rubber gasket,for the first time after fastening tend to loose because of plastic deformation of the rubber gasket,need a second fastening.Transformer and our factory has been running for many years,there is no rubber gasket deformation problem,may explain why only is rubber gasket ageing lose elasticity,reducing the pressure on the surface of the flange connection.According to my years of experience in maintenance,air isolation rubber gasket to run more than ten years should not have what problem.Such as the transformer operation of our factory in nanjing,cichang has more than 20 years,did not find for porcelain set gasket electricalmotor1.blogspot.com aging oil leakage.Presumably liling porcelain production of transformer set gasket exist quality problems.
