The analysis of the causes of leakage of transformer oil - to solve the problem of oil leakage

1,product improvement:for porcelain set of oil leakage at the bottom of the transformer,because of the maintenance condition,can only be replaced with a new transformer.Will oil leakage transformer to return factory repair,and ask the manufacturer to improve the sealing structure.The transformer oil leakage,timely communication with the manufacturer recommended manufacturers choose better quality rubber gasket,explore the possibility of using new material packing.2,the process of making the maintenance plan for now a terminal oil leakage transformer by Taiwan to asynchronous motor apply for stop service,timely deal with oil leakage.For found no oil leakage transformer maintenance plan,equipment stop service with a porcelain on the surface of the flange bolt fastening.During the overhaul of random overhaul of main transformer transformer terminal change once motor parts a gasket.3,the pass of maintenance process:in the transformer overhaul the repair technology to the health of equipment has a decisive role.

Pass of maintenance technique,in case for overhaul quality caused by defective equipment:such as wiring fever caused by poor contact,non-standard oil caused by false oil level and test unqualified,the bad weather caused insulation be affected with damp be affected with damp.In the concrete work of this www.facebook.com/dongfeng.motor notice.In particular,when a terminal assembly,porcelain set of inner arc bakelite pad should be paid attention to in installation surface must with porcelain set wall stick take,otherwise will lead to a terminal external after fastening flange surface tilt,make rubber gasket cannot even tighten and easy broken porcelain bushing.4,product selection,now know,a growing number of oil-immersed transformer is replaced by SF6 transformers,the use of SF6 transformer can reduce many electrical motor 24v make the daily maintenance work,the only worry is leak problem,now understand of SF6 transformer leakage rate in a few parts per thousand,but now the oil-immersed transformer oil leakage rate in percentage more than a dozen,even a few decades.I think that using SF6 transformers very much worth considering.
