The analysis of the causes of transformer oil leakage

 Seal:I plant oil leakage current transformer are mainly concentrated in four period of current transformer installed in the switching station,four period of current transformer is hunan liling cichang the mid - 90 - products,has been running more than eight years.Current transformer porcelain jacket with electrical motor expander and tank adopts hanging flange connection,this structure has to be eliminated,manufacturers are now used for pressure coil flange connection,compared generator generator set with the hanging type connection,pressure coil flange connection has the advantage that can make the flange surface stress more evenly.

Manufacturers of technical improvement,also can prove the existence of hanging join some shortcomings.Current transformer primary winding through the upper porcelain set of asynchronous motor four terminals,derivation from the scene of the collapse of the transformer terminals can be found at a time,a terminal nanjing cichang the production of transformer and porcelain set of seal,the internal and external two flat pad.And a terminal liling,cichang production of transformer seal only outside a plane pad.Sealing wholesalemotor.blogspot.com structure differences make liling,cichang transformer produced a joint terminal sealing surface oil leakage occurred frequently.But now the liling manufacturer has also made the improvement to this sealing structure,in a terminal seal face to add a seam allowance,o-rings seals,how to be in one step.
