近年我厂有两台340、600千伏安的中频焊接变压器一次绕组铜管线圈裂口,发生漏水事故,且漏水部位均发生在变压器里层。这种变压器系采用一、二次重迭型绕制,线圈组数很多,冷却水管也多。铁芯上还分别装有14根冷却水管。加上次级电流很大,分别为一万安和一万五千安以上,故无法直接修补,那怕漏水处裂口很小,也必须将变压
In recent years, our factory has two 340,600 KVA intermediate frequency welding transformer primary winding brass coil rips, water leakage accident occurred, and leakage occurred in the transformer layer inside. This type of transformer uses one, two overlapping type winding, a large number of coil sets, cooling water pipes and more. The core is also equipped with 14 cooling pipes. Coupled with the secondary current is very large, respectively, one million and more than one thousand five thousand security, it can not be directly repaired, even if the leakage gap is very small, but also must be transformers
