一、概述变压器油箱制造中,焊接过程存在的质量问题如夹渣和末焊透等不易检查出,常常待到运输或使用一段时间后才予暴露。因而发生漏渗油现象,严重影响变压器安全可靠的运行。补焊堵漏的工作量虽不大,但辅助工作却非常可观,其耗资远远大于直接费用。如要出动大型起重运输设备,滤油机、存油罐等,牵涉人力也十分多,尤其停车时间所造成的间接损失又与其供电范围有直接关系。如果遇上主变压器,将波及全厂、全系统迫于生产停顿。找出一种快速经济及简便的堵漏方法是十分有价值的课题。
First, an overview Transformer fuel tank manufacturing, the quality of the welding process problems such as slag and the end of welding penetration is not easy to check out, often until after the transport or use for some time before exposure. Leakage and oil leakage occurs, seriously affecting the safe and reliable operation of the transformer. Although the workload of repair welding plugging is not large, but the auxiliary work is very impressive, the cost is far greater than the direct costs. If you want to dispatch large lifting and transport equipment, oil filters, storage tanks, etc., involves a lot of manpower, especially the indirect loss caused by parking time and its power supply range has a direct relationship. If you encounter the main transformer, will affect the whole plant, the whole system forced to stop production. It is a very valuable topic to find out a quick and economical and simple plugging method.
