变压器有载分接开关新检测技术探讨

A Discussion on a New Checking Technology for Transformer On-load tap-changers

变压器有载分接开关在电力系统中的作用日益突出，加强其技术监督已是势在必行。以往对其检测必须吊出芯体方能进行，现在开发不吊芯的新检测技术，不仅大幅度减少测试工作量，而且能有效发现以往无能为力的动态异常现象，有助其安全运行。

The function of transformer OLTCin power system has been conspicuous day by day.To strengthen technical supervision on it is imperative. In the past changer body must be hung outwhen testing But now the new technologywhithout hanging it out has been developed. Theuse of the new technology can not only greatly reduce test work load and detect effectively the abnormal phenomena in dynamic state, which couldnot be detected before,but also can make its operation safe.
