随着电力工业的不断发展,变压器的总容量和单台容量有了很大增加。由于各单位在提高安装质量,加强运行中的监视、维护和检修工作,充分发挥设备使用能力,及时消除缺陷,提高安全运行水平等方面作了许多工作,几年来的运行情况是好的。但也发生了一些事故,存在一些缺陷。特别是一些高压大容量的变压器在运行中发生事故,不仅损坏了设备,而且修复工期长,比较困难,又影响了多发、多供电。
With the continuous development of power industry, the total capacity of transformer and single capacity have greatly increased. Since all the units have done a lot of work in improving the quality of installation, strengthening the monitoring, maintenance and overhauling work in operation, giving full play to the capability of using equipment, eliminating defects in time, and improving the safe operation level, the operation status in recent years has been good. However, some accidents happened and there were some shortcomings. In particular, some high-voltage high-capacity transformers in operation in an accident, not only damaged the equipment, and repair a long period of time, more difficult, but also affected the multiple, multi-supply.
