作者在调试检修GP60—CR13—1型高频设备的实践过程中发现,用以往技术资料和说明书规定的理相法来理相,费时又不精确,解决不了理相中可能遇到的一些难以预料的复杂问题。为此,本文提出了一种借助普通双踪电子示波器或单踪示波器检测相序来理相的新方法。新方法只需要一次测试、一次判别、一次停机总倒线,便能很快解决理相问题。 In the process of debugging and overhauling GP60-CR13-1 high-frequency equipment, the author found that it is difficult and inaccurate to solve the problems that may be encountered in using the technical data and specification methods specified in the previous technical documents and specifications Expected complex problems. To this end, this paper presents a new method of detecting the phase sequence with a common dual-tracking electronic oscilloscope or a single-track oscilloscope. The new method only needs a test, a judgment, a total downtime downtime, we can quickly solve the problem of appearance.
