一般来说，当你拿到一台有故障的变频器，再上电之前首先要用万用表检查一下整流桥和IGBT模块有没有烧，线路板上有没有明显烧损的痕迹。

具体方法是：用万用表(好是用模拟表)的电阻1K档，黑表棒接变频器的直流端(-)极，用红表棒分别测量变频器的三相输入端和三相输出端的电阻，其阻值应该在5K-10K之间，三相阻值要一样，输出端的阻值比输入端略小一些，并且没有充放电现象。然后，反过来将红表棒接变频器的直流端(+)极，黑表棒分别测量变频器三相输入端和三相输出端的电阻，其阻值应该在5K-10K之间，三相阻值要一样，输出端的阻值比输入端略小一些，并且没有充放电现象。否则，说明模块损坏。这时候不能盲目上电，特别是整流桥损坏或线路板上有明显的烧损痕迹的情况下尤其禁止上电，以免造成更大的损失。
