三相220V变频器接三相380V电压，会造成什么结果？  接上冒烟了都 主板那部分能烧坏？还是全都能烧坏呢?                                                                                                                                                                                                                                                                                                                            日本的变频器！今天在店里遇到一个拿着烧坏的变频器找师傅修，拆开一看都烧黑了，板里面都用胶密封集成的看不到，所以问一下。

答：会爆炸（电容器）烧坏电子元件和线路板。
