三相220V變頻器接三相380V電壓，會造成什么結果？  接上冒煙了都 主板那部分能燒壞？還是全都能燒壞呢?                                                                                                                                                                                                                                                                                                                            日本的變頻器！今天在店里遇到一個拿著燒壞的變頻器找師傅修，拆開一看都燒黑了，板里面都用膠密封集成的看不到，所以問一下。

國內很少有輸入電源接3相220的呀。
