三相220V變頻器接三相380V電壓，會(huì)造成什么結(jié)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(gè)拿著燒壞的變頻器找?guī)煾敌蓿�拆開(kāi)一看都燒黑了，板里面都用膠密封集成的看不到，所以問(wèn)一下。

儲(chǔ)能電解電容必爆，開(kāi)關(guān)電源應(yīng)也損壞，應(yīng)該不算太嚴(yán)重。不足每個(gè)變頻都有壓敏保護(hù)，壓敏保護(hù)在交流前端，一般只有雷擊等高壓才擊穿后燒快熔從而得保護(hù)
