楼主

家里有一台设备，要用3相380VAC，但照明用电都是220VAC，请供电部门拉线，他们说这样那样不能拉。现请教，要用哪些电器元件才能把220VAC变为380VAC。这些元件是些什么品牌？什么型号。谢谢！

用输入220V输出三相220V的变频器加三相220V/380V的变压器可以实现。但成本较高

楼上的搞错了吧。应该是

输入220，输出380的变压器。

输入380的变频器。

吧。

你的变压器想接去哪里啊？变频器的输出接什么啊？

是变频器输出给变压器然后升压给电机不？

不如这样：买台发电机啊。（混账。开玩笑。）

控制线路加个变压器升压到380。线路不用改了。电机买个单相电机，要改动力线路。

如果自己不懂的话整台机的电器全改了。电机是换定的了。好过你买个大变压器和变频器啊。哪头大哪头小啊？变压器加变频器起码两千块的啊，而且线路还是要改。我换个电机几百，控制改了两百。才多少。旧电机还可以买一百几十。

你要是懂电器的，更好，更少。可能连电机都不用换。

引用yangguanglaonian 的回复内容：楼上说错了，好像没有输入220V输出380v的，只有220V\220V的变频器。

可以用输入220V输出380V的变频器

用单相变频直接驱动算了

输入单相220V,输出三相220V,可以接三相380V的电机的,就是劲小点

用变频器最好了，用三角形接法接电机。
