在zai使shi用yong小xiao型xing單dan相xiang隔ge離li變bian壓ya器qi之zhi前qian
，讓rang我wo們men先xian了le解jie一yi下xia我wo們men的de供gong電dian係xi統tong。通tong常chang
，在zai供gong應ying低di壓ya用yong戶hu時shi，中zhong國guo的de供gong電dian係xi統tong一yi般ban采cai用yong三san相xiang四si線xian係xi統tong

，即ji中zhong性xing線xian接jie地di。簡jian言yan之zhi
，普pu通tong居ju民min家jia中zhong的de一yi根gen電dian線xian是shi火huo線xian

，另ling一yi根gen是shi零ling線xian。它ta與yu地di球qiu同tong位wei。當dang人ren體ti接jie觸chu到dao熱re底di板ban時shi，電dian流liu會hui通tong過guo人ren體ti，與yu地di球qiu形xing成cheng電dian路lu
，造zao成cheng觸chu電dian的de危wei險xian。使shi用yong小型單相隔離變壓器更(geng)安(an)全(quan)

在zai我wo們men的de日ri常chang應ying用yong中zhong
，應ying選xuan擇ze單dan相xiang隔ge離li變bian壓ya器qi或huo三san相xiang隔ge離li變bian壓ya器qi您nin需xu要yao的de變bian壓ya器qi類lei型xing將jiang取qu決jue於yu您nin使shi用yong的de設she備bei類lei型xing。家jia庭ting使shi用yong的de小xiao型xing設she備bei通tong常chang使shi用yong小xiao型xing單dan相xiang隔ge離li變bian壓ya器qi，“三相”通常更適合高負荷大型行業。三相隔離變壓器可通過空氣對流自然冷卻或增加風扇冷卻
，主要用於高層建築
、高速收費站、地鐵、機場、工礦企業等大容量變壓器。

隔離變壓器的主要作用是什麼？
