一般來說，除了技術人員之外，我們可能不太清楚變壓器的一些內部電阻，比如什麼是R型變壓器的直流電阻？事實上，這些都是變壓器參數中的一些重要信息，通常與變壓器的質量和使用有關。讓我們和小r一起來看看什麼是變壓器直流電阻和絕緣電阻。
一yi般ban來lai說shuo，變bian壓ya器qi的de直zhi流liu電dian阻zu實shi際ji上shang是shi變bian壓ya器qi線xian圈quan的de電dian阻zu。變bian壓ya器qi出chu廠chang前qian，變bian壓ya器qi廠chang家jia會hui檢jian查zha導dao線xian連lian接jie處chu的de焊han接jie或huo機ji械xie是shi否fou連lian接jie良liang好hao，導dao線xian與yu套tao管guan、導dao線xian與yu分fen接jie開kai關guan的de連lian接jie是shi否fou完wan好hao。導dao線xian要yao求qiu的de電dian阻zu率lv是shi否fou在zai規gui定ding範fan圍wei內nei，各ge繞rao組zu電dian阻zu是shi否fou平ping衡heng。變bian壓ya器qi直zhi流liu電dian阻zu還hai包bao括kuo高gao壓ya繞rao組zu電dian阻zu和he低di壓ya繞rao組zu電dian阻zu。一yi般ban來lai說shuo，高gao壓ya繞rao組zu電dian阻zu誤wu差cha較jiao大da，因yin為wei變bian壓ya器qi線xian之zhi間jian的de連lian接jie是shi焊han接jie的de，隻zhi有you壓ya力li連lian接jie在zai高gao壓ya側ce，接jie觸chu容rong易yi出chu現xian問wen題ti，導dao致zhi電dian阻zu值zhi的de變bian化hua。
