在介紹R型變壓器空載電壓和負載電壓的de差cha異yi之zhi前qian，讓rang我wo們men簡jian要yao了le解jie變bian壓ya器qi的de工gong作zuo原yuan理li。變bian壓ya器qi的de工gong作zuo原yuan理li實shi際ji上shang非fei常chang簡jian單dan。您nin可ke以yi將jiang變bian壓ya器qi的de主zhu繞rao組zu和he次ci繞rao組zu比bi作zuo兩liang個ge電dian感gan器qi。當dang交jiao流liu電dian壓ya添tian加jia到dao主zhu繞rao組zu時shi，在zai主zhu繞rao組zu上shang形xing成cheng電dian勢shi
，產chan生sheng交jiao變bian磁ci場chang。當dang二er次ci繞rao組zu電dian阻zu受shou到dao一yi次ci繞rao組zu電dian阻zu的de影ying響xiang也ye會hui產chan生sheng與yu一yi次ci繞rao組zu電dian阻zu磁ci場chang變bian化hua規gui律lv相xiang同tong的de感gan應ying電dian壓ya
，因yin此ci二er次ci繞rao組zu電dian阻zu輸shu出chu交jiao流liu電dian壓ya，這zhe是shi變bian壓ya器qi的de整zheng個ge變bian壓ya過guo程cheng。
