，liru，duididuanlu、相間短路等等但是。不管是哪種原因造成的短路。對運行中的變壓器都是非常有害的副邊短路直接危及到變壓器的壽命和安全運行。

想xiang要yao解jie決jue電dian源yuan變bian壓ya器qi突tu發fa短duan路lu這zhe一yi問wen題ti，首shou先xian要yao明ming白bai，突tu發fa短duan路lu是shi如ru何he造zao成cheng的de。我wo們men知zhi道dao，當dang變bian壓ya器qi接jie觸chu容rong量liang較jiao大da的de電dian網wang時shi，常chang規gui是shi要yao求qiu必bi須xu切qie斷duan電dian源yuan或huo排pai除chu故gu障zhang的de，如ru果guo不bu按an照zhao常chang規gui進jin行xing，那na麼me變bian壓ya器qi將jiang幣bi砂sha決jue被bei燒shao毀hui這zhe是shi因yin為wei當dang變bian壓ya器qi副fu邊bian短duan路lu時shi。將jiang產chan生sheng一yi個ge高gao於yu其qi額e定ding電dian流liu20～30倍bei的de短duan路lu電dian流liu。根gen據ju磁ci式shi平ping衡heng式shi可ke知zhi。副fu邊bian電dian流liu是shi與yu原yuan邊bian電dian流liu反fan相xiang的de。副fu邊bian電dian流liu對dui原yuan邊bian電dian流liu主zhu磁ci通tong起qi去qu磁ci作zuo用yong。由you於yu電dian磁ci的de慣guan性xing原yuan理li一yi次ci側ce要yao保bao持chi主zhu磁ci通tong不bu變bian。必bi然ran也ye將jiang產chan生sheng一yi個ge很hen大da的de電dian流liu來lai抵di消xiao副fu邊bian短duan路lu電dian流liu的de去qu磁ci作zuo用yong
，這zhe樣yang，就jiu使shi兩liang種zhong因yin素su的de大da電dian流liu彙hui集ji在zai一yi起qi，作zuo用yong在zai變bian壓ya器qi的de鐵tie芯xin和he繞rao組zu上shang，在zai變bian壓ya器qi中zhong將jiang產chan生sheng一yi個ge很hen大da的de電dian磁ci力li，這zhe個ge電dian磁ci力li作zuo用yong在zai繞rao組zu上shang，可ke以yi使shi變bian壓ya器qi繞rao組zu發fa生sheng嚴yan重zhong的de畸ji變bian或huo崩beng裂lie。另ling外wai這zhe也ye會hui產chan生sheng高gao出chu其qi允yun許xu溫wen升sheng幾ji倍bei的de溫wen度du。致zhi使shi變bian壓ya器qi在zai很hen短duan的de時shi間jian內nei被bei燒shao毀hui。
