首shou先xian當dang電dian動dong葫hu蘆lu的de電dian源yuan線xian或huo者zhe是shi控kong製zhi電dian路lu被bei斷duan開kai時shi
，設she備bei顯xian然ran是shi無wu法fa啟qi動dong的de。那na麼me我wo們men可ke以yi檢jian查zha一yi下xia設she備bei的de電dian源yuan線xian或huo控kong製zhi電dian路lu，如ru果guo出chu現xian了le斷duan裂lie或huo者zhe接jie觸chu不bu良liang的de情qing況kuang，隻zhi要yao將jiang其qi修xiu複fu或huo者zhe是shi更geng換huan就jiu可ke以yi了le。其qi次ci電dian動dong葫hu蘆lu的de控kong製zhi電dian路lu中zhong也ye是shi有you保bao險xian絲si的de
，當dang保bao險xian絲si被bei異yi常chang電dian流liu燒shao斷duan
，電dian路lu會hui就jiu此ci斷duan開kai，如ru果guo保bao險xian絲si沒mei有you完wan全quan熔rong斷duan
，開kai關guan也ye會hui跳tiao開kai而er將jiang電dian路lu斷duan開kai，這zhe時shi電dian動dong葫hu蘆lu也ye就jiu不bu能neng使shi用yong了le，這zhe時shi隻zhi需xu要yao找zhao出chu保bao險xian絲si被bei燒shao毀hui的de原yuan因yin並bing進jin行xing更geng換huan就jiu可ke以yi了le。還hai有you一yi種zhong情qing況kuang，電dian動dong葫hu蘆lu有you一yi個ge相xiang位wei保bao護hu的de安an全quan防fang護hu裝zhuang置zhi，如ru果guo設she備bei電dian源yuan線xian的de相xiang位wei接jie錯cuo了le，相xiang位wei保bao護hu作zuo用yong就jiu會hui啟qi動dong
，強qiang製zhi性xing的de將jiang設she備bei啟qi動dong程cheng序xu鎖suo定ding。此ci時shi將jiang接jie錯cuo的de兩liang個ge相xiang位wei的de電dian源yuan線xian對dui調tiao

，就jiu可ke以yi解jie除chu鎖suo定ding，正zheng常chang的de啟qi動dong電dian動dong葫hu蘆lu。
