由you於yu夏xia季ji雷lei電dian高gao發fa
，加jia之zhi高gao溫wen高gao濕shi的de環huan境jing因yin素su，很hen容rong易yi造zao成cheng並bing聯lian式shi的de高gao壓ya電dian容rong器qi組zu發fa生sheng過guo電dian壓ya過guo大da的de問wen題ti。在zai開kai關guan分fen閘zha過guo程cheng中zhong，傳chuan統tong的de並bing聯lian式shi電dian容rong器qi組zu很hen容rong易yi形xing成cheng電dian弧hu重zhong燃ran過guo電dian壓ya。我wo們men假jia設she開kai關guan在zai電dian壓ya最zui大da值zhi，電dian流liu過guo零ling時shi電dian弧hu會hui被bei熄xi滅mie
，高gao壓ya電dian容rong器qi也ye將jiang會hui處chu於yu充chong電dian狀zhuang態tai，其qi電dian壓ya保bao持chi在zai係xi統tong電dian壓ya的de最zui高gao值zhi。此ci時shi開kai關guan觸chu頭tou間jian的de電dian壓ya分fen別bie由you兩liang個ge電dian壓ya值zhi組zu成cheng，一yi為wei電dian容rong器qi電dian壓ya，另ling一yi個ge為wei電dian源yuan電dian壓ya，因yin此ci當dang電dian源yuan變bian為wei負fu的de最zui大da值zhi時shi，觸chu頭tou間jian的de電dian壓ya也ye會hui變bian成cheng電dian源yuan電dian壓ya的de2倍。

假jia如ru開kai關guan彈dan跳tiao或huo分fen閘zha速su度du慢man且qie滅mie弧hu性xing能neng不bu好hao
，開kai關guan弧hu隙xi絕jue緣yuan恢hui複fu的de速su度du低di於yu恢hui複fu電dian壓ya增zeng長chang的de速su度du
，那na麼me開kai關guan弧hu隙xi將jiang被bei擊ji穿chuan
，這zhe時shi形xing成cheng電dian弧hu重zhong燃ran，它ta的de過guo電dian壓ya可ke達da額e定ding值zhi的de4.5—5倍左右。

了le解jie了le過guo電dian壓ya過guo高gao問wen題ti所suo產chan生sheng的de原yuan因yin，接jie下xia來lai我wo們men需xu要yao依yi據ju現xian實shi狀zhuang況kuang來lai進jin行xing避bi雷lei器qi的de選xuan擇ze和he設she置zhi。通tong常chang情qing況kuang來lai看kan

，隻zhi要yao電dian源yuan不bu是shi架jia空kong線xian路lu引yin入ru，保bao護hu電dian容rong器qi的de避bi雷lei器qi最zui好hao采cai用yong氧yang化hua鋅xin避bi雷lei器qi。之zhi所suo以yi選xuan擇ze氧yang化hua鋅xin避bi雷lei器qi，是shi因yin為wei普pu通tong閥fa型xing避bi雷lei器qi在zai過guo電dian壓ya值zhi低di於yu避bi雷lei器qi的de放fang電dian電dian壓ya時shi，衝chong擊ji過guo電dian壓ya會hui迫po使shi電dian容rong器qi充chong電dian。直zhi到dao過guo電dian壓ya值zhi達da到dao避bi雷lei器qi的de放fang電dian電dian壓ya時shi
，閥fa型xing避bi雷lei器qi的de間jian隙xi被bei擊ji穿chuan，這zhe時shi電dian容rong器qi將jiang對dui避bi雷lei器qi放fang電dian。
