壓ya敏min電dian阻zu器qi作zuo為wei一yi種zhong比bi較jiao常chang見jian的de電dian路lu保bao護hu元yuan件jian之zhi一yi
，已yi經jing在zai不bu同tong的de開kai關guan電dian路lu中zhong得de到dao了le廣guang泛fan應ying用yong，而er防fang雷lei壓ya敏min電dian阻zu器qi更geng是shi大da功gong率lv電dian源yuan等deng產chan品pin的de必bi備bei保bao護hu元yuan件jian。那na麼me，這zhe種zhong防fang雷lei壓ya敏min電dian阻zu器qi究jiu竟jing在zai平ping時shi能neng起qi到dao哪na些xie作zuo用yong
？它ta與yu普pu通tong的de壓ya敏min電dian阻zu器qi相xiang比bi又you有you哪na些xie不bu同tong呢ne？下xia麵mian就jiu讓rang我wo們men一yi起qi來lai看kan一yi下xia吧ba。

 

防fang雷lei壓ya敏min電dian阻zu器qi
，顧gu名ming思si義yi
，其qi主zhu要yao工gong作zuo就jiu是shi在zai雷lei暴bao天tian氣qi中zhong對dui用yong電dian器qi進jin行xing保bao護hu。這zhe種zhong壓ya敏min電dian阻zu器qi的de工gong作zuo原yuan理li是shi和he用yong電dian器qi並bing聯lian在zai電dian路lu中zhong，在zai用yong電dian器qi正zheng常chang工gong作zuo時shi由you於yu其qi本ben身shen的de電dian阻zu很hen大da
，因yin此ci基ji本ben不bu起qi作zuo用yong。而er當dang電dian路lu中zhong有you大da電dian流liu流liu過guo時shi
，防fang雷lei壓ya敏min電dian阻zu瞬shun間jian導dao通tong，並bing使shi得de電dian路lu中zhong的de電dian流liu全quan部bu流liu過guo防fang雷lei壓ya敏min電dian阻zu，從cong而er保bao護hu用yong電dian器qi。因yin為wei不bu同tong型xing號hao的de防fang雷lei壓ya敏min電dian阻zu保bao護hu水shui平ping是shi不bu一yi樣yang的de

，所suo以yi工gong程cheng師shi在zai進jin行xing防fang雷lei壓ya敏min電dian阻zu的de型xing號hao選xuan擇ze時shi，一yi定ding要yao依yi據ju設she備bei的de設she計ji要yao求qiu來lai進jin行xing選xuan擇ze，如ru果guo暫zan時shi沒mei有you合he適shi的de防fang雷lei壓ya敏min電dian阻zu
，可ke以yi不bu用yong，隻zhi是shi對dui用yong電dian器qi來lai說shuo比bi較jiao危wei險xian。
