配電箱原理

    配電箱原理

    配電箱是按電氣接線要求將開關設備
、測量儀表、保bao護hu電dian器qi和he輔fu助zhu設she備bei組zu裝zhuang在zai封feng閉bi或huo半ban封feng閉bi金jin屬shu櫃gui中zhong或huo屏ping幅fu上shang，構gou成cheng低di壓ya配pei電dian箱xiang。正zheng常chang運yun行xing時shi可ke借jie助zhu手shou動dong或huo自zi動dong開kai關guan接jie通tong或huo分fen斷duan電dian路lu。故gu障zhang或huo不bu正zheng常chang運yun行xing時shi借jie助zhu保bao護hu電dian器qi切qie斷duan電dian路lu或huo報bao警jing。借jie測ce量liang儀yi表biao可ke顯xian示shi運yun行xing中zhong的de各ge種zhong參can數shu，還hai可ke對dui某mou些xie電dian氣qi參can數shu進jin行xing調tiao整zheng
，對dui偏pian離li正zheng常chang工gong作zuo狀zhuang態tai進jin行xing提ti示shi或huo發fa出chu信xin號hao。
