攜帶型接地線在每次裝設(shè)曾經(jīng)應(yīng)具體查看，軟銅線無損壞，各處連接應(yīng)結(jié)實(shí)，損壞的接地線應(yīng)及時(shí)修補(bǔ)或替換，制止運(yùn)用不符合規(guī)則的導(dǎo)線作接地線或短路線之用；6.攜帶型短路接地線在通過短路電流后，一般應(yīng)予以報(bào)廢；7. 實(shí)驗(yàn)規(guī)范：成組直流電阻實(shí)驗(yàn)用于考核攜帶型短路接地線線鼻和匯流夾與多股銅質(zhì)軟導(dǎo)線之間的觸摸是否良好。一起,也可考核多股銅質(zhì)軟導(dǎo)線的截面積是否符合要求,成組直流電阻實(shí)驗(yàn)采用直流電壓降法丈量,常用的丈量方法為電流-電壓表法,實(shí)驗(yàn)電流宜≥30A。進(jìn)行接地線的成組直流電阻實(shí)驗(yàn)時(shí),應(yīng)先丈量各接線鼻間兩兩的長度,依據(jù)測得的直流電阻值,算出每米的電阻值,其值如符合下表的規(guī)則,則為合格。消防標(biāo)志：其含義是向人們提供消防設(shè)施信息的圖形標(biāo)志。浙江隔離開關(guān)檢測</p><p
