所有接地線(xiàn)均應(yīng)一致編號(hào)，建立運(yùn)用記錄準(zhǔn)則，專(zhuān)人保管；接地線(xiàn)一致編號(hào)后，存放在**的接地線(xiàn)架上，按編號(hào)次序擺放；3. 攜帶型接地線(xiàn)的裝拆次序應(yīng)正確；4. 裝設(shè)接地線(xiàn)必須由兩人進(jìn)行；5. 攜帶型接地線(xiàn)在每次裝設(shè)曾經(jīng)應(yīng)具體查看，軟銅線(xiàn)無(wú)損壞，各處連接應(yīng)結(jié)實(shí)，損壞的接地線(xiàn)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(xiàn)作接地線(xiàn)或短路線(xiàn)之用；6.攜帶型短路接地線(xiàn)在通過(guò)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(xiàn)線(xiàn)鼻和匯流夾與多股銅質(zhì)軟導(dǎo)線(xiàn)之間的觸摸是否良好。一起,也可考核多股銅質(zhì)軟導(dǎo)線(xiàn)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(xiàn)的成組直流電阻實(shí)驗(yàn)時(shí),應(yīng)先丈量各接線(xiàn)鼻間兩兩的長(zhǎng)度,依據(jù)測(cè)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?；窘^緣安全工器具：是指安全工器具的絕緣強(qiáng)度能承受工作電壓的作用。</p><div
