所謂絕緣(yuan)(yuan)，是(shi)指用絕緣(yuan)(yuan)材(cai)料(liao)把帶(dai)電(dian)(dian)體封(feng)閉起來，借(jie)以(yi)隔(ge)離(li)帶(dai)電(dian)(dian)體或(huo)不同電(dian)(dian)位的導(dao)體，使電(dian)(dian)流(liu)能按一定的通路流(liu)通。良好的絕緣(yuan)(yuan)是(shi)保證設備(bei)和(he)線路正常運行的必要(yao)條件(jian)，也是(shi)防(fang)(fang)止觸電(dian)(dian)事(shi)故的重要(yao)措施(shi)。絕緣(yuan)(yuan)材(cai)料(liao)往往還(huan)起著其他(ta)作用：散熱冷(leng)卻、機械支撐(cheng)和(he)固定、儲能、滅弧、防(fang)(fang)潮(chao)、防(fang)(fang)霉以(yi)及保護導(dao)體等。

電(dian)絕緣鞋（靴）的(de)適用范(fan)圍

新標準規定了(le)電絕緣鞋(xie)（靴(xue)）作(zuo)為(wei)從(cong)事電(dian)(dian)(dian)(dian)氣(qi)(qi)工(gong)(gong)作(zuo)的(de)安(an)(an)全(quan)(quan)(quan)輔助用具(ju)(ju)(ju)，作(zuo)為(wei)勞動安(an)(an)全(quan)(quan)(quan)管(guan)理(li)者，應清楚地認(ren)識(shi)(shi)這一點。往往有些電(dian)(dian)(dian)(dian)氣(qi)(qi)知識(shi)(shi)不足的(de)管(guan)理(li)者，誤認(ren)為(wei)6KV絕(jue)(jue)緣皮鞋(xie)(xie)或5KV布(bu)面(mian)絕(jue)(jue)緣鞋(xie)(xie)，應用范圍(wei)是6KV或5KV環境中，這是十分(fen)錯誤的(de)。電(dian)(dian)(dian)(dian)氣(qi)(qi)安(an)(an)全(quan)(quan)(quan)管(guan)理(li)中，把(ba)絕(jue)(jue)緣工(gong)(gong)具(ju)(ju)(ju)分(fen)為(wei)基本安(an)(an)全(quan)(quan)(quan)用具(ju)(ju)(ju)和輔助安(an)(an)全(quan)(quan)(quan)用具(ju)(ju)(ju)。所(suo)謂基本安(an)(an)全(quan)(quan)(quan)用具(ju)(ju)(ju)，是指(zhi)絕(jue)(jue)緣強度足以(yi)承受電(dian)(dian)(dian)(dian)氣(qi)(qi)運(yun)用電(dian)(dian)(dian)(dian)壓(ya)的(de)安(an)(an)全(quan)(quan)(quan)用具(ju)(ju)(ju)，如絕(jue)(jue)緣棒、絕(jue)(jue)緣夾鉗、絕(jue)(jue)緣臺(tai)（梯）。而輔助安(an)(an)全(quan)(quan)(quan)用具(ju)(ju)(ju)，是指(zhi)不足以(yi)承受電(dian)(dian)(dian)(dian)氣(qi)(qi)運(yun)行電(dian)(dian)(dian)(dian)壓(ya)，在(zai)電(dian)(dian)(dian)(dian)氣(qi)(qi)作(zuo)業中，配(pei)合(he)基本安(an)(an)全(quan)(quan)(quan)用具(ju)(ju)(ju)（如絕(jue)(jue)緣墊、絕(jue)(jue)緣鞋(xie)(xie)）不可以(yi)接觸帶電(dian)(dian)(dian)(dian)部分(fen)。但(dan)可以(yi)防止跨步電(dian)(dian)(dian)(dian)壓(ya)對人身(shen)的(de)傷害(hai)。絕(jue)(jue)緣皮鞋(xie)(xie)及布(bu)面(mian)絕(jue)(jue)緣鞋(xie)(xie)，主(zhu)要應用在(zai)工(gong)(gong)頻1000V以(yi)下作(zuo)為(wei)輔助安(an)(an)全(quan)(quan)(quan)用具(ju)(ju)(ju)。

電絕緣鞋(xie)（靴）使用注意(yi)事項

一、應根據作(zuo)業場所電(dian)壓(ya)(ya)高(gao)低(di)正(zheng)確選(xuan)用(yong)(yong)(yong)絕緣鞋(xie)，低(di)壓(ya)(ya)絕緣鞋(xie)禁止在高(gao)壓(ya)(ya)電(dian)氣(qi)設備(bei)上(shang)(shang)作(zuo)為(wei)安全輔助(zhu)用(yong)(yong)(yong)具使(shi)(shi)用(yong)(yong)(yong)，高(gao)壓(ya)(ya)絕緣鞋(xie)（靴）可以(yi)作(zuo)為(wei)高(gao)壓(ya)(ya)和低(di)壓(ya)(ya)電(dian)氣(qi)設備(bei)上(shang)(shang)輔助(zhu)安全用(yong)(yong)(yong)具使(shi)(shi)用(yong)(yong)(yong)。但 不論是穿低(di)壓(ya)(ya)或高(gao)壓(ya)(ya)絕緣鞋(xie)（靴），均不得直接(jie)用(yong)(yong)(yong)手接(jie)觸(chu)電(dian)氣(qi)設備(bei)。

二、布面絕緣鞋只能(neng)在干(gan)燥環境下使用，避(bi)免(mian)布面潮濕。 　　

三、絕緣鞋（靴(xue)）的使(shi)用(yong)不可有破損。 　　

四、穿用(yong)絕緣靴(xue)時，應將(jiang)褲管套入靴(xue)簡(jian)內。穿用(yong)絕緣鞋時，褲管不宜長(chang)及(ji)鞋底外(wai)沿條高度(du)，更不能長(chang)及(ji)地面，保持布幫干燥。 　　

五、非耐酸堿油的橡膠底，不可與酸堿油類物物質接觸，并應防止尖銳物刺傷。低壓(ya)絕緣鞋若底花紋(wen)磨光，露(lu)出內部顏色(se)時則不能作(zuo)為絕緣鞋使用。 　　

六、在購買絕緣鞋(xie)（靴）時(shi)，應查驗鞋(xie)上是否(fou)有絕緣*標記，如(ru)紅色閃電(dian)符(fu)號(hao)，鞋(xie)底有耐電(dian)壓多少優，等表示；鞋(xie)內有否(fou)合格證(zheng)，安全鑒定證(zheng)，生(sheng)產許可證(zheng)編(bian)號(hao)等。
