首先(xian)，让我们简(jian)单介绍(shao)一(yi)下(xia)电(dian)(dian)(dian)弧(hu)及其危害(hai)。电(dian)(dian)(dian)弧(hu)是一(yi)种放(fang)电(dian)(dian)(dian)和高温发光现象，通(tong)(tong)过(guo)缝(feng)隙或(huo)某些(xie)介质如烧(shao)(shao)焦的(de)(de)绝(jue)缘(yuan)材料(liao)。电(dian)(dian)(dian)弧(hu)的(de)(de)危害(hai)是由电(dian)(dian)(dian)弧(hu)释放(fang)的(de)(de)能(neng)量引(yin)起(qi)的(de)(de)。电(dian)(dian)(dian)弧(hu)发生时，会在(zai)瞬间释放(fang)出巨(ju)大(da)的(de)(de)能(neng)量，往(wang)(wang)往(wang)(wang)会产生2000多度的(de)(de)高温，造(zao)成强烈的(de)(de)瓦斯爆(bao)炸和电(dian)(dian)(dian)烧(shao)(shao)伤。这(zhei)种危险(xian)通(tong)(tong)常不同于其他(ta)电(dian)(dian)(dian)气(qi)伤害(hai)。它往(wang)(wang)往(wang)(wang)没有必要去碰，但也容(rong)易被忽视，难(nan)以避免。电(dian)(dian)(dian)弧(hu)会直(zhi)接接触被点燃的(de)(de)衣物(wu)，造(zao)成严重(zhong)烧(shao)(shao)伤或(huo)人员死亡。通(tong)(tong)常，人们对意外(wai)触电(dian)(dian)(dian)的(de)(de)认(ren)识比较(jiao)多，但事(shi)实上，在(zai)电(dian)(dian)(dian)力行业中(zhong)，电(dian)(dian)(dian)弧(hu)危害(hai)一(yi)直(zhi)是电(dian)(dian)(dian)力工作者面临和隐藏的(de)(de)一(yi)种隐患。

电(dian)(dian)弧(hu)防(fang)(fang)(fang)(fang)护服(fu)(fu)(fu)(fu)的(de)主(zhu)(zhu)要(yao)功(gong)能(neng)(neng)(neng)是在(zai)(zai)可能(neng)(neng)(neng)存(cun)在(zai)(zai)电(dian)(dian)弧(hu)危(wei)害(hai)的(de)环境中提供安(an)全防(fang)(fang)(fang)(fang)护。主(zhu)(zhu)要(yao)应用于变(bian)电(dian)(dian)站、供电(dian)(dian)站、大型电(dian)(dian)力(li)运行设备(bei)等电(dian)(dian)力(li)行业(ye)。  防(fang)(fang)(fang)(fang)电(dian)(dian)弧(hu)服(fu)(fu)(fu)(fu)有(you)“三紧式”和(he)“大袍式”。所有(you)表面附件(jian)均采用本征阻(zu)燃(ran)材料，不会因反复(fu)洗涤而(er)降(jiang)低防(fang)(fang)(fang)(fang)护性能(neng)(neng)(neng)。它不会被(bei)热能(neng)(neng)(neng)点(dian)燃(ran)而(er)继续燃(ran)烧，也(ye)不会产生熔化和(he)滴落。防(fang)(fang)(fang)(fang)电(dian)(dian)弧(hu)服(fu)(fu)(fu)(fu)采用性阻(zu)燃(ran)缝纫线，钢丝(si)的(de)断(duan)裂强度(du)优于阻(zu)燃(ran)服(fu)(fu)(fu)(fu)标准。防(fang)(fang)(fang)(fang)电(dian)(dian)弧(hu)服(fu)(fu)(fu)(fu)具有(you)防(fang)(fang)(fang)(fang)电(dian)(dian)弧(hu)、阻(zu)燃(ran)、隔热、透气、舒适等性能(neng)(neng)(neng)。为了增加夜间(jian)和(he)光线不足环境中工人的(de)能(neng)(neng)(neng)见度(du)和(he)警示功(gong)能(neng)(neng)(neng)，一般(ban)在(zai)(zai)防(fang)(fang)(fang)(fang)电(dian)(dian)弧(hu)服(fu)(fu)(fu)(fu)上(shang)加3M阻(zu)燃(ran)反光带。防(fang)(fang)(fang)(fang)弧(hu)服(fu)(fu)(fu)(fu)与防(fang)(fang)(fang)(fang)弧(hu)手套(tao)、头盔、防(fang)(fang)(fang)(fang)弧(hu)鞋套(tao)配合使(shi)用，防(fang)(fang)(fang)(fang)护效果更好(hao)。在(zai)(zai)使(shi)用防(fang)(fang)(fang)(fang)弧(hu)服(fu)(fu)(fu)(fu)之前，应根据作业(ye)环境的(de)潜(qian)在(zai)(zai)危(wei)险程度(du)选(xuan)择合适级别(bie)的(de)防(fang)(fang)(fang)(fang)弧(hu)服(fu)(fu)(fu)(fu)。
