注意事項:

三(san)種(zhong)聲(sheng)音(yin)做耐(nai)(nai)壓(ya)試驗時,由于電(dian)(dian)(dian)(dian)(dian)氣(qi)(qi)距離(li)的(de)(de)(de)原因(yin)會有三(san)種(zhong)聲(sheng)音(yin)“噼(pi)啪(pa)噼(pi)啪(pa)":是(shi)空(kong)(kong)(kong)(kong)氣(qi)(qi)電(dian)(dian)(dian)(dian)(dian)離(li)的(de)(de)(de)聲(sheng)音(yin)“zi,zi":是(shi)空(kong)(kong)(kong)(kong)氣(qi)(qi)流(liu)(liu)注的(de)(de)(de)聲(sheng)音(yin)“啪(pa)":又響又脆,伴隨火花,是(shi)絕(jue)緣(yuan)(或(huo)空(kong)(kong)(kong)(kong)氣(qi)(qi))被(bei)擊穿的(de)(de)(de)聲(sheng)音(yin)一般,空(kong)(kong)(kong)(kong)氣(qi)(qi)放(fang)電(dian)(dian)(dian)(dian)(dian)分(fen)三(san)階段(duan)(duan),階段(duan)(duan)是(shi)電(dian)(dian)(dian)(dian)(dian)離(li),電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)在(zai)大點(dian),就(jiu)會進入流(liu)(liu)注階段(duan)(duan),在(zai)大點(dian)空(kong)(kong)(kong)(kong)氣(qi)(qi)就(jiu)會被(bei)擊穿。耐(nai)(nai)壓(ya)噪(zao)聲(sheng)大的(de)(de)(de)主(zhu)(zhu)要(yao)(yao)原因(yin)是(shi)主(zhu)(zhu)空(kong)(kong)(kong)(kong)道(dao)(dao)(高壓(ya)線(xian)圈與(yu)低壓(ya)線(xian)圈)的(de)(de)(de)空(kong)(kong)(kong)(kong)氣(qi)(qi)距離(li)不夠(gou)。E=U/D E電(dian)(dian)(dian)(dian)(dian)場(chang)(chang),U電(dian)(dian)(dian)(dian)(dian)壓(ya),D電(dian)(dian)(dian)(dian)(dian)極間的(de)(de)(de)距離(li),當(dang)D較小時,E較大,空(kong)(kong)(kong)(kong)氣(qi)(qi)在(zai)標準氣(qi)(qi)壓(ya),標準濕度下(xia)耐(nai)(nai)受(shou)場(chang)(chang)強大致為0.7KV/mm。當(dang)電(dian)(dian)(dian)(dian)(dian)場(chang)(chang)大于這個值(zhi)時,分(fen)子(zi)就(jiu)會容易電(dian)(dian)(dian)(dian)(dian)離(li)。但是(shi)只要(yao)(yao)空(kong)(kong)(kong)(kong)氣(qi)(qi)不被(bei)擊穿,就(jiu)不會導電(dian)(dian)(dian)(dian)(dian)。順便說(shuo)一下(xia),變壓(ya)器主(zhu)(zhu)空(kong)(kong)(kong)(kong)道(dao)(dao)的(de)(de)(de)絕(jue)緣(yuan)不要(yao)(yao)只看空(kong)(kong)(kong)(kong)氣(qi)(qi),因(yin)為高低壓(ya)線(xian)圈也有內外層(ceng)絕(jue)緣(yuan),計(ji)算(suan)時,應以復合(he)絕(jue)緣(yuan)考(kao)慮。
