20KV耐電弧試驗儀廠家耐電弧性

塑料材(cai)料抵抗由高壓電弧作用(yong)引(yin)起(qi)變質的能力，通常用(yong)電弧焰在材(cai)料表面引(yin)起(qi)碳化(hua)至表面所需(xu)的時間(jian)表示。

定義
電(dian)(dian)弧是一種氣(qi)體(ti)放電(dian)(dian)現(xian)象，電(dian)(dian)流通過某些(xie)絕緣介(jie)質(例(li)如(ru)空氣(qi))所產生(sheng)的(de)瞬間火花。

 分類(lei)
<;1>按電(dian)電(dian)弧噴金屬防腐流(liu)種(zhong)類(lei)可分為：交流(liu)電(dian)弧、直流(liu)電(dian)弧和(he)脈沖電(dian)弧。  

<2>按電弧的狀態可分為(wei)：自由(you)電弧和壓縮電弧（如(ru)等(deng)離子弧）。 &nbsp;

<3>按電(dian)極材料(liao)可(ke)分為：熔化極電(dian)弧和不熔化極電(dian)弧。

 作用
電(dian)弧是(shi)高溫(wen)高導電(dian)率的(de)游離氣體，它不僅對觸(chu)頭(tou)有很大的(de)破壞作用(yong)，而且使斷開電(dian)路(lu)的(de)時間(jian)延長。

產生
電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)當(dang)用開(kai)(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器斷開(kai)(kai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流時，如(ru)果電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)不低(di)于10—20伏，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流不小(xiao)于80~100mA，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)(de)觸頭間(jian)便會產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)。   因(yin)此，在(zai)了解開(kai)(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)(de)結構和(he)(he)工作(zuo)情況之前，首先來(lai)看(kan)看(kan)其是(shi)如(ru)何產生和(he)(he)熄滅(mie)的(de)(de)(de)。   電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)的(de)(de)(de)形(xing)(xing)成(cheng)是(shi)觸頭間(jian)中(zhong)性(xing)質(zhi)(zhi)子(zi)(zi)(zi)(zi)(zi)(分子(zi)(zi)(zi)(zi)(zi)和(he)(he)原(yuan)子(zi)(zi)(zi)(zi)(zi))被(bei)游(you)(you)離(li)的(de)(de)(de)過程。開(kai)(kai)關觸頭分離(li)時，觸頭間(jian)距離(li)很(hen)小(xiao)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)強(qiang)度E很(hen)高(gao)(E = U/d)。當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)強(qiang)度超過3×10^6V/m時，陰極(ji)表面的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)就會被(bei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力拉出(chu)而(er)(er)形(xing)(xing)成(cheng)觸頭空間(jian)的(de)(de)(de)自(zi)由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)。這種(zhong)游(you)(you)離(li)方式稱(cheng)為：強(qiang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)發射(she)。   從(cong)(cong)陰極(ji)表面發射(she)出(chu)來(lai)的(de)(de)(de)自(zi)由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)和(he)(he)觸頭間(jian)原(yuan)有(you)(you)的(de)(de)(de)少數電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)，在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力的(de)(de)(de)作(zuo)用下(xia)向陽極(ji)作(zuo)加速運(yun)(yun)動(dong)(dong)，途(tu)中(zhong)不斷地和(he)(he)中(zhong)性(xing)質(zhi)(zhi)點(dian)相碰撞。只要電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)的(de)(de)(de)運(yun)(yun)動(dong)(dong)速度v足夠(gou)高(gao)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)的(de)(de)(de)動(dong)(dong)能A=1/2mv^2足夠(gou)大(da)，就可能從(cong)(cong)中(zhong)性(xing)質(zhi)(zhi)子(zi)(zi)(zi)(zi)(zi)中(zhong)打出(chu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)，形(xing)(xing)成(cheng)自(zi)由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)和(he)(he)正離(li)子(zi)(zi)(zi)(zi)(zi)。這種(zhong)現(xian)象稱(cheng)為碰撞游(you)(you)離(li)。新形(xing)(xing)成(cheng)的(de)(de)(de)自(zi)由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)也向陽極(ji)作(zuo)加速運(yun)(yun)動(dong)(dong)，同(tong)(tong)樣地會與(yu)中(zhong)性(xing)質(zhi)(zhi)點(dian)碰撞而(er)(er)發生游(you)(you)離(li)。碰撞游(you)(you)離(li)連續進行的(de)(de)(de)結果是(shi)觸頭間(jian)充滿(man)了電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)和(he)(he)正離(li)子(zi)(zi)(zi)(zi)(zi)，具有(you)(you)很(hen)大(da)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)導；在(zai)外加電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)下(xia)，介質(zhi)(zhi)被(bei)擊穿而(er)(er)產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路再次被(bei)導通。   觸頭間(jian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)燃燒的(de)(de)(de)間(jian)隙(xi)(xi)稱(cheng)為弧(hu)(hu)(hu)隙(xi)(xi)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)形(xing)(xing)成(cheng)后，弧(hu)(hu)(hu)隙(xi)(xi)間(jian)的(de)(de)(de)高(gao)溫使陰極(ji)表面的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)獲得足夠(gou)的(de)(de)(de)能量而(er)(er)向外發射(she)，形(xing)(xing)成(cheng)熱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)發射(she)。同(tong)(tong)時在(zai)高(gao)溫的(de)(de)(de)作(zuo)用下(xia)(電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)中(zhong)心部分維持的(de)(de)(de)溫度可達10000℃以上)，氣體中(zhong)性(xing)質(zhi)(zhi)點(dian)的(de)(de)(de)不規則熱運(yun)(yun)動(dong)(dong)速度增加。當(dang)具有(you)(you)足夠(gou)動(dong)(dong)能的(de)(de)(de)中(zhong)性(xing)質(zhi)(zhi)點(dian)相互碰撞時，將被(bei)游(you)(you)離(li)而(er)(er)形(xing)(xing)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)和(he)(he)正離(li)子(zi)(zi)(zi)(zi)(zi)，這種(zhong)現(xian)象稱(cheng)為熱游(you)(you)離(li)。

隨著觸頭分開的(de)距離(li)增大，觸頭間的(de)電(dian)場強度E逐漸減小，這時(shi)(shi)電(dian)弧的(de)燃燒主要是依(yi)靠熱(re)游(you)(you)離(li)維持的(de)。   在開關電(dian)器的(de)觸頭間，發生游(you)(you)離(li)過程的(de)同(tong)時(shi)(shi)，還發生著使帶電(dian)質點減少的(de)去游(you)(you)離(li)過程。
