20KV耐電弧試驗儀廠家耐電弧性

塑料材料抵抗由高壓電(dian)弧作(zuo)用引起(qi)變質的能(neng)力，通常(chang)用電(dian)弧焰在材料表(biao)面引起(qi)碳(tan)化至表(biao)面所需的時間表(biao)示。

定義(yi)
電弧是一種(zhong)氣體放電現(xian)象，電流通(tong)過某些絕緣(yuan)介質(例(li)如空氣)所產(chan)生的(de)瞬間火花。

 分(fen)類
<1>;按電電弧噴金(jin)屬防腐流種(zhong)類(lei)可分(fen)為：交(jiao)流電弧、直流電弧和脈(mo)沖電弧。  

<2>按電弧(hu)的狀態(tai)可分(fen)為：自由電弧(hu)和壓縮電弧(hu)（如等(deng)離子弧(hu)）。 &nbsp;

<3>按電(dian)極材料可分(fen)為：熔化(hua)極電(dian)弧(hu)和不(bu)熔化(hua)極電(dian)弧(hu)。

 作用
電弧是高(gao)溫高(gao)導(dao)電率的游離氣體，它不(bu)僅對觸頭(tou)有很(hen)大的破壞作用，而且使斷開電路的時間延長。

產(chan)生
電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)當用開(kai)關(guan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器斷(duan)開(kai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流時(shi)(shi)，如果(guo)(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓不低于10—20伏，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流不小于80~100mA，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)觸(chu)頭(tou)(tou)間(jian)便(bian)會(hui)產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)。   因此(ci)，在(zai)了解(jie)開(kai)關(guan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)(de)結構和工作情況之前(qian)，首先(xian)來看看其(qi)是(shi)如何產生和熄滅的(de)(de)。   電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)的(de)(de)形成(cheng)是(shi)觸(chu)頭(tou)(tou)間(jian)中(zhong)(zhong)性質子(zi)(zi)(zi)(zi)(zi)(zi)(分子(zi)(zi)(zi)(zi)(zi)(zi)和原子(zi)(zi)(zi)(zi)(zi)(zi))被游(you)(you)離(li)(li)(li)(li)的(de)(de)過程(cheng)。開(kai)關(guan)觸(chu)頭(tou)(tou)分離(li)(li)(li)(li)時(shi)(shi)，觸(chu)頭(tou)(tou)間(jian)距離(li)(li)(li)(li)很小，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)強度(du)E很高(gao)(E = U/d)。當電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)強度(du)超過3×10^6V/m時(shi)(shi)，陰極(ji)表面的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)就(jiu)會(hui)被電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)拉出而(er)(er)形成(cheng)觸(chu)頭(tou)(tou)空(kong)間(jian)的(de)(de)自由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)。這(zhe)(zhe)(zhe)種游(you)(you)離(li)(li)(li)(li)方式稱為(wei)：強電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)發(fa)射(she)。   從(cong)陰極(ji)表面發(fa)射(she)出來的(de)(de)自由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)和觸(chu)頭(tou)(tou)間(jian)原有(you)的(de)(de)少(shao)數電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)，在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)力(li)的(de)(de)作用下向(xiang)(xiang)陽極(ji)作加(jia)(jia)速(su)運(yun)動(dong)，途中(zhong)(zhong)不斷(duan)地和中(zhong)(zhong)性質點相碰撞。只要電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)的(de)(de)運(yun)動(dong)速(su)度(du)v足(zu)(zu)夠(gou)高(gao)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)的(de)(de)動(dong)能A=1/2mv^2足(zu)(zu)夠(gou)大，就(jiu)可(ke)能從(cong)中(zhong)(zhong)性質子(zi)(zi)(zi)(zi)(zi)(zi)中(zhong)(zhong)打出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)，形成(cheng)自由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)和正(zheng)(zheng)離(li)(li)(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)。這(zhe)(zhe)(zhe)種現象(xiang)稱為(wei)碰撞游(you)(you)離(li)(li)(li)(li)。新(xin)形成(cheng)的(de)(de)自由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)也向(xiang)(xiang)陽極(ji)作加(jia)(jia)速(su)運(yun)動(dong)，同樣地會(hui)與中(zhong)(zhong)性質點碰撞而(er)(er)發(fa)生游(you)(you)離(li)(li)(li)(li)。碰撞游(you)(you)離(li)(li)(li)(li)連(lian)續進行的(de)(de)結果(guo)(guo)是(shi)觸(chu)頭(tou)(tou)間(jian)充(chong)滿了電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)和正(zheng)(zheng)離(li)(li)(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)，具有(you)很大的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)導；在(zai)外加(jia)(jia)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓下，介(jie)質被擊穿而(er)(er)產生電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路再次被導通。   觸(chu)頭(tou)(tou)間(jian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)燃燒的(de)(de)間(jian)隙(xi)稱為(wei)弧(hu)(hu)(hu)隙(xi)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)形成(cheng)后，弧(hu)(hu)(hu)隙(xi)間(jian)的(de)(de)高(gao)溫使(shi)陰極(ji)表面的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)獲得足(zu)(zu)夠(gou)的(de)(de)能量而(er)(er)向(xiang)(xiang)外發(fa)射(she)，形成(cheng)熱電(dian)(dian)(dian)(dian)(dian)(dian)(dian)場(chang)發(fa)射(she)。同時(shi)(shi)在(zai)高(gao)溫的(de)(de)作用下(電(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)(hu)中(zhong)(zhong)心(xin)部分維(wei)持的(de)(de)溫度(du)可(ke)達10000℃以(yi)上(shang))，氣體中(zhong)(zhong)性質點的(de)(de)不規則熱運(yun)動(dong)速(su)度(du)增加(jia)(jia)。當具有(you)足(zu)(zu)夠(gou)動(dong)能的(de)(de)中(zhong)(zhong)性質點相互碰撞時(shi)(shi)，將被游(you)(you)離(li)(li)(li)(li)而(er)(er)形成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)(zi)(zi)(zi)和正(zheng)(zheng)離(li)(li)(li)(li)子(zi)(zi)(zi)(zi)(zi)(zi)，這(zhe)(zhe)(zhe)種現象(xiang)稱為(wei)熱游(you)(you)離(li)(li)(li)(li)。

隨著觸頭分(fen)開的距離(li)增大，觸頭間(jian)的電(dian)(dian)場強度(du)E逐(zhu)漸減(jian)(jian)小，這時電(dian)(dian)弧的燃(ran)燒(shao)主要(yao)是依靠熱游(you)(you)離(li)維持的。   在(zai)開關電(dian)(dian)器的觸頭間(jian)，發生游(you)(you)離(li)過(guo)程的同時，還(huan)發生著使帶電(dian)(dian)質點減(jian)(jian)少的去游(you)(you)離(li)過(guo)程。
