真空開(kai)關(guan)的組成(cheng)和工作過(guo)程

真空(kong)(kong)開(kai)(kai)關(guan)的組(zu)成真空(kong)(kong)開(kai)(kai)關(guan)是由觸頭、靜觸頭、真空(kong)(kong)瓶(ping)、開(kai)(kai)閉機(ji)構、彈(dan)簧、密封件等組(zu)成。其中(zhong)真空(kong)(kong)瓶(ping)是真空(kong)(kong)主斷(duan)路(lu)(lu)器(qi)(qi)的部件。2. 真空(kong)(kong)開(kai)(kai)關(guan)的工(gong)作(zuo)過程(cheng)當(dang)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)中(zhong)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流超過真空(kong)(kong)主斷(duan)路(lu)(lu)器(qi)(qi)的額定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流時，真空(kong)(kong)瓶(ping)中(zhong)的真空(kong)(kong)擊穿(chuan)。真空(kong)(kong)中(zhong)的自由電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)大(da)量(liang)產生(sheng)，形(xing)成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)云，導致電(dian)(dian)(dian)(dian)(dian)(dian)(dian)平降低(di)，從而引起觸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)螺旋的弧(hu)(hu)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)會使(shi)得弧(hu)(hu)道內的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)受(shou)到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)作(zuo)用(yong)，形(xing)成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)漩渦。弧(hu)(hu)道內的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)離程(cheng)度(du)越來(lai)越大(da)，橄欖形(xing)區域內電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子(zi)(zi)(zi)能(neng)量(liang)越來(lai)越高，使(shi)得橄欖形(xing)區域完全(quan)離子(zi)(zi)(zi)化，磁場產生(sheng)將(jiang)磁力(li)線堆緊，弧(hu)(hu)道被截斷(duan)，從而切斷(duan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)中(zhong)的電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流。真空(kong)(kong)斷(duan)路(lu)(lu)器(qi)(qi)設備，就選浙江豫峰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)氣有限公司，歡迎客戶來(lai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)！河南預付(fu)費真空(kong)(kong)斷(duan)路(lu)(lu)器(qi)(qi)哪(na)種好
