真空断路器的原理

真(zhen)(zhen)空(kong)断路(lu)器(qi)部件(jian)真(zhen)(zhen)空(kong)灭(mie)(mie)弧(hu)(hu)室(shi)是利(li)用高(gao)真(zhen)(zhen)空(kong)度(du)(du)绝(jue)缘(yuan)灭(mie)(mie)弧(hu)(hu)介质，用密封(feng)在(zai)真(zhen)(zhen)空(kong)中的(de)(de)(de)(de)一(yi)(yi)对触头(tou)来实现电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)通断功能的(de)(de)(de)(de)一(yi)(yi)种电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)真(zhen)(zhen)空(kong)器(qi)件(jian)。当其断开(kai)一(yi)(yi)定数值的(de)(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)时(shi)，动静触头(tou)在(zai)分离(li)的(de)(de)(de)(de)瞬间(jian)(jian)，电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)收缩(suo)到触头(tou)刚分离(li)的(de)(de)(de)(de)某一(yi)(yi)点或某几点上，导(dao)(dao)致电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)极间(jian)(jian)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻剧(ju)烈增大和温度(du)(du)迅速(su)提(ti)高(gao)，直(zhi)至发生电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)极金属(shu)的(de)(de)(de)(de)蒸发，同(tong)(tong)时(shi)形成极高(gao)的(de)(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)场强度(du)(du)，导(dao)(dao)致剧(ju)烈的(de)(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)场强发射和间(jian)(jian)隙(xi)击穿，产生真(zhen)(zhen)空(kong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)。当工作电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)接近零时(shi)，同(tong)(tong)时(shi)触头(tou)间(jian)(jian)距(ju)的(de)(de)(de)(de)增大，真(zhen)(zhen)空(kong)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)的(de)(de)(de)(de)离(li)子体(ti)很(hen)快(kuai)向四周扩(kuo)散，电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)过(guo)零后，触头(tou)间(jian)(jian)隙(xi)的(de)(de)(de)(de)介质迅速(su)由导(dao)(dao)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)体(ti)变为绝(jue)缘(yuan)体(ti)，于是电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)被(bei)分断。由于触头(tou)的(de)(de)(de)(de)特殊构造，燃弧(hu)(hu)期间(jian)(jian)触头(tou)间(jian)(jian)隙(xi)会(hui)产适当的(de)(de)(de)(de)纵向磁场，这个磁场可使电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)均匀分布(bu)在(zai)触头(tou)表面，维持低(di)的(de)(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)压，从而使真(zhen)(zhen)空(kong)灭(mie)(mie)弧(hu)(hu)室(shi)具有较高(gao)的(de)(de)(de)(de)弧(hu)(hu)后介质强度(du)(du)恢复速(su)度(du)(du)、小(xiao)的(de)(de)(de)(de)电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)弧(hu)(hu)能量和小(xiao)的(de)(de)(de)(de)腐蚀(shi)速(su)率。这样，就提(ti)高(gao)了(le)真(zhen)(zhen)空(kong)灭(mie)(mie)弧(hu)(hu)室(shi)开(kai)断电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)能力和使用寿命。重庆预付(fu)费真(zhen)(zhen)空(kong)断路(lu)器(qi)价(jia)格真(zhen)(zhen)空(kong)断路(lu)器(qi)设备(bei)，就选浙江豫峰电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)气有限公司，欢迎客户来电(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)！
