真空斷路器的部件中觸頭結(jié)構(gòu)大致有三種：圓柱形觸頭、帶有螺旋槽跑弧面的橫向磁場(chǎng)觸頭、縱向磁場(chǎng)觸頭。目前采用縱磁場(chǎng)技術(shù)，此種滅弧室具有強(qiáng)而穩(wěn)定的電弧開(kāi)斷能力。屏蔽系統(tǒng)，屏蔽罩是真空滅弧室中不可缺少的元件，并且有圍繞觸頭的主屏蔽罩、波紋管屏蔽罩和均壓用屏蔽罩等多種。主屏蔽罩的作用是：防止燃弧過(guò)程中電弧生成物噴濺到絕緣外殼的內(nèi)壁，從而降低外殼的絕緣強(qiáng)度。改善滅弧室內(nèi)部電場(chǎng)分布的均勻性，有利于降低局部場(chǎng)強(qiáng)，促進(jìn)真空滅弧室小型化。冷凝電弧生成物，吸收一部分電弧能量，有助于弧后間隙介質(zhì)強(qiáng)度的恢復(fù)。

style="text-indent:25px">真空斷路器的特點(diǎn)：觸頭開(kāi)距小，10KV真空斷路器的觸頭開(kāi)距只有10mm左右，操作機(jī)構(gòu)的操作功就小，機(jī)械部分行程小，其機(jī)械壽命就長(zhǎng)。燃弧時(shí)間短，且與開(kāi)關(guān)電流大小無(wú)關(guān)，一般只有半周波。熄弧后觸頭間隙介質(zhì)恢復(fù)速度快，對(duì)開(kāi)斷近區(qū)故障性能較好。由于觸頭在開(kāi)斷電流時(shí)磨損量較小，所以觸頭的電氣壽命長(zhǎng)，滿(mǎn)容量開(kāi)斷達(dá)30-50次，額定電流開(kāi)斷達(dá)5000次以上，噪音小適于頻繁操作。體積小、重量輕。適用于開(kāi)斷容性負(fù)荷電流。由于其優(yōu)點(diǎn)很多，所以多應(yīng)用于變電站中。關(guān)于真空斷路器你了解多少？</p><div
