真空接(jie)觸(chu)器(qi)主要由真空滅弧室(shi)和操作機構組成。真空滅弧室(shi)具有(you)通(tong)過正(zheng)常工(gong)作電(dian)流和頻(pin)繁切斷工(gong)作電(dian)流時可靠(kao)滅弧兩(liang)個作用。但(dan)不能切斷過負荷電(dian)流和短路(lu)電(dian)流。操作機構是由帶(dai)鐵(tie)(tie)芯(xin)的吸(xi)(xi)持(chi)線(xian)圈和銜鐵(tie)(tie)構成。線(xian)圈通(tong)電(dian)，吸(xi)(xi)引銜鐵(tie)(tie)，接(jie)觸(chu)器(qi)閉(bi)合；線(xian)圈失電(dian)，接(jie)觸(chu)器(qi)斷開。吸(xi)(xi)持(chi)線(xian)圈一(yi)般(ban)有(you)直流和交流兩(liang)種形(xing)式。

真空滅弧(hu)室(shi)的(de)外殼用(yong)玻(bo)璃或陶瓷絕緣(yuan)材料制成，內部的(de)真空度通(tong)常(chang)在0.01Pa以上。由(you)于(yu)殼內的(de)空氣少，觸頭(tou)開距可以做得很(hen)小，電弧(hu)也較容易被(bei)熄(xi)滅。觸頭(tou)材料一般用(yong)銅、銻、鋨等合金制成。滅弧(hu)

室內屏(ping)蔽罩的作用(yong)(yong)是，當分(fen)斷電流時(shi)，凝結觸(chu)頭間(jian)隙中擴散出來的金(jin)屬蒸汽(qi)，有(you)助于熄弧，還可以防(fang)止(zhi)金(jin)屬蒸汽(qi)濺落(luo)到絕緣外(wai)殼(ke)上降低其(qi)絕緣強(qiang)度。動(dong)觸(chu)頭與外(wai)殼(ke)下端用(yong)(yong)波紋管連接，動(dong)觸(chu)頭可以上下運動(dong)又(you)不會漏汽(qi)。

防電磁干擾：稀土永磁直流接觸器應用的永磁材料等效電路是密封性的，，在應用全過程中不容易遭受外界電磁干擾，也不會對外界開展電磁干擾[2]。智能化防晃電：控制電子器件控制模塊控制設置的釋放工作電壓值，可延遲時間一定時間再傳出反方向浪涌電流以做到低壓廷時釋放或關閉電源廷時釋放，使其控制的電機免遭電網工作電壓起伏(晃電)而跳停，進而維持生產系統的平穩。尤其是設備型持續生產的公司，可降低放空自己和恢復生產的電、蒸氣、燃氣耗費和人工費用、機器設備毀壞維修費等。
