防(fang)爆磁力啟動(dong)器你了解多少(shao)？

防(fang)爆磁力(li)啟動(dong)(dong)(dong)器由鋼(gang)質沖(chong)壓外殼(ke)、鋼(gang)制地板(ban)、交流(liu)接(jie)(jie)(jie)觸(chu)(chu)器、熱(re)繼(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器和相應(ying)配線(xian)構成，使(shi)用(yong)時(shi)(shi)應(ying)配用(yong)啟動(dong)(dong)(dong)停(ting)止(zhi)按(an)鈕(niu)開(kai)(kai)關，并正確(que)連接(jie)(jie)(jie)手控信號電(dian)(dian)(dian)(dian)(dian)(dian)(dian)纜。當按(an)下(xia)啟動(dong)(dong)(dong)按(an)鈕(niu)時(shi)(shi)，防(fang)爆磁力(li)啟動(dong)(dong)(dong)器內裝的交流(liu)接(jie)(jie)(jie)觸(chu)(chu)器線(xian)圈(quan)得電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，銜鐵帶動(dong)(dong)(dong)觸(chu)(chu)點組閉合(he)，接(jie)(jie)(jie)通用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(一般為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，同(tong)時(shi)(shi)通過輔助觸(chu)(chu)點自鎖。按(an)下(xia)停(ting)止(zhi)按(an)鈕(niu)時(shi)(shi)，內部(bu)交流(liu)接(jie)(jie)(jie)觸(chu)(chu)器線(xian)圈(quan)失電(dian)(dian)(dian)(dian)(dian)(dian)(dian)，觸(chu)(chu)點斷(duan)開(kai)(kai)，切斷(duan)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)器電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)并解(jie)鎖。

防爆(bao)磁力啟動器(qi)采用(yong)復(fu)合型，模塊結構(gou)，各回路(lu)可(ke)根(gen)據 需要自(zi)由(you)組裝，一般開(kai)關(guan)箱采用(yong)隔爆(bao)型結構(gou)，母(mu)線(xian)箱及出線(xian)箱采 用(yong)增安型結構(gou). 內(nei)裝交(jiao)流接觸器(qi)、熱繼電(dian)器(qi)、控制(zhi)按鈕或開(kai)關(guan)，也(ye)可(ke)在箱面或遠 程操作(zuo)，也(ye)可(ke)兩地操作(zuo)，具有分斷、過(guo)載(zai)、失壓保護(hu)和短路(lu)自(zi)動 切斷功能。

防爆磁力啟動(dong)器(qi)屬(shu)于(yu)(yu)全(quan)壓直接起動(dong)，在電網容量(liang)和(he)負(fu)載兩方(fang)面都允許全(quan)壓直接起動(dong)的情(qing)況(kuang)下使用。優(you)點(dian)是操縱(zong)控制方(fang)便(bian)，維護(hu)簡單，而且(qie)比(bi)較經濟。主要用于(yu)(yu)小功率電動(dong)機(ji)的起動(dong)，大于(yu)(yu)11kw的電動(dong)機(ji)不宜用此方(fang)法。
