啟動繼電器的作用_電磁繼電器工作原理
什么是(shi)啟動繼電器(qi)
啟動(dong)(dong)(dong)(dong)繼電(dian)(dian)器(qi)(qi)是(shi)采用單相(xiang)異(yi)步電(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)的壓(ya)(ya)縮機(ji)啟動(dong)(dong)(dong)(dong)專用元件。啟動(dong)(dong)(dong)(dong)繼電(dian)(dian)器(qi)(qi)是(shi)單獨部件，其作用是(shi)接通、斷開(kai)吸(xi)引線(xian)圈(quan)和保持線(xian)圈(quan)電(dian)(dian)路。在(zai)電(dian)(dian)冰(bing)箱、空調(diao)器(qi)(qi)這類小型制冷(leng)設備中，制冷(leng)壓(ya)(ya)縮機(ji)多采用單相(xiang)分相(xiang)式(shi)異(yi)步電(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)，啟動(dong)(dong)(dong)(dong)繼電(dian)(dian)器(qi)(qi)的作用是(shi)幫助電(dian)(dian)動(dong)(dong)(dong)(dong)機(ji)啟動(dong)(dong)(dong)(dong)，啟動(dong)(dong)(dong)(dong)完成后自動(dong)(dong)(dong)(dong)斷開(kai)副繞(rao)組(zu)，避免(mian)燒(shao)壞(huai)副繞(rao)組(zu)線(xian)圈(quan)。
啟(qi)(qi)動(dong)(dong)(dong)繼電(dian)(dian)(dian)器(qi)是(shi)單相分(fen)相式(shi)感應電(dian)(dian)(dian)機(ji)實現自動(dong)(dong)(dong)啟(qi)(qi)動(dong)(dong)(dong)的控制元件。電(dian)(dian)(dian)冰箱(xiang)壓縮機(ji)啟(qi)(qi)動(dong)(dong)(dong)時(shi)，電(dian)(dian)(dian)機(ji)運行(xing)繞組通電(dian)(dian)(dian)；啟(qi)(qi)動(dong)(dong)(dong)結束轉入正(zheng)常(chang)運行(xing)時(shi)，啟(qi)(qi)動(dong)(dong)(dong)繼電(dian)(dian)(dian)器(qi)將(jiang)啟(qi)(qi)動(dong)(dong)(dong)繞組電(dian)(dian)(dian)源切斷。21世(shi)紀電(dian)(dian)(dian)冰箱(xiang)常(chang)用(yong)的啟(qi)(qi)動(dong)(dong)(dong)繼電(dian)(dian)(dian)器(qi)有(you)整(zheng)體式(shi)啟(qi)(qi)動(dong)(dong)(dong)繼電(dian)(dian)(dian)器(qi)、重(zhong)錘(chui)式(shi)啟(qi)(qi)動(dong)(dong)(dong)繼電(dian)(dian)(dian)器(qi)和VIE半(ban)導體啟(qi)(qi)動(dong)(dong)(dong)繼電(dian)(dian)(dian)器(qi)等(deng)幾種類型。
啟動繼電器(qi)的(de)作(zuo)用
主(zhu)要是通過(guo)控制(zhi)(zhi)低壓(ya)線路的(de)電(dian)流(liu)來(lai)控制(zhi)(zhi)高壓(ya)線路的(de)電(dian)流(liu)，起到(dao)電(dian)流(liu)開關的(de)作(zuo)用。啟動繼(ji)電(dian)器(qi)是啟動系(xi)統組成部(bu)件之(zhi)一，在汽(qi)車上主(zhu)要作(zuo)用為小(xiao)電(dian)流(liu)控制(zhi)(zhi)大電(dian)流(liu)方式啟動馬(ma)達轉(zhuan)動，從而帶(dai)動發(fa)電(dian)機內部(bu)磁電(dian)機轉(zhuan)子轉(zhuan)動，給點(dian)(dian)火(huo)器(qi)輸(shu)入(ru)點(dian)(dian)火(huo)脈沖信號，使點(dian)(dian)火(huo)器(qi)產(chan)生電(dian)火(huo)花，點(dian)(dian)燃汽(qi)缸(gang)內的(de)混合燃氣并(bing)做功(gong)。
繼電(dian)器屬于(yu)開關(guan)類(lei)，它是利用(yong)電(dian)磁原理、機(ji)電(dian)原理使(shi)接點閉合或(huo)斷開來驅動或(huo)控制(zhi)相關(guan)電(dian)路的(de)。
繼電(dian)器為(wei)一(yi)種控(kong)制(zhi)(zhi)器件，它(ta)有受控(kong)系統(tong)（輸(shu)入回(hui)路）和控(kong)制(zhi)(zhi)系統(tong)（輸(shu)出回(hui)路）兩部分。當(dang)輸(shu)入量（電(dian)、磁、光、熱等物理量）達到某一(yi)定值時，輸(shu)出量躍變(bian)(bian)式地由零變(bian)(bian)化到一(yi)定值（或由一(yi)定值跳(tiao)變(bian)(bian)到零），從而實現對電(dian)路的控(kong)制(zhi)(zhi)、保護、調節和傳遞信(xin)息等目(mu)的。
繼(ji)電器(qi)(qi)的(de)另一(yi)種定義：繼(ji)電器(qi)(qi)是當輸入量（或激勵(li)量）滿足某些規定條件時，能(neng)在(zai)一(yi)個(ge)或多個(ge)電氣輸出電路中(zhong)產生預定躍變的(de)一(yi)種器(qi)(qi)件。
電磁(ci)繼電器(qi)工作原(yuan)理
電磁式(shi)繼電器(qi)是繼電器(qi)中應用最(zui)早、最(zui)廣泛的一種(zhong)產品。
電(dian)(dian)(dian)(dian)磁(ci)式(shi)繼(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)主要由(you)電(dian)(dian)(dian)(dian)磁(ci)系(xi)統(tong)、返回系(xi)統(tong)等部分組成(cheng)。它(ta)由(you)電(dian)(dian)(dian)(dian)流(liu)繼(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)和電(dian)(dian)(dian)(dian)壓繼(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)2種結(jie)構形式(shi)。電(dian)(dian)(dian)(dian)流(liu)繼(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的(de)線圈與(yu)電(dian)(dian)(dian)(dian)源回路串聯(lian)，以電(dian)(dian)(dian)(dian)流(liu)為輸入量；電(dian)(dian)(dian)(dian)壓繼(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的(de)線圈與(yu)電(dian)(dian)(dian)(dian)源并聯(lian)，以電(dian)(dian)(dian)(dian)壓為輸入量。通常，電(dian)(dian)(dian)(dian)壓繼(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)使用(yong)較多。無線電(dian)(dian)(dian)(dian)設備用(yong)電(dian)(dian)(dian)(dian)磁(ci)繼(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)又可(ke)分為極化繼(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)和非極化繼(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)。極化繼(ji)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)在磁(ci)路內有(you)永久(jiu)磁(ci)鐵，銜鐵的(de)動(dong)作(zuo)具有(you)方向(xiang)性，隨著輸入量極性的(de)不(bu)同(tong)，銜鐵的(de)運動(dong)方向(xiang)也不(bu)同(tong)。
電磁(ci)繼電器的(de)工作原理(li)很簡單，它利用(yong)電磁(ci)感應原理(li)，當(dang)線(xian)圈(quan)中通過(guo)直流(liu)時，線(xian)圈(quan)產生磁(ci)場，動(dong)鐵(tie)(tie)被(bei)吸動(dong)帶(dai)動(dong)接(jie)(jie)觸簧片(pian)，使靜接(jie)(jie)點分開，動(dong)接(jie)(jie)點閉合。當(dang)電磁(ci)線(xian)圈(quan)電流(liu)被(bei)切斷(duan)后(hou)，鐵(tie)(tie)芯失去磁(ci)性，動(dong)鐵(tie)(tie)芯在彈簧力(li)的(de)作用(yong)下復(fu)位(wei)，動(dong)接(jie)(jie)點打開，靜接(jie)(jie)點閉合。
繼電(dian)器線圈在(zai)沒通(tong)電(dian)時處于斷開(kai)位置(zhi)的接(jie)(jie)(jie)(jie)點為常(chang)開(kai)接(jie)(jie)(jie)(jie)點，處于接(jie)(jie)(jie)(jie)通(tong)位置(zhi)的接(jie)(jie)(jie)(jie)點為常(chang)閉接(jie)(jie)(jie)(jie)點。在(zai)一個(ge)常(chang)開(kai)接(jie)(jie)(jie)(jie)點和一個(ge)常(chang)閉接(jie)(jie)(jie)(jie)點的中(zhong)間，有一個(ge)動接(jie)(jie)(jie)(jie)點被稱作(zuo)轉換(huan)接(jie)(jie)(jie)(jie)點。在(zai)同一個(ge)繼電(dian)器中(zhong)，可以具有一個(ge)或數個(ge)常(chang)開(kai)接(jie)(jie)(jie)(jie)點、常(chang)閉接(jie)(jie)(jie)(jie)點和轉換(huan)接(jie)(jie)(jie)(jie)點。
電(dian)磁(ci)繼(ji)電(dian)器(qi)(qi)中一般只有一個(ge)(ge)線圈(quan)。為了(le)在電(dian)路(lu)上清楚而簡便地把繼(ji)電(dian)器(qi)(qi)表示(shi)出(chu)來，通(tong)常用一個(ge)(ge)文字(zi)符號(hao)表示(shi)繼(ji)電(dian)器(qi)(qi)線圈(quan)和屬(shu)于它的接(jie)點，各組(zu)接(jie)點則標以角(jiao)標注明。
啟動(dong)繼電(dian)器的(de)常見故障
啟(qi)動(dong)繼電器(qi)發生故(gu)障時，會使壓縮機(ji)運轉失調(diao)、啟(qi)動(dong)電容器(qi)啟(qi)動(dong)后(hou)(hou)不(bu)能(neng)(neng)從電路上切斷或開機(ji)前常閉觸(chu)點斷開后(hou)(hou)壓縮機(ji)不(bu)能(neng)(neng)啟(qi)動(dong)。過(guo)載保護繼電器(qi)發生故(gu)障時，會使空調(diao)器(qi)不(bu)能(neng)(neng)正常運轉，造(zao)成(cheng)的(de)原因(yin)是繼電器(qi)線頭(tou)松動(dong)、脫落，接觸(chu)點磨(mo)損或熔焊、過(guo)臟、凹凸不(bu)平，線圈短路或斷路等。
對使用(yong)啟(qi)動(dong)(dong)(dong)繼電(dian)器(qi)的(de)壓縮(suo)機(ji)，當聽到(dao)壓縮(suo)機(ji)有“嗡嗡”聲而不(bu)能啟(qi)動(dong)(dong)(dong)時(shi)，應檢查啟(qi)動(dong)(dong)(dong)繼電(dian)器(qi)觸(chu)點(dian)是否良好。繼電(dian)器(qi)的(de)主要故(gu)障(zhang)是復位彈(dan)簧片彈(dan)力減弱(ruo)，啟(qi)動(dong)(dong)(dong)時(shi)觸(chu)頭(tou)閉合而難(nan)于跳(tiao)開。可(ke)調整啟(qi)動(dong)(dong)(dong)電(dian)流(liu)調節螺(luo)釘(ding)，若調節螺(luo)釘(ding)不(bu)易(yi)擰動(dong)(dong)(dong)，可(ke)用(yong)平鉗將(jiang)彈(dan)簧向外扳動(dong)(dong)(dong)，直到(dao)調至(zhi)正(zheng)常。
