特點

永磁(ci)交流接觸器的革(ge)新技(ji)術特點是(shi)用(yong)永磁(ci)式驅動(dong)機(ji)構取代了(le)(le)(le)傳統(tong)(tong)的電(dian)(dian)(dian)磁(ci)鐵驅動(dong)機(ji)構,即利用(yong)磁(ci)鐵與微電(dian)(dian)(dian)子模塊組(zu)成的控(kong)(kong)制裝(zhuang)置,置換了(le)(le)(le)傳統(tong)(tong)產(chan)品中的電(dian)(dian)(dian)磁(ci)裝(zhuang)置,運行中無工作電(dian)(dian)(dian)流,僅由微弱(ruo)信(xin)號電(dian)(dian)(dian)流(0.8-1.5mA)。微電(dian)(dian)(dian)子模塊中包(bao)含六個基本(ben)的部(bu)分：1.電(dian)(dian)(dian)源整流; 2.控(kong)(kong)制電(dian)(dian)(dian)源電(dian)(dian)(dian)壓(ya)實時檢測; 3.釋放儲能(neng)(有(you)(you)的也有(you)(you)吸合儲能(neng),但不是(shi)必須有(you)(you)); 4.儲能(neng)電(dian)(dian)(dian)容電(dian)(dian)(dian)壓(ya)檢測; 5.抗(kang)干擾門檻電(dian)(dian)(dian)壓(ya)檢測;6.釋放邏輯電(dian)(dian)(dian)路。這6部(bu)分是(shi)永磁(ci)操作機(ji)構電(dian)(dian)(dian)子控(kong)(kong)制部(bu)分的必要組(zu)成,如果缺少(shao)任何(he)一個部(bu)分,操作機(ji)構在特定(ding)的情況下就沒法正(zheng)常工作。這6個部(bu)分,也就決(jue)定(ding)了(le)(le)(le)操作機(ji)構可以具備抗(kang)晃電(dian)(dian)(dian)功能(neng)。

①.節能：

傳(chuan)統(tong)接觸器(qi)的(de)(de)合(he)(he)閘(zha)保持(chi)是靠(kao)合(he)(he)閘(zha)線(xian)圈通(tong)(tong)(tong)電(dian)(dian)產生電(dian)(dian)磁(ci)力來(lai)(lai)克(ke)服(fu)分閘(zha)彈(dan)簧來(lai)(lai)實現的(de)(de)，一旦(dan)電(dian)(dian)流(liu)變(bian)小(xiao)使(shi)產生的(de)(de)電(dian)(dian)磁(ci)力不(bu)(bu)足以克(ke)服(fu)彈(dan)簧的(de)(de)反作用力，接觸器(qi)就不(bu)(bu)能保持(chi)合(he)(he)閘(zha)狀(zhuang)態(tai)，所以，傳(chuan)統(tong)交流(liu)接觸器(qi)的(de)(de)合(he)(he)閘(zha)保持(chi)是必須靠(kao)線(xian)圈持(chi)續(xu)不(bu)(bu)斷的(de)(de)通(tong)(tong)(tong)電(dian)(dian)來(lai)(lai)維持(chi)的(de)(de)，這個(ge)電(dian)(dian)流(liu)從(cong)數十到(dao)數千毫安(an)。而永磁(ci)交流(liu)接觸器(qi)合(he)(he)閘(zha)保持(chi)依靠(kao)的(de)(de)是永磁(ci)力，而不(bu)(bu)需(xu)要線(xian)圈通(tong)(tong)(tong)過(guo)電(dian)(dian)生電(dian)(dian)磁(ci)力來(lai)(lai)進(jin)行合(he)(he)閘(zha)保持(chi)，只(zhi)有電(dian)(dian)子模(mo)塊的(de)(de)0.8mA—1.5mA的(de)(de)工作電(dian)(dian)流(liu)，因而，能限度地節(jie)約電(dian)(dian)能，節(jie)電(dian)(dian)率高達99.8%以上(shang)。

一:一般三相接觸器一共(gong)有8個點(dian)，三路(lu)輸入，三路(lu)輸出，還(huan)有是控(kong)制(zhi)點(dian)兩個。輸出和輸入是對應的(de)，很容易能(neng)看出來(lai)。如果(guo)要加自鎖的(de)話，則(ze)還(huan)需(xu)要從輸出點(dian)的(de)一個端(duan)子將(jiang)線接到控(kong)制(zhi)點(dian)上面。

二(er): 首先應該知道交(jiao)流接(jie)(jie)觸器的(de)原(yuan)理。他是(shi)(shi)用外界電(dian)源(yuan)(yuan)來加在(zai)(zai)線(xian)圈(quan)上，產生電(dian)磁場。加電(dian)吸合，斷(duan)電(dian)后(hou)接(jie)(jie)觸點(dian)就斷(duan)開。知道原(yuan)理后(hou)，你應該弄清楚(chu)外加電(dian)源(yuan)(yuan)的(de)接(jie)(jie)點(dian)，也就是(shi)(shi)線(xian)圈(quan)的(de)兩個(ge)接(jie)(jie)點(dian)，一(yi)般在(zai)(zai)接(jie)(jie)觸器的(de)下部(bu)，并(bing)且(qie)各(ge)在(zai)(zai)一(yi)邊。其他的(de)幾(ji)路輸(shu)(shu)入和輸(shu)(shu)出一(yi)般在(zai)(zai)上部(bu)，一(yi)看就知道。還(huan)(huan)要注(zhu)意外加電(dian)源(yuan)(yuan)的(de)電(dian)壓是(shi)(shi)多少(220V或(huo) 380V)，一(yi)般都標得有(you)。并(bing)且(qie)注(zhu)意接(jie)(jie)觸點(dian)是(shi)(shi)常閉還(huan)(huan)是(shi)(shi)常開。如果有(you)自鎖控制，根據(ju)原(yuan)理理一(yi)下線(xian)路就可以了。

選擇接(jie)觸器的額(e)定(ding)參數

根據被控對象和工作參(can)數如(ru)電壓、電流、功率(lv)、頻率(lv)及(ji)工作制等確定(ding)接觸(chu)器(qi)的額定(ding)參(can)數。

1)接觸器的(de)線圈電(dian)(dian)壓，一般應低一些為好，這樣(yang)對(dui)接觸器的(de)絕緣要(yao)求可以降(jiang)低，使(shi)用時也較安全。但為了方便和減(jian)少設(she)備，常按實際(ji)電(dian)(dian)網電(dian)(dian)壓選取。

2)電動機的操作頻率不高，如(ru)壓縮(suo)機、水泵、風機、空調、沖床等(deng)，接觸器(qi)(qi)額定電流(liu)大于負荷(he)額定電流(liu)即可。接觸器(qi)(qi)類型(xing)可選(xuan)用CJl0、CJ20等(deng)。

3)對重任務型(xing)電(dian)機(ji)(ji)，如(ru)機(ji)(ji)床主電(dian)機(ji)(ji)、升降設(she)備、絞盤、破碎機(ji)(ji)等(deng)，其平均(jun)操作頻率(lv)超過100次/min，運行于(yu)起動(dong)、點(dian)動(dong)、正反向(xiang)制動(dong)、反接(jie)(jie)制動(dong)等(deng)狀態，可選(xuan)用CJl0Z、CJl2型(xing)的接(jie)(jie)觸器(qi)。為了保(bao)證電(dian)壽命(ming)，可使接(jie)(jie)觸器(qi)降容使用。選(xuan)用時，接(jie)(jie)觸器(qi)額(e)定(ding)電(dian)流大(da)于(yu)電(dian)機(ji)(ji)額(e)定(ding)電(dian)流。

4)對特重任務(wu)電(dian)機，如印(yin)刷(shua)機、鏜床等(deng)，操作頻率很高(gao)，可達600～12000次/h，經常運行(xing)于起動、反(fan)接制動、反(fan)向(xiang)等(deng)狀(zhuang)態(tai)，接觸(chu)器大(da)致(zhi)可按電(dian)壽命及起動電(dian)流選用，接觸(chu)器型號選CJl0Z、CJl2等(deng)。

5)交流回路中(zhong)的電(dian)(dian)容(rong)(rong)(rong)器(qi)投入電(dian)(dian)網或從電(dian)(dian)網中(zhong)切除時，接(jie)(jie)觸(chu)器(qi)選擇應考慮電(dian)(dian)容(rong)(rong)(rong)器(qi)的合(he)閘沖(chong)擊電(dian)(dian)流。一般地(di)，接(jie)(jie)觸(chu)器(qi)的額定電(dian)(dian)流可(ke)按電(dian)(dian)容(rong)(rong)(rong)器(qi)的額定電(dian)(dian)流的1.5倍(bei)選取，型(xing)號(hao)選CJ10、CJ20等。
