交(jiao)流接觸(chu)器利用(yong)主接點(dian)來控制電路，正泰(tai)接觸(chu)器報價，

用輔(fu)助接點來(lai)導通控制回路。

主(zhu)接(jie)點(dian)(dian)一般是常(chang)開接(jie)點(dian)(dian)，而輔助(zhu)接(jie)點(dian)(dian)常(chang)有兩對常(chang)開接(jie)點(dian)(dian)和常(chang)閉接(jie)點(dian)(dian)，小型的接(jie)觸器也經常(chang)作為中間繼電(dian)器配合(he)主(zhu)電(dian)路使用。

交流(liu)接觸器(qi)的接點，由銀(yin)鎢合金制成，連云(yun)港正泰接觸器(qi)，具有(you)良好的導電性(xing)和(he)耐高溫燒蝕性(xing)。

選擇接觸器時應注意以下幾點。

1、主觸頭的額定電壓≥負載額定電壓。

2、主觸(chu)頭(tou)的額定電(dian)流(liu)≥1.3倍(bei)負載額定電(dian)流(liu)。

3、線(xian)圈額定電壓(ya)。當(dang)線(xian)路(lu)簡單、使用電器較(jiao)少時，可(ke)選(xuan)用220V 或(huo)380V；當(dang)線(xian)路(lu)復雜、使用電器較(jiao)多(duo)或(huo)不(bu)太1安全的場所，可(ke)選(xuan)用36V、110V或(huo)127V。

4、接觸器的觸頭數量、種類應滿足控制(zhi)線路(lu)要求。

5、操作頻(pin)(pin)率(lv)（每小時觸(chu)頭通(tong)斷次數(shu)）。當(dang)通(tong)斷電流(liu)(liu)較大及(ji)通(tong)斷頻(pin)(pin)率(lv)超過規定數(shu)值時，應選用額定電流(liu)(liu)大一級的接觸(chu)器型(xing)號。否則會使觸(chu)頭嚴(yan)重發(fa)熱，甚至熔焊在一起，造(zao)成(cheng)電動機等負(fu)載(zai)缺相運(yun)行。
