邦納banner繼電器電路組成的兩個部分

中間(jian)繼(ji)(ji)電器(qi)的觸點具有一(yi)(yi)定的帶負荷能力，當負載容量比(bi)(bi)較小時，可以(yi)(yi)用來(lai)替代(dai)小型(xing)接(jie)觸器(qi)使(shi)用，比(bi)(bi)如電動卷閘(zha)門和一(yi)(yi)些小家電的控制(zhi)(zhi)。這(zhe)樣的優點是不僅可以(yi)(yi)起(qi)到控制(zhi)(zhi)的目的，而(er)且可以(yi)(yi)節省空(kong)間(jian)，使(shi)電器(qi)的控制(zhi)(zhi)部(bu)分做得比(bi)(bi)較精致。這(zhe)是中間(jian)繼(ji)(ji)電器(qi)zui常見的用法，例如，在(zai)(zai)電路(lu)控制(zhi)(zhi)系統中一(yi)(yi)個接(jie)觸器(qi)的接(jie)點需要控制(zhi)(zhi)多個接(jie)觸器(qi)或(huo)其他元件時而(er)是在(zai)(zai)線路(lu)中增加(jia)一(yi)(yi)個中間(jian)繼(ji)(ji)電器(qi)。

邦納banner繼電器電路組成的兩個部分一(yi)般的電(dian)路(lu)常分成(cheng)主(zhu)電(dian)路(lu)和控(kong)(kong)(kong)制(zhi)(zhi)電(dian)路(lu)兩部分，繼電(dian)器(qi)(qi)(qi)主(zhu)要(yao)用于控(kong)(kong)(kong)制(zhi)(zhi)電(dian)路(lu)，接(jie)觸器(qi)(qi)(qi)主(zhu)要(yao)用于主(zhu)電(dian)路(lu)；通過繼電(dian)器(qi)(qi)(qi)可實現(xian)用一(yi)路(lu)控(kong)(kong)(kong)制(zhi)(zhi)信號控(kong)(kong)(kong)制(zhi)(zhi)另一(yi)路(lu)或幾路(lu)信號的功(gong)能(neng)，完成(cheng)啟動(dong)、停止、聯動(dong)等控(kong)(kong)(kong)制(zhi)(zhi)，主(zhu)要(yao)控(kong)(kong)(kong)制(zhi)(zhi)對象是接(jie)觸器(qi)(qi)(qi)；接(jie)觸器(qi)(qi)(qi)的觸頭比較(jiao)大，承載(zai)能(neng)力強(qiang)，通過它來實現(xian)弱電(dian)到強(qiang)電(dian)的控(kong)(kong)(kong)制(zhi)(zhi)，控(kong)(kong)(kong)制(zhi)(zhi)對象是電(dian)器(qi)(qi)(qi)。

中間繼電(dian)(dian)器(qi)(qi)的(de)(de)(de)(de)接點容(rong)量雖然不是很(hen)(hen)大，但也具有一定(ding)的(de)(de)(de)(de)帶負載能力，同時(shi)其(qi)驅動(dong)所需要的(de)(de)(de)(de)電(dian)(dian)流(liu)又很(hen)(hen)小，因此可以用中間繼電(dian)(dian)器(qi)(qi)來擴大接點容(rong)量。比如一般不能直接用感應開關、三(san)極管的(de)(de)(de)(de)輸(shu)出去控(kong)制(zhi)負載比較大的(de)(de)(de)(de)電(dian)(dian)器(qi)(qi)元件。當輸(shu)入量（如電(dian)(dian)壓、電(dian)(dian)流(liu)、溫(wen)度等）達到(dao)規定(ding)值時(shi)，使被控(kong)制(zhi)的(de)(de)(de)(de)輸(shu)出電(dian)(dian)路導通或斷開的(de)(de)(de)(de)電(dian)(dian)器(qi)(qi)。

可分為電(dian)(dian)氣(qi)量（如電(dian)(dian)流、電(dian)(dian)壓、頻率、功率等）繼電(dian)(dian)器及非電(dian)(dian)氣(qi)量（如溫度、壓力(li)(li)、速(su)度等）繼電(dian)(dian)器兩(liang)大類。具有動(dong)作快、工作穩定(ding)、使(shi)用壽(shou)命長、體(ti)積小等優點。廣泛(fan)應用于電(dian)(dian)力(li)(li)保(bao)護、自動(dong)化、運動(dong)、遙控(kong)、測量和通信等裝置中(zhong)(zhong)(zhong)。而是在(zai)控(kong)制線路中(zhong)(zhong)(zhong)使(shi)用中(zhong)(zhong)(zhong)間繼電(dian)(dian)器，通過中(zhong)(zhong)(zhong)間繼電(dian)(dian)器來控(kong)制其他負(fu)載，達(da)到擴(kuo)大控(kong)制容(rong)量的(de)目的(de)。

在工(gong)業(ye)控(kong)(kong)制(zhi)線路中(zhong)，常(chang)常(chang)會出現(xian)這(zhe)樣(yang)的情(qing)況，控(kong)(kong)制(zhi)要求(qiu)需(xu)要使用接(jie)觸器(qi)的常(chang)閉接(jie)點(dian)才能達到(dao)控(kong)(kong)制(zhi)目的，但是接(jie)觸器(qi)本身所帶的常(chang)閉接(jie)點(dian)已經用完，無法完成控(kong)(kong)制(zhi)任(ren)務。這(zhe)時可(ke)以將一個(ge)中(zhong)間繼(ji)電器(qi)與(yu)原來的接(jie)觸器(qi)線圈并聯

邦納banner繼電器電路組成的兩個部分用(yong)中(zhong)間(jian)繼(ji)電(dian)(dian)器的(de)(de)常閉接點(dian)去控(kong)制(zhi)(zhi)相應的(de)(de)元(yuan)件，轉換一下(xia)接點(dian)類型，達到所需要(yao)的(de)(de)控(kong)制(zhi)(zhi)目(mu)的(de)(de)。在一些控(kong)制(zhi)(zhi)線(xian)路(lu)中(zhong)，一些電(dian)(dian)器元(yuan)件的(de)(de)通斷常常使(shi)用(yong)中(zhong)間(jian)繼(ji)電(dian)(dian)器，用(yong)其接點(dian)的(de)(de)開閉來控(kong)制(zhi)(zhi)，例如如彩電(dian)(dian)或顯示(shi)器中(zhong)常見的(de)(de)自動(dong)消(xiao)(xiao)磁電(dian)(dian)路(lu)，三(san)極管控(kong)制(zhi)(zhi)中(zhong)間(jian)繼(ji)電(dian)(dian)器的(de)(de)通斷，從而達到控(kong)制(zhi)(zhi)消(xiao)(xiao)磁線(xian)圈通斷的(de)(de)作用(yong)。
