在控制電路中用的繼電器大多數(shù)是電磁式繼電器。電磁式繼電器具有結(jié)構(gòu)簡單，價格低廉，使用維護方便，觸點容量小（一般在SA以下），觸點數(shù)量多且無主輔之分，無滅弧裝置，體積小，動作迅速、準(zhǔn)確，控制靈敏、可靠等特點，***地應(yīng)用于低壓控制系統(tǒng)中。常用的電磁式繼電器有電流繼電器、電壓繼電器、中間繼電器以及各種小型通用繼電器等。 </p> <p> 電磁式繼電器的結(jié)構(gòu)和工作原理與接觸器的相似，主要由電磁機構(gòu)和觸點組成。電磁式繼電器有直流和交流兩種。在線圈兩端加上電壓或通人電流，產(chǎn)生電磁力，當(dāng)電磁力大于彈簧反力時，吸動銜鐵使常開常閉接點動作；當(dāng)線圈的電壓或電流下降或消失時銜鐵釋放，接點復(fù)位。 </p> <p> <br /> </p> <p> <br />

在常規(guī)Y-△的電動機控制線路中，時間繼電器的延時控制使電機在Y形啟動切換至△形運行起到有效的控制。 </p> <p> 按下Y-△控制回路啟動按鈕SB2，時間繼電器KT得電，在得電的同時KT的瞬動觸點對SB2形成自鎖，KM3接觸器線圈得電，KM3主觸頭閉合，其常開輔助觸頭閉合，主回路KM1接觸器得電，主回路接通；KM3常閉輔助觸頭斷開，確保接觸器KM3工作時，KM2不能投入工作，此時電動機處于Y形啟動狀態(tài)。 </p> <p> 當(dāng)時間繼電器KT延時到達后（KT的時間設(shè)置可根據(jù)所控制Y-△啟動電動機的功率來設(shè)定）。時間繼電器的延時常開和延時常閉觸頭轉(zhuǎn)換，致使交流接觸器KM3線圈失電，主觸頭斷開，交流接觸器KM2得電，其輔助觸頭對KM1、KT觸點進行自鎖，保證交流接觸器KM2吸合工作，使電機在△形運行。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 時間<strong>繼電器</strong>的接線方法（一） </p> <p> 時間繼電器的電氣控制系統(tǒng)中是一個非常重要的元器件。一般分為通電延時和斷電延時兩種類型。從動作的原理上有電子式、機械式等。電子式的是采用電容充放電再配合電子元件的原理來實現(xiàn)延時動作。機械式的樣式較多，有利用氣囊、彈簧的氣囊式. </p> <p> 時間繼電器的接線方法 </p> <p> ***、控制接線：你把它看成直流繼電器來考慮。3、7用來接12V控制電壓；2、7用來接24V控制電壓。其中的7當(dāng)成直流電的負(fù)極，使用時接到零線。2接220V的火線。 </p> <p> 第二、工作控制：雖然控制電壓接上了，但是是否起控制作用，由面板上的計時器決定。 </p> <p> <br /> </p> <p> <br /> 中間繼電器的作用是什么？</p><div

該延時電路的**IC是由14位二進制串行計數(shù)器/分頻器構(gòu)成，IC內(nèi)部由振蕩器和14級分頻器組成，振蕩器部分可由電阻Rt和電容Cr構(gòu)成振蕩器，產(chǎn)生固定的振蕩頻率,主振產(chǎn)生的矩形波可進入14級分頻器，并通過10個輸出端得到不同的分頻系數(shù)（分頻**小可得到16分頻Q4，比較大可得到16384分頻Q14），便可得到所需的定時控制。待分頻延時到達后，輸出端的高電平使驅(qū)動電路三極管導(dǎo)通工作，從而使執(zhí)行繼電器工作，相應(yīng)的延時觸點對所需**線路進行定時控制，IC振蕩也隨輸出的高電平經(jīng)V6使之停振。發(fā)光管V1也隨繼電器同時工作，起到延時到達指示。 </p> <p> 集成的公共清零端Cr（12腳）在電路上電的同時由C4、R3組成的微分電路上產(chǎn)生瞬間尖脈沖，使計數(shù)器的輸出端復(fù)位清零，并同時使振蕩停振。待上電瞬間結(jié)束后，振蕩器開始振蕩工作，電路即進入分頻延時工作狀態(tài)。 </p> <p> <br /> </p> <p> <br /> 時間繼電器的抗電磁干擾措施。浙江品牌繼電器</p><p
