電磁繼電器的工作原理和特性
電磁式繼電器一般由鐵芯、線圈、銜鐵、觸點(diǎn)簧片等組成的。只要在線圈兩端加上一定的電壓，線圈中就會(huì)流過一定的電流，從而產(chǎn)生電磁效應(yīng)，銜鐵就會(huì)在電磁力吸引的作用下克服返回彈簧的拉力吸向鐵芯，從而帶動(dòng)銜鐵的動(dòng)觸點(diǎn)與靜觸點(diǎn)（常開觸點(diǎn)）吸合。當(dāng)線圈斷電后，電磁的吸力也隨之消失，銜鐵就會(huì)在彈簧的反作用力返回原來的位置，使動(dòng)觸點(diǎn)與原來的靜觸點(diǎn)（常閉觸點(diǎn)）吸合。這樣吸合、釋放，從而達(dá)到了在電路中的導(dǎo)通、切斷的目的。對(duì)于繼電器的“常開、常閉”觸點(diǎn)，可以這樣來區(qū)分：繼電器線圈未通電時(shí)處于斷開狀態(tài)的靜觸點(diǎn)，稱為“常開觸點(diǎn)”;處于接通狀態(tài)的靜觸點(diǎn)稱為“常閉觸點(diǎn)”。

　PILZ皮爾茲繼電器原理特點(diǎn)
 　　1、空氣阻尼式時(shí)間繼電器又稱為氣囊式時(shí)間繼電器，它是根據(jù)空氣壓縮產(chǎn)生的阻力來進(jìn)行延時(shí)的，其結(jié)構(gòu)簡(jiǎn)單，價(jià)格便宜，延時(shí)范圍大（0.4~180s），但延時(shí)精確度低。
 　　2、電磁式時(shí)間繼電器延時(shí)時(shí)間短（0.3~1.6s），但它結(jié)構(gòu)比較簡(jiǎn)單，通常用在斷電延時(shí)場(chǎng)合和直流電路中。
 　　3、電動(dòng)式時(shí)間繼電器的原理與鐘表類似，它是由內(nèi)部電動(dòng)機(jī)帶動(dòng)減速齒輪轉(zhuǎn)動(dòng)而獲得延時(shí)的。這種繼電器延時(shí)精度高，延時(shí)范圍寬（0.4~72h），但結(jié)構(gòu)比較復(fù)雜，價(jià)格很貴。
 　　4、晶體管式時(shí)間繼電器又稱為電子式時(shí)間繼電器，它是利用延時(shí)電路來進(jìn)行延時(shí)的。這種繼電器精度高，體積小。皮爾茲時(shí)間繼電器可分為通電延時(shí)型和斷電延時(shí)型兩種類型。

 　　空氣阻尼型時(shí)間繼電器的延時(shí)范圍大（有0.4～60s和0.4～180s兩種），它結(jié)構(gòu)簡(jiǎn)單,但準(zhǔn)確度較低。當(dāng)線圈通電時(shí)，銜鐵及托板被鐵心吸引而瞬時(shí)下移，使瞬時(shí)動(dòng)作觸點(diǎn)接通或斷開。但是活塞桿和杠桿不能同時(shí)跟著銜鐵一起下落，因?yàn)榛钊麠U的上端連著氣室中的橡皮膜，當(dāng)活塞桿在釋放彈簧的作用下開始向下運(yùn)動(dòng)時(shí)，橡皮膜隨之向下凹,上面空氣室的空氣變得稀薄而使活塞桿受到阻尼作用而緩慢下降。經(jīng)過一定時(shí)間，活塞桿下降到一定位置，便通過杠桿推動(dòng)延時(shí)觸點(diǎn)動(dòng)作，使動(dòng)斷觸點(diǎn)斷開，動(dòng)合觸點(diǎn)閉合。從線圈通電到延時(shí)觸點(diǎn)完成動(dòng)作，這段時(shí)間就是繼電器的延時(shí)時(shí)間。延時(shí)時(shí)間的長(zhǎng)短可以用螺釘調(diào)節(jié)空氣室進(jìn)氣孔的大小來改變。吸引線圈斷電后，繼電器依靠恢復(fù)彈簧的作用而復(fù)原?？諝饨?jīng)出氣孔被迅速排出。
 　　時(shí)間繼電器：當(dāng)加上或除去輸入信號(hào)時(shí)，輸出部分需延時(shí)或*到規(guī)定的時(shí)間才閉合或斷開其被控線路的繼電器。

 　　皮爾茲繼電器分類：
 　　a,電磁時(shí)間繼電器：當(dāng)線圈加上信號(hào)后，通過減緩電磁鐵的磁場(chǎng)變化而后的延時(shí)的時(shí)間繼電器。
 　　b,電子時(shí)間繼電器：由分立元件組成的電子延時(shí)線路所構(gòu)成的時(shí)間繼電器，或由固體延時(shí)線路構(gòu)成的時(shí)間繼電器。
 　　c,混合式時(shí)間繼電器：由電子或固體延時(shí)線路和電磁繼電器組合構(gòu)成的時(shí)間繼電器。
