皮爾茲時(shí)間繼電器*
德國PILZ皮爾茲時(shí)間繼電器是一種利用電磁原理或機(jī)械原理實(shí)現(xiàn)延時(shí)控制的控制電器。它的種類很多,有空氣阻尼型、電動(dòng)型和電子型等。
在交流電路中常采用空氣阻尼型德國PILZ皮爾茲時(shí)間繼電器 ,它是利用空氣通過小孔節(jié)流的原理來獲得延時(shí)動(dòng)作的。它由電磁系統(tǒng)、延時(shí)機(jī)構(gòu)和觸點(diǎn)三部分組成。
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)簡單,但準(zhǔn)確度較低。
當(dāng)線圈通電(電壓規(guī)格有AC380V、AC220V或DC220V、DC24V等)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。

pilz皮爾茲繼電器與普通繼電器的區(qū)別德國pilz皮爾茲安全繼電器的原理
1、皮爾茲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)”。
2、pilz熱敏干簧繼電器的工作原理和特性; 熱敏干簧繼電器是一種利用熱敏磁性材料檢測和控制溫度的新型熱敏開關(guān)。它由感溫磁環(huán)、恒磁環(huán)、干簧管、導(dǎo)熱安裝片、塑料襯底及其他一些附件組成。熱敏干簧繼電器不用線圈勵(lì)磁,而由恒磁環(huán)產(chǎn)生的磁力驅(qū)動(dòng)開關(guān)動(dòng)作。恒磁環(huán)能否向干簧管提供磁力是由感溫磁環(huán)的溫控特性決定的。3、pilz固態(tài)繼電器(ssr)的工作原理和特性; 固態(tài)繼電器是一種兩個(gè)接線端為輸入端,另兩個(gè)接線端為輸出端的四端器件,中間采用隔離器件實(shí)現(xiàn)輸入輸出的電隔離

皮爾茲時(shí)間繼電器是一種使用在較低的電壓或較小電流的電路上,用來接通或切斷較高電壓、較大電流的電路的電氣元件,也許可以這樣說:用來控制較高電壓或較大功率的電路的電動(dòng):給繼電器工作線圈一個(gè)控制電流,繼電器就吸合,對(duì)應(yīng)的觸點(diǎn)就接通或斷開。 在供電電路中,繼電器也被稱為接觸器
從驅(qū)動(dòng)時(shí)間繼電器工作的電源要求(驅(qū)動(dòng)線包工作電壓)來分,一般繼電器分交流繼電器與直流繼電器,分別用于交流電路和直流電路,另外,依據(jù)其工作電壓的高低,有6、9、12、24、36、110、220、380等不同的工作電壓,使用于不同的控制電路上。 時(shí)間繼電器另一個(gè)區(qū)分點(diǎn)是它的觸點(diǎn)(執(zhí)行接通或斷開被控制電路的開關(guān)),分別有常開、常閉、轉(zhuǎn)換的區(qū)別,另外還有觸點(diǎn)多少的區(qū)別,可以控制多大的工作電壓及電流(即觸點(diǎn)允許控制的功率)的區(qū)別,供不同用途選用;另外特殊觸點(diǎn)還有帶自鎖(動(dòng)作后即使控制電壓消失,觸點(diǎn)自己保持失去控制時(shí)的狀態(tài)),帶延時(shí)吸合或延時(shí)釋放功能等種類,供特殊情況下使用。
從繼電器外形來區(qū)分,有密封、小型、微型等區(qū)別。 有時(shí)候,比如說,一個(gè)控制電路從按鈕控制開始,到zui后控制負(fù)荷的時(shí)間繼電器中間,還使用了其他繼電器,因?yàn)檫@些繼電器只起控制其他繼電器工作的作用,其觸點(diǎn)負(fù)荷不需要很大,用在這些部位的繼電器,常稱為中間繼電器。 比如,使用三個(gè)按鈕與繼電器(交流接觸器)及熱保護(hù)等可以組成控制三相電動(dòng)機(jī)的正、翻轉(zhuǎn)及停止電路。洗衣機(jī)內(nèi),繼電器在微電腦控制下,接合、斷開控制電機(jī)使波輪正、反轉(zhuǎn)等,都是繼電器的任務(wù),因?yàn)槲㈦娔X的輸出不能直接驅(qū)動(dòng)洗衣機(jī)馬達(dá)工作,所以請(qǐng)了“繼電器”。 使用各種傳感器檢測的電路檢測溫度、壓力、時(shí)間等不同物理量,檢測的輸出接上繼電器,就分別組成所謂電壓繼電器、壓力繼電器等等。這類繼電器,實(shí)際上是包含繼電器在內(nèi)的電子器件,并非獨(dú)立的繼電器。
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))釋放。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)”。
繼電器是一種電子控制器件,它具有控制系統(tǒng)(又稱輸入回路)和被控制系統(tǒng)(又稱輸出回路),通常應(yīng)用于自動(dòng)控制電路中,它實(shí)際上是用較小的電流去控制較大電流的一種“自動(dòng)開關(guān)”。繼電器的作用是 在電路中起著自動(dòng)調(diào)節(jié)、安全保護(hù)、以弱控強(qiáng),轉(zhuǎn)換電路等作用。
固態(tài)繼電器(solid state relay,SSR)是利用發(fā)光二極管等發(fā)光元件與一顆光晶體管等光接收元件作成之光耦合器,觸發(fā)硅控整流體或雙向硅控整流器,因此可以接受低壓(DC或AC)信號(hào)輸入,而驅(qū)動(dòng)高壓之輸出,具隔離輸出入及控制高功率輸出之效果。固態(tài)繼電器按負(fù)載電源類型可分為交流型和直流型。按開關(guān)型式可分為常開型和常閉型。按隔離型式可分為混合型、變壓器隔離型和光電隔離型,以光電隔離型為zui多。 固態(tài)繼電器開關(guān)速度快、工作頻率高、使用壽命長、 噪聲低和工作可靠??扇〈R?guī)電磁式繼電器,被廣泛用于數(shù)位程控裝置。
德國皮爾茲PILZ繼電器的種類和原理@ 磁簧繼電器是以線圈產(chǎn)生磁場將磁簧管作動(dòng)之繼電器,為一種線圈傳感裝置。因此磁簧繼電器之特征、小型尺寸、輕量、反應(yīng)速度快、短跳動(dòng)時(shí)間等特性。當(dāng)整塊鐵磁金屬或者其它導(dǎo)磁物質(zhì)與之靠近的時(shí)候,發(fā)生動(dòng)作,開通或者閉合電路。由*磁鐵和干簧管組成。*磁鐵、干簧管固定在一個(gè)不導(dǎo)磁也不帶有磁性的支架上。以*磁鐵的南北極的連線為軸線,這個(gè)軸線應(yīng)該與干簧管的軸線重合或者基本重合。由遠(yuǎn)及近的調(diào)整*磁鐵與干簧管之間的距離,當(dāng)干簧管剛好發(fā)生動(dòng)作(對(duì)于常開的干簧管,變?yōu)殚]合;對(duì)于常閉的干簧管,變?yōu)閿嚅_)時(shí),將磁鐵的位置固定下來。這時(shí),當(dāng)有整塊導(dǎo)磁材料,例如鐵板同時(shí)靠近磁鐵和干簧管時(shí),干簧管會(huì)再次發(fā)生動(dòng)作,恢復(fù)到?jīng)]有磁場作用時(shí)的狀態(tài);當(dāng)該鐵板離開時(shí),干簧管即發(fā)生相反方向的動(dòng)作。 磁簧繼電器結(jié)構(gòu)堅(jiān)固,觸點(diǎn)為密封狀態(tài),耐用性高,可以作為機(jī)械設(shè)備的位置限制開關(guān),也可以用以探測鐵制門、窗等是否在位置
