德國pilz繼電器pila熱敏電阻監(jiān)測繼電器

使用繼電器首先要對它的簡單工作原理進行一些了解，工作原理要找一些可靠性較高的工司去參考，上海歐噴是專業(yè)做進口自動化產(chǎn)品，所提供的產(chǎn)品信息均為上介紹，可做為參考性較高的資料使用。
德國pilz皮爾茲熱敏電阻監(jiān)測繼電器工作原理知識: 電動機在實際啟動中，如拖動生產(chǎn)機械進行工作過程中，若機械出現(xiàn)不正常情況或電路異常使電動機遇到過載，則電動機轉(zhuǎn)速下降，繞組中電流將增大，使得電動機繞組溫度升高。若過載電流不大且過載時間較短，電動機繞組不超過允許溫升，這種過載是允許。但若過載時間長，過載電流大，電動機繞組溫升就會超過允許值，使電動機繞組老化，縮短電動機運用壽命，嚴重時甚到會使電動機繞組燒毀。所對，這種過載是電動機不能承受。熱繼電器就是采用電流熱反應(yīng)原理知識，在出現(xiàn)電動機不能承受過載時切斷電動機電路，為電動機供應(yīng)過載保護保護電器。

  德國pilz繼電器皮爾茲熱敏電阻監(jiān)測繼電器有多種分類。如電氣量繼電器（其輸入量可為電流、電壓、頻率、功率等），非電量繼電器（其輸入量可為溫度、壓力、速度等）；保護繼電器，控制繼電器；有觸點繼電器，無觸點繼電器 ；敞開式（主體元件無防護措施）、封閉式（加保護外殼）、密封式（外殼內(nèi)外無氣體交換）繼電器等等。常用的按工作原理分類的繼電器有電磁繼電器 、極化繼電器、舌簧繼電器、熱繼電器和時間繼電器等。20世紀后，繼電器有很大發(fā)展，先后出現(xiàn)磁性無觸點繼電器、半導(dǎo)體無觸點繼電器、集成電路式電子時間繼電器、固態(tài)繼電器、印刷電路板安裝式（雙列直插式）繼電器，以及帶微處理器的保護繼電器和智能化繼電器。 皮爾茲熱敏電阻監(jiān)測繼電器制造廠控制繼電器靈敏度并對其進行判斷、考核的參數(shù)。對用戶來講，它只是一個工作下極限參數(shù)值?？刂瓢踩禂?shù)是工作電壓（電流）/吸合電壓（電流），如果在吸合值下使用繼電器，是不可靠的、不安全的，環(huán)境溫度升高或處于振動、沖擊條件下，將使繼電器工作不可靠。整機設(shè)計時，不能以空載電壓作為繼電器工作電壓依據(jù)，而應(yīng)將線圈接入作為負載來計算實際電壓，特別是電源內(nèi)阻大時更是如此。當(dāng)用三極管作為開關(guān)元件控制線圈通斷時，三極管必須處于開關(guān)狀態(tài)，對6VDC以下工作電壓的繼電器來講，還應(yīng)扣除三極管飽和壓降。當(dāng)然，并非工作值加得愈高愈好，超過額定工作值太高會增加銜鐵的沖擊磨損，增加觸點回跳次數(shù)，縮短電氣壽命，一般，工作值為吸合值的1.5倍，工作值的誤差一般為±10%。

  一般由輸入感測機構(gòu)和輸出執(zhí)行機構(gòu)兩部分組成。前者用于反映輸入量的變化，后者完成觸點分合動作（對有觸點繼電器）或半導(dǎo)體元件的通斷（對無觸點繼電器）。繼電器具有跳躍的輸入-輸出特性 。當(dāng)繼電器接受一個輸入信號X時，只有它達到動作值Xd，繼電器才動作，輸出從零躍至Ymax。輸入信號繼續(xù)增大，輸出信號仍為Ymax不變。繼電器動作之后，如果減少輸入信號，則繼電器只在輸入減少到Xf時才動作，返回起始位置，輸出信號躍回零。這一特性稱為繼電特性。這里，使繼電器開始動作的輸入量值（動作值）、使繼電器恢復(fù)原狀態(tài)的輸入zui大量值（返回值）、觸點的額定電壓與電流（觸點額定量值）、繼電器由一種狀態(tài)變至另一種狀態(tài)的時間（動作時間）是繼電器的主要技術(shù)參數(shù)。它們既表征繼電器工作過程的性能，又是選用繼電器的依據(jù)。777434P2HZ X1P 110VAC 3n/o 1n/c 2so
