德國pilz繼電器皮爾茲pila熱敏電阻監(jiān)測(cè)繼電器,電動(dòng)機(jī)在實(shí)際啟動(dòng)中,如拖動(dòng)生產(chǎn)機(jī)械進(jìn)行工作過程中,若機(jī)械出現(xiàn)不正常情況或電路異常使電動(dòng)機(jī)遇到過載,則電動(dòng)機(jī)轉(zhuǎn)速下降,繞組中電流將增大,使得電動(dòng)機(jī)繞組溫度升高。若過載電流不大且過載時(shí)間較短,電動(dòng)機(jī)繞組不超過允許溫升,這種過載是允許。

德國pilz繼電器皮爾茲熱敏電阻監(jiān)測(cè)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(hù)繼電器,控制繼電器;有觸點(diǎn)繼電器,無觸點(diǎn)繼電器 ;敞開式(主體元件無防護(hù)措施)、封閉式(加保護(hù)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(shí)間繼電器等。20世紀(jì)后,繼電器有很大發(fā)展,先后出現(xiàn)磁性無觸點(diǎn)繼電器、半導(dǎo)體無觸點(diǎn)繼電器、集成電路式電子時(shí)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(hù)繼電器和智能化繼電器。 皮爾茲熱敏電阻監(jiān)測(cè)繼電器制造廠控制繼電器靈敏度并對(duì)其進(jìn)行判斷、考核的參數(shù)。對(duì)用戶來講,它只是一個(gè)工作下極限參數(shù)值。控制安全系數(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(dòng)、沖擊條件下,將使繼電器工作不可靠。整機(jī)設(shè)計(jì)時(shí),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(fù)載來計(jì)算實(shí)際電壓,特別是電源內(nèi)阻大時(shí)更是如此。當(dāng)用三極管作為開關(guān)元件控制線圈通斷時(shí),三極管必須處于開關(guān)狀態(tài),對(duì)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(huì)增加銜鐵的沖擊磨損,增加觸點(diǎn)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%。
