描述

531X304IBDARG1 F31X304IBDAMG1-00609

熱繼電器是由流入熱元件的電流產(chǎn)生熱量,使有不同膨脹系數(shù)的雙金屬片發(fā)生形變,當(dāng)形變達(dá)到一定距離時(shí),就推動(dòng)連桿動(dòng)作,使控制電路斷開,從而使接觸器失電,主電路斷開,實(shí)現(xiàn)電動(dòng)機(jī)的過載保護(hù)。繼電器作為電動(dòng)機(jī)的過載保護(hù)元件,以其體積小,結(jié)構(gòu)簡(jiǎn)單、成本低等優(yōu)點(diǎn)在生產(chǎn)中得到了廣泛應(yīng)用。
熱繼電器是用于電動(dòng)機(jī)或其它電氣設(shè)備、電氣線路的過載保護(hù)的保護(hù)電器。
電動(dòng)機(jī)在實(shí)際運(yùn)行中,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)不正常的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、繞組中的電流將增大,使電動(dòng)機(jī)的繞組溫度升高。若過載電流不大且過載的時(shí)間較短,電動(dòng)機(jī)繞組不超過允許溫升,這種過載是允許的。但若過載時(shí)間長(zhǎng),過載電流大,電動(dòng)機(jī)繞組的溫升就會(huì)超過允許值,使電動(dòng)機(jī)繞組老化,縮短電動(dòng)機(jī)的使用壽命,嚴(yán)重時(shí)甚至?xí)闺妱?dòng)機(jī)繞組燒毀。所以,這種過載是電動(dòng)機(jī)不能承受的。熱繼電器就是利用電流的熱效應(yīng)原理,在出現(xiàn)電動(dòng)機(jī)不能承受的過載時(shí)切斷電動(dòng)機(jī)電路,為電動(dòng)機(jī)提供過載保護(hù)的保護(hù)電器。
熱繼電器的作用是:主要用來(lái)對(duì)異步電動(dòng)機(jī)進(jìn)行過載保護(hù),他的工作原理是過載電流通過熱元件后,使雙金屬片加熱彎曲去推動(dòng)動(dòng)作機(jī)構(gòu)來(lái)帶動(dòng)觸點(diǎn)動(dòng)作,從而將電動(dòng)機(jī)控制電路斷開實(shí)現(xiàn)電動(dòng)機(jī)斷電熱繼電器停車,起到過載保護(hù)的作用。鑒于雙金屬片受熱彎曲過程中,熱量的傳遞需要較長(zhǎng)的時(shí)間。

選擇深圳長(zhǎng)欣,選擇放心,售后無(wú)憂大量現(xiàn)貨,當(dāng)天順豐發(fā)貨!
主營(yíng):本特利,英維思,伍德沃德,??怂共_、西屋、瑞恩、施耐德莫迪康、ABB、AB、西門子、摩托羅拉、GE發(fā)那科、安川、博世力士樂,ACSO,力士樂等各大品牌的DCS系統(tǒng)配件,機(jī)器人系統(tǒng)配件,大型伺服系統(tǒng)備件。

先介紹幾點(diǎn)經(jīng)驗(yàn)。
1、先通讀一遍“系統(tǒng)手冊(cè)”(不管能不能看懂,先了解個(gè)大概,以便學(xué)習(xí)編程時(shí)查找);
2、由位控邏輯入手,逐漸增加定時(shí)、計(jì)數(shù)等條件,把或、與、非關(guān)系理順;
3、進(jìn)而練習(xí)整數(shù)運(yùn)算、實(shí)數(shù)運(yùn)算、類型轉(zhuǎn)換;
4、量程轉(zhuǎn)換、PID調(diào)節(jié)回路的建立及P、I、D參數(shù)的理解(最好是有個(gè)物理回路驗(yàn)證,比如變頻器+電機(jī)+測(cè)速傳感器);
5、循環(huán)、順序、跳轉(zhuǎn)等程序控制(盡量避免跳轉(zhuǎn),非跳不可時(shí)也是跳的越近越好);
6、中斷、通訊、位置控制....

本人以ABB工業(yè)機(jī)器人配件DSQC系列和Motorola MVME系列,GE 卡件 模塊 驅(qū)動(dòng)器系列為主攻。各位電工朋友可根據(jù)自己的條件選擇適合自己的PLC品牌,由于PLC的基本框架大同小異,學(xué)會(huì)一種至于其它的學(xué)習(xí)起來(lái)也就簡(jiǎn)單了。
