在工作中,只要其中任一通道斷開(kāi),繼電器都會(huì)停止輸出,直到兩個(gè)通道都正常且復(fù)位后才能正常工作。要求在緊急停止解除時(shí),機(jī)器不能出現(xiàn)突然再啟動(dòng);萬(wàn)一機(jī)器電路發(fā)生故障時(shí),可以停止機(jī)器動(dòng)力電源;電路發(fā)生故障時(shí),機(jī)器不能再啟動(dòng);單靠雙重化是不行的。雙重化是必要的,但是除此之外,比如如下幾個(gè)條件,雙重化電路的互相檢查,確認(rèn)所有電路已經(jīng)斷開(kāi)一次,必要時(shí)由作業(yè)者操作便可以啟動(dòng)等條件。還有從另一個(gè)角度來(lái)說(shuō),輸入的開(kāi)關(guān)接線短路或電線外皮破損而引起的接地的可能性時(shí),必須預(yù)防因此而引起的機(jī)器突然啟動(dòng)。實(shí)際上,為了方便電路的構(gòu)成,將繼電器和其他組件組合配套,把基本的緊急停止電路、電路組成電路模塊的產(chǎn)品稱為繼電器模塊。第四要素:加工工藝,/A為冷拔加工,/B為機(jī)械加工,/BE為高機(jī)械加工。導(dǎo)軌的主要參數(shù)見(jiàn)右圖T形導(dǎo)軌主要尺寸及下表T形導(dǎo)軌主要尺寸及公差。表中所列為常見(jiàn)導(dǎo)軌而T82/B更是行業(yè)尺寸,與舊的電梯T形導(dǎo)軌J65072.1—1996中所規(guī)定的尺寸有所不同??招膶?dǎo)軌空心導(dǎo)軌即由鋼板經(jīng)冷態(tài)折彎(或滾壓)成空心的T形電梯對(duì)重用導(dǎo)軌,由于其中空的特性,它能導(dǎo)軌重量及成本。對(duì)重導(dǎo)向的作用,但是不能承受安全鉗的夾持力,所以它僅用于不裝對(duì)重安全鉗的,電梯速度不高的對(duì)重導(dǎo)軌??招膶?dǎo)軌的命ZIh類、組、型、特性、主參數(shù)和變形代號(hào)組成?!酢冃未?hào):A表示底面折邊,底面直邊省略;△——主參數(shù)代號(hào):用導(dǎo)軌單位重量表示。
使兩個(gè)繞組之間以及繞組與鐵心之間都有電氣隔離。電壓互感器在運(yùn)行時(shí),一次繞組N1并聯(lián)接在線路上,二次繞組N2并聯(lián)接儀表或繼電器。因此在測(cè)量高壓線路上的電壓時(shí),盡管一次電壓很高,但二次卻是低壓的,可以確保操作人員和儀表的。工作原理編輯其工作原理與變壓器相同[2],基本結(jié)構(gòu)也是鐵心和原、副繞組。特點(diǎn)是容量很小且比較恒定,正常運(yùn)行時(shí)接近于空載狀態(tài)。電壓互感器本身的阻抗很小,一旦副邊發(fā)生短路,電流將急劇增長(zhǎng)而燒毀線圈。為此,電壓互感器的原邊接有熔斷器,副邊可靠接地,以免原、副邊絕緣損毀時(shí),副邊出現(xiàn)對(duì)地高電位而造身和設(shè)備事故。測(cè)量用電壓互感器一般都做成單相雙線圈結(jié)構(gòu),其原邊電壓為被測(cè)電壓(如電力的線電壓)。
