無紙記錄儀和無線通訊技術(shù)的有機(jī)結(jié)合，有效的解決了油田地域十分分散，而又急需解決數(shù)據(jù)遠(yuǎn)傳和自動控制問題。本文向你介紹彩色無紙記錄儀在國內(nèi)某大型油田采油集、輸中的應(yīng)用一例?，F(xiàn)場情況編輯油田油井十分分散，往往離采油廠幾公里甚至幾十公里，因此，輸送及天然氣的管線遍布油區(qū)各地，要想實(shí)時(shí)每口井以及各個(gè)區(qū)域的采油/氣量十分困難，多年來，各大油田的采油站、聯(lián)合站、運(yùn)銷處等大都采用各采油站填寫報(bào)表的形式統(tǒng)計(jì)每天每口井以及各個(gè)區(qū)域的采油/氣量，然后通過累加的月產(chǎn)量，這樣的不但要花費(fèi)大量的人力和物力，很易出錯(cuò)，而且在時(shí)間上也嚴(yán)重滯后，采油廠、油田很難動態(tài)每口井甚至每個(gè)區(qū)域的采油情況，對突發(fā)事件難以做出迅速反應(yīng)。

因此為了輸出電壓誤差，反饋電阻的取值應(yīng)該很大。由于3V工作電壓時(shí)，MAX4544的導(dǎo)通電阻僅為120Ω，因此開關(guān)MAX4544引入的誤差電壓很小，即使低輸出電壓也是如此。當(dāng)使能升壓變換器，且其輸出電壓超過MAX810的復(fù)位門檻電平并經(jīng)過復(fù)位后，MAX810的輸出將由高變低，使Q1導(dǎo)通，連通負(fù)載。同時(shí)，MAX810輸出的低電平使MAX4544的COM端與NC端（常閉端）接通，使得反饋電阻由Q1的源極切換至Q1的漏極，從而允許從遠(yuǎn)離變換器的負(fù)載端對輸出電行調(diào)節(jié)。上述MAX4544的開關(guān)也把MAX810的輸入端從Q1的源極切換到Q1的漏極，這樣一來，MAX810可以用來監(jiān)測負(fù)載是否過載。

智能軟啟動器利用三對晶閘管的電子開關(guān)特性，通過啟動器中的微處理器，控制其觸發(fā)脈沖的遲早來改變觸發(fā)角的大小，而晶閘管觸發(fā)角的大小，又可改變晶閘管的導(dǎo)通時(shí)間，從而終改變加到定子繞組的三相電壓的大小。異步電動機(jī)定子調(diào)壓的特點(diǎn)是，電動機(jī)轉(zhuǎn)矩近似與定子電壓的二次方成正比，電動機(jī)的電流和定子電壓成正比，因此，電動機(jī)的啟動轉(zhuǎn)矩和初始電流的可以通過定子電壓的控制來實(shí)現(xiàn)。而電動機(jī)定子電壓又是通過晶閘管的導(dǎo)通角來控制的，所以不同的初始相角可實(shí)現(xiàn)不同的端電壓，以不同的負(fù)載啟動特性。在電動機(jī)啟動中，晶閘管的導(dǎo)通角逐漸增大，晶閘管的輸出電壓也逐漸，電動機(jī)從零開始加速，直到晶閘管全導(dǎo)通，啟動完成，從而實(shí)現(xiàn)電動機(jī)的無級啟動。
