由于設(shè)備的起動(dòng)一停止特性，不希望電潛泵循環(huán)運(yùn)行?！翱缇€路”起動(dòng)導(dǎo)致電流波動(dòng)為標(biāo)準(zhǔn)工作電流的5-8倍。這種波動(dòng)能損壞馬達(dá)和電纜，還會(huì)引起線路電壓紊亂。而停車(會(huì)引起較大的電流量和電壓峰值。因此，許多操作者常常不建議使電潛泵設(shè)備更多的起動(dòng)和停車)，除非需要.這就給使用電潛泵帶來(lái)了許多設(shè)計(jì)問(wèn)題。在設(shè)計(jì)問(wèn)題上，若電潛泵選小了，泵一定被拖住使產(chǎn)量降低.若泵尺寸設(shè)計(jì)大了，會(huì)造成油井有停泵的趨勢(shì)。在增加井口回壓來(lái)減小離心泵的排量時(shí)，原采用循環(huán)運(yùn)行。這是不希望出現(xiàn)的。由于施加回壓要帶來(lái)能量的浪費(fèi)，并引起泵內(nèi)止推軸承發(fā)生問(wèn)題而導(dǎo)致過(guò)早的損壞。如果減小電壓或電潛泵采用軟啟動(dòng)顯示出消除循環(huán)運(yùn)行的不利影響，那么電潛泵的設(shè)計(jì)就變得容易的多.泵排量可選為油井排量的25-30%，這樣每天油井生產(chǎn)有足夠的時(shí)數(shù)來(lái)滿足油井排量.目前所使用高電壓起動(dòng)的標(biāo)準(zhǔn)電氣設(shè)備大功率感應(yīng)式馬達(dá)，是一個(gè)電力一機(jī)械“跨線路”起動(dòng)器.它能控制電壓高達(dá)2500V和1000hp的功率，而本身不發(fā)生問(wèn)題.按一下按鈕即可起動(dòng)，它激發(fā)一個(gè)110VAC繼電器，繼而依次接通主電源繼電器.起動(dòng)幾乎是瞬時(shí)的。每當(dāng)使用通常方法進(jìn)行控制起動(dòng)，在常用的星形接三相電的轉(zhuǎn)換線路中。

現(xiàn)在跟大家講講根據(jù)負(fù)載性質(zhì)選擇不同型號(hào)的軟啟動(dòng)器來(lái)選用軟啟動(dòng)器軟啟動(dòng)器選型：目前市場(chǎng)上常見(jiàn)的軟啟動(dòng)器有旁路型軟啟動(dòng)器、無(wú)旁路型軟啟動(dòng)器、節(jié)能型軟啟動(dòng)器等。下面我們來(lái)一一講它們的功能：旁路型軟啟動(dòng)器：在電動(dòng)機(jī)達(dá)到額定轉(zhuǎn)數(shù)時(shí)，用旁路接觸器取代已完成任務(wù)的軟啟動(dòng)器，降低晶閘管的熱損耗，提高其工作效率。也可以用一臺(tái)軟啟動(dòng)器去啟動(dòng)多臺(tái)電動(dòng)機(jī)。無(wú)旁路型軟啟動(dòng)器：晶閘管處于全導(dǎo)通狀態(tài)，電動(dòng)機(jī)工作于全壓方式，忽略電壓諧波分量，經(jīng)常用于短時(shí)重復(fù)工作的電動(dòng)機(jī)。節(jié)能型軟啟動(dòng)器：當(dāng)電動(dòng)機(jī)負(fù)荷較輕時(shí)，軟啟動(dòng)器自動(dòng)降低施加于電動(dòng)機(jī)定子上的電壓，減少電動(dòng)機(jī)電流勵(lì)磁分量，提高電動(dòng)機(jī)功率因數(shù)。軟啟動(dòng)器如何選規(guī)格?根據(jù)電動(dòng)機(jī)的標(biāo)稱功率，電流負(fù)載性質(zhì)選擇啟動(dòng)器，一般軟啟動(dòng)器容量稍大于電動(dòng)機(jī)工作電流，還應(yīng)考慮保護(hù)作用是否完備，例如：缺相保護(hù)、短路保護(hù)、過(guò)載保護(hù)、逆序保護(hù)、過(guò)壓保護(hù)、欠壓保護(hù)等。科恩電氣以誠(chéng)信為根本，以質(zhì)量服務(wù)求生存。</p><div
