style="text-indent:25px">大家都知道在軟啟動(dòng)器中都會(huì)有一個(gè)R型變壓器，R型變壓器主要是采用取向性高磁導(dǎo)率硅鋼帶制成的，同時(shí)具有體積小、重量輕、效率高、漏磁小等特點(diǎn)得到了普遍的應(yīng)用。軟啟動(dòng)器在控制電路時(shí)需要使用低壓直電流，但是又不能直接使用開(kāi)關(guān)電源，所以在使用時(shí)需要一種隔離電源變壓器，于是軟啟動(dòng)器就看上了R型變壓器了。軟啟動(dòng)器選擇R型變壓器也不是沒(méi)有道理的，下面來(lái)說(shuō)一下使用R型變壓器的好處。 1.效率高 R型變壓器鐵芯無(wú)切割，損失小，并且使用***的材料和緊湊的結(jié)構(gòu)，可以把鐵芯與繞組之間的距離降底，這樣效率可以達(dá)到百分之90以上。 2.無(wú)噪音由于R型變壓器是使用***低損耗的材料，并且具有均勻圓形截面和連續(xù)的繞線，電阻的損耗和產(chǎn)熱都非常的低，磁致伸縮應(yīng)力很容易被吸收，因此在使用過(guò)程中不會(huì)發(fā)出噪音來(lái)。 3.漏磁小 R型變壓器的鐵芯都是繞線極勻衡，因此漏磁是非常小的，在使用過(guò)程中無(wú)需采取防范措施來(lái)防止漏磁的現(xiàn)象。 4.符合安全的標(biāo)準(zhǔn) 由于它的獨(dú)特設(shè)計(jì)，將初級(jí)與次級(jí)的骨架分開(kāi)，并且具有良好的絕緣性。由于阻燃材料制成的互相分離的骨架這樣可以滿足我國(guó)的安全標(biāo)準(zhǔn)淄博科恩軟啟動(dòng)器廠家報(bào)價(jià)</p><div style="width:100%;text-align:

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。“跨線路”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。 </p><p>在很多從業(yè)人員和非從業(yè)人員的眼中，軟啟動(dòng)器行業(yè)都是夕陽(yáng)產(chǎn)業(yè)。那么軟啟動(dòng)器是否是夕陽(yáng)西下，日落西山了呢？我們首先來(lái)看一個(gè)圖這是軟啟動(dòng)器近10年來(lái)的一個(gè)搜索數(shù)據(jù)的曲線除了2015年異軍突起，其他的時(shí)間都保持著平穩(wěn)發(fā)展的趨勢(shì)，沒(méi)有說(shuō)是特別的下降。即便是今年的**影響下，搜索量也是與往年相比保持個(gè)持平的狀態(tài)，可以說(shuō)，低壓軟啟動(dòng)器行業(yè)雖然沒(méi)有太高的提升，但是還是保持著一個(gè)平穩(wěn)發(fā)展的態(tài)勢(shì)。再來(lái)看高壓端高壓軟啟動(dòng)器的發(fā)展則是肉眼可見(jiàn)的。從19年開(kāi)始高壓軟啟動(dòng)器的搜索量開(kāi)始快速增長(zhǎng)，這是夕陽(yáng)產(chǎn)業(yè)該有的態(tài)勢(shì)嗎。很明顯不是，那么為什么還是很多人唱衰軟啟動(dòng)器行業(yè)呢。首先，國(guó)產(chǎn)變頻器從18年開(kāi)始價(jià)格大量下浮，導(dǎo)致很多人覺(jué)得軟啟動(dòng)器的生存空間被壓縮了。但是這些人卻沒(méi)想到，大部分變頻器能替代的地方基本上已經(jīng)在過(guò)去已經(jīng)替代光了。剩下的一些場(chǎng)景*需啟動(dòng)，監(jiān)測(cè)，而不需要調(diào)速，根本用不上變頻器。同時(shí)雖然變頻器價(jià)格下浮，但是價(jià)格還是遠(yuǎn)比軟啟動(dòng)器貴很多?，F(xiàn)在市場(chǎng)上的低壓軟啟動(dòng)器，種類偏多，大抵分為外置旁路軟啟動(dòng)器、內(nèi)置旁路軟啟動(dòng)器和在線式軟啟動(dòng)器。其中外置旁路軟啟動(dòng)器，把接觸器外置，啟動(dòng)之后直接切旁路運(yùn)行。</p><div

變頻器和軟啟動(dòng)器是兩種完全不同用途的產(chǎn)品。變頻器主要是用于需要電動(dòng)機(jī)調(diào)速的地方，因此也被稱為變頻調(diào)速器，其輸出不但改變電壓而且同時(shí)改變頻率。變頻器具備所有軟啟動(dòng)器和其他啟動(dòng)控制裝置的功能，且啟動(dòng)特性上較之其他電動(dòng)機(jī)啟動(dòng)裝置有比較大的優(yōu)勢(shì).因此完全可以用作電動(dòng)機(jī)的軟啟動(dòng)控制。但之所以目前在電動(dòng)機(jī)的啟動(dòng)控制領(lǐng)城軟啟動(dòng)器仍占據(jù)主要位置.是由于變頻器固有的一些劣勢(shì)，且短期內(nèi)很難克服.只有克服了這些劣勢(shì)之后.變頻器才有可能取代軟啟動(dòng)器。變頻器的特點(diǎn)：(1)啟動(dòng)轉(zhuǎn)矩大，功率因數(shù)高。因?yàn)殡妱?dòng)機(jī)的功率因數(shù)與工作頻率有關(guān)，在電動(dòng)機(jī)低速運(yùn)行時(shí)工頻電源下的功率因數(shù)遠(yuǎn)低于低頻電源下的功率因數(shù)。變頻器可以控制電動(dòng)機(jī)從低頻起步.且在整個(gè)啟動(dòng)過(guò)程中在接近額定電流的條件下始終保持比較高的功率因數(shù)和接近額定轉(zhuǎn)矩的輸出轉(zhuǎn)矩。(2)輕載或空載條件下.或啟動(dòng)期間采取減載卸載等措施時(shí).變頻器容量可以比電動(dòng)機(jī)容量小。當(dāng)然，啟動(dòng)完成后變頻器需要退出運(yùn)行。(3)啟動(dòng)電流小。變頻器一電動(dòng)機(jī)拖動(dòng)系統(tǒng)允許的啟動(dòng)時(shí)間可以很長(zhǎng)。因?yàn)樵谶@期間，電動(dòng)機(jī)電流可以不超過(guò)電動(dòng)機(jī)額定電流，因此，不論是變頻器、電動(dòng)機(jī)還是其他元器件均沒(méi)有超常地發(fā)熱。
