想的電機(jī)保護(hù)器？理想的電機(jī)保護(hù)器不是功能**多，也不是所謂**技術(shù)的，而是應(yīng)該滿足現(xiàn)場實(shí)際需求，做到經(jīng)濟(jì)性和可靠性的統(tǒng)一，具有較高的性能價(jià)格比。根據(jù)現(xiàn)場的實(shí)際情況合理地選擇保護(hù)器的種類、功能，湖南長沙軟啟動(dòng)器同時(shí)考慮保護(hù)器安裝、調(diào)整、使用簡單方便，更重要的是要選擇高質(zhì)量的保護(hù)器。水泵啟動(dòng)方式有直接啟動(dòng)，降壓啟動(dòng)，軟啟動(dòng)和變頻啟動(dòng)四種，直接啟動(dòng)一般適合小功率的電機(jī)，我們一般只在15kw以下的泵上使用，價(jià)格便宜；降壓啟動(dòng)是星—三角轉(zhuǎn)換啟動(dòng)，就是啟動(dòng)是分兩次加速才達(dá)到額定轉(zhuǎn)速的，一般在，價(jià)格適中；軟啟動(dòng)是逐漸增加到額定轉(zhuǎn)速的，對泵的沖擊很小，價(jià)格比較高，一般是降壓啟動(dòng)的3倍；高級的是變頻啟動(dòng)，除了有軟啟動(dòng)的優(yōu)點(diǎn)外，還可以設(shè)定在任意轉(zhuǎn)速工作，對節(jié)能降耗有效果。在關(guān)閉泵出口閥，打開泵進(jìn)口閥，并能確保水泵“自灌”(液位高于泵的進(jìn)口的管道條件下，水泵的啟動(dòng)程序是：啟動(dòng)電機(jī)，待電機(jī)正常運(yùn)行時(shí)，緩緩打開出口閥，使電流慢慢加大。但在無人操作(開閥)，又是自動(dòng)啟泵，且管道直徑與長度大(管道內(nèi)的水質(zhì)量會(huì)很大)，如電機(jī)快速啟動(dòng)，要迅速推動(dòng)大質(zhì)量的水加速(如同火車要很快加速)，會(huì)使電機(jī)啟動(dòng)電流很大。淄博科恩軟啟動(dòng)器選購</p><div

src="http://tyunfile.71360.com/UpLoadFile/2019/4/12/14/636906757443826248_keendianqi_9094734.jpg"></div><p 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型變壓器也不是沒有道理的，下面來說一下使用R型變壓器的好處。 1.效率高 R型變壓器鐵芯無切割，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，因此在使用過程中不會(huì)發(fā)出噪音來。 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，在使用過程中無需采取防范措施來防止漏磁的現(xiàn)象。 4.符合安全的標(biāo)準(zhǔn) 由于它的獨(dú)特設(shè)計(jì)，將初級與次級的骨架分開，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的安全標(biāo)準(zhǔn)</p><p> 軟啟動(dòng)器1.無沖擊電流，軟啟動(dòng)器在啟動(dòng)電動(dòng)機(jī)時(shí)，通過逐漸增大晶閘管導(dǎo)通角，使電動(dòng)機(jī)啟動(dòng)電流從零線性上升至設(shè)定值。2.恒流啟動(dòng)，軟啟動(dòng)器可以引人電流閉環(huán)控制，使電動(dòng)機(jī)在啟動(dòng)過程中保持恒流，確保電動(dòng)機(jī)平穩(wěn)啟動(dòng)。3.根據(jù)負(fù)載情況及電網(wǎng)繼電保護(hù)特性選擇，可自由地?zé)o級調(diào)整至比較好的啟動(dòng)電流。4.電動(dòng)機(jī)停機(jī)時(shí)，傳統(tǒng)的控制方式都是通過瞬間停電完成的。但有許多應(yīng)用場合，不允許電動(dòng)機(jī)瞬問關(guān)機(jī)。例如:高層建筑、大樓的水泵系統(tǒng)，如果瞬間停機(jī)，會(huì)產(chǎn)生巨大的“水錘”效應(yīng)，使軟起甚至水泵損壞。為減少和防止“水錘”效應(yīng)，需要電動(dòng)機(jī)逐步停機(jī)，即軟停車，采用軟啟動(dòng)器能滿足這一要求。在泵站中，應(yīng)用軟停車技術(shù)可避免泵站的“拍門”損壞，減少維修費(fèi)用和維修工作量。5.軟啟動(dòng)器輕載節(jié)能?；\型異步電動(dòng)機(jī)是感性負(fù)載，在運(yùn)行中，定子線圈繞組中的電流滯后于電壓。如電動(dòng)機(jī)工作電壓不變，處于輕載時(shí)。功率因數(shù)低;處于重載時(shí)，功率因數(shù)高。在輕載時(shí)，軟啟動(dòng)器通過降低電動(dòng)機(jī)端電壓，提高功率因數(shù)，減少電動(dòng)機(jī)的鋼耗、鐵耗，達(dá)到輕載節(jié)能的目的;負(fù)載重時(shí)，則提高電動(dòng)機(jī)端電壓，確保電動(dòng)機(jī)正常運(yùn)行。</p><div

軟啟動(dòng)器，應(yīng)用先進(jìn)的軟件設(shè)計(jì)方法和的硬件技術(shù)，采用晶閘管相移技術(shù)，使加到電動(dòng)機(jī)上的電壓按某一規(guī)律慢慢達(dá)到全電壓，通過設(shè)置適當(dāng)?shù)目刂茀?shù)，可以使電動(dòng)機(jī)的轉(zhuǎn)矩和電流與負(fù)載要求得到較好的匹配。同時(shí)，通過軟件與硬件的配合，對軟啟動(dòng)器本身、電動(dòng)機(jī)、負(fù)載提供的保護(hù)。一般來講，電動(dòng)機(jī)功率的選擇總是大于比較大負(fù)載要求，其結(jié)果是電動(dòng)機(jī)很少在額定功率下運(yùn)行，經(jīng)常處于輕載或變載的情況，能量嚴(yán)重浪費(fèi)。軟啟動(dòng)在運(yùn)行時(shí)，首先保持輸出額定電壓，以保證電動(dòng)機(jī)和負(fù)載在加速后進(jìn)入穩(wěn)定狀態(tài)；保持一段很短時(shí)間之后，自動(dòng)進(jìn)入節(jié)電運(yùn)行階段。其獨(dú)有的節(jié)電控制軟件自動(dòng)負(fù)載變化，通過不斷對電流和功率因數(shù)的綜合計(jì)算，進(jìn)行實(shí)時(shí)調(diào)節(jié)、更新觸發(fā)角，控制輸出電壓，降低勵(lì)磁電流，提高功率因數(shù)，實(shí)現(xiàn)節(jié)電。淄博科恩軟啟動(dòng)器選購</p><p style="text-indent:25px">淄博科恩軟啟動(dòng)器制造廠家</p><p> 由于啟動(dòng)電流小.因此需要的配電容量也是所有啟動(dòng)方式中**小的。(4)采用變頻器控制的電動(dòng)機(jī)具有良好的動(dòng)態(tài)、靜態(tài)性能。由于變頻器本身就是用于電動(dòng)機(jī)調(diào)速的裝置.因此，控制電動(dòng)機(jī)的轉(zhuǎn)速是其基本功能.啟動(dòng)過程可以實(shí)現(xiàn)任意控制，理論上可以人為隨意設(shè)置任何啟動(dòng)速度曲線。這是其他方式所不具備的優(yōu)勢。(5)用變頗器拖動(dòng)多臺(tái)電動(dòng)機(jī)啟動(dòng)時(shí)，即使被拖動(dòng)電動(dòng)機(jī)的容量有較大懸殊，也不會(huì)形響其啟動(dòng)性能。(6)啟動(dòng)完成后，對電動(dòng)機(jī)而言，需要有一個(gè)供電切換過程:由變頻器供電切換到電網(wǎng)供電.在這個(gè)過程里會(huì)出現(xiàn)諸如變頻器安全、電流沖擊、轉(zhuǎn)速變化等問題。簡而言之.存在切換問題。所謂軟切換就是安全、平穩(wěn)地切換。艾克威爾是專業(yè)專業(yè)軟起動(dòng)器生產(chǎn)廠家，主要生產(chǎn)高低壓軟起動(dòng)器，資質(zhì)齊全，使用更安心。淄博科恩軟啟動(dòng)器制造廠家</p><p
