電動(dòng)機(jī)的啟動(dòng)指標(biāo)啟動(dòng)（startion）是指電動(dòng)機(jī)從靜止?fàn)顟B(tài)開始轉(zhuǎn)動(dòng)起來．直至達(dá)到穩(wěn)定運(yùn)行。對干任何一臺電動(dòng)機(jī)．在啟動(dòng)時(shí)．都有下列兩個(gè)基本的要求。啟動(dòng)轉(zhuǎn)矩要足夠大．只有Tｎ>TL時(shí)．電動(dòng)機(jī)才能改變原來的靜止?fàn)顟B(tài)．拖動(dòng)生產(chǎn)機(jī)械運(yùn)轉(zhuǎn)。一般要求Tn≥()TL,Tn越大于TL．啟動(dòng)過程所需要的時(shí)間就越短。啟動(dòng)電流不要超過允許范圍。對三相異步電動(dòng)機(jī)來說．由干啟動(dòng)瞬間s=1,旋轉(zhuǎn)磁場與轉(zhuǎn)子之間的相對運(yùn)動(dòng)速度很大．轉(zhuǎn)子電路的感應(yīng)電動(dòng)勢及電流都很大．所以．啟動(dòng)電流遠(yuǎn)大干額定電流．在電源容量與電動(dòng)機(jī)的額定功率相比不是足夠大時(shí)．會(huì)引起輸電線路上電壓降的增加．造成供電電壓的明顯下降．不*影響了同一供電系統(tǒng)中其他負(fù)載的工作，而且會(huì)延長電動(dòng)機(jī)本身的啟動(dòng)時(shí)間。此外在啟動(dòng)過干頻繁時(shí)，還會(huì)引起電動(dòng)機(jī)過熱。在這兩種情況下．就必須設(shè)法減小啟動(dòng)電流．下面分別介紹籠型和繞線型異步電動(dòng)饑的啟動(dòng)方法．異步電動(dòng)機(jī)啟動(dòng)籠型異步電動(dòng)機(jī)的直接啟動(dòng)直接啟動(dòng)又稱為全壓啟動(dòng)．就是將電動(dòng)機(jī)的定子繞組直接加上額定電壓啟動(dòng)．直接啟動(dòng)電流雖然很大．但因啟動(dòng)時(shí)間很短．而且隨著轉(zhuǎn)子轉(zhuǎn)動(dòng)起來后。電流很快減小．只要啟動(dòng)不過于頻繁．不致引起電動(dòng)機(jī)過熱。 </p><p> 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，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。科恩電氣重信譽(yù)、守合同，嚴(yán)把產(chǎn)品質(zhì)量關(guān)，熱誠歡迎廣大用戶前來咨詢考察，洽談業(yè)務(wù)！</p><div

從長期來看：變頻軟起將會(huì)成為軟起動(dòng)器（西馳分級變頻軟起動(dòng)器）的主流。各種形式的降壓軟起動(dòng)將與星三角起動(dòng)等技術(shù)一起歸并為傳統(tǒng)的起動(dòng)技術(shù)。隨著變頻器價(jià)格的逐漸下降，可靠性的進(jìn)一步提高，也隨著技術(shù)人員水平的提高，**為軟起動(dòng)而選用變頻器將不再會(huì)被人們認(rèn)為是一種。變頻軟起動(dòng)勝出的根本原因是：它可以在限流（起動(dòng)電流不超過電機(jī)額定電流值）的同時(shí)獲得大的起動(dòng)轉(zhuǎn)矩，可以實(shí)現(xiàn)包括軟停止在內(nèi)的各種起動(dòng)功能。對于**為軟起動(dòng)而制作的變頻器而言，應(yīng)在起動(dòng)完成后使變頻器脫電，使電動(dòng)機(jī)直掛電網(wǎng)。這樣做的目的是節(jié)能，消除無謂的損耗。這種操作應(yīng)該在安全的不引起電流沖擊的條件下完成，或者叫做軟切換。軟切換的可能步驟是“先脫（電）后掛（網(wǎng)）”或“先掛后脫”，軟切換應(yīng)該在基本上不增加硬件（例如軟切換電抗器）的條件下主要靠軟件完成。淄博科恩軟啟動(dòng)器批發(fā)價(jià)格</p><p
