電機(jī)停機(jī)時(shí)，傳統(tǒng)的控制方式都是通過(guò)瞬間停電完成的.但有許多應(yīng)用場(chǎng)合，不允許電機(jī)瞬間關(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)，使管道，甚至水泵遭到損壞.為減少和防止“水錘“效應(yīng).需要電機(jī)逐漸停機(jī).即軟停車，采用軟啟動(dòng)器能滿足這一要求，淄博科恩軟啟動(dòng)器經(jīng)銷商.在泵站中.應(yīng)用軟停車技術(shù)可遇免泵站的“拍門“損壞，減少維修費(fèi)用和維修工作量.，淄博科恩軟啟動(dòng)器經(jīng)銷商。<span

從長(zhǎng)期來(lái)看：變頻軟起將會(huì)成為軟起動(dòng)器（西馳分級(jí)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(guò)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(duì)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(wú)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)器型號(hào)</p><div

軟起動(dòng)器具有軟起動(dòng)、軟停止、泵控制功能、定時(shí)低速運(yùn)行等多種功能，因此在工業(yè)、民用建筑領(lǐng)域的動(dòng)力設(shè)備控制中具有傳統(tǒng)降壓起動(dòng)器不可比擬的優(yōu)越性。三相異步電動(dòng)機(jī)有很多優(yōu)點(diǎn)，但也有兩個(gè)致命的弱點(diǎn)：一是啟動(dòng)性能差；二是調(diào)速性能差。隨著電力半導(dǎo)體技術(shù)的發(fā)展以及大功率晶體管在工業(yè)控制領(lǐng)域里的應(yīng)用，有兩個(gè)典型的產(chǎn)品改善了異步電動(dòng)機(jī)這兩個(gè)弱點(diǎn)，一是變頻器，二是軟啟動(dòng)器。變頻器改善異步電動(dòng)機(jī)的調(diào)速性能；軟起動(dòng)在起動(dòng)時(shí)間ts內(nèi)，電機(jī)的端電壓從設(shè)定的初始值逐漸增至滿壓，電機(jī)平滑、無(wú)級(jí)地加速。同時(shí)ts可調(diào)節(jié)(通常在60s之間),這有利于與低壓斷路器之間的配合，防止低壓斷路器的瞬時(shí)脫扣器在電機(jī)起動(dòng)時(shí)誤跳閘。過(guò)載保護(hù)功能一般電機(jī)的過(guò)載保護(hù)是通過(guò)熱元件來(lái)實(shí)現(xiàn)的，熱元件在電動(dòng)機(jī)起動(dòng)過(guò)程中很難避開電機(jī)的起動(dòng)電流而產(chǎn)生誤動(dòng)作。為避免誤動(dòng)，用戶常加大熱元件的動(dòng)作電流，因而使得過(guò)載保護(hù)的靈敏度不夠，使過(guò)載保護(hù)形同虛設(shè)。而軟起動(dòng)器內(nèi)置的過(guò)載保護(hù)功能是根據(jù)起動(dòng)負(fù)荷的輕重(即起動(dòng)時(shí)間的長(zhǎng)短)來(lái)選擇不同的脫扣特性曲線，以避免在起動(dòng)過(guò)程中誤跳。由于它的過(guò)載保護(hù)是可編程的，軟啟動(dòng)器廠家從而為用戶提供了更大的靈活性。
