style="text-indent:25px">電機(jī)軟啟動器的主接線有三種方法主要是在線型、旁路型、內(nèi)置旁路型。 1.在線型：一切軟發(fā)動器的控制器都有電動機(jī)過載保護(hù)，當(dāng)軟啟動器在線運行時對電機(jī)進(jìn)行過載保護(hù)，不要加裝熱過載繼電器。由于經(jīng)過可控硅后的電流諧波電流非常大，所以不能加裝電子式熱過載繼電器，否則會使系統(tǒng)不能正常的工作。 2.旁路型：對于軟啟動器上口的接觸器的作用和在線運行方式下作用相同的情況下不能再重復(fù)。這邊注意的熱繼電器，把它安方在旁路接觸器的下口，不通電流，尤其是電子熱繼電器，淄博科恩軟啟動器廠商，由于經(jīng)過軟啟動器后電流諧波很大能干擾電子熱繼電器誤動作而使電機(jī)停車，淄博科恩軟啟動器廠商。

軟起動器具有軟起動、軟停止、泵控制功能、定時低速運行等多種功能，因此在工業(yè)、民用建筑領(lǐng)域的動力設(shè)備控制中具有傳統(tǒng)降壓起動器不可比擬的優(yōu)越性。三相異步電動機(jī)有很多優(yōu)點，但也有兩個致命的弱點：一是啟動性能差；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，有兩個典型的產(chǎn)品改善了異步電動機(jī)這兩個弱點，一是變頻器，二是軟啟動器。變頻器改善異步電動機(jī)的調(diào)速性能；軟起動在起動時間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、無級地加速。同時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脫扣器在電機(jī)起動時誤跳閘。過載保護(hù)功能一般電機(jī)的過載保護(hù)是通過熱元件來實現(xiàn)的，熱元件在電動機(jī)起動過程中很難避開電機(jī)的起動電流而產(chǎn)生誤動作。為避免誤動，用戶常加大熱元件的動作電流，因而使得過載保護(hù)的靈敏度不夠，使過載保護(hù)形同虛設(shè)。而軟起動器內(nèi)置的過載保護(hù)功能是根據(jù)起動負(fù)荷的輕重(即起動時間的長短)來選擇不同的脫扣特性曲線，以避免在起動過程中誤跳。由于它的過載保護(hù)是可編程的，軟啟動器廠家從而為用戶提供了更大的靈活性。淄博科恩軟啟動器廠商科恩電氣累積點滴改進(jìn)，邁向優(yōu)良品質(zhì)！</p><div
