//維護(hù)簡(jiǎn)單
使用軟啟動(dòng)器啟動(dòng)電動(dòng)機(jī)時(shí),晶閘管的輸出電壓逐漸增加,電動(dòng)機(jī)逐漸加速,直到晶閘管全導(dǎo)通,電動(dòng)機(jī)工作在額定電壓的機(jī)械特性上,實(shí)現(xiàn)平滑啟動(dòng),降低啟動(dòng)電流,避免啟動(dòng)過(guò)流跳閘。待電機(jī)達(dá)到額定轉(zhuǎn)數(shù)時(shí),啟動(dòng)過(guò)程結(jié)束,軟啟動(dòng)器自動(dòng)用旁路接觸器取代已完成任務(wù)的晶閘管,為電動(dòng)機(jī)正常運(yùn)轉(zhuǎn)提供額定電壓,以降低晶閘管的熱損耗,延長(zhǎng)軟啟動(dòng)器的使用壽命,提高其工作效率,又使電網(wǎng)避免了諧波污染。軟啟動(dòng)器同時(shí)還提供軟停車功能,軟停車與軟啟動(dòng)過(guò)程相反,電壓逐漸降低,轉(zhuǎn)數(shù)逐漸下降到零,避免自由停車引起的轉(zhuǎn)矩沖擊
