1.可以降低電機(jī)的啟動(dòng)電流，從而減少電容量。 2.減少啟動(dòng)應(yīng)力，可以延長(zhǎng)電動(dòng)氣以及其他的相關(guān)設(shè)備的使用壽命，維修率低。 3.平穩(wěn)的啟動(dòng)和軟停車，都是避免了傳統(tǒng)的啟動(dòng)設(shè)備的喘振問(wèn)題等。 4.完善可靠的保護(hù)功能，能夠有效的保護(hù)電機(jī)以及設(shè)備的安全。 5.同時(shí)還能有效的升降起動(dòng)電流以及配電電容量。 6.多種起動(dòng)模式及寬范圍的電流、電壓等設(shè)定，可適應(yīng)多種負(fù)載情況；淄博科恩軟啟動(dòng)器廠商</p><div style="width:100%;text-align:

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(guò)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(shì)。(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(duì)電動(dòng)機(jī)而言，需要有一個(gè)供電切換過(guò)程:由變頻器供電切換到電網(wǎng)供電.在這個(gè)過(guò)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(wèn)題。簡(jiǎn)而言之.存在切換問(wèn)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)器代理</p><p
