REXROTH SF-A3.0068.030-00.018

為了隔絕、改進輸入電流及減小諧波，如今悉數(shù)的中壓“直接變頻”器都不是實在的直接變頻，其輸入側(cè)都裝有輸入變壓器，這種配備短時刻內(nèi)不會改動。已然輸入側(cè)有變壓器，變頻器和電機的電壓就沒有必要和電網(wǎng)相同，非用十kV和6kV不行，功率2500kW以下電壓能夠不跨過3kV，因而就有了變頻器和電機的合理電壓等級疑問。

　　200kW～800kW以下的變頻調(diào)速宜選用380V或660V電壓等級。它線路簡略，技能老到，牢靠性高，dv/dt小，報價廉價。仍以560kW電機為例，630kW660V的低壓變頻器約35萬，而同容量6000V中壓變頻器約90萬。完畢的辦法有低-低，低-高，高-低和高-低-幾種辦法。因為電機，變壓器的報價遠(yuǎn)低于變頻器，即便替換電機、變壓器也合理。
