style="font-size:14px;">（1）電壓型變頻器</span> </p> <p> <span style="font-size:14px;">電壓型變頻器特點(diǎn)是中間直流環(huán)節(jié)的儲能元件采用大電容，負(fù)載的無功功率將由它來緩沖，直流電壓比較平穩(wěn)，直流電源內(nèi)阻較小，相當(dāng)于電壓源，故稱電壓型變頻器，常選用于負(fù)載電壓變化較大的場合。</span> </p> <p> <span style="font-size:14px;">（2）電流型變頻器</span> </p> <p> <span style="font-size:14px;">電流型變頻器特點(diǎn)是中間直流環(huán)節(jié)采用大電感作為儲能環(huán)節(jié)，緩沖無功功率，即扼制電流的變化，使電壓接近正弦波，由于該直流內(nèi)阻較大，故稱電流源型變頻器（電流型）。電流型變頻器的特點(diǎn)（優(yōu)點(diǎn)）是能扼制負(fù)載電流頻繁而急</span><span

style="font-size:14px;">3、變頻器與負(fù)載的匹配問題；</span> </p> <p> <span style="font-size:14px;">1)電壓匹配；變頻器的額定電壓與負(fù)載的額定電壓相符。</span> </p> <p> <span style="font-size:14px;">2)電流匹配；普通的離心泵，變頻器的額定電流與電機(jī)的額定電</span><span style="font-size:14px;">流相符。對于特殊的負(fù)載如深水泵等則需要參考電機(jī)性能參數(shù)，以蕞大電流確定變頻器電流和過載能力。</span> </p> <p> <span style="font-size:14px;">3)轉(zhuǎn)矩匹配；這種情況在恒轉(zhuǎn)矩負(fù)載或有減速裝置時有可能發(fā)生。<strong>【云南永樂科技有限公司主要銷售維修變頻器、ABB變頻器、英威騰變頻器、東力變頻器、施耐德變頻器、西門子變頻器等等，如有需求，歡迎大家來電咨詢！】</strong></span>
