描述

高壓變頻器是一種串聯(lián)疊加性高壓變頻器，即采用多臺單相三電平逆變器串聯(lián)連接，輸出可變頻變壓的高壓交流電。按照電機學的基本原理，電機的轉(zhuǎn)速滿足如下的關(guān)系式：n=（1一s）60f/p=n?！粒?一s）（P：電機極對數(shù)；f：電機運行頻率;s:滑差）從式中看出，電機的同步轉(zhuǎn)速n。正比于電機的運行頻率（n。=60fp），由于滑差s一般情況下比較?。?-0．05），電機的實際轉(zhuǎn)速n約等于電機的同步轉(zhuǎn)速n。，所以調(diào)節(jié)了電機的供電頻率f，就能改變電機的實際轉(zhuǎn)速。電機的滑差s和負載有關(guān)，負載越大則滑差增加，所以電機的實際轉(zhuǎn)速還會隨負載的增加而略有下降。
