| 摘 要： | PWM变频调速已成为异步电机最主要的调速方法,变频器在50Hz以下,设定V/F为一恒定值,也即恒力矩输出.变频器在拖动大客量风机、水泵之类负戴中,经常会发生过载(或过流)跳闸,究其原因,是母线电压瞬时跌落造成此现象,变频器的"AVR功能"是解决这一问题的关健.

| Abstract: | e frequency conversion with PWM is the main timing way of asynchronism motor now. It can chang the frequence blow 50Hz and set up V/ F as a the invariablenes value, also namely invariablenes moment export. In dragging the strong capacity such as breeze machine or the pump load, Transducer usually take place over loading (or over current) triping. It is because of suddently falling off of the generatrix voltage, the "AVR' Function of Transducer is a key to resolve this problem. |

| Keywords: | er loading (or over current) voltage motion of generatrix AVR function |
