电抗器L和被试品电容C组成的串联谐振都有一个固定的谐振频率F=1/(2π√L·C)当试验频率等于这个频率时,该电路发生谐振。
通过这个原理,由调频电源提供电源送给励磁变压器,经过励磁变压器变压成中压加上L和被试品电容C上。通过改变调频电源输出频率,使回路处于串联谐振状态,再调节调频电源输出电压,使试品上电压达到所需要的电压值。","CompanyName":"宝应县高电电力设备制造厂","CompanyID":"72048","MarketPrice":"29800","PsOrder":"0","PgID":"0","MaxOrder":"0","CityID":"95","City":"扬州市","Address":"扬州市","PropertysValue":"","HitNumber":"330","FrontShow":"0","IsCharges":"0","Year":"8","StarNum":"2","UpdateAndClientSort":"6587623","StandUrl":"/st72048","UpdateTime":"2015/7/11 17:43:28","TodayIsUpdate":"0","AttType":"0","AttState":"0","AttAddType":"0","IsSeoCreate":"","IsOnlinePay":"0","MinPrice":"0.00","MaxPrice":"0.00","ClassID":"1723","productonlinetime":"1900/1/1 0:00:00","OnLineDate":"1900/1/1 0:00:00","DownLineDate":"1900/1/1 0:00:00","BrandPicDomin":"","BrandPicName":"","BrandProperty":"","PBrandID":"0","IsHadVideo":"0","VideoTime":"0"}]
