摘　　要：利用图解法对非线性振荡回路中电流变化时 ,感性负载、容性负载电压的变化特性进行了分析 ,指出产生铁磁谐振过压原因 。The characteristic of varied voltage under inductor load and capacitor load with the change of current is analyzed with the aid of graphic method.The reason of ferromagnetic overvoltage because of resonance is indicated.The over voltage is alleviated with the installation of resonance absorber in the practice and a good result is achieved.
