抑制变压器截波过电压的仿真分析

随着我国经济的发展,用电量迅速增长,同时,配电网络不断延伸,配电变压器不断增多,而保证配电变压器的正常运行是十分重要的.配电变压器在运行中除了长期经受工作电压的作用外,还会遭受暂态过电压的作用.暂态过电压作用时间虽然较短,但其幅值很高,而且在变压器绕组上分布不均匀,因而对变压器的主绝缘和纵绝缘都有严重威胁.雷电冲击电压...

Simulated Analysis of the Controlling Chopping Overvoltage of the Transformer

Along with the distributing network extension,the distributing transformerts are continuously increased.Normal operation for the distributing transformer is very important.The distributing transformer not only undergoes the working voltage in operation,but transient overvoltage effect.The transient overvoltage is short,but its amplitude is high,the winding distribution on the transformer is nonuniform,so it has serious meance to the major insulation and minor isulation of the transformer.Lighting surge volt...
