脉冲变压器 螺旋渐开式绕组 局部放电 重复频率 pulse transformer helix-involute winding local-discharge repetition frequency
摘要
介绍了1.2 MV脉冲变压器的设计方法,采用螺旋渐开式绕组逐渐增大绕组对磁芯的绝缘距离,用ANSYS程序模拟脉冲变压器中的场强分布情况,最大场强不超过18 kV/mm。通过实验研究有效解决了绕组对绝缘支撑的局部放电现象,得到了1.2 MV的高压脉冲输出,单次运行时间达到1 min,重复频率100 Hz,验证了所采用的设计方法的可行性。
Abstract
This paper summarized the design method of a 1.2 MV pulse transformer,which adopted the helix-involute winding to enlarge the isolation distance between the winding and the magnetic core. The numerical simulation of ANSYS showed that the maximum electric field was less than 18 kV/mm in this transformer. The local-discharge phenomena of the winding to the insulator were solved through experimental research. The derived pulse transformer could meet the following design specifications:1.2 MV output voltage,100 Hz repetition frequency and 1 min single runtime.
