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100Hz,验证了所采用的设计方法的可行性。
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.
