【实用工具】典型局放椭圆波形python演示(附源码及可执行exe)
周末用python写了一个椭圆波形的演示程序，波形参照于DL/T 417-2019 电力设备局部放电现场测量导则附录B 基本图谱。好几种图差不多，选择了5种进行演示。源码已在文末免费分享，有兴趣的可以自己修改源码参数模拟其它波形变化情况。同时，小程序也更新增加了椭圆波形模拟，大家可点击体验。
波形生成：基于高斯包络+正弦振荡脉冲，叠加基线椭圆与背景噪声
模拟放电：单气隙放电 / 表面-多气隙放电/ 界面气隙放电悬浮放电/尖板放电
实时刷新：参数调整后波形即时更新，类型切换自动复位参数
核心参数：源码自定义参数全覆盖
  • 试验电压（0~20kV，源码可调）
  • 起始放电电压（可手动调节）
  • 相位整体偏移
  • 背景干扰水平
  • 幅值增长模式（随电压增长 / 到达起始电压后恒定）
  • 脉冲幅度、计数、相位宽度等波形细节参数
适用场景：电力局放检测教学、培训课件制作、图谱比对演示、报告配图生成，快速输出标准椭圆图谱。
