| 摘 要： | 基于脉冲极性鉴别方法,设计并实现了抗干扰能力很强的局部放电测试仪。根据平衡回路中试样局部放电和外部放电极性不同的特点,通过逻辑判断能够在电磁干扰很强的环境中测量试样内部放电,并且能直观反映放电量的大小和放电的试样。

| Abstract: | Based on pulsic polarity discrimination method,the partial discharge test device with strong anti-interference capability was designed and realized.According to the difference of the polarity between the sample partial discharge in the balancing circuit and the external discharge,through the logical judge the internal partial discharge can be tested in an environment with severe electromagnetic interference.The amount and the pattern of discharge can be reflected and viewed directly. |
