| 摘 要： | 在GIS设备绝缘局部放电检测中,各种因素将会产生各种不同的干扰.局部放电信号的测量为GIS内部绝缘的整体情况提供了重要的信息.除了在硬件上采取措施抑制干扰,还可以在软件上采用数字滤波,也可以得到良好的效果.对信号采用软硬件结合的预处理措施达到满意的抑制各种噪声和干扰的效果.同时也给出了采用Maxim公司有源滤波芯片MAX274设计有源滤波器的方法. |

| Abstract: | There are many kinds of disturbances during partial discharge measurement of electric power equipment insulation. The measurement of the partial discharged signal offers important information for insulating whole situation within GIS. Digital filter is a good method for restraining disturbances besides hardware measures. The combinational way of software and hardware to pre-process the receiving ultrasonic signals demonstrates the capacity to suppress noise and interferences. Meanwhile, the application of the active filter MAX274 is introduced ,which is produced by Maxim. |
