摘要
文章首先分析高频局部放电(以下简称局放)的原理,其次探讨高频局放信号的特征和传播与衰减规律,最后阐述高频局放带电指示器的设计,包括总体架构设计、信号处理电路设计和信号处理算法与软件系统开发。所设计的高频局放带电指示器能够实现对设备带电状态的精准监测,可以快速响应设备带电状态的变化,为电力系统的安全监测和故障预警提供了有效手段。
This paper first analyzes the principle of high frequency partial discharge(hereinafter referred to as partial discharge),then discusses the characteristics of high frequency partial discharge signal and the law of propagation and attenuation,and finally expounds the design of high frequency partial discharge live indicator,including the overall architecture design,signal processing circuit design,signal processing algorithm and software system development.The designed high frequency local discharge indicator can realize the accurate monitoring of the equipment's charging state,and can quickly respond to the change of the equipment's charging state,which provides an effective means for the safety monitoring and fault warning of the power system.
