单通道双谱紫外电晕放电检测方法

UV Corona Discharge Detection Way of Single Channel & Dual-Spectrum

为了防止电晕产生的危害,电力部门需要实时地检测并定位电晕放电故障点。而用于电晕检测的传统双通道紫外检测设备结构复杂,图像处理难度大,研发成本高。基于日盲紫外检测技术,设计了一种新结构的单通道双谱紫外检测系统,其结构简洁,图像处理简便,研发成本较低。系统以PC为主要硬件架构,实现单片机驱动步进电机控制前端滤光片切换,从而能对故障点进行准确的定位,并通过仿真实验验证了系统定位故障点的准确性。

In order to prevent the harm of corona,the power sector needs to detect and locate point of failure with corona discharge in real time.However,the traditional dual-channel UV detection equipment used for corona detection has complex structure,difficulty for its image processing,and high costs in research and development.A new structure of UV detection system based on solar blind UV detection technology with single channel and dual-spectrum is put forward,it is a simple-structure,easy in image processing and low in research and development costs.The system uses PC as main hardware architecture and makes MCU drive a stepper motor to switch front-end filter.In this way,the system can exactly locate the point of failure.And the experiments prove the system location accuracy of the fault point.
