UV Corona Discharge Detection Way of Single Channel & Dual-Spectrum
Tao Bo-hao · Measurement & Control Technology · 2012
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.
