摘要
紫外成像技术利用紫外光成像仪接收放电产生的紫外线信号,达到确定电晕位置和强度的目的,并反映电气设备表面电晕放电状态。本文应用紫外成像技术,在±800kV哈密南换流站开关设备现场交流耐压试验中,对恶劣环境下影响试验的强电晕放电进行准确定位和有效评估,弥补了人工目视检查的不足,实现了耐压试验的全过程可控。
Ultraviolet imaging technique uses the UV imager to receive the UV signal generated by discharge,which can determine the position and intensity of the corona discharge and reflect the status of the discharge on the surface of electrical equipment.This paper applies the ultraviolet imaging technology in the AC withstand test of high voltage switchgear of the±800kV Hami Nan Converter Station to position and evaluate the intensive corona discharge that affects the tests under harsh environment,which makes up for the disadvantage of artificial visual inspection and achieves controllability of the whole testing process.
