光纤式GIS局部放电检测装置的研究

传统的GIS局部放电检测的方法主要是电测法和声测法,这些方法很容易受到现场环境的干扰。本文通过检测GIS内电晕产生的紫外光实现其内部局部放电的在线监测,介绍了非接触式紫外光功率检测法的基本原理及基于该方法的在线装置的基本构成和实现方法,并使用该实验装置对高压放电进行了模拟实验。结果表明,该装置具有很高的灵敏度和响应速度,具有很好的应用前景。

Study on Optical Fiber GIS Partial Discharge Detection Device

The traditional GIS partial discharge detection method is electrical measurement method and acoustic measurement method, The disadvantage of these methods is that the intensive envi- ronmental condition disturbances make the results incorrect. A method is developed for on-line monitoring the partial discharge in GIS by detecting the ultraviolet radiation that emitted from the corona. The principle of UV pulse power is introduced, and the basic structure and realizing method of the on-line detector is proposed. Experimental result indicates that the detector has high sensitivity and quick response speed. The proposed on-line detector has bright application future.
