【中文摘要】 局部放电测量是目前测试电力设备特性、发现设备内部缺陷、预防设备故障的一种非常有效的手段。为满足现代电力企业的需求,超高频法、超声波法、油色谱法等许多局部放电在线检测技术得以发展,并在现实中得到应用。本文介绍了北京市电力公司主变压器局部放电在线检测技术的应用研究,对局部放电的测量技术进行了分析,积累了大量数据、样本和经验,给出了技术应用的两个典型案例,介绍了DMS超高频和TECHIMP高频两种先进技术方法的典型典型图谱。建立多种局部放电在线检测方法合理搭配的联合诊断方法,为未来电力设备在线检测方法发展提供指导。
【英文摘要】 Partial discharge measurement is currently the test characteristics of electrical equipment and found that the internal defects in equipment to prevent equipment failure of a very effective means.Power enterprises to meet the needs of modern, ultra-high frequency method,ultrasonic method,chromatography and many other oil-line partial discharge detection techniques can be developed and applied in reality.This paper introduces the main transformer power companies,Beijing-line partial discharge detection techniques applied research,the measurement of partial discharge analysis techniques,and accumulated a large amount of data,sample and experience,given the application of the two typical cases,introduced DMS UHF and VHF TECHIMP two methods of advanced technology,a typical pattern of a typical.The establishment of a wide range of online partial discharge detection methods combined with a reasonable diagnostic method for the future of power equipment to provide online guidance to the develo.pment of detection methods.
