摘要

阐述了电容型设备状态在线监测与故障诊断系统的组成和监测内容

对现有的介质损耗因数监测方法进行了分析比较。详细分析了电容型设备状态在线监测中应注意的几个问题

提出了要进一步提高传感器的性能

容性设备在线监测与故障诊断技术要密切跟踪一些新兴数学工具在其他领域的研究成果。着重指出了在介质损耗因数监测方面的研究重点要从理论上克服电压谐波、电网频率波动、非同步采样与非整周期采样等因素的综合影响进行新算法的研究。要改变以往重实用化而忽视基础理论研究的思维误区

在今后的一段时间里应当在基础理论方面进行大量深入的研究。

Abstract

Composition and monitoring content of condition monitoring and faults diagnosis are described in this paper.Some existing methods of dielectric loss are analyzed and compared.Some problems needing attention are analyzed in detail.The performance of sensor should be improved.The fault diagnosis technology should be closely associated with some new mathematical tools.It is emphatically pointed out that the research emphasis is studying on new algorithm comprehensively considering eliminating harmonic influence

frequency fluctuating

asynchronous sampling and non-integer period sampling

and so on.Thinking mode of laying stress on practicality and ignoring basic research should be changed.Basic theory should be done thorough research in the future.
