| 摘 要： | 综合相对测量法能克服绝对测量法的不足,有效提高介质损耗角的在线测量精度,目前研究仅限于2到3台同相电容型设备的综合相对测量法的应用,不具普遍性。本文介绍了综合相对测量法的基本原理,以3台和4台同相设备的综合相对测量法的应用为例,利用归纳方法,给出N(N≥3)台设备中任意i(1≤i≤N)台设备的故障诊断矩阵,为综合相对测量法的使用提供了依据。根据阈值诊断和模糊数学理论,提出了基于综合相对测量法的两种故障诊断方法及影响其正确诊断的几个因素,为综合相对测量法的实际使用提供了思路。

| Abstract: | Synthetic relative measuring method not only overcomes the shortcomings of absolute measuring method but also greatly improves the accuracy of dielectric loss angle measurement.However,researches nowadays only focus on the application of synthetic relative measuring method based on two or three pieces of capacitive equipment,which does not have the characteristic of generality.The principle of synthetic relative measuring method is given.The example of application for synthetic relative method based on thre... |
