摘要: 該文在故障子網(wǎng)絡(luò)等效電流矢量的基礎(chǔ)上,討論了子網(wǎng)絡(luò)的測(cè)試特性,得到了容差條件下故障子網(wǎng)絡(luò)判斷的必要條件。該方法在診斷過(guò)程中可對(duì)各子網(wǎng)絡(luò)同時(shí)做出診斷,不但能加快診斷過(guò)程,而且可消除誤差傳遞性的問(wèn)題,對(duì)于容差故障診斷具有理論和實(shí)際意義。Abstract: In this paper,the test property of fault subnetworks has been discussed based on the fault subnetwork equivalent current vector, and the essential condition for determinting fault subnetworks has been given. Using this method, every subnetwork may be diagnosed at the same time independently. The method not only may quicken diagnosis process, but also may solve the error transfer question. Thus, this paper should have theoretical and practical significance for tolerance fault diagnosis.
