故障診斷和防止連鎖性故障的途徑
FAULT DIAGNOSIS AND THE APPROACH TO PREVENT CHAIN-FAULT
-
摘要: 本文討論了一種故障診斷技術(shù)以及決定b分支網(wǎng)絡(luò)中故障元件的位置和數(shù)值的方法。它是將電路的正常狀態(tài)作為伴隨電路與故障狀態(tài)比較,通過(guò)對(duì)某些可測(cè)節(jié)點(diǎn)或分支的幾次測(cè)量來(lái)完成的。 主要內(nèi)容:(1)內(nèi)部故障的外部映射;(2)故障狀態(tài)的擴(kuò)散;(3)連鎖性故障的防止。

Abstract: In this paper, there is discussed a fault diagnosis technique and related method of calculation to determine the position and value of a fault component which happens to be in a b-branches network. This technique based on comparing the fault circuit with the adjoint circuit (which is named to indicate the original circuit in normal state) requires only a few measurements on some of accessible nodes or branches.Three main concepts are discussed in this paper: (1) The discussion about the external mapping of the internal faults; (2) The discussion about the extension of a fault state; (3) The discussion about the approach to proventing chain-fault. -
