故障诊断和防止连锁性故障的途径
FAULT DIAGNOSIS AND THE APPROACH TO PREVENT CHAIN-FAULT
-
摘要: 本文讨论了一种故障诊断技术以及决定b分支网络中故障元件的位置和数值的方法。它是将电路的正常状态作为伴随电路与故障状态比较,通过对某些可测节点或分支的几次测量来完成的。 主要内容:(1)内部故障的外部映射;(2)故障状态的扩散;(3)连锁性故障的防止。

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. -
