摘　　要：现代电器设备中 ,电路的故障诊断、可测性和可靠性设计在电力系统安全可靠运行中起着重要的作用。引用数字电路的方法对现代电趋设备电路进行故障诊断 ,可测性、可靠性设计是一种全新的思路。本文提出一种新的方法对现代电器设备电路进行公式抽取 ,通过建立系统元件的节点 节点关联矩阵 ,并对其不断进行降价 ,直到得出电路的逻辑表达式。这种方法可以在微机上实现 ,使电路公式的抽取简单。The fault diagnosis, testability and reliability design of circuits in modern switchgear and controlgear play an important role in the secure running of electrical power system. Applying digital circuits to the fault diagnosis. testability and reliability design of circuits in modern switchgear and controlgear is a new idea. In this paper a new method of formula extracting from circuit topology of modern switchgear and controlgear was introduced. In order to obtain the logic expression of the circuits finally, the node node related matrix of components in the system should be built and its steps should be reduced to two. This method can be realized by microcomputer, making it easy to extract formula from circuits. It is of great significance to the digital processing of modern electrical apparatus circuits.
