【Abstract】 This paper proposed the concept of “digital processing” for the circuits of modern switchgear. With the related matrix of circuits devices and its element states, the logical functions, which are based on every branch or key link even on the whole circuit in the switchgear circuits, will be obtained. Sequentially, a method extracting formula from circuit topograghy was introduced, which is used to analyze logical functions of the circuits of switchgears. It is of great significance in designing and analyzing the reliability and measurability for the circuits of switchgears. On analysis for the operation performance of circuit devices, the circuit model of devices for extracting formula was given as well.更多还原
