摘　　要：以四角形接线方式与二进二出3/2接线方式为研究对象,计算电气接线中的元件在等效前后对系统可靠性指标的影响,并从实际工程角度分析可靠性指标变化的意义。研究表明,在相同等效原则下,等效前后系统可靠性指标具有一致性,单个元素可靠性指标变化对系统可靠性指标影响程度受到系统拓扑结构和可靠性判据的制约。This article takes quadrangular wiring mode and 3/2 wiring with two inlets and two outlets as research object to calculate impact of elements in electrical wiring on system reliability index before and after equivalence.Furthermore,it analyzes significance of reliability index change in terms of practical engineering.The research indicates that reliability index before and after equivalence is in conformity to each other under the same equivalence principle and the impact of reliability index change of single element on reliability index of the system is restricted by topological structure of the system and criterion for reliability.
