摘　　要：介绍了扩大内桥接线备自投装置的10种运行方式,提出了用解耦法构成扩大内桥接线备自投装置的控制策略,证明了该方法与穷举法运行方式相同。以新的控制逻辑框图形成2个内桥备自投逻辑构成扩大内桥备自投逻辑图(部分)为例,分析了典型运行方式下内桥2个备自投逻辑协同工作来完成典型动作逻辑,证实了解耦法的正确性。分析了穷举法与解耦法的优缺点,建议采用解耦法构成扩大内桥接线备自投装置的控制策略,其牵涉环节少、动作逻辑和动作流程简单方便。Ten operation modes of the bus self-transfer with expansive inner-bridge connection are introduced. The decoupling method of the control strategy for bus self-transfer with expansive inner-bridge connection is presented, and it is proved that its operation modes is the same as that of the exhaustive method. The expansive inner-bridge connection bus self-transfer logic block-diagram is formed by two inner-bridge connection bus self-transfer control logic, which are using new control logic block- diagram. And how to work in coordination by two decoupling inner-bridge connection to complete typical operation logic under the typical operating mode is analyzed, which verifies the correctness of decoupling method. The advantages and disadvantages of the two methods are analyzed, and the decoupling method is recommended for its advantages of less link involved, simple and convenient operation logic and operation process.
