【摘要】早期备用电源自动投入装置在应用中,当工作电源消失时,备用电源自投装置不具备动作条件造成负荷损失；当动作条件满足时,仍存在闭锁条件造成其不能正确动作.结合110kV内桥接线变电站实际运行方式,找出造成失电的各种原因及对应表现,通过现场多次试验,发现进线开关、桥开关备自投拒动原因及存在动作死区的原因,对不同运行方式下装置的充电、闭锁条件及动作逻辑进行了改进.结果表明改进后装置运行良好.%For some engineers working in operation or production fields in the industry of electric power, valuable applied technologies from them are difficult to be put out on high-level journals due to their poor ability to place emphases when writing a paper. Targeting some typical problems in drafting a paper, the author elaborates the potential changes of readers and their difference with structural units. The abstract in Chinese serves search and spreading, whereas the abstract in English serves the internationalization of China-based technologies. Introduction should exhibit the depth of research. Theory and method may be followed closely by professionals in the same field. Result and conclusion should reveal fully the innovations. The author suggests determining structure and emphases in accordance with readers and application purposes. Papers with higher spreading
