摘要:: 在大庆油田新一联35/10 kV变电所的微机自动化改造工程中，为节省投资，只更换控保屏，而其他设备则利旧处理使用。要把新建微机综合自动化保护装置接入老式设备保护回路中，存在着辅助结点数量不够、回路配置不合理、回路误动作等问题。针对施工中遇到的这些问题进行分析，并制订了具体改线措施，顺利地完成了改造任务。
In construction process of computer automatization alteration project of Xinyiliang 35/10 kV transformer substation of Daqing Oilfield,only the control and protection unit is replaced but other devices are reutilized with some treatments in order to save investment.there are problems in connecting the new computer integrated automation device into the protection circuit of old equipment,such as inadequate number of assistant nodes,unreasonable loop configuration and wrong loop action.Such typical problems appearing in the construction are analyzed and specific measure of line realignment is put forward,thus the alteration task is successfully completed.
