员 工 岗 位 培 训 手 册
电气运行技术问答
（网控篇）
发电运行分公司电气编写组
前 言
为创建学习型企业，根据《电气运行规程》及CBE岗位培训手册，精选出符合生产实际的内容汇编成册，其中包括填空、巡检操作、事故处理、二次回路、专业基础及电气安全六部分；二次回路及专业基础试题的选编，不但使员工对业务知识知其然，而且知其所以然，起到了融会贯通的作用。
鉴于《电业安全工作规程》的修编及部分安全知识的零散性，为解决员工收集安全资料的困难，在赵志刚编写的电气安全试题基础上，结合变电运行生产实际，改编附在后面，部分来自新版《安规》，部分来自口碑相传几十年的生产实际，有很强的实用价值。
编写过程中班长金作岩组织得力，全班参与，可以说本书是网控班全体员工智慧的结晶。
主要编写人员：金作岩、战淑华，宋玉兰、解艳杰。 本书由李国怀策划审定，金作岩、李洪波编辑整理。 定稿前经全班再次审核，准确性再次提高。
在此，谨向参与编写、编审的全体人员表示感谢！是你们的辛勤劳动使全体员工找到了学习捷径，提高了业务水平，为安全生产打下了坚实基础。 由于时间仓促，不妥之处在所难免，希望在使用中提出宝贵意见，为下次修编提供有利依据。
