摘要
以某220kV同塔双回交流输电线路为例,研究分析了多种工况下停运线路的感应电压。并利用ATP-EMTP建立仿真模型,得出各种工况下的感应电值;通过对仿真结果的分析可以看出大多数220kV的感应电压值已经超过了人体能承受的电压的安全值,对人身安全构成威胁,故在电力施工作业时须严格遵守安全作业规程。
Take the same tower double circuit AC transmission line of 220kV as an example, the induced voltage of off- the-line under many working conditions is studied and analyzed. ATP-EMTP is used to setup an analogue model, obtai- ning induced voltage values under various working conditions. By the analysis of simulative results, it can be seen that most induced voltage values of 220kV have been more than voltage safety value that human body can bear, It constitutes a threat to human body, safety, so people must strictly observe safe working codes for electric power working location.
