摘　　要：基于高斯定理,对旋转式电场仪在特高压交流输电线下交流电场中产生的感应信号进行了详细的理论推导,同时在实验室模拟了旋转式电场仪测量交流电场的工作过程,验证了该电场仪测量交流电场的可行性。这样,可以实现对特高压交直流同走廊输电线路下交流电场和直流电场同时进行实时测量,具有较高的实际应用价值和广阔的应用前景。Based on Gauss＇s law, a detailed derivation of induced signal of field mill in AC electric field genera- ted by UHVAC transmission is provided, and the measurement process of AC field using field mill in the labo- ratory is simulated to verify the feasibility of measurement of electric field under UHVAC power lines using field mill instruments. It can realize the simultaneous measurement of hybrid electric field generated by parallel adjacent erection of UHVAC and UHVDC transmission in the same corridor, so it has great practical applica- tion value and prospect.
