摘　　要：带电作业是保障电网安全运行的重要措施,但也给作业人员带来了危险,因此开展了对临近电施工作业中安全距离预警系统的研制。首先提出基于D-dot的非接触式电场探测技术与数字信号传感单片机集成技术,进行电场强度的测量与处理修正,测试证明取得了良好效果。然后建立吊塔带电作业有限元模型,得到不同作业环境的临界电场阈值,完成多场景安全距离的确定。最后研制一套临近电施工作业安全距离预警系统,保障电网安全运行。Charged operation is an important measure to ensure the safe operation of the power grid,but it also brings danger to the operators.In view of this,the present study carries out the development of safety distance warning system for near-electricity construction operation.First the non-contact electric field detection technology based on D-dot and the integration technology of digital signal sensing microcontroller are proposed for the measurement and processing correction of electric field strength,and the test proves that satisfactory results have been achieved.Then a finite element model of electric work with crane tower is established to get the critical electric field thresholds of different operating environments and complete the determination of safety distance in multiple scenarios.Finally,a set of safety distance warning system for near-electricity construction work is developed to ensure the safe operation of power grid.
