高压带电设备电压等级非接触识别方法研究
现有的接触式验电需分电压等级使用不同的验电设备，非接触式验则无法识别电压等级，而电压等级直接决定了带电作业安全距离。电压等级的非接触识别对验电设备的非接触验电、近电预警有重要意义。文章基于距离和电场测量，利用多项式回归分析理论研究了一种电压等级的非接触识别方法。通过采集10kV、35kV和110kV三种电压等级周围的电场和距离数据，分别求取三种拟合函数，进行多项式回归分析，从而实现电压等级的判别。同时研制了电压等级非接触识别装置，对该方法进行识别验证，实验结果证明能够对三种电压等级实现较好地识别。...

| Abstract_FL | The existing contact type inspection needs to be divided into voltage levels to use different inspection equipments,and the non-contact test can not identify the voltage level,and the voltage level directly determines the safe distance of live operation.Non-contact identification of voltage level is important to non-contact inspection and early warning of electric equipment.Based on the distance and measurement of electric field,a method of non-contact identification of voltage level is studied by using the theory of polynomial regression analysis.By collecting the electric field and distance data of 10 kV,35 kV and 110 kV,the three fitting functions are obtained respectively,and the polynomial regression analysis is carried out to realize the discrimination of the voltage grade of the three kinds of voltage.At the same time,a voltage level non-contact identification device is developed to identify and validate the proposed method.The experimental results show that the three voltage levels can be well recognized. |
