高压带电设备电压等级非接触识别方法研究
Research on voltage level non-contact identification method for high voltage live equipment
摘要
Abstract
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.关键词
