摘要

根据对高压输电线路进行验电操作的实际情况和需求，研究一款可用于10 kV及35 kV输电线路的非接触式交流验电指示器。采用以电磁感应为原理的电场传感器作为感应探头，分析了传感器的测量机制，探究了传感器测量结果的影响因素。利用Maxwell软件对输电导线周围的电场分布情况进行仿真分析，分析不同带电情况下传感器参数对性能的影响，为验电指示器结构设计提供理论指导。对验电器硬件电路进行设计同时设计软件控制系统，制作验电器样机，搭建测试实验回路，对设计制作的验电器进行测试，验证验电器的验电效果。试验结果表明，在高压电场环境下，传感器的感应电压符合电场感应规律，验电器可以定性验电，具有实际意义。

Abstract

According to the actual situation and demand of electric test operation of high-voltage transmission line

a kind of non-contact AC electroscope for 10 kV and 35 kV transmission lines is studied. The electric field sensor with electromagnetic induction as principle is used as the induction probe to analyze the measurement mechanism of the sensor and explore the influencing factors of the sensor measurement results. The Maxwell software is used to simulate the electric field distribution around the transmission line

and the influence of sensor parameters on the performance under different live conditions is analyzed so to provide theoretical guidance for the structural design of the electroscope. The hardware circuit of the electroscope is designed and the software control system is designed at the same time. The the prototype of the electroscope is made

the test experimental circuit is set up to test the prepared electroscope and verify the effect of the electroscope. The test results show that under the high voltage electric field environment

the sensor's induced voltage of the sensor conforms to the law of electric field induction

the electroscope can perform qualitative electric test and has practical significance.
