摘 要

近年来，人们对高压器件的发展应用有了更广泛的关注，伴随着电力系统各方面的飞速发展，无论是对于电磁兼容性的保障，还是对于电压传导干扰的测量，系统都逐步提出了越来越高的要求。通过了解对于一些常规测量标准办法的总结来看，目前对于一些较复杂系统（如高频、高压、大电流系统）的测量方法比较缺少并难以满足测量要求，故对于实现一些复杂系统的传导干扰的测量，保障系统的电磁兼容性，保证电网的安全、稳定、经济运行就显得尤为重要。

论文主要研究了对于高电压宽频传导干扰的测量方法，可以满足对于一些复杂系统中参数的测量，保证电力系统的正常稳定运行。

研究结果表明：本论文设计的电压探头在理想情况以及实际测量中可以满足对于高压高频率干扰信号的测量。

本文的特色：基于传统对于高电压或高频率单独的测量方法，结合了传统测量方法的优点，对于高压高频信号的测量准确，几乎不会出现失真的情况。符合国际上对于测量方法制定的标准，符合国际机构组织对于电磁兼容性保障的要求。并且此项设计可以在实际中解决许多工程问题，对于维护电网的安全稳定运行有极其重要的意义。

Abstract

In recent years, people have paid more attention to the development and application of high-voltage devices. With the rapid development of all aspects of the power system, the system has put forward higher requirements for the protection of electromagnetic compatibility and the measurement of voltage conduction interference.By understanding for some routine measurement standard solution, the end of the current for some of the more complex system (such as high frequency, high voltage, large current system) measurement method is lack and meets the requirement of measurement, so for realizing the measurement of the conducted interference of some complex system, guarantee system of electromagnetic compatibility, to ensure the safe, stable and economic operation of grid is particularly important.

This paper mainly studies the measurement method of high voltage broadband conduction interference, which can satisfy the measurement of parameters in some complex systems and ensure the normal and stable operation of the power system.

The results show that the voltage probe designed in this paper can satisfy the measurement of high voltage and high frequency interference signal in the ideal condition and practical measurement.

Features of this paper: based on the traditional high voltage or high frequency independent measurement method, combined with the advantages of the traditional measurement method, high voltage and high frequency signal measurement accuracy, almost no distortion.In line with the international standards for measurement methods, in line with the requirements of international institutions and organizations for the protection of electromagnetic compatibility.It can solve many practical problems in the project and is of great significance to the operation and protection of the power grid.

Key Words：High voltage broadband; Conducting interference; Voltage probe; Interference measuremen
