随着电力系统自动化程度的不断提高,人们环保意识的不断增强,电力系统的电磁兼容问题愈来愈引起人们的重视,电力系统中的高压电源、电力电子装置、高压、超高压和特高压输电线路等作为强电部分与电力系统内部及外界的通信、继电保护、计算机、电子设备等弱电部分都存在着电磁干扰,有效地抑制和防护电磁干扰,准确地测量各种干扰源的强度和分布,磁场传感器起着非常关键的作用。本文介绍国外90年代初研制的一种新型传感器——Z—元件。
With the continuous improvement of the degree of automation of power system, people’s awareness of environmental protection is constantly increasing, and the electromagnetic compatibility problem of power system attracts more and more attention. High-voltage power supply, power electronic devices, high voltage, ultra high voltage and UHV power transmission in the power system Lines and other parts as the strong part of the power system with the internal and external communications, relay protection, computers, electronic equipment and other weak parts of the existence of electromagnetic interference, effectively suppress and protect electromagnetic interference, accurately measure the intensity of various interference sources and Distribution, magnetic field sensor plays a very crucial role. This article introduces a new type of sensor developed abroad in the early 1990s - Z-element.
