摘要
提出一种基于霍尔效应行波测距前端模拟量采集系统。霍尔效应的传感器属于磁电式传感器的一种,目前具有动态特性好、线性度高、精度高、频带宽以及尺寸小、外围电路简单等优良特性。并为实现高频暂态行波的高速同步采集和快速处理提供了强有力的保证。
This paper presents a traveling wave fault location front-end analog acquisition system which based on Hall effect. Hall-effect sensor is a magnetic sensor.Currently,it has many excellent features,for example,the good dynamic performance, high linearity,high precision,wide frequency band,and small size,simple external circuit and so on.And to achieve high-frequency transient traveling wave speed synchronous acquisition and fast processing provides a strong guarantee.
