| 摘 要： | 针对传统功率计测量电功率存在线圈电感、电容与金属部分的涡流感应等限制,本文基于布拉格光纤光栅与压电转换器设计了电功率传感器来测量实功率与虚功率.将布拉格光纤光栅粘贴于压电转换器上,构建了动态应变模拟装置.负载电压与负载电流的乘积形成的等效电压施加在压电转换器上使布拉格光纤光栅动态变化,由此测量光栅动态变化所造成的波长改...

| Abstract: | The measurement of power by conventional meters has some limitations due to the inductance and capacitance of coils and the eddy current induction in the metal parts of the meters.Optical fiber gratings are currently being used as sensors for a number of physical quantities such as temperature,strain and pressure;other quantities,such as current and electrical power measurements can be detected by fiber gratings using appropriate transducers.This paper demonstrates an optical fiber sensor using a Fiber Brag... |
