摘要

笔者基于工程项目研究了牵引变电所真空断路器在线监测中分、合闸时间的确定方法。在断路器分、合闸过程中

在线监测系统分别通过拉线位移传感器和压电式加速度传感器获取动触头的位移信号和断路器的振动信号

然后经过以DSP为核心的数据采集装置和通信网络将信号传至工控机。工控机上的后台管理软件对整个过程中动触头的位移特性和振动能量特点进行综合分析

最终确定分、合闸时间。

Abstract

This paper studies the method of calculating the opening and closing time of on-line monitoring system for the vacuum circuit breaker in traction substations based on engineering project.In the opening and closing process

the on-line monitoring system gets displacement signal of the moving contact through the guyed displacement sensor

and gets vibration signal through the piezoelectric acceleration sensor

then the signal monitored is sent to the industrial personal computer through the data acquisition unit taking DSP as the core and the communication network.After comprehensive analysis of the moving contact’s displacement and vibration energy characteristics by the background management software in the computer

opening and closing time can be determined.
