摘要
真空断路器灭弧室触头是断路器实现分闸合闸的关键部件,需定期检查,但常规人工检测方法费时费力。经过对真空断路器灭弧室机械结构特点与动作过程的研究,设计出一种基于ARM处理器的触头磨损度检测系统,此系统由安装在断路器端的从机和安装在控制室电脑上的主机适配器组成,系统使用搭载ARM1176JZF-S处理器的S3C6410芯片、AD3812模块、W-DCD5位移传感器、4432系列射频无线模块等器件实现了在机房使用一台PC机或手机短信对多台真空断路器灭弧室触头磨损进行远程检测与控制。经测试,系统检测误差低于0.78%。系统检测精度高,使用方便实时性好,可靠性强,大大减少了以往的触头检测工作量。
The contact is the key parts of vacuum interrupter. After observing the design of vacuum interrupter contact , designed an contact abrasion detect system with ARM processor on the structure of the vacuum interrupter. This system uses S3C6410 chip with ARM1176JZF-S processor on it,W-DCD5 displacement sensor, AD3812 3G module, 4432 RF wireless series module and other devices to achieve the function that use one PC in control room or cellphone to monitoring the abrasion of many vacuum interrupter in the distance. We confirm that the system error of detection is less than 0.78%.And this system also has features as follows： high accuracy, good real-time, reliability. Greatly reducing the contact detection workload.
