摘要 发电机断路器（GCB）在运行操作过程中会产生强烈的工作振动,这对GCB机械特性在线监测的核心传感器——位移传感器的安装及稳定运行构成了极大挑战。为解决这一难题,本文设计一种非接触式位移传感器,以实现对GCB设备位移数据的可靠采集。该传感器采用非接触的分体式设计,有效降低了传感器运动部分的质量,进而大幅削弱了振动对传感器的影响。寿命试验表明,所设计的非接触式位移传感器具有较长的使用寿命和较强的工作可靠性。

Abstract ：The generator circuit breaker (GCB) generates intense working vibrations during operation, which poses a significant challenge to the installation and stable operation of the displacement sensor, the core sensor for the online monitoring of GCB mechanical characteristics. To address this issue, this paper designs a non-contact displacement sensor to reliably collect displacement data of GCB equipment. This sensor adopts a non-contact split design, effectively reducing the mass of the sensor’s moving parts and significantly weakening the impact of vibrations on the sensor. Life tests show that the non-contact displacement sensor designed in this paper has a long service life and strong working reliability.
