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.

Key words： mechanical characteristic generator circuit breaker (GCB) displacement sensor grating encoder
