一种不停盘车的发电机转子接地定位装置
By connecting the generator rotor magnetic poles and the main shaft through a carbon brush holder, and utilizing the built-in power supply and detection module, the grounding fault point can be measured and located while the generator rotor is in a non-stop turning state. This solves the problem that existing technologies cannot locate faults while the generator rotor is in a non-stop turning state, and achieves efficient fault detection and online monitoring.

AI Technical Summary
Technical Problem
Existing generator rotor grounding fault location devices cannot measure and locate faults without stopping the generator turning, which may lead to main shaft deformation and unit damage.
Method used
A carbon brush holder is used to connect the generator rotor magnetic poles and the main shaft. The built-in power supply and detection and processing module are used to measure and locate the grounding fault point when the generator rotor is not rotating. The carbon brush replaces the ordinary winding or clamp electrical connection method.
Benefits of technology
It enables the measurement and location of grounding faults without stopping the generator turning, reducing detection waiting time and cost, and developing online monitoring capabilities.
