diagnostyka izolacji maszyn elektrycznych
izolacja maszyn elektrycznych - Opis:
- Core sheets insulations faults of electric machines result in eddy currents appearance. The currents flow is a reason of local temperature increasing which can cause wire and sheets insulation degradation. Visual diagnosis of core sheets insulation during the repair is not reliable. Traditional method of diagnosis, based on flux excitation by high intensity current and temperature increasing observation, is time consuming, not very reliable and inconvenient. Measurement of flux leakage on stator teeth surface is fast and reliable method of core sheets insulation diagnostic. This method doesn't require high intensity excitation current. Equipment offered on the market is very expensive and it is most dedicated to diagnose big synchronous generators. Authors invented, constructed and implemented original device dedicated to measure and diagnose of sheets insulations. Whole the system, with the special dedicated software was tested on special parts in laboratory and also in real industrial conditions. Paper shows principle of operation and results of using the system.
