Abstract
The invention discloses a large axial flow pump unit alternating current withstand voltage detection method, which is based on the following power equipment: a voltage regulator, an experimental transformer, a protection water resistor, an electric reactor, an ammeter, an alternating current and direct current voltage divider, a current transformer and a high-voltage grounding rod. And the corona condition and the corresponding voltage value are observed and recorded. According to the invention, the purpose of carrying out corona and AC withstand voltage tests on the stator winding can be realized, whether the anti-corona layer at the end part of the stator winding and the winding insulation have defects can be detected, and the detection process is based on operation steps, so that the whole detection process is safe, reliable and high in efficiency.
