Test and calculation method for judging turn-to-turn insulation damage characteristics of dry-type air-core reactor

The invention discloses a test and calculation method for judging turn-to-turn insulation damage characteristics of a dry-type air-core reactor, system equipment and the reactor apply equivalent inductance, a reactor finite element simulation calculation equivalent inductance model is built according to the actual model and size structure of the reactor, and the equivalent inductance before and after a turn-to-turn insulation fault of the reactor is obtained; comparing and verifying with the actual inductance value of the reactor; a high-frequency pulse oscillation voltage generator is actually developed on site to test the reactor, and is compared with a voltage waveform obtained by a built high-frequency pulse oscillation method for performing an inter-turn insulation fault simulation electromagnetic simulation calculation model on the dry-type air-core reactor; and reducing the equivalent inductance value of the reactor in the model to simulate the turn-to-turn short circuit fault of the reactor, obtaining
