Abstract

This paper reviews the various testing methods and applications for the inter-turn insulation of dry-type air-core reactor by domestic research and technicians.According to the temperature rise effect in the fault process of dry-type reactor

the diagnosis method of inter-turn insulation defect of dry-type air-core reactor based on temperature rise distribution is proposed.lt is proved that the method is effective by making a temperature-rise prototype and simulating calculation model

carrying out simulation calculation and testing model.This method is validated by the test

disintegration and operation of the back-running reactor

which is applicab le to the operation state diagnosis of dry reactor and the real-time monitoring of the operation state of the important dry reactor in the field conditions.
