Power-up hot oil circulation method before converter transformer insulation test

The invention relates to a power-up hot oil circulation method before a converter transformer insulation test, and belongs to the technical field of transformer tests. According to the technical scheme, after the converter transformer is installed, in the transformer oil circulation process, a transformer body is electrically heated; the speed of oil passing through the coil of the converter transformer is increased through electric heating, particles, water and gas of the coil and the coil oil duct are taken away, and meanwhile the speed of transformer oil soaking of an insulating part in the converter transformer is increased. The method has the beneficial effects that moisture, gas and impurities in the converter transformer body and oil are effectively removed by adopting a power-on hot oil circulation mode, and meanwhile, insulation oil permeation is accelerated, so that the internal insulation strength of the converter transformer is improved. 本发明涉及一种换流变绝缘试验前的加电热油循环方法，属于变压器试验技术领域。技术方案是：换流变压器安装完成后，变压器油循环
