Abstract

The invention relates to a device and method for simulating the moisture migration process in a high-voltage oil-paper insulating casing. A sealed container with a pipe body and an oil conservator structure, the simulated container has an internal cavity for filling transformer oil and a stem for winding insulating paper; the drying device is used to fill the simulated container with dry gas to pass The gas replacement method dries the gas above the transformer oil in the simulated container; the dripping and oil extraction device is used to drip water into the simulated container in different ways to simulate the damp state of the bushing in different situations; the temperature and humidity detection device includes The inner and outer temperature and humidity sensors and the display module are electrically connected through data lines. The device and method are beneficial for simulating the water migration process in the high-voltage oil-paper insulating bushing, and the operation is simple and the experiment cost is low.

Description

technical field [0001] The invention relates to the technical field of high-voltage engineering, in particular to a device and method for simulating the water migration process in a high-voltage oil-paper insulating bushing. Background technique [0002] Most of the high-voltage power transformer bushings are oil-paper capacitor bushings. The oil-paper capacitor bushing is composed of oil pillow, upper and lower porcelain sleeves, capacitor core and grounding flange. Among them, the capacitor core is made of insulating paper, and the capacitor core and transformer oil form an oil-paper composite insulation, which has excellent electrical performance. The casing oil conservator adopts a fully sealed structure to avoid erosion caused by large gas production. In order to avoid excessive internal pressure due to oil expansion when the temperature increases, a certain volume of air is left on the upper part of the oil conservator to act as a buffer. [0003] The oil-paper two-...
