Abstract

The invention discloses an insulating oil or oil-paper insulation aging test device, which comprises an aging box body arranged over a heating module and used for storing insulating oil or oil paper; a temperature and humidity detection module arranged in the aging box body and connected with a temperature and humidity control module and used for detecting temperature and humidity data in the aging box body and sending the data to the temperature and humidity control module; the temperature and humidity control module used for receiving the temperature and humidity data in the aging box body and controlling the temperature and humidity in the aging box body through a heating module and a humidification module based on the temperature and humidity data; and a circulation module used for circulating the insulating oil in the aging box body. The device is closer to actual operation situations compared with single-factor heating aging or humidity influence, thereby improving experiment data reliability and providing data for study on electric heat ageing of transformer oil-paper insulation; and meanwhile, the provided technical scheme is simple to realize, low in tool cost, and high in practicality and repeatability.

Description

technical field [0001] The invention relates to the technical fields of engineering dielectric and electrical engineering, and more specifically, relates to an aging test device and a use method for insulating oil or oil-paper insulation. Background technique [0002] The safe operation of the transformer is directly related to the safety of the power grid. Once a serious fault occurs in the transformer, it will not only damage the equipment, but also cause power interruption. Transformer insulation aging is the main factor causing transformer problems, accounting for about 80% of the overall faults. The performance of the oil and paper in the transformer will deteriorate with the operation time of the equipment, and the deterioration rate mainly depends on the operating temperature and the humidity in the system. The important insulating medium of power equipment in field operation is transformer oil, and the aging of transformer oil-paper insulation is mainly caused by th...
