Abstract

The embodiment of the invention provides a device for detecting a moisture content of dielectric oil. The device comprises a terahertz generator, a sample tester, a terahertz detector and an upper computer, wherein the terahertz generator matches the terahertz detector, and the sample tester is arranged between the terahertz generator and the terahertz detector; the sample tester comprises a sample platform and a two-dimensional movable platform, the sample platform is provided with a transparent sample bottle used for holding the dielectric oil, the sample platform is located on the focal point plane between the terahertz generator and the terahertz detector, and the sample platform is connected with the two-dimensional movable platform which controls the sample platform to move on the focal point plane; the upper computer is correspondingly and electrically connected with the terahertz generator, the terahertz detector and the two-dimensional movable platform. According to the device, through the moisture content of the dielectric oil detected by a terahertz imaging technology, nondestructive testing can be obtained, and the device has the advantages of being high in accuracy, high in degree of automation, and friendly to environment.

Description

technical field [0001] The present application relates to the technical field of transformers, in particular to a device for detecting moisture content of insulating oil. Background technique [0002] The oil-immersed transformer is filled with insulating oil, which can play the role of insulation, heat dissipation and arc extinguishing. Monitoring the insulating oil is an important means to ensure the normal operation of the transformer. Moisture is one of the important indicators for monitoring the quality of insulating oil. The source of moisture in transformers is mainly the intrusion of moisture in the atmosphere into the oil from the outside of the equipment, the infiltration of moisture absorbed by the cellulose of the insulating material into the oil, or the aging and decomposition of cellulose. Moisture gets into the oil. During the operation of the transformer, as long as there is a small amount of moisture in the insulating oil, it will cause great harm to the e...
