Abstract

An online transformer oil medium loss processing device, including a transformer, the oil inlet solenoid valve of transformer 1 sequentially passes through a primary filter, a heater, an atomizing device, an oil-water separator, a negative pressure adsorption tank, a two-way gear pump, and a positive pressure adsorption Tank, third-stage filter and oil return solenoid valve of the transformer are connected; there is a second manual valve between the oil inlet solenoid valve and the primary filter, a first manual valve between the third-stage filter and the transformer, and a second manual valve. The pipeline between the manual valve and the primary filter is connected through the pipeline between the neutral solenoid valve and the first manual valve and the third-stage filter. When the transformer oil dielectric loss treatment device is working, the pressure difference between the oil inside and outside Under the action of the inlet, it enters the primary filter for filtration. After the oil is heated, the oil and gas are separated, and the water is discharged. The oil enters the negative pressure adsorption tank for adsorption. The oil is heated in the pipeline and seeps into the positive pressure adsorption tank for adsorption. The oil is filtered by a three-stage filter and flows back to the transformer body, which has the advantages of online processing.

Description

technical field [0001] The invention relates to the field of transformer oil medium, in particular to an on-line transformer oil medium loss processing device. Background technique [0002] The energy loss caused by transformer oil under the action of an electric field is called the dielectric loss of transformer oil, which is usually expressed by the dielectric loss tangent tgδ. [0003] Measuring the dielectric loss tangent tgδ of insulating oil can sensitively reflect the aging degree of insulating oil under the influence of electric field, oxidation, sunlight, high temperature and other factors, and can also sensitively find out that when the insulating oil contains water or other impurities are mixed, the The generated polar impurities and charged colloidal substances gradually increase. Therefore, the tgδ test of transformer insulating oil is an important electrical characteristic test. [0004] Power transformer is the key and important equipment in the power system...
