Abstract

The invention discloses a device and method for reducing dielectric loss by supplementing a passivating agent into deteriorated insulating oil, and the device comprises an oil drum which is used for receiving the deteriorated insulating oil in a transformer; a first pipeline, wherein the far end of the first pipeline is connected with a sampling valve at the bottom of the transformer; a three-wayjoint, wherein a first joint of the three-way joint is connected with the near end of the first pipeline through a first electromagnetic valve; a second pipeline, wherein the far end of the second pipeline is connected with a second joint of the three-way joint through a second electromagnetic valve and is arranged in the oil drum; and a third pipeline, wherein the far end of the third pipeline isconnected with the third connector of the three-way connector through a third electromagnetic valve, the far end of the third pipeline is arranged in the oil drum, and a circulating pump is arrangedon the third pipeline. According to the device and the method for reducing the dielectric loss by supplementing the passivator into the deteriorated insulating oil, the deteriorated insulating oil canbe rapidly repaired, the whole process is automatically operated, the repairing efficiency is high, the effect is good, the dielectric loss of a transformer body is greatly reduced, the reliability of safe operation of the transformer is improved, and the service life of the transformer is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and relates to a transformer oil recycling method, in particular to a device and method for reducing dielectric loss by supplementing degraded insulating oil with a passivating agent. Background technique [0002] The transformer oil widely used in the power sector, after a period of use, due to the normal aging of the transformer oil and the generation of particulate carbon due to arc extinguishing, has many impurities in the oil, and the oil color is turbid and becomes deteriorated. The used transformer oil is discarded. To a certain extent, degraded insulating oil has become a "hazardous waste" defined by the relevant national environmental protection regulations. cause serious harm. [0003] At present, the recovery and treatment of deteriorated insulating oil at home and abroad generally adopts the method of adding passivation agent for repair. First, the deteriorated insul...
