Dielectric loss reducing and decolorizing treatment method for transformer deteriorated oil

Abstract

The invention discloses a treatment method for reducing dielectric loss and decolorizing transformer deteriorated oil. The treatment method comprises the following specific steps: S1, selecting optimal process conditions for decolorizing the transformer deteriorated oil by utilizing a four-factor three-level orthogonal experimental method; s2, a corresponding container is selected according to the optimal process condition, and the transformer deteriorated oil is placed in the container; s3, selecting a corresponding light source to irradiate the transformer deteriorated oil in the container according to the optimal process conditions so as to decompose colored substances in the transformer deteriorated oil, and recording the dielectric loss rate of the irradiated transformer deteriorated oil; and S4, adding an adsorbent into the container to further adsorb and decolorize the irradiated transformer deteriorated oil. According to the invention, the treatment is carried out under the optimal process condition, so that the dielectric loss reduction and decoloration treatment of the transformer deteriorated oil achieves better and more stable effects, the regeneration treatment cost is low, and meanwhile, no pollution is caused to the environment.

Description

technical field [0001] The invention belongs to the technical field of transformer degraded oil treatment, in particular to a treatment method for reducing dielectric loss and decolorization of transformer degraded oil. Background technique [0002] With the development of the power industry, the demand for power oil is increasing, and the power oil under certain operating conditions of temperature, atmosphere and electromagnetic field will inevitably deteriorate. Deteriorated power oil generally has a high active ingredient, and it is not economical to drain or downgrade it. The regeneration of degraded power oil is an effective saving measure that can generate significant economic benefits and protect the environment. [0003] At present, many domestic power generation units can only rely on mechanical filtration for the treatment of degraded transformer oil. Most of them use the traditional acid-alkali clay method for regeneration, which is labor-intensive and time-consu...

Problems solved by technology

[0003]At present, many power generation and power supply units in China can only rely on mechanical filtration for the treatment of transformer deteriorated oil, and most of them use the traditional acid-alkali clay method for regeneration. The method is labor-intensive and time-consuming, and pollutes the environment; in addition, the active ingredients in transformer degraded oil are generally high, and the regeneration treatment cost is high; and the selection of process conditions in the treatment process affects the best effect of dielectric loss reduction and decolorization of transformer degraded oil
