Description
Technical field
The utility model relates to transformer oil, and the treatment system of the transformer oil especially exceeding standard with dielectric loss is relevant.
Background technology
Transformer oil dielectric loss factor (hereinafter to be referred as dielectric loss) can reflect the quality of transformer oil insulation characterisitic, and the degree of aging of reflection transformer oil under the effects such as electric field, oxidation and high temperature, reflects the degree that oily Semi-polarity impurity and charged colloidal particle etc. pollute.In actual use, we find that reason that transformer oil dielectric loss exceeds standard is except transformer self internal contamination, also may comprise the pollution from external contamination thing that transformer oil is suffered, pollutant all has a significant impact the generation of transformer oil dielectric loss value as pollutants such as acidic oxidation products, a small amount of microbe, metal oxide, colloid indissoluble things.The transformer oil that transformer uses is generally all by carrying oil line pipe to be transported in transformer from absolute oil tank, after arriving transformer through conveyance conduit, detect and find that the situation that raises or exceed standard appears in the relative absolute oil tank of dielectric loss value, be due to the pipeline oil system of carrying transformer oil contaminated thing pollute.
At present, solving oil pipeline pollution problem produces the super calibration method of oily dielectric loss and normally rinses oil pipeline and change oil.While adopting the method for rinsing oil pipeline, even if repeatedly strong flushing oil pipeline, after oil-piping commencement of commercial operation, detects transformer oil dielectric loss value by sampling at pipeline oil-out, discovery is along with extend running time, and transformer oil dielectric loss or rising are until surpass acceptance value.The way that employing is changed oil: change underproof transformer oil, conventionally need the old oil in emptying oil-piping, then with qualified transformer oil, whole pipeline is rinsed, finally inject new qualified transformer oil.But simply change oil, can not " rinse " thoroughly, after changing oil, there will be transformer oil dielectric loss to raise gradually and even surpass the situation of acceptance value.In addition, the expense of changing oil is large, is unfavorable for energy-conservation and environmental protection.
For transformer oil in oil pipeline, produce the problem that dielectric loss raises, we draw to draw a conclusion after to oil pipeline analysis: 1, duct cleaning is not in place, as having water after pickling, do not rinse well, or coat transformer oil (before two pipeline butt welding) after not drying up in time after rinsing, cause burning deposits yields.2, during pipeline welding butt welding, otch out-of-flatness or there is no chamfering,, there is pit or recessed joint in its pipe interior weld seam out-of-flatness of postwelding, pollutes the hiding-place of thing.3, pipeline rout or theoretical caliber are unreasonable, in transformer oil flow process, because design, unreasonablely cannot take away pollutant (as too high in pipeline climb altitude), or the excessive flow velocity that causes of the caliber of pipeline is excessively slow, cause oil stream to wash away dynamics to inside pipe wall inadequate, the pollutant (as acidic oxidation products, a small amount of microbe, metal oxide, colloid indissoluble thing etc.) that causes oily dielectric loss value to raise is remained in pipe.Therefore how effectively solving oil pipeline and pollute, is industry urgent problem thereby transformer oil is transported to safely and reliably in transformer from oil tank.
