To know this problem, we should first understand what the role of the transformer oleic acid value tester is. Transformer oleic acid value tester is an instrument for the conventional testing items of oil-filled electrical equipment used in the power system or industrial and mining enterprises. The main oil-filled electrical equipment includes transformers, steam turbines, etc., which use oil-filled electrical equipment to achieve the effect of insulation. So why use transformer oleic acid value tester to do such a detection?
This is because with the development of the national power industry, high parameter, large capacity generator set is also expanding the scope of use, the national relevant provisions of the electric power oil supervision, management is more and more strict. The oleic acid value of insulating oil in electrical equipment is one of the most important criteria to judge the quality of oil. Common insulation oil are: transformer oil, turbine oil and digital control system used by the phosphate ester, hydraulic oil. The increase of oleic acid value of electrical equipment in operation, in the transformer, will increase the electrical conductivity of the transformer, and affect the insulation performance of the oil. If the operating temperature is relatively high, it will also lead to the aging of solid fiber insulation materials, especially when the low molecular acid content becomes high, and the oil contains water, which will reduce the insulation level of electrical equipment and shorten the service life of the equipment. The phenomenon of rising oleic acid value in steam turbine not only indicates the aging of insulating oil, but also the chemical substances in oil will lead to emulsification of oil, thus affecting the lubrication effect of oil, resulting in friction and heating of parts, affecting the safe operation of equipment. If the acid value of fuel resistance increases, the volume resistivity of fuel resistance will be reduced, which will cause the corrosion of the servo valve and threaten the safe operation of the whole unit. Oleic acid levels should increase over time, and it is not normal for oleic acid levels to decrease. To find out the reason, in order to improve the accuracy of the test results, to provide guarantee for the safe operation of the equipment.
This is why we use transformer oleic acid value tester to determine the oleic acid value of oil products. The transformer oleic acid value tester uses the chemical analysis of acid-base neutralization reaction as its basic frame by automatic digital microcomputer control technology. In addition, it is equipped with self-developed titration end point logical judgment and background blank deduction judgment procedure, which enables the instrument to quickly measure the oleic acid value of transformer and turbine, and the measurement results have high accuracy and precision. Automatic instrument completely replace manual operation, not only reduce the labor intensity of the test personnel, but also improve the work efficiency, more importantly, reduce the harm of organic solvents and other chemicals to the human body.
