Insulation oleic acid value determination solution
The Acid value of transformer insulating oil is the total value of the acid in the oil, that is, the organic acid and the inorganic acid, generally in order to neutralize the acid in the LG insulating oil required potassium hydroxide Mg number to represent.
For the unused new transformer oil contains almost no acid, its acid value is quite small, but the oil in the long-term storage, especially into the electrical equipment into operation, will inevitably contact with oxygen in the air, oil is easy to be aging.
At the initial stage of oxidation, low molecular organic acids are mainly generated, and further oxidation produces high molecular organic acids and acid products. After the existence of all kinds of acid substances in the insulating oil, the electrical conductivity of the oil will be improved, the insulation of the oil will be reduced, and the corrosion of metals may also be generated.
In the case of high operating temperature (above 80 ℃), the aging phenomenon of solid fiber paper insulation material is promoted, thus shortening the service life of the equipment.
The oil acid value of the unused transformer is generally 0.03mgKOH/g, and the control acid value of the running oil is not greater than 0.1mgKOH/g.
Transformer oil insulation oil acid value detection method is in accordance with the GB/T264 standard detection, Shandong Shengtai instrument SH108 automatic acid value meter is designed in accordance with this method, automatic transformer oil acid value meter SH108 is the use of color touch screen operation, reagent is fully equipped, put the sample can be tested,
Can automatically measure the results, automatic printing, improve work efficiency, the use of this instrument can better detect the acid value of transformer oil.
SH108 automatic oleic acid level meter complies with the requirements stipulated in the People's Republic of China standard GB/T 264 "Determination of the acid value of petroleum products" and GB7599, GB7299.
The instrument adopts blue LCD large screen display, Chinese menu, no marker button.
Microcomputer automatic measurement, automatic printing, the test process to achieve computer automation
It can meet the needs of oil refineries, power plants and scientific research units, and is one of the essential instruments for oil analysis and quality inspection.
