摘要
介绍一种快速、准确地测定运行中变压器油酸值的新方法。阐述该方法的试验原理、方法和计算 ,并提供该方法与GB 75 99— 1987所采用方法的对比试验数据。数理统计结果表明 ,两种方法在试验结果上无显著性差异。新方法具有快速、简便、易操作的特点 ,有利于在实验室应用。
A new method of rapid measurement on the acid number in transformer oils in service is described with its test principle,experimental procedures,computation and comparative test data of the new and conventional method(GB7599-1987). Mathematical statistics show that there are no obvious differences between the two methods in test results. The timesaving and easy-to-operate advantages of the new method enable it to spread easily in laboratory.
