Problems solved by technology

However, the problem with this method of carbon dioxide elution is that CO 2 The flow rate is not easy to control precisely, and the potassium hydroxide solution is 2 The absorption efficiency and the determination of the blank value need to be carefully studied. More importantly, this method is only suitable for the determination of the gas content of new oil. 2 The gas cannot be detected, making the measurement result low
In order to improve the degassing efficiency of oil with low gas content, it is generally used to increase the vacuum volume, that is, to increase the volume of the degassing container. Although the degassing efficiency is improved, the concentration of gas components in the gas phase is reduced, and the corresponding vacuum The differential pressure change of the gauge is reduced, which has higher requirements for the precision of the device

Abstract

The invention discloses a transformer oil gas content testing device and a transformer oil gas content testing method for measuring density through a U-shaped oscillation tube, belongs to the technical field of electric power system detection, and solves the problem of how to calculate the gas content in oil according to the change of the density of a tested oil sample before and after vacuum degassing so as to improve the testing precision. According to the device, the U-shaped oscillation tube is used for measuring the density of the oil sample, the measuring precision is very high, the requirement for accurate measurement of the density change of the oil sample before and after degassing can be met, and the gas content in the oil is calculated according to the density change of the oil sample before and after vacuum degassing of the measured oil sample for the first time. The method is a test method with a brand new test principle, is simple to operate, facilitates field test and can adapt to measurement of oil samples with different gas contents.

Description

technical field [0001] The invention belongs to the technical field of electric power system detection, and relates to a transformer oil gas content testing device and method for measuring density with a U-shaped oscillating tube. Background technique [0002] The carbon dioxide elution method is to use the supersaturation of carbon dioxide to replace and carry out the dissolved gas in the oil, and then pass through the absorption tube equipped with potassium hydroxide solution at the same time, so that the carbon dioxide is completely absorbed by the lye, so that all the dissolved gas in the oil enters the gas measuring tube , based on which the content of dissolved gas in the oil is determined. However, the problem with this method of carbon dioxide elution is that CO 2 The flow rate is not easy to control precisely, and the potassium hydroxide solution is 2 The absorption efficiency and the determination of the blank value need to be carefully studied. More importantly,...
