A kind of insulating oil aging test device and test method

Abstract

The invention discloses an insulating oil aging test device and a test method, which include a box body, a test mechanism is installed on the inner wall of the box body, and a guide for guiding the circulating flow of insulating oil in the test mechanism is installed on the test mechanism. Mechanism, the present invention can realize the operation of injecting different contents of liquid into multiple oil storage chambers at the same time through the mist liquid bag and electric push rod, and can fully mix the injected liquid with the oil through the guiding mechanism during injection, and more The setting of two oil storage chambers can simulate the aging comparison test of applying high temperature and different contents of liquid to the insulating oil in the transformer, and can automatically perform multi-region quantitative oil aging detection in the same period of time during the test, that is, Automatically take out a certain amount of insulating oil containing different contents of liquid from multiple oil storage chambers at the same time at each time period, so that the insulation oil aging test can be carried out for each time period under different conditions in the transformer, so that The test results are more reliable.

Description

technical field [0001] The invention relates to the field of insulating oil testing, in particular to an insulating oil aging testing device and testing method. Background technique [0002] Power equipment mainly includes power generation equipment and power supply equipment. Power generation equipment mainly includes power station boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Among them, transformers are more common in daily life, and insulating oil is often used in transformers. [0003] During the long-term use, the insulating oil in the transformer is prone to aging, and the main reasons for the aging of the insulating oil are temperature and humidity (that is, a small amount of water has penetrated into the insulating oil), etc. At this time, the staff will pass the insulating oil aging Experiments are used to study the aging law of insulating oil. At present, there are mainly the following methods for the aging test of insulatin...

Problems solved by technology

[0005] The object of the present invention is to provide a kind of insulating oil aging test device and test method, to solve the aging test of adding trace water into the oil liquid at a higher temperature in the prior art, just need to control the water during the test process. The amount of addition is adjusted. If a large amount of water is directly injected, the experiment will lack comparative data and the reliability of the final data will not be high. It is incompatible with water, and if it is added improperly, it will easily cause technical problems that water will accumulate together
