Insulating oil aging test device and test method

Abstract

The invention discloses an insulating oil aging test device and a test method. The device comprises a box body, wherein a test mechanism is mounted on an inner side wall of the box body, and a guide mechanism for guiding the insulating oil to circularly flow in the test mechanism is mounted on the test mechanism. According to the device, a fog liquid bag and an electric push rod are arranged, operation of simultaneously injecting liquid with different contents into a plurality of oil storage chambers is realized, during injection, injected liquid can be fully mixed with oil liquid through theguide mechanism, a plurality of oil storage chambers are arranged, so high temperature applied to the insulating oil in the transformer and aging comparison tests of liquids with different contents can be simulated, multi-region quantitative oil aging detection can be automatically carried out in the same time period in the test process, quantitative insulating oil liquid containing different contents of liquid is automatically and simultaneously taken out from a plurality of oil storage chambers in each time period, soinsulating oil aging test detection can be carried out on the transformer in each time period in different states in a targeted manner, and the test result is 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
