Problems solved by technology

However, it takes more than ten or even dozens of hours to separate, and the separation is not very complete
In addition, after the polymer breathable membrane is soaked in transformer oil for a long time, it will cause the deformation and deterioration of the membrane, which requires the staff to replace the polymer membrane after a period of time
[0005] (2) The oil-gas separation device based on the principle of vacuuming uses a small motor to drive the bellows to compress repeatedly, and vacuumizes repeatedly to extract the dissolved gas in the oil, and the waste oil is still returned to the

Abstract

The invention relates to an on-line monitoring oil-gas separation device for a transformer, and belongs to the technical field of power engineering. The device comprises an oil-gas separation chamber, a vacuum pump, an ultrasonic vibrator, a scavenge oil pump, a PLC control module, an electromagnetic valve, a liquid level detector, an oil-gas filter, a throttle valve and a connecting pipe. All electric parts are controlled by the PLC module to cooperate with each other to work in real time. The device utilizes a method of combining the vacuum pumping and the sonic oscillation principle for the oil-gas separation, so that the degassing efficiency is higher and the degassing process is faster; and moreover, the device also has the advantages of high automaticity, small volume and convenient arrangement, and is quite suitable for detecting faults based on dissolved gas in the oil of oil immersed type equipment such as a transformer and the like.

Description

technical field [0001] The invention relates to an oil-gas separation device in the technical field of electric power engineering, in particular to a transformer online monitoring oil-gas separation device based on the principle of ultrasonic oscillation. Background technique [0002] With the rapid development of power grid construction, the society has put forward higher requirements for the safety and stability of the power grid. The failure of electrical equipment, especially the failure of power transformers, has always been the main factor that endangers the stable and safe operation of the power grid. Therefore, real-time online monitoring of the operating status of power transformers is particularly important, which is directly related to the stable and reliable operation of the power grid. Rapidly separate out in real time. [0003] After searching the literature of the prior art, it was found that the book "On-line Monitoring and Fault Diagnosis of Gas in Oil of ...
