Investigation and Study on Wastage of Transformer Oil in the Process of Vacuum Purification

Release date:2018-02-26 15:00 source:http://www.hlamec.com clicks:

According to analysis of transformer oil cleavage in vacuum purifying by 8 sets vacuum oil purification machines,we studies factors of gases release in this process: transformer oil flowing electrification,energy radiation of bubble phase conversion and malfunction of oil purification machine.In accordance with the theoretic research,transformer oil flowing mode is improved under vacuum condition and applied to 136 sets vacuum oil purification machines.The results indicate that improvement can reduce transformer oil cleavage in vacuum purification.

 

Vacuum purification is one of the main methods for dehydrating and degassing on transformer oil.theory analysis of transformer oil wastage phenomenon under the condition of vacuum purification was carried out,and the simulated experiments were made in the laboratory under different temperature and vacuum degree,the comparative study was done by the industrial device at the same time.Experimental results show that the wastage of transformer oil increases with an increase in experimental temperature and a decrease in vacuum degree.The lower the temperature,the higher the vacuum degree,the less the wastage of transformer oil.The minimum wastage is 0.02%·h-1,the maximum wastage is 0.38%·h-1.The wastage of transformer oil is 0.04% ·h-1 under cooling filter condition(30℃)and the wastage of transformer oil is 0.08%·h-1 under heating filter condition(60℃)with industrial vacuum oil filter.
