Research and Technology on On-line Monitoring the Oil Level of Non contact Transform Oil Conservator

Operation statistics and a large number of site cases proved that damage to the oil conservator rubber had no direct connection with operation periods. However, with the increasing service life of oil conservator, the probability of hidden dangers will continue to increase. The traditional oil level reading could only rely on manual checking and inspection, and its reliability was difficult to guarantee. This paper introduced the research and technology on on-line monitoring the oil level of non contact transform oil conservator, which can quickly and accurately measure the oil level inside the transform’s oil conservator without opening the oil conservator when the transform is not in operation. It can shorten the time of fault assessment and diagnosis effectively, improve the efficiency of maintenance, and thus improve the economic effect.
