Benefits of technology

Inventions described by this inventor involve changing how much oil flows from one side into another without stopping or requiring filters that can get dirty quickly due to their repeated use over time. These improvements make it more efficient than traditional methods like turning off an engine when there're no longer needed. Additionally, they don’t require expensive equipment such as pumps or other components at every stage, making them cost-effective compared with older systems.

Problems solved by technology

There are technical problem addressed in this patented text that requires an improved way to complete transformer lubricating oil filtraction while avoiding having to stop or disconnect from other parts of the system altogether.

Abstract

The invention relates to a filtering method for transformer oil. The filtering method comprises the following steps of: firstly, sequentially connecting two ends of each of a first valve, a fourth valve, a second valve and a third value by pipelines to form a valve bank which is in an annular structure and respectively connecting a transformer oil tank, an oil return port of an oil filter, a first oil tank and an oil outlet of the oil filter; secondly, starting the oil filter for filtering oil in the transformer oil tank; and thirdly, pumping the filtered oil into the transformer oil tank. The filtering method has the beneficial effects that: firstly, the filtering method is simple in operation; and the oil filter is not needed to be closed in the filtering process, so that the work period is shortened and the efficiency is improved; secondly, devices adopted in the method are conventional devices, are low in price and are convenient for popularization and application; thirdly, the missing of oil products and the pollution to the environment are avoided; and fourthly, the filtering method is not only suitable for oil filtering occasions, but also is suitable for oil exchange and new oil injection occasions.
