APPARATUS AND METHOD OF DEHYDRATION OF TRANSFORMER INSULATING OIL BY CONTINUOUS FLUID FLOW

摘要

The invention deals with increasing the quality of insulating mineral oil in transformers, by providing an isolating layer of flowing nitrogen over the oil's surface to keep ambient air from combining or absorbing with or in the oil, also removes water from the oil. The invention has application in the field of transformers where it is useful to provide self-sufficient and environmentally friendly equipment and methods to prolong service life and reliability between service or inspection of medium, high, and extra-high voltage power. A method and apparatus is provided which by continuously flowing a fluid, preferably gaseous nitrogen, across the surface of insulating oil in an electrical transformer both segregates the oil from atmospheric oxygen and picks up and removes water (among other things) from the oil. This reduces dangerous and harmful water buildup in the transformer on a continuous basis.
