Abstract

The invention provides a vacuum oil filtering method of natural ester insulating oil for a transformer, belonging to the technical field of transformer manufacturing processes. The method comprises the following steps that: a first container and a second container are arranged, and realizes mutual communication through gas pipes; an oil filtering mechanism for heating and filtering the natural ester insulating oil is arranged; a nitrogen mechanism for filling nitrogen into the gas pipes and discharging nitrogen is arranged; the pressure of nitrogen in the first container and the second container is kept stable; and the oil filtering mechanism and the nitrogen mechanism are started so as to allow the natural ester insulating oil in the first container or the second container to flow to theoil filtering mechanism and the temperature of the natural ester insulating oil to meet oil filtering requirements. The vacuum oil filtering method of the natural ester insulating oil for the transformer, provided by the invention, has the technical effects of high heating temperature and difficult oxygenolysis of the natural ester insulating oil, oxygen isolation and high oil filtering efficiency.

Description

technical field [0001] The invention belongs to the technical field of transformer manufacturing technology, and more specifically relates to a method for vacuum filtering natural ester insulating oil used in transformers. Background technique [0002] Most transformers use mineral oil for cooling, and most of them are hydrocarbon mineral oils, which are easy to cause environmental pollution. Although lipid vegetable oil suitable as transformer cooling fluid is not widely used, lipid vegetable oil is renewable, non-toxic, easy to decompose, and has an explosion point The high characteristics make it more and more widely used. Regardless of hydrocarbon mineral oil or fatty vegetable oil, it is generally necessary to filter to the standard required by the transformer before use, and when the transformer fails, it is usually necessary to filter the internal transformer oil to the required standard. [0003] The oil filtration process of traditional transformer hydrocarbon mine...
