Problems solved by technology
[0004] 1. The cleanliness and dryness of the collection container or oil tank and the pipeline for the discharged insulating oil are very high. Once it is not dust-free and dry, the deterioration of the insulating oil will be accelerated, and the insulation of the transformer will be affected if it is serious;
[0005] 2. The oil is discharged through the special oil discharge valve at the bottom of the transformer, and the oil discharge volume cannot be accurately grasped, and it is easy to discharge excessive insulating oil, which increases the workload of oil injection;
[0006] 3. The above-mentioned oil discharge and oil injection operations are cumbersome, and there are problems such as waste and loss of insulating oil during the operation process

The invention provides a method for high-efficiently carrying out oil draining and oiling during replacement of an oil-immersed transformer pipeline accessory. Exhaust valves of a cooling oil pump anda cooler system are used to drain oil from an oil-immersed transformer and accurate oil draining is achieved. A remaining oil storage space of an oil conservator is used to store discharged insulating oil so as to avoid problems of pollution of insulating oil and the like caused by external connection of an oil storage tank. Wastes of insulating oil during a work process are maximumly reduced andoil draining and oiling efficiency is greatly increased.
Description
technical field [0001] The invention relates to a method for quickly draining and filling oil when replacing pipeline accessories of an oil-immersed transformer, and belongs to the technical field of power generation and distribution systems. Background technique [0002] Oil-immersed transformers are widely used in all aspects of power generation and distribution in power systems, and are important power distribution equipment in power systems. With the increase of the service life, oil-immersed transformers are likely to have many common problems such as air leakage from the cooling oil pump, oil leakage from poorly sealed auxiliary valves, and water leakage from the external cooler. Once the above situation occurs, and the nearest valve cannot form an effective isolation, only by draining the insulating oil of the transformer can the accessories of the pipeline be replaced. The traditional oil discharge method for oil-immersed transformers below 220kV is to discharge the...
