A nitrogen compensation oil-immersed transformer of the present invention comprises a transformer oil tank, a nitrogen pipeline, an automatic nitrogen supplementing assembly, a nitrogen cylinder and apressure relief assembly, a pipeline valve is arranged at the top of the transformer oil tank, and one end of the nitrogen pipeline is connected with the pipeline valve. The automatic nitrogen supplementing assembly is connected with the other end of the nitrogen pipeline, the nitrogen cylinder is connected with the automatic nitrogen supplementing assembly, and the pressure relief assembly and the nitrogen pipeline are connected with the nitrogen compensation oil-immersed transformer. According to the present invention, the automatic nitrogen supplementing assembly is arranged between the nitrogen pipeline and the nitrogen cylinder, the automatic nitrogen supplementing assembly can control nitrogen in the nitrogen cylinder to enter the transformer oil tank through the nitrogen pipeline according to the rising and falling of the temperature of the transformer oil in the transformer oil tank, and the expansion and contraction of the transformer oil are controlled, so that the situations that an existing oil-immersed transformer is damaged and cracked due to the aging of an oil conservator capsule, an abnormal alarm is given for the oil level of an oil level indicator and the like,can be avoided, and the economic losses caused by maintenance of the oil conservator capsule are greatly reduced.
Description
technical field [0001] The application relates to an oil-immersed transformer, in particular to a nitrogen-compensated oil-immersed transformer. Background technique [0002] Conventional capsule oil-immersed transformers are commonly used in the existing transformer industry. As the temperature of the oil inside the transformer rises and falls, the expansion and contraction of the transformer oil is realized by connecting the gas pipe to the capsule oil conservator. It communicates with the atmosphere to achieve expansion and contraction. [0003] In the process of realizing this application, the inventor found that during the operation of the existing capsule oil-immersed transformer, the oil conservator capsule was damaged and cracked due to the aging of its own material, nitrile rubber, resulting in abnormal oil level alarm on the oil level gauge, etc. Happening. SUMMARY OF THE INVENTION [0004] The embodiment of the present application provides a nitrogen-compensat...
