Transformer with breathing monitoring control function

Abstract

The invention provides a transformer with a breathing monitoring control function. A main gas circuit is mounted on a breathing apparatus, and a drying cavity and an air control valve are arranged onthe main air path. When the transformer is heated to expand, redundant air in an oil conservator is exhaled through the main air path, and when the oil temperature of the transformer is reduced, air is sucked in through the main air channel, and the sucked air passes through the drying cavity to be dried and then enters the transformer. A processor is connected with a transformer oil temperature detection module to obtain the oil temperature information of the transformer in an operation state and store the oil temperature information in a memory, meanwhile, when the monitored oil temperatureexceeds a preset threshold value, a valve control circuit is connected with the air control valve to control the air control valve to be opened, so that the transformer exchanges air. According to theinvention, the problem that the breathing state of the transformer cannot be effectively monitored is solved, the breathing state of the transformer is monitored, and alarm processing is carried outwhen abnormal breathing, abnormal oil level and other conditions are judged.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer with a breathing monitoring and control function. Background technique [0002] The transformer respirator is mainly used to dry and filter the air inhaled by the transformer. During the breathing process, more water will be produced. At the same time, after the rainy season, the respirator retains more water. When winter comes, the respirator will be blocked, causing difficulty in breathing for the transformer. A large pressure is generated, and when the temperature reaches a certain level, the respirator blocks the ice crystal and melts, and the internal pressure of the transformer is released instantaneously, causing heavy gas action and tripping. Contents of the invention [0003] In order to overcome the deficiencies in the above-mentioned prior art, the present invention provides a transformer with respiratory monitoring and control function, including:...
