Humidity monitoring device for transformer silica gel respirator

The invention provides a humidity monitoring device for a transformer silica gel respirator, which comprises an upper flange, a communicating pipeline, a lower flange and a sensing unit, the communicating pipeline is connected with the upper flange and the lower flange, the sensing unit is arranged on one side of the communicating pipeline, the communicating pipeline and the sensing unit are detachably fixed, and the communicating pipeline is integrally formed; the upper flange is connected with an oil conservator capsule pipeline, and the lower flange is connected with the silica gel respirator; and the sensing unit is used for monitoring the change of humidity in the transformer in real time. Whether silica gel or oil needs to be replaced by the silica gel respirator or not is determined through the humidity value, and whether the silica gel respirator has defects or not can be visually reflected; an existing respirator does not need to be dismantled, and the economic cost is effectively saved. 本发明提供一种用于变压器
