The structure principle of transformer hygroscopic device

The hygroscopic is mainly to prevent the transformer oil to receive moisture erosion to reduce its power resistance, the main role of the hygroscopic is to absorb the moist moisture in the air.

The main composition of the hygroscopic is a connected iron tube and a glass container, and some desiccants are filled. In order not to cause the oil to leak, the overner tube of the hygroscope directly extends to the top space of the oil storage cabinet, and its tube is opposite to the expansion of the oil storage cabinet, which is likely to be relatively high. Oil surface.
