Description

technical field

[0001] The invention relates to the field of oil-immersed transformers, more precisely, it relates to a double-tube moisture absorber for oil-immersed transformers. Background technique

[0002] The moisture absorber in the oil-immersed transformer is a device that prevents moisture and dust in the air from entering the transformer oil. However, the filter in the dehumidifier is often blocked by dust; and usually a reusable desiccant is placed in the dehumidifier. When the desiccant absorbs enough moisture to fail, the desiccant can be reheated to reabsorb moisture. capacity; but in the dehumidifier in the prior art, the hygroscopic agent can only be taken out and reheated, and then filled with a new hygroscopic agent. serious. Contents of the invention

[0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a kind of airflow passing through the annular filter screen from bottom to top, and the dust...

Embodiment Construction

[0013] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0014] The advantages of the double-tube moisture absorber for oil-immersed transformers of the present invention are: the airflow passes through the annular filter screen from bottom to top, and the dust is not easy to adhere to the filter screen; Clean up the dust; there is a screw plug on the head, and the rod-shaped heater can be inserted into the inner cylinder through the screw plug hole, so as to heat the desiccant and avoid taking out and putting in the desiccant.

[0015] Such as figure 1 , figure 2 As shown, a double-tube moisture absorber for oil-immersed transformers includes an outer cylinder 1, an air inlet pipe 2 and an air outle...
