Technical Field

[0001] This utility model relates to the field of packaging structure technology, and specifically to a moisture-proof packaging structure for natural ester insulating oil. Background Technology

[0002] Natural ester insulating oil is an insulating oil extracted from plant seeds, mainly used for insulation and cooling of transformers or similar electrical equipment. It possesses properties such as environmental friendliness, fire resistance, and high-temperature resistance, and is gradually becoming a substitute for traditional mineral insulating oils.

[0003] Because natural ester insulating oil is hydrophilic, it is very easy for air to enter during the handling process. The introduction of moisture from the air will cause the internal water content of the natural ester insulating oil to increase, which will affect the normal use of the natural ester insulating oil and cause great inconvenience.

[0004] To address the aforementioned issues, this application proposes a moisture-proof packaging structure for natural ester insulating oil. Utility Model Content

A first rectangular block is fixedly connected to one side of the liquid extraction tube, and a second screw hole is provided on one side of the first rectangular block. A first threaded clamp is threadedly connected to the inner wall of the first screw hole and the second screw hole.

[0012] By setting a first threaded clamp, the cover plate and the liquid extraction tube can be fixed together with the first and second threaded holes.

[0013] Preferably, the top of the placement ring frame is snapped with a first annular plate and a second annular plate, and the top of the first annular plate and the second annular plate are fixedly connected with auxiliary covers.

[0017] The beneficial effects of this utility model are:

[0018] With the auxiliary oil extraction structure, the piston rod can move up and down under the action of the threaded rod, allowing the natural ester insulating oil to be extracted through the liquid extraction hole inside the piston rod. Throughout the process, the inside of the packaging can remains isolated from the outside, thus preventing moisture from the outside air from affecting the natural ester insulating oil inside. Furthermore, the cover plate can be removed for easy addition of natural ester insulating oil.

[0019] By incorporating an auxiliary dehumidification structure, absorbent materials such as activated carbon can be placed in the placement ring to absorb moisture. During the return process from the liquid dispensing hole to the packaging can, it can linger at the placement ring for a period of time, allowing the activated carbon inside the filter holes to absorb moisture, thus preventing moisture from the air inside the dispensing hole from entering the packaging can.
