Description

Technical Field

[0001] The present invention relates to the technical field of transformers, in particular to a marine waterproof transformer. Background Art

[0002] In the power system of a ship, transformers play a vital role. Since ships are in a humid marine environment with a lot of salt for a long time, this places extremely high demands on the waterproof and corrosion-resistant performance of the transformer. Some existing marine transformers achieve waterproofing by adopting a sealing structure. For example, sealants are used to seal the gaps in the transformer shell, or special sealing gaskets are used to effectively isolate the inside of the transformer from the external humid environment, thereby ensuring the waterproof effect to a certain extent. However, good sealing will make it difficult for the heat generated inside the transformer to dissipate. During the operation of the transformer, the internal windings and iron core will generate a lot of heat due to the passage of current and electromagnetic induction. If this heat cannot be dissipated in a timely and effective manner, it will seriously affect the service life and working stability of the transformer, and may even cause safety accidents.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] See also Figures 1 to 13The present invention provides a technical solution: a marine waterproof transformer, comprising a waterproof box 2, and further comprising: an internal flow device 6, arranged in the waterproof box 2, for accelerating the flow of air inside the waterproof box 2; a cold water cavity plate 8, arranged in the waterproof box 2, and a cavity heat sink 9 is connected to the cold water cavity plate 8; the internal flow device 6 includes an air delivery component and a rotating cold air component connected to the air delivery component, the rotating cold air component includes a middle tube 616 rotatably arranged in the cold water cavity plate 8 and a plurality of branch plates 617 axially distributed on the middle tube 616 and connected to the middle tube 616; a power component 7, arranged on the branch plate 7.

When the sliding plate 612 drives the piston slide When the piston slide 67 moves toward the side close to the air inlet elbow 62, the gas inside the air inlet chamber 65 enters the exhaust chamber 66 in one direction through the connecting short pipe 68.

The middle pipe 616 and the branch plate 617 are in the cold water in the cold water chamber plate 8, which can cool the gas in the middle pipe 616 and the branch plate 617. Under the continuous operation of the gas transmission component, the cooled gas can be discharged through the diverter plate 2 613. 19 and the exhaust connecting pipe 620 are finally ejected from the exhaust plate 621, which can cool the gas on one side of the waterproof box 2 and then eject it from the other side. At the same time, it also accelerates the flow of air in the waterproof box 2, making the temperature distribution inside the waterproof box 2 more uniform, further improving the heat dissipation efficiency, and the middle tube 616 and the branch plate 617 rotate at the same time inside the cold water cavity plate 8, which not only accelerates the cooling of the gas inside the middle tube 616 and the branch plate 617, but also accelerates the flow of cooling water in the cold water cavity plate 8 and the cavity heat sink 9, thereby improving the heat transfer efficiency of the cooling water and thus improving the overall cooling efficiency.

A worm 79 is fixedly mounted on the connecting rod 78, and a worm gear 710 is engaged with the worm 79. The worm gear 710 is fixedly mounted on the middle tube 616. When the connecting shift plate 72 drives the sliding plate 612 to move, the connecting shift plate 72 also drives the folded rack 73 to move back and forth. Since the folded rack 73 is engaged with the matching gear 74, the folded rack 73 drives the matching gear 74 to rotate. The matching gear 74 drives the bottom gear 76 to rotate through the connecting column 75. The bottom gear 76 drives the driving gear 77 to rotate. The driving gear 77 drives the connecting rod 78 and the worm 79 thereon to rotate. The worm 79 is engaged with the worm gear 710.

[0035] like Figures 6 to 12 As shown, the electric push rod 71 of the power component 7 drives the connecting moving plate 72 to move, thereby driving the gas inside the waterproof box 2 to enter the middle pipe 616 and the branch plate 617 through the diverter plate 1 613. The middle pipe 616 and the branch plate 617 are in the cold water in the cold water cavity plate 8 to cool the gas. The cooled gas passes through the diverter plate 2 619 and the exhaust connecting pipe 620 and is finally ejected from the exhaust plate 621. It can cool the gas on one side of the waterproof box 2 and then eject it from the other side. At the same time, it also speeds up the flow of air in the waterproof box 2, so that the inside of the waterproof box 2 is cooler. The internal temperature distribution is more uniform, which further improves the heat dissipation efficiency. Through the cooperation of the internal flow device 6 and the power component 7, when the power component 7 is working, the connecting shift plate 72 drives the folded rack 73 to move back and forth, thereby driving the middle tube 616 to rotate. The middle tube 616 and the branch plate 617 rotate inside the cold water cavity plate 8 at the same time, which not only accelerates the cooling of the gas inside the middle tube 616 and the branch plate 617, but also accelerates the flow of cooling water in the cold water cavity plate 8 and the cavity heat sink 9, thereby improving the heat transfer efficiency of the cooling water and thus improving the overall cooling efficiency.

At the same time, the flow of air in the waterproof box 2 is accelerated, so that the temperature distribution inside the waterproof box 2 is more uniform, and the heat dissipation efficiency is further improved.

When the piston slide 67 moves toward the connecting elbow 610, the gas inside the air intake chamber 65 enters the exhaust chamber 66 in one direction. When the air moves, negative pressure is formed in the air inlet cavity 65, and the gas inside the waterproof box 2 enters the air inlet cavity 65 through the air inlet plate 61 and the air inlet elbow 62.
