Description

Technical Field

[0001] This utility model relates to the field of oil storage tank technology, specifically a stable internal oil capsule oil storage tank. Background Technology

[0002] The oil conservator is a crucial component of an oil-immersed transformer, located at the top of the transformer tank. Its main functions include compensating for volume changes in the transformer oil due to temperature variations, ensuring the tank remains consistently full of oil, and minimizing the contact area between the oil and air to prevent moisture absorption and oxidation of the insulating oil, thereby extending the transformer's service life. A bladder-type oil conservator is based on an open-type oil conservator, with an internal fabric-reinforced rubber bladder for air isolation. This bladder forms a sealed structure with the outer shell. The bladder expands and contracts to compensate for the volume of the insulating oil, and the bladder's interior is open to the atmosphere via a breather.

[0003] Currently, in internal oil-filled capsule oil tanks, the capsules on both sides are typically connected directly to the fixing rings on the inner wall of the tank via hooks. This structure makes the hooks prone to being pulled hard during volume compensation, potentially causing them to break. Furthermore, during oil compensation, the capsule expands or contracts, causing the connection between the bottom of the capsule and the main connecting pipe to wobble, which could also lead to breakage at the connection point. Therefore, an improved technology is urgently needed to address this problem in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a stable internal oil capsule storage tank to solve the problems mentioned in the background art.
