Description

Technical Field

[0001] The present application relates to the technical field of oil injection components, and in particular to an oil injection component for a transformer. Background Art

[0002] In the prior art, when the transformer is performing the oil filling operation of insulating oil, new insulating oil needs to be poured along the oil filling port. In order to prevent the insulating oil from spilling, a funnel is usually used to divert the insulating oil. However, the existing funnel does not have a vent, so when the poured insulating oil fills the channel of the funnel, it is easy to form a liquid seal and cause stagnation of the insulating oil. Therefore, the user needs to control the filling of the insulating oil at all times to avoid the formation of a liquid seal. When the liquid seal is formed, the funnel needs to be manually pulled out and inserted so that the insulating oil inside the funnel is quickly discharged. Although the waste of spilling the insulating oil is reduced, the filling time of the insulating oil is greatly increased. As the filling time of the insulating oil is prolonged, the social cost caused by the transformer shutdown is also greatly increased. Utility Model Content

[0003] The problem to be solved by the present application is that when the existing transformer uses a funnel for oil filling operation, a liquid seal is easily formed, which causes stagnation of the insulating oil. Although the insulating oil can reduce the filling loss, the filling time is greatly increased.

[0004] In order to solve the above technical problems, the present application provides an oil filling assembly for a transformer, including an integrally formed funnel body, the funnel body being divided into an oil hopper part and an air hopper part which are detachable up and down and arranged in a socket manner, the oil hopper part being used for filling insulating oil, and the air hopper part being used for exhausting air inside the transformer when filling insulating oil.

[0005] Since the oil filling assembly of the present application is designed with an oil hopper part and an air hopper part, the insulating oil can be injected through the oil hopper part, and the air can be discharged during oil filling through the air hopper part, thereby solving the problem that when the transformer of the prior art uses a funnel for oil replenishment, a liquid seal is easily formed, which causes stagnation of the insulating oil, resulting in a significant increase in the filling time although the filling loss of the insulating oil can be reduced.

[0011] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0012] The present application relates to an oil injection assembly for a transformer, such as Figure 1-4 As shown, the oil filling assembly includes an integrally formed funnel body. There are two funnel bodies, which are arranged in an upper and lower detachable socket manner. The funnel body is divided into an oil funnel part 1 and an air funnel part 2 according to different functions. The oil funnel part 1 is used for filling the insulating oil, and the air funnel part 2 is used for exhausting the air inside the transformer when the insulating oil is filled. Therefore, by means of the combined operation of the oil funnel part 1 and the air funnel part 2, liquid sealing can be avoided when the insulating oil is filled, so that the insulating oil can be stably and smoothly filled into the transformer.

[0013] The oil sump member 1 comprises an oil sump body 3 and an oil plug 4. The oil sump body 3 is arranged at the upper part of the oil sump member 1, and the oil plug 4 is arranged directly below the oil sump body 3. In order to further increase the flow rate of the insulating oil, a spirally arranged guide bar 5 is added inside the oil plug 4. The number of the guide bars 5 can be one or more. In order not to occupy too much volume inside the oil plug 4, the number of the guide bars 5 is preferably three.

[0014] The gas bucket member 2 includes a gas bucket body 6 and an air plug 8. The gas bucket body 6 is arranged at the upper part of the gas bucket member 2, and the air plug 8 is arranged directly below the gas bucket body 6. In order to facilitate the air inside the transformer to flow out along the gas bucket member 2, a cavity for air flow is formed between the gas bucket body 6 and the oil bucket body 3, the air plug 8 and the oil plug 4. At the same time, in order to ensure the stability of the cavity, the top of the oil bucket body 3 overlaps the gas bucket body 6, and the bottom outer wall of the oil plug 4 abuts against the bottom inner wall of the air plug 8.

[0015] In order to realize the flow operation of the air inside the transformer, air outlet holes 7 are opened on the side wall of the gas bucket body 6, and the air outlet holes 7 are evenly arranged along the circumferential direction of the side wall, and air inlet holes 9 are opened on the side wall of the air cannula 8, and the air inlet holes 9 are evenly arranged along the circumferential direction of the side wall, so that the air inside the transformer can enter along the air inlet holes 9 and then be discharged through the air outlet holes 7.

[0016] When in use, firstly, the oil bucket member 1 and the gas bucket member 2 are socketed, and then the insert tube of the gas bucket member 2 is inserted into the oil filling port of the transformer, and then the insulating oil is poured along the oil bucket body 3 of the oil bucket member 1, and then the insulating oil will flow into the transformer along the oil bucket body 3 and the oil insert tube 4, and the air inside the transformer will enter the cavity along the air inlet hole 9 of the air insert tube 8, and then be discharged along the air outlet hole 7, thereby realizing the separate flow operation of the insulating oil and the air, avoiding the liquid seal when filling the insulating oil, and ensuring that the insulating oil can be filled stably and quickly.

[0017] It is to be understood that the present application is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present application. In addition, under the guidance of the present application, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present application. Therefore, the present application is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are within the scope protected by the present application.
