[0002] Oil-immersed transformer is a common power equipment, which uses oil as an insulating medium to protect the internal components of the transformer. Long-life oil-immersed transformers usually use high-quality insulating oil and high-quality insulating materials to ensure that they can maintain stable performance in long-term operation. Long-life oil-immersed transformers have high-quality insulating materials and oils, good heat dissipation performance, and high-quality manufacturing processes. They can maintain stable performance in long-term operation and are one of the common important equipment in power systems.
[0003] In the prior art, an oil-immersed transformer is often provided with a container filled with insulating oil, and such container is usually directly arranged inside or on the surface of the transformer. However, insulating oil is usually a substance with a high fire hazard.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] Reference Figure 1-4, an embodiment provided by the utility model: a long-life oil-immersed transformer, comprising a transformer body 1, a first connecting pipe 2 is fixedly arranged on one side of the upper end of the transformer body 1, a connecting mechanism 3 is fixedly arranged on the other end of the first connecting pipe 2, a second connecting pipe 6 is fixedly arranged on the other end of the connecting mechanism 3, a storage tank 4 is fixedly arranged on the other end of the second connecting pipe 6, the transformer body 1 is connected with the second connecting pipe 6 and the storage tank 4 through the first connecting pipe 2, which facilitates the insulating oil inside the storage tank 4 to flow into the inside of the transformer body 1, and realizes the use of oil as an insulating medium to protect the internal components of the transformer, so that it can maintain stable performance in long-term operation and improve the service life, a safety mechanism 5 is fixedly arranged on one side of the connecting mechanism 3 near the upper end, the connecting mechanism 3 includes a first connector 301 and a second connector 308, and the control of the circulation of the insulating oil is realized by the clutch of the first connector 301 and the second connector 308;
[0030] The safety mechanism 5 includes a support rail 504, and two movable slide grooves 502 are provided inside the upper end of the support rail 504. The upper ends of the two movable slide grooves 502 are both slidably provided with a stabilizing frame 501, so that the stabilizing frame 501 can drive the storage tank 4 to move horizontally. A detection belt 506 is fixedly connected between one side of the two stabilizing frames 501 and the two movable slide grooves 502. The melting point of the detection belt 506 is relatively low. A tension spring 503 is fixedly connected between the other side of the two stabilizing frames 501 and the two movable slide grooves 502, so that when a fire occurs due to a fault in the transformer body 1, the internally provided detection belt 506 will be melted by high temperature, and the stabilizing frame 501 will be pulled away from the transformer body 1 by the tension spring 503;
[0031] The transformer can input insulating oil into the interior of the transformer body 1 through the storage tank 4. Through the input and circulation of the insulating oil, it can maintain stable performance in long-term operation and improve the heat dissipation performance. At the same time, when a transformer fails and a fire occurs, the flow of the insulating oil can be automatically disconnected, and the storage tank 4 can be kept away from the transformer body 1, thereby improving safety and avoiding the spread and aggravation of the fire. A reinforcing frame 505 is fixedly provided at the lower end of the support slide rail 504 to improve the stability of the support slide rail 504.
[0032] An extrusion tube 302 is fixedly provided on one side of the first connector 301, and the first connector 301 is magnetically connected to the second connector 308, which facilitates the separation and combination between the first connector 301 and the second connector 308. An inner support frame 307 is fixedly provided on one side of the second connector 308, and two support columns 305 are fixedly provided on one side of the inner support frame 307. A sliding plate 304 is slidably provided between one side of the two support columns 305, so that the sliding plate 304 can slide on the support column 305, thereby improving the stability of the sliding plate 304. A circulation groove 303 is provided inside the second connector 308, and support springs 306 are fixedly connected between the sliding plate 304 and the inner support frame 307 near the two sliding plates 304, so that when the sliding plate 304 overlaps with the circulation groove 303, the space between the first connector 301 and the second connector 308 is connected, thereby realizing the transmission of insulating oil, and when misaligned, the transmission of insulating oil will be isolated, thereby improving safety. The storage tank 4 is fixedly provided at the upper end of the two stabilizing frames 501, thereby facilitating the storage tank 4 to move to a safe position.
[0033] Working principle: When a fire occurs due to a fault in the transformer body 1, the detection belt 506 arranged inside will be melted by high temperature. When the detection belt 506 melts, the force on both sides of the stabilizing frame 501 will change, so that the tension spring 503 will be pulled away from the transformer body 1. At the same time, when the stabilizing frame 501 is pulled, the storage tank 4 will be moved and the connecting mechanism 3 will be separated. When the connecting mechanism 3 is separated, the position of the internal sliding plate 304 and the flow groove 303 will change from overlap to misalignment, and then the space between the first connector 301 and the second connector 308 will no longer be conductive, so that the transmission of insulating oil is isolated, the safety is improved, and the spread and aggravation of the fire are avoided.
[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
