Description

Technical Field

[0001] This invention relates to the field of transformer technology, specifically to a transformer cooling oil guiding system and cooling method. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. Its main functions are voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. It is a basic piece of equipment for power transmission and distribution and is widely used in industry, agriculture, transportation, urban communities, and other fields.

[0003] During operation, existing transformers generate a significant amount of heat due to their internal resistance. To effectively dissipate this heat and ensure stable power supply, oil is typically pre-filled inside the transformer tank to cool and insulate the resistors. While this method provides heat dissipation, it has significant drawbacks in practical use, such as: While the oil inside the transformer tank is being cooled, it is also being continuously heated. Simply relying on the fins on the surface of the transformer tank for heat dissipation is undoubtedly too simplistic. Furthermore, in hot weather and environments, natural heat dissipation is significantly less efficient, which can negatively impact the transformer itself.

[0004] Therefore, a transformer cooling oil diversion system that can improve heat dissipation efficiency has been designed to address these shortcomings. Summary of the Invention

A suction pipe is fixedly connected to the inlet of the material pump, and the end of the suction pipe away from the material pump passes through the load-bearing bottom frame and extends into the interior of the load-bearing bottom frame. A pressure pipe is fixedly connected to the outlet of the material pump, and the end of the pressure pipe away from the material pump passes through the liquid storage tank and extends into the interior of the liquid storage tank.

[0009] Preferably, a return liquid frame is fixedly connected to the upper part of the surface of the liquid storage tank through an opening. The front end of the return liquid frame penetrates through the transformer box and extends into the interior of the transformer box. A sloping baffle is fixedly connected to the top of the liquid storage tank through an opening. A filter screen is provided inside the sloping baffle. A protective baffle that cooperates with the filter screen is rotatably connected to the left side of the sloping baffle.

[0010] Preferably, a curved guide tube is fixedly connected to the upper part between the two sides of the inner cavity of the liquid storage tank through an opening, and both ends of the curved guide tube extend to the bottom of the liquid storage tank. A vertical air pipe is fixedly connected to the bottom of the curved guide tube and located inside the liquid storage tank through an opening, and several vertical air pipes are provided.

[0011] Preferably, a fan is fixedly connected to the surface of the load-bearing base frame via a bracket, and a second heat dissipation pipe is fixedly connected to the surface of the load-bearing base frame through an opening. Several second heat dissipation pipes are provided. The rear end of the second heat dissipation pipe passes through the load-bearing base frame and extends to the rear part of the load-bearing base frame. A buffer baffle is fixedly connected to the top and bottom of the second heat dissipation pipe and to the inner side of the load-bearing base frame. An air outlet pipe that cooperates with the second heat dissipation pipe is fixedly connected to the rear part of the fan.

[0012] Preferably, an X-shaped plate is fixedly connected to the inner side of the second heat dissipation pipe, a wind shroud is fixedly connected to the rear end of the second heat dissipation pipe, a straight air guide pipe is fixedly connected to the rear end of the wind shroud, and the end of the straight air guide pipe away from the wind shroud is connected to a curved guide pipe frame.

[0013] This invention also discloses a cooling method for a transformer cooling oil guiding system, specifically including the following steps: S1. Preparation process: Install the transformer body inside the transformer box and inject oil at the same time; S2, Oil cooling: The oil is circulated and cooled using a material pump; S3, Exhaust return: Use gas to dissipate heat from the oil and then discharge it through the filter screen.

[0014] Beneficial effects This invention provides a transformer cooling oil flow guiding system and cooling method. Compared with existing technologies, it has the following advantages: (1) The transformer cooling oil guiding system and cooling method are used by installing a load-bearing bottom frame at the bottom of the transformer box and installing a second heat dissipation pipe inside the load-bearing bottom frame, combined with an X-shaped plate and a fan. The structure can slow down the flow speed of the oil by using a buffer baffle after it reaches the inside of the load-bearing bottom frame, and then let the fan blow air inside the second heat dissipation pipe to carry away the heat. At the same time, the X-shaped plate can effectively increase the contact area with the air and improve the heat dissipation efficiency.

[0015] (2) The transformer cooling oil guiding system and cooling method are used by installing a liquid storage tank at the rear of the transformer box, and using a curved guide tube frame, a vertical air pipe and a filter screen. The structure can inject the cooled oil into the interior of the liquid storage tank and guide the airflow inside the second heat dissipation pipe to the bottom of the oil. The force generated by the airflow will make the oil roll. As the airflow and bubbles rise, some heat will be carried out again. Then the airflow will be discharged from the filter screen, which improves the energy utilization rate and performs secondary heat dissipation on the oil.

[0016] (3) The transformer cooling oil diversion system and cooling method are provided by installing a protective baffle that works in conjunction with the filter screen on one side of the inclined baffle frame. The design of these structures can first protect the inside of the liquid storage tank by using the filter screen and the protective baffle to prevent impurities and insects from entering. At the same time, the protective baffle can be opened to exhaust air when the airflow rises, thus ensuring the stability of the equipment during operation. Attached Figure Description

[0022] This invention also discloses a cooling method for a transformer cooling oil guiding system, specifically including the following steps: S1. Preparation process: Install the transformer body 103 inside the transformer box 102 and inject oil at the same time; S2, Oil cooling: The material pump 107 is used to circulate the oil and cool it. S3, Exhaust return: Use gas to dissipate the heat in the oil, and then discharge it through the filter screen 112.

[0023] The cooling method of the above-mentioned transformer cooling oil guiding system includes the following more specific steps: S1. Preparation process: Before use, first install the transformer body 103 into the transformer box 102, then fill the transformer box 102 with oil. After the oil enters the transformer box 102, it will first enter the load-bearing bottom frame 201 through several liquid guide bottom pipes 105. Only after the load-bearing bottom frame 201 is filled will the transformer box 102 begin to store oil. After the oil is filled to the bottom of the return liquid frame 110, stop filling the oil. Then seal and install the entire equipment. S2. Oil Cooling: During use, after the transformer body 103 is started, it will first transfer heat to the oil. The setting of several first heat dissipation pipes 104 can dissipate the heat in the oil. At the same time, the fan 202 and the material pump 107 are started synchronously. After the material pump 107 is started, the oil inside the load-bearing bottom frame 201 is drawn out by the suction pipe 108. Then, the oil is injected into the interior of the storage tank 106 by the pressure pipe 109. At this time, the oil inside the transformer box 102 will enter the interior of the load-bearing bottom frame 201 again through the liquid guide bottom pipe 105. At this time, the start of the fan 202 blows air into the interior of the second heat dissipation pipe 203. When the air flows through the interior of the second heat dissipation pipe 203, the inner wall of the entire second heat dissipation pipe 203 and the X-shaped plate 206 increase the contact area with the air, thereby carrying out a large amount of heat in the oil. At the same time, when the suction pipe 108 draws out the oil, the function of several buffer baffles 204 can slow down the flow speed of the oil and improve the heat dissipation efficiency. S3, Exhaust and Recirculation: After the oil that has completed its initial heat dissipation is pumped into the return frame 110 by the material pump 107, the airflow inside the second heat dissipation pipe 203 is compressed by the air shroud 207 and then injected into the inside of the curved guide tube 114 through the straight air pipe 208. The rapidly flowing gas then enters the bottom of the liquid storage tank 106 through several vertical air pipes 115. After the airflow is released in the oil, the oil inside the liquid storage tank 106 will tumble, and a large number of bubbles will rise to the surface and burst, thereby releasing the heat in the oil again. Then the gas, carrying the heat, rises and pushes open the protective baffle 113 to discharge from the filter screen 112. As the oil inside the liquid storage tank 106 is continuously injected, it flows back into the transformer box 102 for cooling when it reaches the return frame 110.
