TECHNICAL FIELD
[0001] The present application relates to the technical field of transformers, in particular to an outdoor transformer with oil seepage prevention function. BACKGROUND
[0002] Outdoor oil-immersed transformers are widely used in power distribution systems, but they have long been plagued by oil seepage, leakage, rusting, and rainwater infiltration. Traditional oil-immersed transformers are prone to insulation oil leakage due to insufficient sealing, which not only pollutes the environment but also may cause fire or explosion accidents. In addition, rainwater, salt mist, dust, and other factors in outdoor environments can accelerate equipment corrosion, affecting heat dissipation efficiency and service life. New oil seepage prevention outdoor transformers achieve technological breakthroughs through structural innovation and material upgrading, eliminating oil storage tanks and using corrugated oil tanks or welded sealed tank bodies. They utilize metal elastic compensation to prevent oxygen and moisture from seeping in and delay insulation oil aging. To address the problem of rainwater infiltration, they increase rainwater collection boxes, elastic airbag sealing systems, and other devices to block the water intrusion path in real time. They integrate oil seepage early warning sensors that trigger alarms through pressure changes or abnormal oil levels, enabling early maintenance intervention. The oil tank sidewalls use corrugated sheet structures that automatically adjust internal oil pressure through elastic deformation, preventing sealing failure due to thermal expansion and contraction. At the same time, the tank covers and tank edges are welded or bolted to achieve a fully enclosed structure, completely eliminating the risk of oil leakage. Oil seepage holes and spiral tubes are set at the bottom of the transformer, and when the oil pressure is abnormal, the cooling oil flows into the load-bearing piston to trigger the pressure-sensitive sensor alarm. For high-salt-mist coastal environments, the tank body is made of stainless steel and coated to improve corrosion resistance.
[0003] Outdoor oil-immersed transformers mainly consist of an oil tank (filled with insulation oil), a core, windings, a heat dissipation system, and protection devices. They rely on transformer oil for insulation and cooling, and the oil tank's sealing directly affects the device's reliability. The repeated expansion and contraction of the oil volume caused by day-night temperature differences can easily cause the traditional oil storage tank to absorb moisture, reducing insulation performance.

[0012] The application provides an outdoor transformer with an oil seepage prevention function.
[0013] 1. The outdoor transformer with oil seepage prevention function is provided with a top cover, the top of the top cover is shielded from rain and other external substances, and the rain is guided through the inclined flow guide groove, thereby reducing the leakage problem caused by the accumulation of rain on the top of the top cover causing the metal to rust, when the temperature difference between the inside and outside of the box occurs, the pressure of the internal gas and the external gas loses balance, thereby driving the flexible waterproof sheet to deform, thereby absorbing the pressure caused by the pressure imbalance of the gas within a certain range through the deformation degree of the flexible waterproof sheet, and absorbing the elastic force caused by the deformation of the flexible waterproof sheet through the spring sheet, thereby facilitating the recovery of the original state after maintenance to return to the balanced state, thereby facilitating the balance of internal and external pressure, and the downward inclination of the flexible waterproof sheet reduces the possibility of accumulation of rain and other substances on the outer side of the flexible waterproof sheet, thereby facilitating the maintenance of the outer side of the flexible waterproof sheet, thereby facilitating the maintenance of the state of the box outside.
[0014] 2.

[0015] 3. This outdoor transformer with oil-proof function is equipped with a first motor. The drive shaft of the first motor rotates, driving the arc-shaped blades to rotate. The rotation of the arc-shaped blades drives the guide blades to rotate, which in turn drives the diversion tip to rotate. The rotation of the guide blades inside the first conical tube diverts the liquid through the diversion tip, causing it to flow along the side of the guide blades and into the second conical tube. This allows the liquid to pass through the second conical tube and into the heat dissipation pipe, facilitating cooling. The rotation of the arc-shaped blades also causes air to flow, passing through the side of the second conical tube and further cooling the liquid. The heat dissipation fins reinforce the heat dissipation pipe and increase the contact area between the pipe and the air, improving heat dissipation efficiency. The combination of the second conical tube and the heat dissipation pipe changes the fluid cross-sectional area, increasing the liquid flow velocity inside the second conical tube and further enhancing heat dissipation efficiency.

The cooling liquid enters the distribution pipe through the delivery pipe and flows out from the side of the drain hole, thus completing the circulation of liquid inside the tank. This facilitates heat dissipation inside the tank. The delivery pipe also allows the liquid to flow from top to bottom and return to the guide pipe, facilitating the circulation of liquid between the upper and lower parts of the tank. This ensures that the liquid flows throughout the entire tank, maintaining a constant temperature between the tank and the outside environment, thereby preventing leakage caused by tank deformation.
