Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-7 This invention provides a technical solution: a high-voltage outgoing line protection device for an oil-immersed transformer with an intelligent protection structure, such as... Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, the structure includes an oil-immersed transformer structure 1, which includes a shock absorber 11. The upper side of the shock absorber 11 is threadedly connected to the oil-immersed transformer body 12. A high-voltage output terminal 13, a low-voltage output terminal 14, an oil level gauge body 15, and an oil storage tank 16 are fixed on the upper side of the oil-immersed transformer body 12. The high-voltage output terminal 13 is located behind the low-voltage output terminal 14. The oil level gauge body 15 is located to the right of the low-voltage output terminal 14, and the oil storage tank 16 is located to the left of the high-voltage output terminal 13. The oil storage tank 16 is connected to the oil-immersed transformer body 12. An auxiliary filter assembly 17 is fixed on the outer wall of the oil-immersed transformer body 12. The lower side of the auxiliary filter assembly 17 is connected to an oil purifier 18. The oil purifier 18 is connected to the oil-immersed transformer body 12 through a second oil pipe 19. The auxiliary filtration assembly 17 includes a first oil pipe 171, which connects the oil-immersed transformer body 12 and the filter pipe 172. A drive motor housing 173 is fixed on the filter pipe 172. The motor in the drive motor housing 173 drives the screw rod 174 to rotate. The screw rod 174 is located inside the filter pipe 172. The filter screen 175 passes through the lower side of the inside of the filter pipe 172. The lower left end of the inside of the filter pipe 172 is connected to the discharge pipe 176. The lower side of the discharge pipe 176 is connected to the waste storage bottle 177. The lower side of the filter pipe 172 is connected to the guide trough 178. The guide trough 178 is threadedly connected to the oil purifier 18 through a hollow threaded connector 179. The oil purifier 18 is connected to the oil-immersed transformer body 12 through a second oil pipe 19.

[0036] Among them, four sets of hollow threaded blocks are fixed on the lower side of the oil-immersed transformer body 12. Each set of hollow threaded blocks has a threaded rod that can be installed and removed by threads. An electric telescopic rod is fixed on the lower side of the threaded rod, and a roller is fixed on the lower side of the electric telescopic rod. The setting of four sets of rollers makes it easy to move the entire device without manual handling. The threaded rod can be directly removed from the hollow threaded block, and the roller can be directly removed. The operation is simple and convenient.

[0037] Specifically, four sets of shock absorbers 11 are provided. The four sets of shock absorbers 11 are symmetrically arranged about the central axis of the oil-immersed transformer body 12. The four sets of shock absorbers 11 are disassembled and installed on the oil-immersed transformer body 12 by bolts. The discharge pipe 176 and the waste storage bottle 177 are threadedly connected. The waste storage bottle 177 is separated from the discharge pipe 176, so that impurities in the waste storage bottle 177 can be processed. A transparent observation port is passed through the waste storage bottle 177 for easy observation by the staff.

[0038] In the above scheme, the shock absorber 11 plays a buffering and shock-absorbing role with the assistance of the oil level gauge body 15 on the oil-immersed transformer body 12. The oil level gauge body 15 on the oil-immersed transformer body 12 provides real-time monitoring of the internal oil. The oil storage tank 16 replenishes the oil in the oil-immersed transformer body 12 in a timely manner when the oil level is insufficient. The oil enters the filter pipe 172 through the first oil pipe 171 with the assistance of the pressure pump on the first oil pipe 171. Impurities in the oil are pre-treated by the filter screen 175 inside the filter pipe 172. The drive motor... With the assistance of the motor inside the box 173, the screw rod 174 is driven to rotate. The rotation of the screw rod 174 causes the impurities in the discharge pipe 176 to move. The impurities are stored in the waste storage bottle 177 through the discharge pipe 176. The filtered oil enters the oil purifier 18 through the guide trough 178 and the hollow threaded connector 179. With the assistance of the oil purifier 18, the oil is filtered. The filtered oil flows back to the oil-immersed transformer body 12 through the second oil pipe 19, reducing the number of oil replacements and increasing practicality.

The auxiliary heat dissipation component 22 includes a first motor housing 221. The motor in the first motor housing 221 drives the heat dissipation fan blades 222 to rotate.

[0040] Among them, the control device for the overall equipment is fixed on the top cover 216, and four sets of the first protective net 212 and the second protective net 213 are provided. The four sets of the first protective net 212 and the second protective net 213 are symmetrically arranged about the central axis of the oil-immersed transformer body 12.

[0041] Furthermore, seven sets of threaded holes 215 are equally spaced on the sliding support rod 214, and two sets of threaded holes 215 are passed through the first fixed rod 211. The sliding support rod 214 inside the first fixed rod 211 slides to the desired position, and the bolt is rotated and fixed through the threaded hole 215, thereby adjusting the position of the top cover 216 and the second protective net 213.

[0042] Specifically, a wire hole is provided on the first protective net 212 on the rear side, and an annular limiting plate is embedded in the wire hole. Multiple sets of ball bearings are rotatably connected on the annular limiting plate, and the ball bearings are set to protect the cable.

[0043] In the above scheme, the staff pulls the top cover 216 on the sliding support rod 214, and the sliding support rod 214 slides on the first fixed rod 211 to the desired position. The bolt is passed through the threaded hole 215 on the first fixed rod 211 and the sliding support rod 214 and rotated to fix it, thereby adjusting the position of the second protective net 213 and the top cover 216, increasing the internal space. With the assistance of the motor in the first motor box 221, the heat-dissipating fan blades 222 are driven to rotate. The rotation of the heat-dissipating fan blades 222 provides auxiliary heat dissipation for the high voltage output terminal 13 and the low voltage output terminal 14. The small camera 23 is set up to monitor the on-site environment in real time and transmit the video in case of an emergency, which is convenient for later analysis of the cause of the accident.

[0046] Furthermore, the fire extinguisher storage box 32 is rotatably connected to a sealing cover, which facilitates the replacement of the fire extinguisher 33 in the future;

[0047] In the preferred embodiment, when a fire occurs at the high-voltage output terminal 13 and the low-voltage output terminal 14, the electric valve of the fire extinguisher 33 in the fire extinguisher storage box 32 on the first support frame 31 is opened. The extinguishing agent in the fire extinguisher 33 enters the high-voltage discharge nozzle 35 through the delivery pipe 34. With the assistance of the high-voltage discharge nozzle 35, the fire at the high-voltage output terminal 13 and the low-voltage output terminal 14 on the upper side of the oil-immersed transformer body 12 is extinguished, preventing the fire from spreading and causing further unnecessary losses.

[0048] like Figure 1 , Figure 2 ... Figure 4 ,Figure 1 , Figure 2 and Figure 4 Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 7 As shown, the right side of the oil-immersed transformer structure 1 has a fixed energy-saving structure 4, which also serves to save energy.

The energy-saving component 43 includes a photovoltaic panel 431. The photovoltaic panel 431 is electrically connected to a storage battery 432.

[0049] The first fixing plate 411 and the second fixing plate 415 have the same length. The motor in the second motor box 412 is a stepper motor, which is existing technology.
