[0027] If the oil temperature is higher than the preset upper limit, the processor 52 sends a start signal to the refrigeration fin 308 in the temperature control bin 306 through the controller 53, and at the same time, the heating plate 307 is turned off to reduce the oil temperature. At this time, the cooling fan 309 may also be activated to accelerate the dissipation of heat. If the oil temperature is lower than the preset lower limit, the processor 52 sends a start signal to the heating plate 307 and turns off the refrigeration fin 308 to raise the oil temperature to the appropriate range. The temperature sensor 51 continuously monitors the change of the oil temperature, and the processor 52 adjusts the working state of the heating plate 307 and the refrigeration fin 308 in real time according to the feedback to ensure the stability of the oil temperature. When the oil temperature distribution is uneven or needs to quickly reach the set temperature, the processor 52 opens the electric valve 304 in the acceleration circulation subassembly 3 through the controller 53. Embodiment two
[0028] Based on the above embodiment 1, please refer to Figure 3 - Figure 5The intelligent detection assembly 5 comprises a temperature sensor 51, the temperature sensor 51 is installed on the inner wall of the oil-immersed transformer 1, and a processor 52 and a controller 53 are arranged at the lower portion of the temperature sensor 51.
[0029] The adapter pipes 21 are symmetrically arranged on one side of the oil-immersed transformer 1, the inner walls of the adapter pipes 21 and the inner wall of the oil-immersed transformer 1 are mutually penetrated, and the inner walls of the two adapter pipes 21 and the inner wall of the heat dissipation pipe 22 are mutually penetrated.
[0030] The communication pipe 41 is arranged at the top end of the oil-immersed transformer 1, the inner wall of the communication pipe 41 and the inner wall of the oil-immersed transformer 1 are mutually penetrated, the inner wall of the communication pipe 41 and the inner wall of the empty tank 42 are mutually penetrated, the two sides of the support frames 43 and the two sides of the empty tank 42 are fixedly connected, and the two sides of the support frames 43 and the two sides of the oil-immersed transformer 1 are fixedly connected.
[0031] The detection end of the temperature sensor 51 is arranged on the inner wall of the oil-immersed transformer 1, the temperature sensor 51 and the processor 52 are electrically connected, the controller 53 and the processor 52 are electrically connected, the controller 53 and the electric valve 304 are electrically connected, the processor 52 and the heating plate 307 and the refrigeration sheet 308 are electrically connected, and the heating plate 307 and the refrigeration sheet 308 and the controller 53 are electrically connected.
[0032] The gear pump 302 starts to work, oil is extracted from the lower portion of the oil-immersed transformer 1 through the connecting pipe 301, and the oil is transported to the coarse diameter pipe 305 after passing through the acceleration pipe 303. The design of the coarse diameter pipe 305 increases the flow area of the oil, reduces the flow rate, and helps the oil to fully contact with the heating plate 307 or the refrigeration sheet 308 in the temperature control bin 306, so that the temperature is quickly adjusted. The oil adjusted by the temperature control is returned to the inside of the oil-immersed transformer 1 through the fine diameter pipe 310, the design of the fine diameter pipe 310 increases the flow rate, and helps the oil to be distributed more quickly in the transformer. When the pressure in the transformer increases, the communication pipe 41 in the pressure reduction assembly 4 allows the oil to flow into the empty tank 42.
[0033] The working principle and the use process of the utility model are as follows: when the transformer is connected to the power supply, the temperature sensor 51 in the intelligent detection assembly 5 immediately starts to work, detects the temperature of the oil in the oil-immersed transformer 1, and transmits the data to the processor 52 in real time. The processor 52 evaluates the current oil temperature according to the preset oil temperature threshold range, and initializes the working state of each component.
[0034] If the oil temperature is higher than the preset upper limit, the processor 52 sends a start signal to the cooling fin 308 in the temperature control compartment 306 through the controller 53, while closing the heating plate 307 to reduce the oil temperature. At this time, the cooling fan 309 may also be activated to speed up the dissipation of heat. If the oil temperature is lower than the preset lower limit, the processor 52 sends a start signal to the heating plate 307 and closes the cooling fin 308 to raise the oil temperature to the appropriate range. The temperature sensor 51 continuously monitors the change of oil temperature, and the processor 52 adjusts the working state of the heating plate 307 and the cooling fin 308 in real time according to the feedback to ensure the stability of the oil temperature. When the oil temperature distribution is uneven or needs to quickly reach the set temperature, the processor 52 opens the electric valve 304 in the acceleration cycle assembly 3 through the controller 53.
[0035] The gear pump 302 starts to work, and the oil is extracted from the lower part of the oil-immersed transformer 1 through the connecting pipe 301. After passing through the acceleration pipe 303, the oil is transported to the coarse pipe 305. The design of the coarse pipe 305 increases the flow area of the oil, reduces the flow rate, and helps the oil to fully contact with the heating plate 307 or the cooling fin 308 in the temperature control compartment 306, realizing the rapid adjustment of temperature. The oil adjusted by temperature control flows back to the inside of the oil-immersed transformer 1 through the fine pipe 310. The design of the fine pipe 310 increases the flow rate, which helps the oil to be distributed more quickly inside the transformer. When the pressure inside the transformer rises, the communication pipe 41 in the pressure reduction assembly 4 allows the oil to flow into the empty tank 42 to reduce the pressure.
[0036] The heat dissipation pipe 22 in the natural circulation assembly 2 utilizes the principle of natural convection to help the oil to circulate naturally inside the transformer, which helps to maintain the stability of the oil temperature. The intelligent detection assembly 5 continuously monitors the oil temperature, and the processor 52 adjusts the working state of each assembly in real time according to the change of the oil temperature to ensure that the transformer always operates in the best working state.
