[0040] according to Figure 1-Figure 4 and Figure 6-Figure 8As shown, the bottom of the upper rectangular plate 105 contacts the top of the separator 116, the bottom of the lower sealing ring 117 contacts the top of the lower rectangular plate 105, the bottom of the lower separator 116 contacts the top of the lower rectangular plate 105, and the outer surface of the separator 116 is movably sleeved with a rectangular graphite ring 118, and the top of the rectangular graphite ring 118 contacts the bottom of the upper rectangular plate 105, so that under the action of the rectangular graphite ring 118, the heat transfer speed of the insulating oil can be increased, and the transformer can have the function of electromagnetic shielding.

[0041] according to Figure 1-Figure 7 and Fig. 9 As shown, two limit blocks 119 are installed at the bottom of the upper rectangular plate 105, and two mounting blocks 120 are installed at the top of the lower rectangular plate 105. An iron core 121 is arranged between the inside of the two limit blocks 119 and the inside of the two mounting blocks 120. A primary winding 122 is wound on the iron core 121, and a secondary winding 123 is wound on the iron core 121. With the cooperation of the primary winding 122, the iron core 121, the secondary winding 123 and the bushing 106, high-voltage alternating current can be converted into low-voltage alternating current.

[0042] according to Figure 1-Figure 7 and Fig. 9 As shown, the primary winding 122 and the secondary winding 123 are symmetrically installed on the iron core 121, and the four sleeves 106 are divided into two groups. The bottom ends of the two groups of sleeves 106 are respectively connected to the two ends of the primary winding 122 and the two ends of the secondary winding 123. The tops of the two limit blocks 119 are movably penetrated by two symmetrical bolt rods 124. The four bolt rods 124 are divided into two groups.

A filter screen 126 is slidably embedded in the top of the liquid storage box 110, and the top end of the filter screen 126 is on the same horizontal plane as the top end of the liquid storage box 110, so that impurities in the insulating oil can be filtered out in the filter screen 126 and retained in the liquid storage box 110.

[0043] The effect achieved by the entire mechanism is: when a single-phase transformer is needed, the entire single-phase transformer is first installed at the desired location using two mounting frames 101, and then the temperature sensor 107, four fans 104, the oil pump body 113, the first electric valve 203, the second electric valve 207, the first oil pump 204, the second electric valve 207, the second oil pump 208, the third electric valve 210, the fourth electric valve 212 and the vacuum pump 215 are electrically connected to the prepared PLC controller, and then the PLC controller is connected to an external power supply, and then the PLC controller is turned on, and the temperature threshold and the use program are set. When everything is ready, the top of a group of sleeves 106 connected to the primary winding 122 is directly connected to the conveying The wires of high-voltage alternating current are connected together, and the top of a group of bushings 106 connected to the secondary winding 123 is connected to the wires of the output low-voltage alternating current. At this time, with the cooperation of the primary winding 122, the iron core 121, the secondary winding 123 and the four bushings 106, the high-voltage alternating current transmitted is directly converted into low-voltage alternating current. At the same time, the oil pump body 113 and the four fans 104 are started by the prepared PLC controller. At this time, the started oil pump body 113 will directly extract the insulating oil in the liquid storage box 110 with the cooperation of the second oil pipe 115, and then introduce it into the interior of the third oil pipe 125, and then transport it to the interior of the first oil pipe 114, and then transport it to the interior of the space composed of the shell 102 and the two rectangular plates 105. When When the insulating oil in the first oil pipe 114 is continuously transported to the above-mentioned space, the insulating oil previously stored in the space will directly enter the L-shaped tube 112, and then be transported to the liquid storage box 110, and then enter the filter 126 for filtration, and then enter the second oil pipe 115. This reciprocating process can remove impurities from the transformer, thereby improving the safety and reliability of the single-phase transformer. At the same time, the heat generated by the internal components of the transformer during operation will be directly transferred to the insulating oil. Then, with the cooperation of the partition block 116, the rectangular graphite ring 118 and the housing 102, the heat in the insulating oil can be quickly and directly transferred to the heat sink 103, and then dissipated to the environment. When the temperature sensor 107 passes through the prepared P When the LC controller cooperates with the insulation oil in the transformer and detects that the temperature of the insulation oil in the transformer is higher than the temperature threshold value set in advance by the PLC controller, in order to quickly discharge the heat in the insulation oil on the transformer, when the insulation oil in the transformer is detected to be higher than the temperature threshold value set in advance by the PLC controller, the PLC controller will directly start four fans 104, and use the cooperation of the fans 104 to improve the heat dissipation effect of the transformer, that is, the insulation oil in the transformer can be returned to a suitable temperature in a very short time, thereby achieving energy saving. At the same time, under the action of the rectangular graphite ring 118, the electromagnetic radiation generated by the transformer during use can be shielded to avoid the radiation generated by the transformer from affecting people or the environment. When the single-phase transformer is used for a long time,At this time, the transformer will produce hydrogen, methane, ethane and other gases, and these gases will directly dissolve in the insulating oil. If you want to remove these gases in the insulating oil, the PLC controller is used to close the oil pump body 113, and then the second oil pump 208, the third electric valve 210 and the fourth electric valve 212 are opened. The started second oil pump 208 will directly extract the insulating oil in the space formed by the shell 102 and the two rectangular plates 105 with the cooperation of the liquid outlet pipe 211, and then transport it to the inside of the third electric valve 210, and then transport it to the inside of the second oil inlet pipe 209, and then transport it to the inside of the second oil outlet pipe 213, and then transport it to the inside of the fourth electric valve 212, and then transport it to the connected The inside of the round tube 202 is finally transported to the inside of the degassing container 201 (transparent container). When a proper amount of insulating oil is poured into the inside of the degassing container 201, the second oil pump 208, the third electric valve 210 and the fourth electric valve 212 are directly closed by the PLC controller, and then the vacuum pump 215 is started by the PLC controller. At this time, the started vacuum pump 215 will first extract the air in the degassing container 201 with the cooperation of the connecting pipe 216 and the air outlet pipe 214. When the inside of the degassing container 201 forms a vacuum state, the gas in the insulating oil in the degassing container 201 will gradually separate from the insulating oil under the vacuum state, and then be transported to the air outlet pipe 214, and then transported to the inside of the connecting pipe 216. Then it is discharged from the output end of the vacuum pump 215. When the gas inside the degassing container 201 is extracted for a period of time, the vacuum pump 215 is directly turned off by the PLC controller, and then the first oil pump 204, the first electric valve 203, the oil pump body 113 and the second electric valve 207 are opened by the PLC controller. At this time, the started first oil pump 204 will directly extract the treated insulating oil in cooperation with one of the circular tubes 202, the first electric valve 203 and the first oil inlet pipe 205, and then the extracted insulating oil will be directly transported to the liquid storage box 110 in cooperation with the first oil outlet pipe 206 and the second electric valve 207. At this time, the started oil pump body 113 will also, with the cooperation of the second oil pipe 115, pump the liquid storage box 110. 0 is extracted and directed to the third oil pipe 125, that is, to prevent the amount of insulating oil collected by the liquid storage box 110 from being too much, resulting in expansion and damage of the liquid storage box 110. When the treated insulating oil in the degassing container 201 is completely extracted, the first oil pump 204, the first electric valve 203, the oil pump body 113 and the second electric valve 207 are directly closed by the PLC controller. Then, the above steps are repeated several times to remove most of the gas dissolved in the insulating oil in the transformer, thereby improving the service life and use effect of the transformer insulating oil. When the insulating oil in the transformer is almost treated, the PLC controller is directly used to start only the oil pump body 113, and the temperature sensor 107 is used to monitor the temperature of the insulating oil in the transformer.Thus, it is sufficient to control whether the four fans 104 are turned on or off.

[0044] Among them, the fan 104, the temperature sensor 107, the oil pump body 113, the rectangular graphite ring 118, the iron core 121, the primary winding 122, the secondary winding 123, the first electric valve 203, the first oil pump 204, the second electric valve 207, the second oil pump 208, the third electric valve 210, the fourth electric valve 212 and the vacuum pump 215 are all existing technologies and will not be explained in detail here.
