Embodiment 1
[0034] Such as figure 1 As shown, a transformer body kerosene vapor phase cleaning and drying system includes a drying tank 16, a kerosene steam generator 2, an ion generator 18, a filter 1, a steam collection tank 3, and a vacuum device 4.
[0035] The kerosene steam generator 2 is located outside the drying tank 16 and communicates with the drying tank 16 through a first pipeline 6 , and a first pneumatic valve 10 is arranged on the first pipeline 6 .
[0036] The ion generator 18 is located outside the drying tank 16, and communicates with the drying tank 16 through a second pipeline 19. The second pipeline 19 is provided with a second pneumatic valve 17; the second pipeline 19 communicates with several branch pipelines, and each branch pipeline is provided with The sixth pneumatic valve 13, the ends of each branch pipe are connected to the serpentine pipe 14, and each serpentine pipe 14 is arranged in the drying tank 16; coverage.
[0037] The filter 1 is located outside...
Embodiment 2
[0043] The method for cleaning and drying the transformer body by using the kerosene vapor phase cleaning and drying system for the transformer body in Example 1, the specific steps are:
[0044] 1) Put the transformer to be cleaned and dried in the drying tank, and close the drying tank;
[0045] 2) Open the fifth pneumatic valve, close the first pneumatic valve, the second pneumatic valve, the third pneumatic valve and the fourth pneumatic valve, open the vacuum device, and vacuum the drying tank to keep the pressure inside the drying tank at 20-50Pa ;
[0046] 3) Open the first pneumatic valve and the second pneumatic valve, close the fifth pneumatic valve, respectively feed kerosene vapor and positive and negative ion airflow into the drying tank; and impurities such as dust, oil, insulation processing residue powder, metal particles, and semiconductor particles adsorbed on the transformer body due to static electricity. After the kerosene vapor is condensed, the impuriti...
