[0024] First embodiment:

[0025] like Figure 1-4As shown, the oil-immersed transformer with oil purification device provided by the utility model comprises: an oil-immersed transformer 100, a mounting assembly 200 is arranged at one end of the oil-immersed transformer 100, the mounting assembly 200 is detachably mounted on one side of the oil-immersed transformer 100 by bolts, and a detachable oil purification filter element 300 is arranged at one end of the mounting assembly 200, the mounting assembly 200 comprises a mounting seat 201, a mounting tube 206 is detachably arranged on the upper end surface of the mounting seat 201, and a vertically arranged There is a side plate 202, a side seat 208 is assembled on the side of the side plate 202, a backing plate 209 is installed on the side of the side seat 208, a notch is opened on the side seat 208, and an ear plate 211 is slidably arranged in the notch, a threaded rod 210 is rotatably arranged on the backing plate 209, and the threaded rod 210 is meshed with the ear plate 211. In actual use, when the user assembles the oil purification filter element 300, one end of the oil purification filter element 300 is passed through the installation tube 206 and the two ends of the installation tube 206 are opened. At this time, the oil purification filter element 300 is used. The user can connect the oil purification filter element 300 with the oil inlet of the oil-immersed transformer 100. When the user needs to inject insulating oil into the oil-immersed transformer 100, the insulating oil can be purified by injecting the insulating oil into the oil purification filter element 300. When the oil purification filter element 300 is connected with the oil inlet of the oil-immersed transformer 100, the user rotates the threaded rod 210 on the pad 209, and the threaded rod 210 is engaged with the ear plate 211, and the side The seat 208 limits the ear plate 211, so that the ear plate 211 can be moved vertically downward perpendicular to the side seat 208. The user rotates the threaded rod 210 until the ear plate 211 passes through the slot 207 and abuts against the side wall of the oil purification filter element 300, thereby achieving the tight abutment and limitation of the upper end of the oil purification filter element 300 by the ear plate 211. The oil purification filter element 300 is surrounded by the mounting tube 206 and the ear plate 211 is tightly abutted against the oil purification filter element 300, thereby finally achieving the rapid installation of the oil purification filter element 300.

[0026] By means of the provided installation component 200, the oil purification filter element can be quickly installed, and the provided installation component 200 can ensure that the oil purification filter element 300 is firmly clamped on the side of the oil-immersed transformer 100, thereby eliminating the need to disassemble and reconnect the pipeline, which can greatly simplify the installation process and reduce the time and labor required for the installation of the oil purification filter element. At the same time, by means of the provided installation component 200, the oil purification filter element 300 can be firmly fixed on the side of the oil-immersed transformer 100, reducing the risk of the oil purification filter element 300 loosening or falling, thereby improving the safety of oil purification and reducing accidents or injuries that may be caused by the oil purification filter element 300 during operation.

[0027] Second embodiment:

[0028] like Figure 2-3 As shown, the mounting tube 206 is an annular pipe and is penetrated at both ends; the oil-immersed transformer 100 is formed with an oil inlet for infusing insulating oil, and one end of the mounting tube 206 is connected to the oil inlet.

A clamping plate 205 is slidably provided in the positioning shaft 203, and the clamping plate 205 abuts against one end of the positioning bolt 204. When in use, the user rotates the positioning bolt 204 so that the set positioning bolt 204 can move downward in the clamping plate 205. When the end of the positioning bolt 204 contacts the clamping plate 205, at this time, as the positioning bolt 204 moves downward, the clamping plate 205 can gradually move downward, thereby achieving the squeezing and fixation of the mounting tube 206.

[0032] Fourth embodiment:

Through the limit blocks 212 set at the bottom of the mounting tube 206, the user places the mounting tube 206 on the mounting seat 201 and makes the bottoms of the limit blocks 212 abut against the mounting seat 201. At this time, the user can move the clamp 205 downward by rotating the positioning bolts 204 until it is tightly against the limit blocks 212. At this time, the user can rotate the four positioning bolts 204 in sequence to achieve the tight fixation of the limit blocks 212 and the installation of the mounting tube 206 on the mounting seat 201.

[0034] By using the limit block 212 in cooperation with the clamping plate 205, when the user needs to replace the size of the oil purification filter element 300 and the size of the oil purification filter element 300 is larger than the surrounding diameter of the mounting tube 206, the user can disassemble the mounting tube 206 and replace it with a mounting tube 206 that is compatible with the oil purification filter element 300, thereby ensuring the assembly and use of different models on the side of the oil-immersed transformer 100.
