[0047] In the embodiment of the present invention, when the electromagnet 523 is energized, the electromagnet 523 is magnetically fitted with the magnetic ring 532, and the limit pin 531 passes through the plug hole 524 and the limit hole 66.

[0048] See also Figure 1 , Figure 4 and Fig.10 In one embodiment of the present invention, the bearing member 43 includes a bearing grid 431, a telescopic tube 432 and a first spring 433. The bearing grid 431 is fixedly connected to the telescopic tube 432. The bottom of the capacitor core 1 is overlapped on the surface of the bearing grid 431. The telescopic tube 432 is movably sleeved in the fixed tube 421. The first spring 433 is connected between the bearing grid 431 and the heat dissipation frame 42.

[0049] In an embodiment of the present invention, the capacitor core 1 is placed in the protective shell 2, the bottom of the capacitor core 1 is overlapped on the surface of the bearing grid 431, and the capacitor core 1 is pressed downward. The first spring 433 is in a compressed state. At this time, the bottom of the capacitor core 1 is in contact with the annular heat sink 422, the radial heat sink 423 and the bearing grid 431 at the same time. The driving unit 51 is used to control the pressing block 65 and the heat conducting rod 61 to separate from the capacitor core 1. At this time, the upward elastic force of the first spring 433 drives the bearing grid 431 and the capacitor core 1 to rise to a certain height. At this time, the capacitor core 1 protrudes upward from the protective shell 2 by a certain distance, which is convenient for the staff to take it out.

[0050] Working principle: When installing the capacitor core 1, first use the control module to control the electromagnet 523 to cut off the power. Since the electromagnet 523 loses the magnetic attraction to the magnetic ring 532 after the power is cut off, the elastic force of the second spring 533 drives the lifting ring 53 to contact the ventilation frame 411. At this time, the limiting pin 531 is separated from the plug hole 524 and the limiting hole 66, and the limiting rod 534 is still in the guide hole 67 on the surface of the heat conducting rod 61. The limiting rib 413 on the surface of the ventilation frame 411 enters the limiting groove 535 on the inner wall of the lifting ring 53. In this way, the lifting ring 53 cannot surround the fixed tube 42 1 is rotated, and then the control module is used to control the driving unit 51 to start, and the driving unit 51 drives the rotating shell 52 to rotate through the gear ring 521. The rotating rotating shell 52 drives the sector block 62 from the contact position with the groove of the toothed guide rail 522 to the contact position with the protrusion by the way of sliding connection between the toothed guide rail 522 and the sector block 62. At this time, the limit rod 534 is slidably connected with the guide hole 67, so as to drive the pressing block 65 and the heat-conducting rod 61 to move together in the direction close to the protective shell 2, and the elastic sheet 64 is squeezed between the heat-conducting rod 61 and the protective shell 2;

[0051] Next, the capacitor core 1 is placed in the protective housing 2, the bottom of the capacitor core 1 overlaps the surface of the bearing grid 431, and the capacitor core 1 is pressed downward. The first spring 433 is in a compressed state, and the driving unit 51 is used to control the rotating shell 52 to continue to rotate at the same angle. The rotating rotating shell 52 drives the sector block 62 from the position in contact with the protrusion of the toothed guide rail 522 to the position in contact with the groove by means of a sliding connection between the toothed guide rail 522 and the sector block 62. The elastic deformation of the elastic sheet 64 drives the pressing block 65 and the heat conducting rod 61 to move toward the near The capacitor core 1 moves in the direction of the pressure block 65 and the heat conducting plate 63, respectively, so that the capacitor core 1 can be fixed in the protective shell 2. When the capacitor core 1 needs to be disassembled, the driving unit 51 is used again to control the pressure block 65 and the heat conducting rod 61 to separate from the capacitor core 1. At this time, the upward elastic force of the first spring 433 drives the supporting grid 431 and the capacitor core 1 to rise to a certain height. At this time, the capacitor core 1 protrudes upward from the protective shell 2 for a certain distance, which is convenient for the staff to take it out.

[0052] When the operating load of the capacitor core 1 is low or the internal temperature is lower than a certain threshold, the cooling fan module 412 is controlled to be turned on separately. After the cooling fan module 412 is turned on, the outside air enters the protective housing 2 from the cooling hole 22, and then is discharged from the cooling frame 42, the bearing grid 431 and the ventilation frame 411. Since the heat conducting sheet 63, the annular heat sink 422, the radial heat sink 423 and the bearing grid 431 are all in contact with the surface of the capacitor core 1, the heat on the surface of the capacitor core 1 can be directly conducted through the heat conducting sheet 63, the annular heat sink 422, the radial heat sink 423 and the bearing grid 431. When the cooled air passes through the heat conducting sheet 63, the annular heat sink 422, the radial heat sink 423 and the bearing grid 431, the cooling fan module 412 is turned on. 422, radial heat sink 423 and supporting grid 431, the heat can be quickly discharged to the outside. When the temperature sensor detects that the internal temperature of the protective shell 2 rises to a certain threshold, the circulating cooling module 32 and the heat dissipation fan module 412 are turned on at the same time. Since the circulating cooling module 32 can control the flow of low-temperature liquid in the threaded tube 31, when the outside air passes through the threaded tube 31, the low-temperature medium inside the threaded tube 31 can absorb the heat in the air to achieve the purpose of cooling the air. When the cooled air passes through the heat conductive sheet 63, the annular heat sink 422, the radial heat sink 423 and the supporting grid 431, the heat dissipation efficiency of the capacitor core 1 can be further accelerated.

[0053] In order to further improve the uniformity and efficiency of the cooling of the surface of the capacitor core 1, the control module is used to control the electromagnet 523 to be energized. After being energized, the electromagnet 523 is magnetically bonded to the magnetic ring 532. At this time, the moving lifting ring 53 drives the limiting pin 531 to re-enter the plug-in hole 524 and the limiting hole 66, and the limiting rib 413 on the surface of the ventilation frame 411 is disengaged from the limiting groove 535 on the inner wall of the lifting ring 53. In this way, the lifting ring 53 can rotate around the fixed tube 421. The control module is used to control the drive unit 51 to start. The drive unit 51 drives the rotating shell 52, the lifting ring 53, the limiting pin 531 and the dynamic heat conductive component 6 to rotate as a whole by a certain angle according to a certain frequency through the gear ring 521, so that the elastic sheet 64 is in uniform contact with the surface of the capacitor core 1.

[0054] In summary, the present application utilizes a structural design in which the air cooling system 4, the drive module 5 and the dynamic heat conductive component 6 cooperate with each other. (1) Since the heat conductive sheet 63, the annular heat sink 422, the radial heat sink 423 and the supporting grid 431 are all in contact with the surface of the capacitor core 1, the heat on the surface of the capacitor core 1 can be directly transferred through the heat conductive sheet 63, the annular heat sink 422, the radial heat sink 423 and the supporting grid 431. When the cooled air passes through the heat conductive sheet 63, the annular heat sink 422, the radial heat sink 423 and the supporting grid 431, the efficiency of cooling the surface of the capacitor core 1 is improved.

[0055] (2) The electromagnet 523 is energized. After being energized, the electromagnet 523 is magnetically bonded to the magnetic ring 532. At this time, the moving lifting ring 53 drives the limit pin 531 to enter the plug hole 524 and the limit hole 66. The control module is used to control the drive unit 51 to start. The drive unit 51 drives the rotating shell 52, the lifting ring 53, the limit pin 531 and the dynamic heat conduction component 6 to rotate as a whole at a certain angle through the gear ring 521 at a certain frequency, so that the elastic sheet 64 is in uniform contact with the surface of the capacitor core 1, thereby further improving the uniformity and efficiency of the cooling of the surface of the capacitor core 1.
