[0021] Example 1

[0022] See also Figure 1-4 The utility model provides the following technical solutions: a transformer with lightning protection function, comprising a shell 1, heat dissipation assemblies 3 are installed at the edge positions on both sides of the shell 1, a connecting column 4 is installed above the shell 1, two lightning rod assemblies 6 are arranged above the connecting column 4, lightning arresters 7 are installed on both sides away from each other between the two lightning rod assemblies 6, a grounding wire 8 is installed below the lightning arrester 7, a mobile drying device 2 is installed at the lower position of the shell 1, and the connecting column 4 and the two lightning rod assemblies 6 are connected through a rainwater collection device 5.

[0023] Specifically, the mobile drying device 2 includes a connecting plate 21, a drying component 22, a brake wheel 23 and a base 24.

The drying components 22 are installed at both ends of the connecting plate 21.

[0024] By adopting the above technical solution, the staff can move the position of the transformer to a certain extent through the brake wheel 23 when needed, thereby reducing the difficulty of moving the transformer and alleviating the labor burden of the staff.

[0025] Specifically, the drying component 22 includes a docking frame 222, a fixed net 223, a silica gel desiccant 224, a screw 225 and a knob 226. The screws 225 are threadedly installed at both ends of the connecting plate 21, the knob 226 is installed below the screw 225, the docking frame 222 is installed above the screw 225 and at a position located on the inner side of the shell 1, two fixed nets 223 are installed on the inner side of the docking frame 222, and the inner side of the docking frame 222 and a position located between the two fixed nets 223 are filled with silica gel desiccant 224.

[0026] By adopting the above technical solution, the transformer can prevent external moisture from entering the interior of the housing 1 through the heat dissipation vent assembly 3 through the cooperation of the fixed net 223 and the silica gel desiccant 224, thereby reducing the possibility of the transformer being damaged by moisture.

[0027] Specifically, the drying component 22 further includes a blocking block 221 , and the blocking block 221 is installed on the top of the docking frame 222 via threads.

[0028] By adopting the above technical solution, the staff can unscrew the blocking block 221 to replace the silica gel desiccant 224 when necessary, thereby reducing the difficulty of replacing the silica gel desiccant 224 and alleviating the labor burden of the staff.

[0029] When the present embodiment is used, when the transformer is needed, the transformer body is arranged inside the housing 1, the staff pushes the housing 1, moves the transformer to the working position by means of the brake wheels 23 under the base 24 in the mobile drying device 2, and then respectively rotates the knobs 226 in the two drying components 22, thereby driving the two screw rods 225 to rotate, the screw rods 225 are threadedly connected to the connecting plate 21, the screw rods 225 are bearing-connected to the docking frame 222, and the docking frame 222 is closely attached to the inner side of the housing 1, so that the two screw rods 225 respectively drive the two docking frames 2 22 moves until the two docking frames 222 are aligned with the two heat dissipation port assemblies 3. When moisture passes through the heat dissipation port assembly 3, the silica gel desiccant 224 between the two fixed nets 223 in the docking frame 222 can absorb the moisture, reducing the possibility of damage to the transformer due to moisture. Then it can be used. The staff can unscrew the blocking block 221 to replace the silica gel desiccant 224 when necessary. In addition, when encountering lightning, the lightning rod assembly 6 transfers the received charge to the lightning arrester 7, and finally flows into the underground through the grounding wire 8, thereby performing lightning protection work.

[0030] Example 2

[0031] The present embodiment is different from the first embodiment in that the rainwater collection device 5 includes a connection box 51 and a filter screen 52 , the connection column 4 and the two lightning rod assemblies 6 are connected via the connection box 51 , and the filter screen 52 is installed on the top of the connection box 51 .

[0032] By adopting the above technical solution, the staff can collect rainwater when necessary through the cooperation of the connection box 51 and the filter screen 52, so as to better meet the work needs during cleaning and the like.

[0033] Specifically, the rainwater collection device 5 also includes a threaded block 53, a threaded rod 54, a rotating plate 55 and a closing plate 56. The closing plate 56 is arranged on the inner side of the connecting box 51 and below the filter 52. The threaded rod 54 is installed below the closing plate 56 through a bearing. The rotating plate 55 is installed below the threaded rod 54. The threaded block 53 is installed through threads at the bottom of the connecting box 51 and on one side of the two rotating plates 55.

[0034] By adopting the above technical solution, the staff can close the filter screen 52 through the cooperation of the threaded rod 54 and the closing plate 56 when necessary, thereby preventing the evaporation of rainwater, and the staff can unscrew the threaded block 53 to release the rainwater.

[0035] When this embodiment is used, before it rains, the staff can simultaneously rotate the two rotating plates 55 in the rainwater collecting device 5, thereby driving the two threaded rods 54 to rotate simultaneously. The two screw rods 225 are threadedly connected to the connecting box 51, and the two screw rods 225 are bearing-connected to the closing plate 56, so the two threaded rods 54 drive the closing plate 56 to descend, and the filter screen 52 is no longer closed, and the rainwater passes through the filter screen 52 into the connecting box 51 for storage. After it rains, the staff can rotate the two rotating plates 55 in the opposite direction to make the closing plate 56 rise, thereby closing the filter screen 52 and preventing the rainwater from evaporating and losing. When necessary, the staff can unscrew the threaded block 53 to release the rainwater, thereby better meeting the work needs during cleaning and the like. The connecting column 4 serves to connect the shell 1 and the connecting box 51.

[0036] In the utility model, the shell 1, the heat dissipation port assembly 3 composed of a heat dissipation port, a filter, a handle, an iron block, and a magnet, the lightning rod assembly 6 composed of a base, a placement slot, a lightning rod body and a limit mechanism, and the structure and principle of the lightning arrester 7 have been disclosed in a transformer with a lightning protection function disclosed in Chinese patent application No. 201922402668.X. Its working principle is that when it is used, when lightning hits the lightning rod body, the lightning rod body transfers the received charge to the lightning arrester, and finally flows into the underground through the grounding wire. When the lightning rod body needs to be inspected and disassembled later, first pull the pull block upward, the pull block drives the limit plate to move upward, the limit plate squeezes the buffer spring to move, thereby separating the limit plate and the lightning rod body, and then rotate the movable plate, the movable plate drives the limit plate to rotate, and then pull the lightning rod body upward. When there is a lot of dust on the filter that needs to be cleaned, pull the handle, the handle drives the filter to move away from the shell, and the filter drives the iron block and the magnet to separate.

[0037] The working principle and use process of the utility model are as follows: when the transformer needs to be used, the transformer body is arranged inside the shell 1, and the staff pushes the shell 1, moves the transformer to the working position by means of the brake wheels 23 under the base 24 in the mobile drying device 2, and then respectively rotates the knobs 226 in the two drying components 22, thereby driving the two screws 225 to rotate, the screws 225 are threadedly connected to the connecting plate 21, the screws 225 are bearing-connected to the docking frame 222, and the docking frame 222 is tightly attached to the inner side of the shell 1, so the two screws 225 respectively drive the two docking frames 222 to move until the two docking frames 222 are aligned with the two heat dissipation port components 3, when moisture passes through the heat dissipation port component 3, the silica gel desiccant 224 between the two fixed nets 223 in the docking frame 222 can absorb the moisture, reducing the possibility of the transformer being damaged by moisture, and then it can be used, and the staff can unscrew the blocking block 221 when necessary. The silica gel desiccant 224 is replaced. In addition, when encountering lightning, the lightning rod assembly 6 transfers the received charge to the lightning arrester 7, and finally flows into the underground through the grounding wire 8, thereby performing lightning protection work; before it rains, the staff can simultaneously rotate the two rotating plates 55 in the rainwater collection device 5, thereby driving the two threaded rods 54 to rotate at the same time, the two screw rods 225 are threadedly connected to the connecting box 51, and the two screw rods 225 are bearing-connected to the closing plate 56, so the two threaded rods 54 drive the closing plate 56 to descend, the filter screen 52 is no longer closed, and the rainwater passes through the filter screen 52 into the connecting box 51 for storage. After it rains, the staff can reversely rotate the two rotating plates 55 to make the closing plate 56 rise, thereby closing the filter screen 52 to prevent the rainwater from evaporating and losing. When necessary, the staff can unscrew the threaded block 53 to release the rainwater, so as to better meet the work needs during cleaning and the like. The connecting column 4 serves to connect the shell 1 and the connecting box 51.
