[0030] In the description of the present disclosure, it should be understood that the terms "upper", "lower" and the like indicate the orientation or positional relationship defined based on the normal use direction of the transformer box, and are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, and a particular orientation configuration and operation, and therefore cannot be understood as a limitation on the present disclosure, in addition, the terms "inner, outer" refer to the inner and outer of the corresponding structure profile. In addition, the terms "first", "second" and the like are only used to distinguish one element from another element, and do not have sequentiality and importance.

[0031] In the description of the present disclosure, it should also be noted that unless otherwise explicitly specified and limited, the terms "provided", "connected", "connected", "installed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0032] The present disclosure provides a transformer box in the first aspect to solve the technical problems existing in the related art.

[0033] As Figures 1 to 4As shown, the transformer box 10 provided by the present disclosure comprises a box body 100, an air cooling device 200 and a dehumidifying device 300. The box body 100 is used for accommodating the transformer 20, and the box body 100 is provided with an exhaust port 101. The air cooling device 200 is installed on the box body 100, and an air inlet of the air cooling device 200 is used for communicating with the outside atmosphere. The dehumidifying device 300 is installed on the box body 100 and comprises a dehumidifying box 310, an elastic support 320 and an alarm switch 330. The dehumidifying box 310 is formed with a dehumidifying inlet 311 and a dehumidifying outlet 312, and is filled with a dehumidifying agent 313. The dehumidifying inlet 311 communicates with an air outlet of the air cooling device 200, and the dehumidifying outlet 312 communicates with the inside of the box body 100. The elastic support 320 is supported at the bottom of the dehumidifying box 310 and can be stretched and contracted in the up-down direction. The alarm switch 330 is arranged at the bottom of the dehumidifying box 310 in a spaced manner and can contact the dehumidifying box 310 after the dehumidifying box 310 moves downward by a set distance.

[0034] Through the above technical solution, the air cooled by the air cooling device 200 enters the dehumidifying box 310 through the dehumidifying inlet 311, and the moisture in the air is adsorbed by the dehumidifying agent 313 inside the dehumidifying box 310. The dry air leaves the dehumidifying box 310 through the dehumidifying outlet 312 and enters the box body 100, and the hot air is discharged from the exhaust port 101 of the box body 100 to the outside of the box body 100, thereby achieving heat dissipation and cooling of the transformer 20 in the box body 100. The weight of the dehumidifying agent 313 gradually increases in the process of absorbing moisture, so that the weight of the dehumidifying box 310 gradually increases, thereby overcoming the elastic force of the elastic support 320 and making the dehumidifying box 310 gradually move downward. After the dehumidifying box 310 moves by a set distance, the dehumidifying box 310 contacts the alarm switch 330, so that the alarm switch 330 is triggered and the above alarm information is reported. The alarm switch 330 can be electrically connected with an alarm, a display screen or a loudspeaker in a monitoring room, so that relevant personnel can receive the warning information after the alarm switch 330 is triggered, thereby knowing that the dehumidifying box 310 of the transformer box 10 has reached a set saturation threshold and needs to be replaced, so as to actively replace the dehumidifying box 310, thereby ensuring that the dehumidifying box 310 can always adsorb the moisture in the air provided by the air cooling device 200.

[0035] It should be noted that the alarm switch 330 can be in communication connection with the above-mentioned alarm, display screen or loudspeaker through wireless transmission, or can be in communication connection with the above-mentioned alarm, display screen or loudspeaker through a cable, and the present disclosure does not make specific limitations thereon. The alarm, display screen or loudspeaker can be arranged in a specific monitoring room, for example, a monitoring room in a thermal power plant. The maximum water absorption amount of the dehumidifier 313 in the dehumidifying box 310 corresponds to the maximum moving distance of the dehumidifying box 310, and when setting the set distance of the dehumidifying box 310 moving downward, the set distance can be set to be less than the above-mentioned maximum moving distance, so as to leave a dehumidification margin for the dehumidifying box 310, thereby reserving time for the process of the operating personnel receiving the alarm signal to the replacement of the dehumidifying box 310, and ensuring that the air inside the transformer tank 10 can be kept dry at all times.

[0036] In addition, the above-mentioned air cooling device 200 can cool the air by using a semiconductor refrigeration sheet, can cool the air by using an air cooler, or can cool the air by using a matched compressor, condenser and evaporator, and the present disclosure does not make specific limitations thereon.

[0038] In some optional embodiments, as shown in Figure 3 The dehumidifying device 300 further includes a dehumidifying box 340 and a flexible pipe 350, the dehumidifying box 340 is installed on the tank body 100, the dehumidifying box 340 has a containing cavity therein, the dehumidifying box 310, the elastic support 320, the alarm switch 330 and the flexible pipe 350 are located in the containing cavity, the dehumidifying box 340 is provided with an air inlet 341 and an air outlet 342, the air inlet 341 is in communication with the air outlet of the air cooling device 200, the air outlet 342 is in communication with the inside of the tank body 100, the first end of the flexible pipe 350 is connected with the air inlet 341, the second end of the flexible pipe 350 is detachably connected with the dehumidifying inlet 311, the dehumidifying outlet 312 and the air outlet 342 are both in communication with the containing cavity, and the air outlet 342 is configured to enable the dehumidifying box 310 to enter or exit the containing cavity from the air outlet 342.

[0039] The dehumidification box 310, the elastic support 320, the alarm switch 330 and the flexible pipe 350 are arranged in the dehumidification box 340, which can play a certain protective role, avoiding the dehumidification box 310, the elastic support 320, the alarm switch 330 and the flexible pipe 350 from being directly exposed to the environment and accidentally damaged. At the same time, by arranging the flexible pipe 350 in a detachable manner at one end connected with the air inlet 341 and the other end connected with the dehumidification inlet 311, the flexible pipe 350 can adapt to the movement of the dehumidification box 310 and always keep connected with the dehumidification box 310 during the movement of the dehumidification box 310 after absorbing moisture. At the same time, when replacing the dehumidification box 310, the flexible pipe 350 also makes the dehumidification box 310 convenient to be taken out from the air outlet 342 for replacement or installation.

[0040] The detachable connection mode of the flexible pipe 350 and the dehumidification box 310 includes but is not limited to clamp connection, buckle connection and magnetic attraction connection, and the present disclosure does not make specific limitation.

[0042] In some optional embodiments, as shown in Figures 1-3 The dehumidification box 340 is installed on the outer surface of the box body 100, and the air inlet 102 is formed on the box body 100 and is in butt joint with the air outlet 342, and the air inlet 102 is configured to allow the dehumidification box 310 to pass through. Installing the dehumidification box 340 on the outer surface of the box body 100 does not occupy the internal space of the box body 100. Moreover, the air inlet 102 formed on the box body 100 is in butt joint with the air outlet 342, so that the operator must open the box body 100 to complete the replacement of the dehumidification box 310 through the air inlet 102 and the air outlet 342. Therefore, only the operator can complete the replacement of the dehumidification box 310, avoiding unauthorized personnel from dismounting the dehumidification box 310.

[0043] Optionally, the air outlet 342 of the dehumidification box 340 is set on the side of one side of the dehumidification box 340, and after the dehumidification box 340 is installed on the outer surface of the box body 100, the side of the dehumidification box 340 on which the air outlet 342 is set is in contact with the box body 100, thereby further preventing the dehumidification box 310 from being taken out from outside the box body 100.

[0044] In some optional embodiments, the box body 100 includes a box door 120 and a box body 110, the dehumidification box 340 is mounted on the outer surface of the box door 120, and the air inlet 102 is formed on the box door 120. The dehumidification box 340 is arranged on the box door 120, and the operator can complete the replacement of the dehumidification box 310 inside the dehumidification box 340 by opening the box door 120, which has a large operating space and is more convenient for replacement.

[0045] It should be noted that the exhaust port 101 is provided on the box body 110 , and the air cooling device 200 is provided on the box door 120 , so as to increase the path of air circulation inside the main box body 100 and improve the cooling effect inside the box body 100 .
