At this time, the inner wall of the sealing block 603 will be in close contact with the surface of the external connecting wire, so that the external connecting wire can be sealed with the tapping box body 1. Then, external calcium chloride desiccant is added into the drying box 10, and the fan 2 is controlled to rotate. When the fan 2 rotates, the air outside the tapping box body 1 can be sucked into the limiting box 5, and the dust in the air is filtered through the filter element 15, and then enters the drying box 10. The humidity in the air is removed by the calcium chloride desiccant, and then the dry air will enter the tapping box body 1, so that the dry air circulates inside the tapping box body 1, keeping the inside of the tapping box body 1 dry, and effectively dissipating heat from the components inside the tapping box body 1, avoiding the problems that most of the existing intensive busbar tapping boxes have poor sealing effects, dust in the environment easily enters the inside of the tapping box and adheres to the surface of the components inside the tapping box, which easily leads to poor contact, and when the environmental humidity is high, the environmental humidity easily invades the inside of the tapping box, and over time, it easily causes corrosion of the metal components inside the tapping box and poses a safety hazard.

[0032] As a technical optimization scheme of the utility model, a filter element 15 is movably inserted into the limiting box 5, and a first screen 14 is embedded on the rear side of the limiting box 5.

[0034] As a technical optimization scheme of the utility model, clamping blocks 11 are fixedly connected to both sides of the filter element 15, limiting blocks 16 are fixedly connected to the front side and the rear side of the opposite sides of the two clamping blocks 11, limiting holes 17 are formed in the front side and the rear side of both sides of the limiting box 5, and the surface of the limiting block 16 is in contact with the inner wall of the limiting hole 17.

[0035] In this embodiment: By inserting the filter element 15 into the limiting box 5, the limiting block 16 is clamped into the limiting hole 17, so that the filter element 15 can be limited, achieving the effect of connecting the filter element 15 with the limiting box 5.

[0036] As a technical optimization scheme of the utility model, the clamping block 11 is made of corrosion-resistant elastic plastic, and a pull ring 18 is fixedly connected to the surface of the clamping block 11.

[0037] In this embodiment: Since the clamping block 11 is made of corrosion-resistant elastic plastic, the clamping block 11 can be deformed, facilitating the movement of the limiting block 16 into the limiting hole 17, achieving the effect that the clamping block 11 can be deformed.

[0038] As a technical optimization scheme of the present utility model, a second screen 13 is fixedly connected to the rear side of the inner wall of the drying box 10.

[0039] In this embodiment: By inlaying the second screen 13 on the rear side of the inner wall of the drying box 10, the externally connected calcium chloride desiccant inside the drying box 10 can enter the limiting box 5, achieving the effect of preventing the externally connected calcium chloride desiccant from entering the limiting box 5.

[0040] As a technical optimization scheme of the present utility model, sealing covers 12 are provided at both the top and bottom of the drying box 10, and the surface of the sealing cover 12 is threadedly connected to the inside of the drying box 10.

[0041] In this embodiment: Through the threaded connection between the sealing cover 12 and the inside of the drying box 10, when the sealing cover 12 rotates, the sealing cover 12 can be moved. Turning the top sealing cover 12 away from the drying box 10 allows the externally connected calcium chloride desiccant to be added into the drying box 10. Turning the bottom sealing cover 12 away from the drying box 10 allows the externally connected calcium chloride desiccant inside the drying box 10 to be discharged and replaced, achieving the effect of facilitating the addition and discharge of the externally connected calcium chloride desiccant into and out of the drying box 10.

[0042] As a technical optimization scheme of the present utility model, a third screen 19 is inlaid on the rear side of the tap-off box 1, and the front side of the drying box 10 is communicated with the second screen 13.

[0043] In this embodiment: By blocking the externally connected calcium chloride desiccant inside the drying box 10 through the third screen 19, the externally connected calcium chloride desiccant can be prevented from entering the tap-off box 1, achieving the effect of preventing the externally connected calcium chloride desiccant from entering the tap-off box 1.

[0044] As a technical optimization scheme of the present utility model, two fans 2 are inlaid on the front side of the tap-off box 1.

[0045] In this embodiment: By controlling the operation of the fans 2, the fans 2 can generate suction when operating, sucking the external air into the limiting box 5, the drying box 10, and the tap-off box 1, achieving the effect of facilitating the suction of the external air into the tap-off box 1.

[0046] As a technical optimization scheme of the present utility model, mounting blocks 7 are fixedly connected to the surface of the tap-off box 1, and the number of the mounting blocks 7 is several and they are evenly distributed on the surface of the tap-off box 1.

[0047] In this embodiment: By using an external bolt to pass through the mounting block 7 and thread-connecting the external bolt to the mounting position, the tap-changing box body 1 can be conveniently installed, achieving the effect of facilitating the installation of the tap-changing box body 1.

[0048] As a technical optimization solution of the present utility model, the material of the sealing block 603 is polytetrafluoroethylene.

[0049] In this embodiment: Since the material of the sealing block 603 is polytetrafluoroethylene and polytetrafluoroethylene has good weather resistance, the service life of the sealing block 603 can be extended, achieving the effect of extending the service life of the sealing block 603.

[0050] Working principle: First, pass an external bolt through the mounting block 7 and thread-connect the external bolt to the mounting position, so as to facilitate the installation of the tap-changing box body 1. After passing the external connecting wire through the fixing pipe 9 and extending it into the tap-changing box body 1 for connection, move the sealing block 603 until the inner wall of the sealing block 603 contacts the surface of the fixing pipe 9, and then move the pressing block 602 until the inner wall of the pressing block 602 contacts the surface of the sealing block 603. At this time, pass the screw 601 through the pressing block 602 and the sealing block 603 in sequence and thread-connect the screw 601 to the inside of the fixing pipe 9, so as to fix the sealing block 603. At this time, the inner wall of the sealing block 603 will be in close contact with the surface of the external connecting wire, so as to seal between the external connecting wire and the tap-changing box body 1. Then rotate the top sealing cover 12 to separate the top sealing cover 12 from the drying box 10, pour the external calcium chloride desiccant into the drying box 10, and then reset the top sealing cover 12. During the use of the tap-changing box body 1, control the fan 2 to rotate. When the fan 2 rotates, the air outside the tap-changing box body 1 can be sucked into the limiting box 5, and the dust in the air is filtered through the filter element 15, and then enters the drying box 10, and the humidity in the air is removed by the calcium chloride desiccant. Then the dry air will enter the tap-changing box body 1, so that the dry air circulates inside the tap-changing box body 1, keeping the inside of the tap-changing box body 1 dry, and effectively dissipating heat from the components inside the tap-changing box body 1, avoiding the problem that most of the existing tap-changing boxes of dense busbars have poor sealing effects, and the dust in the environment easily enters the inside of the tap-changing box and adheres to the surface of the components inside the tap-changing box, which easily leads to poor contact. And when the environmental humidity is high, the environmental humidity easily invades the inside of the tap-changing box, and over time, it easily causes the metal components inside the tap-changing box to rust and pose a safety hazard. It should be noted that the calcium chloride desiccant has a high moisture absorption efficiency. When the air passes through the dense calcium chloride desiccant particles, the calcium chloride desiccant particles can remove the moisture in the air. When the filter element 15 needs to be replaced, pull the pull ring 18 to deform the clamping block 11, so that the limiting block 16 is separated from the inside of the limiting hole 17, and then pull the filter element 15 upward to pull out the filter element 15 from the limiting box 5 for replacement. It should be noted that both the tap-changing box body 1 and the sealing box cover 4 are made of strong and good insulating materials, such as high-strength plastic or metal shell with insulation treatment. In terms of the internal structure, it includes plug-and-play interfaces for connecting busbars. These interfaces are designed precisely and have good conductivity and stability, which can ensure that live plug-and-play operations can be carried out while ensuring stable and safe current transmission.

[0051] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
