[0008] By adopting the above technical solution, the signal of the DTU terminal device passes through the first wire, the antenna box, the second wire, and the antenna connector, and is transmitted to the antenna body connected to the antenna connector, and the signal is sent out through the antenna body; conversely, the antenna body receives the signal and then transmits the signal to the DTU terminal device. This ensures that signal transmission is no longer physically blocked by the box or cabinet, and is no longer affected by electromagnetic interference from high-voltage equipment. This makes the signal transmission of the DTU terminal device stable, allowing staff to smoothly remotely control the high-voltage equipment.

[0009] Optionally, a mounting plate is provided on the inner wall of the box body close to the operation hole, and bolts are provided between the antenna box and the mounting plate to connect the two.

[0010] By adopting the above technical solution, the mounting plate supports the antenna box, so that the antenna box is not easily hung in the air; the bolt connection method is adopted, which facilitates the disassembly and assembly of the antenna box and the mounting plate.

[0018] By adopting the above technical solution, in rainy weather, rainwater falls on the roof and flows along the inclined surface of the guide slope, making it difficult for rainwater to accumulate on the roof, thereby reducing the chance of roof corrosion.

[0019] Optionally, the top cover extends outside the box along the length direction of the box body, and the antenna connector is located directly below the top cover.

[0020] By adopting the above technical solution, when the antenna body is installed on the antenna connector, the top cover can shield the antenna body from rain and protect the antenna body.

[0021] Optionally, the accommodating cavity passes through the box body upwards, and a fixing groove is provided on the bottom wall of the top cover, a part of the fixing groove is communicated with the accommodating cavity, and another part of the fixing groove is communicated with the outside.

[0022] By adopting the above technical solution, when the switchgear is working, the temperature inside the box rises, and the hot air in the box is exchanged with the outside world through the fixed groove, thereby improving the heat dissipation performance of the switchgear.

[0023] Optionally, the upper end surface of the box body is provided with a wire frame located in a fixing groove, and the lower end surface of the wire frame is provided with a through hole communicating with the outside.

[0024] By adopting the above technical solution, the wires can be stored in the wire frame through the wire frame, thereby playing a storage role.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The signal from the DTU terminal device passes through the first wire, antenna box, second wire, antenna connector, and is transmitted to the antenna body connected to the antenna connector, and the signal is sent out through the antenna body. Conversely, the antenna body receives the signal and then transmits the signal to the DTU terminal device. This ensures that signal transmission is no longer physically blocked by boxes or cabinets, and is no longer affected by electromagnetic interference from high-voltage equipment. This ensures stable signal transmission from the DTU terminal device, allowing staff to remotely control high-voltage equipment smoothly.

[0027] 2. LED lights provide lighting effects, allowing workers to perform maintenance work in a bright environment. BRIEF DESCRIPTION OF THE DRAWINGS
