Inside the display body 1, there are a voltage sensor 19, a partial discharge detector 22, and a temperature detector 23 that are all electrically connected to the wiring terminal 14. On the front end 101 surface of the display body 1, there are indicator lights 3, a phase-checking hole 21, and a display screen 4.

On the outer wall of the installation frame 2, there is a temperature and humidity detection sensor 20 that is electrically connected to the control module. The temperature and humidity detection sensor 20 can be arranged at any position on the outer wall of the installation frame 2 according to the actual situation. By setting the voltage sensor 19, the partial discharge detector 22, the temperature detector 23, the indicator lights 3, the phase-checking hole 21, and the display screen 4, and the phase-checking hole 21 and the indicator lights 3 are both electrically connected to the voltage sensor 19, the phase-checking hole 21 is convenient for connecting special equipment to check the high-voltage phase sequence. When the voltage sensor 19 detects that the equipment is live, the indicator lights 3 emit flashes, which can warn people that the high-voltage equipment is live, thus playing a warning role. The voltage sensor 19, the partial discharge detector 22, and the temperature detector 23 are all electrically connected to the wiring terminal 14. The voltage sensor 19 is used to detect voltage, the partial discharge detector 22 is used to detect partial discharge, and the temperature detector 23 is used to detect the temperature of the high-voltage cable head at the wiring terminal 14. On the outer wall of the installation frame 2, there is a temperature and humidity detection sensor 20 that is electrically connected to the control module. The temperature and humidity detection sensor 20 is used to detect the temperature and humidity inside the ring main unit. At the same time, the voltage sensor 19, the partial discharge detector 22, the temperature detector 23, and the temperature and humidity detection sensor 20 are all electrically connected to the display screen 4 through the control module. The display screen 4 can display the indexes detected by the voltage sensor 19, the partial discharge detector 22, the temperature detector 23, and the temperature and humidity detection sensor 20.

[0023] Embodiment 2:
[0024] Refer to Figures 1 to 5It is shown that an installation groove 5 for connecting the rear end 102 of the display body 1 is provided in the installation frame 2. Connecting grooves 6 are provided on the groove walls on the upper and lower sides of the installation groove 5. A resilient assembly is provided in the connecting groove 6. The resilient assembly is connected with a hemispherical protrusion 7 for fixing the display body 1. Grooves 8 matching the protrusions 7 are provided on the top and bottom of the rear end 102 of the display body 1. During actual use, by providing the resilient assembly and the protrusions 7, when the display body 1 needs to be installed, the rear end 102 of the display body 1 is pushed into the installation groove 5 through the notch of the installation groove 5, so that the top and bottom of the rear end 102 of the display body 1 press the protrusions 7 to retract into the connecting groove 6, thereby squeezing the resilient assembly in the connecting groove 6 until the rear end 102 of the display body 1 is completely placed in the installation groove 5. At this time, the grooves 8 on the top and bottom of the rear end 102 of the display body 1 face the protrusions 7 thereof. Under the action of the resilient assembly, the protrusions 7 are placed in the grooves 8, thereby realizing the fixation of the display body 1. When disassembly is required for maintenance, just pinch the front end 101 of the display body 1 and pull it outwards, so that the top and bottom of the display body 1 press the protrusions 7 to make them slide into the connecting groove 6, and the fixation of the display body 1 can be cancelled, and then the display body 1 can be disassembled for replacement and maintenance, increasing the work efficiency.
[0025] Refer to Figure 4 、 Figure 5 It is shown that the resilient assembly includes a support spring 9 and a limit ring 10. One end of the support spring 9 provided in the connecting groove 6 is connected to the bottom of the connecting groove 6, and the other end is connected with a limit block 11 movably provided in the connecting groove 6. The limit ring 10 is provided at the notch of the connecting groove 6. One end of the protrusion 7 penetrates through the limit ring 10 and is connected to the limit block 11, and the other end is placed in the installation groove 5. By providing the support spring 9, when the protrusion 7 is squeezed and slides into the connecting groove 6, the support spring 9 is squeezed. When the groove 8 faces the protrusion 7, the elastic potential energy existing in the support spring 9 pushes out the protrusion 7, so that the protrusion 7 is placed in the groove 8 to press the display body 1, thereby fixing the display body 1. The limit block 11 and the limit ring 10 are provided to play a limiting role on the protrusion 7 to prevent it from completely sliding out of the connecting groove 6.
[0026] Refer to Figure 4 、 Figure 5It is shown that two bumps 7 are movably connected to both the top and bottom of the display body 1. Guide posts 12 are installed between the two bumps 7 at the top and bottom of the display body 1, and one end of the guide post 12 faces the inside of the installation groove 5; sliding grooves 13 adapted to the guide posts 12 are provided on the groove walls on the upper and lower sides of the installation groove 5. The lengths of the guide posts 12 and the sliding grooves 13 are equal, so that when the guide posts 12 are completely placed in the sliding grooves 13, the bumps 7 are aligned with the grooves 8. By providing the guide posts 12 and the sliding grooves 13, when installing the display body 1, the ends of the guide posts 12 facing the installation groove 5 are respectively aligned with the sliding grooves 13, and then the display body 1 is pushed into the installation groove 5. The guide posts 12 and the sliding grooves 13 can play a guiding role, and thus when the display body 1 is installed in the installation groove 5, the bumps 7 are aligned with the grooves 8, and then it is ensured that the bumps 7 are smoothly placed in the grooves 8 to fix the display body 1.
[0027] Refer to Figure 5 It is shown that the inner ring diameter of the limit ring 10 is smaller than the outer ring diameter of the limit block 11, which can prevent the limit block 11 from completely sliding out of the connection groove 6 under the action of the support spring 9. The outer ring diameter of the bump 7 is smaller than the inner ring diameter of the limit ring 10, so as to ensure that the bump 7 can smoothly slide through the limit ring 10 and then slide into or out of the connection groove 6.
[0028] Refer to Figure 1 It is shown that a plurality of heat dissipation holes 16 communicating with the installation groove 5 are provided on the side wall of the installation frame 2, and a wire passing hole 15 communicating with the installation groove 5 is provided on the back of the installation frame 2. Providing the heat dissipation holes 16 is beneficial to the heat inside the installation groove 5 to dissipate, achieving a heat dissipation effect. By providing the wire passing hole 15, the situation where the power cord is pressed and damaged is avoided.
[0029] Refer to Figure 1 It is shown that connection blocks 17 are provided at both ends of the installation frame 2, and fixing holes 18 penetrating through both sides thereof are provided on the connection blocks 17. By providing the connection blocks 17 and the fixing holes 18, it is convenient to install the installation frame 2 in the area to be installed in the high-voltage ring main unit, and thus it is convenient to install the display body 1 in this area.
