[0002] Solid insulating materials are solid materials used to isolate conductors of different potentials. They are generally required to also provide support. Compared to gaseous and liquid insulating materials, solid insulating materials have a higher density and therefore a much higher breakdown strength, which is important for reducing insulation thickness.

[0021] In the specific implementation process, Figure 1 and Figure 2 As shown, a motor 53 is mounted on the upper right-angle plate, and the output end of the motor 53 is fixedly connected to the rotating shaft 51 at the upper end.

[0022] It should be noted that: the motor 53 controls the rotation of the upper end shaft 51, and the brush head 52 at the other end of the two shafts 51 can rotate accordingly, so as to automatically clean the two filters 43 to ensure good permeability of the filters 43 at the pipe openings of the air inlet pipe 4 and the air outlet pipe 41.

[0023] refer to Figure 1 and Figure 2 As shown, the two rotating shafts 51 are fixedly connected with transmission wheels 6 , and a transmission belt 61 is installed and connected between the two transmission wheels 6 .

[0024] It should be noted that the transmission wheels 6 on the two rotating shafts 51 are synchronously driven by the transmission belts 61 so that the brush heads 52 at the other ends of the two rotating shafts 51 can rotate accordingly.

[0025] refer to Figure 1 and Figure 3 As shown, a protective plate 7 is provided above the control button area 3 , and side ears 71 are provided at both ends of the protective plate 7 , and convex shafts are provided at both ends of the protective plate 7 , and the two convex shafts are rotatably connected to the two side ears 71 respectively.

[0026] It should be noted that the protective plate 7 is rotated and opened so as to rotate relative to the two side ears 71 , so that the protective plate 7 can be used to protect the control button area 3 .

[0027] refer to Figure 3 As shown, a groove is provided on the operating table of the host 1, in which a main magnetic block 8 is installed and connected. An embedded groove is provided on the protective plate 7, in which a secondary magnetic block 81 is installed and connected. The magnetic poles of the main magnetic block 8 and the secondary magnetic block 81 are opposite.

[0028] It should be noted that the secondary magnetic block 81 on the protective plate 7 abuts against the main magnetic block 8 , and the protective plate 7 can be locked in place by utilizing magnetic force.

[0031] The working principle of the insulation breakdown test device provided by the present invention is as follows: when operation is required, the protective plate 7 is rotated and opened so that it rotates relative to the two side ears 71, so that the secondary magnetic block 81 on the protective plate 7 is separated from the main magnetic block 8, so that the control button area 3 can be operated normally. The protective plate 7 can protect the control button area 3 to prevent it from being touched.
