[0031] The usage method of the present utility model is as follows:

[0032] Since the upper shell 101, the lower shell 102, the upper observation window 3, and the lower observation window 5 are all made of transparent and environmentally friendly materials, the staff can directly observe the situation inside the insulating shell through the upper shell 101, the lower shell 102, the upper observation window 3, or the lower observation window 5, and timely judge whether the inside of the insulating shell is affected by discharge, so as to be able to replace the insulating shell in time before it completely fails, effectively avoiding the situation that the insulating shell is damaged or perforated during use, which may cause accidents, effectively eliminating potential safety hazards. Moreover, the existence of the upper observation window 3 can effectively increase the actual volume of the upper shell, and the existence of the lower observation window 5 can effectively increase the actual volume of the lower shell, thereby effectively increasing the internal space of the insulating shell. As the space becomes larger, the heat inside the insulating shell will be reduced accordingly, thus avoiding the situation of breakdown discharge caused by the heat generation always being greater than the heat dissipation, further eliminating potential safety hazards.

[0033] The upper shell 101, the lower shell 102, the upper observation window 3, and the lower observation window 5 are all made of glass materials, and the glass materials can be recycled, which conforms to the environmental protection characteristics.

[0034] The easy disassembly and assembly structure includes an upper limiting part 6 provided on the outer wall of the lower end of the upper shell 101 and a lower limiting part 7 provided on the outer wall of the upper end of the lower shell 102. The lower surface of the upper limiting part 6 fits with the upper surface of the lower limiting part 7. An annular hidden groove 8 is provided on the upper surface of the upper limiting part 6, and a number of uniformly distributed first screw holes 9 are provided on the upper surface of the lower limiting part 7. A number of first through holes 10 that communicate with the first screw holes 9 are provided at the bottom of the hidden groove 8. A first screw 11 passes downward through the first through hole 10 and is screwed into the first screw hole 9. The head of the first screw 11 fits with the bottom of the hidden groove 8. This fixing method facilitates the disassembly and assembly of the upper shell 101 and the lower shell 102. Just by unscrewing the first screw 11, the separation between the upper shell 101 and the lower shell 102 can be achieved, which is beneficial to the maintenance and replacement of the internal components of the insulating shell.

[0035] An auxiliary cover 12 that matches the upper notch of the hidden slot 8 is provided inside the upper notch. The auxiliary cover 12 is made of rubber. The lower surface of the auxiliary cover 12 fits with the upper surface of the head of the first screw 11. A middle insulating cover 13 made of rubber covers the upper limiting part 6 and the lower limiting part 7. The existence of the auxiliary cover 12 and the middle insulating cover 13 can effectively prevent the electric arc inside the insulating shell from leaking to the outside through the gap between the lower surface of the upper limiting part 6 and the upper surface of the lower limiting part 7, effectively ensuring the insulating effect.

[0036] The lower port of the upper shell 101 is provided with an annular upper limiting notch 14, and the upper port of the lower shell 102 is provided with an annular lower limiting notch 15. An annular insulating pad 16 is provided between the inner wall on the upper side of the upper limiting notch 14 and the inner wall on the lower side of the lower limiting notch 15. An annular upper insulating part 17 extends upward from the inner edge of the upper surface of the insulating pad 16, and the outer wall of the upper insulating part 17 fits with the inner wall of the lower port of the upper shell 101. An annular lower insulating part 18 extends downward from the inner edge of the lower surface of the insulating pad 16, and the outer wall of the lower insulating part 18 fits with the inner wall of the upper port of the lower shell 102. The existence of the insulating pad 16, the upper insulating part 17, and the lower insulating part 18 can further prevent the electric arc inside the insulating shell from leaking to the outside through the gap between the lower surface of the upper limiting part 6 and the upper surface of the lower limiting part 7, further ensuring the insulating effect when the upper shell 101 and the lower shell 102 are connected and fixed.

[0037] The existence of the upper screw 32 can effectively ensure the stability between the upper observation window 3 and the upper U-shaped guiding platform 19. If there is a problem with the components in the upper space of the insulating shell body 1, the maintenance work can be carried out by removing the upper observation window 3 without directly disassembling the upper shell 101, reducing a lot of trouble. When the upper observation window 3 needs to be removed, only need to unscrew the upper screw 32 from the upper screw hole 23. At this time, the components in the upper space of the insulating shell can be repaired through the upper window 2.

[0038] The existence of the lower screw 27 can effectively ensure the stability between the lower observation window 5 and the lower U-shaped guiding platform 20. If there is a problem with the components in the lower space of the insulating shell body 1, the maintenance work can be carried out by removing the lower observation window 5 without directly disassembling the lower shell 102, reducing a lot of trouble. When the lower observation window 5 needs to be removed, only need to unscrew the lower screw 27 from the lower screw hole 25. At this time, the components in the lower space of the insulating shell can be repaired through the lower window 4.

[0039] At the same time, the first screw 11, the upper screw 32, and the lower screw 27 can all adopt insulating screws, effectively ensuring the insulating effect of the insulating shell.

[0040] The outer walls on the front and rear sides of the upper U-shaped guiding platform 19 and the lower U-shaped guiding platform 20 are provided with symmetric guiding chutes 28. The inner walls on the front and rear sides of the upper observation window 3 and the lower observation window 5 are both provided with guiding strips 29 that match the guiding chutes 28. The existence of the guiding strips 29 can not only play a guiding role when the upper observation window 3 and the lower observation window 5 slide, but also play a positioning role when the upper observation window 3 and the lower observation window 5 are assembled, ensuring that both the upper observation window 3 and the lower observation window 5 can be closely attached to the outer wall of the insulating shell.

[0041] A main insulating cover 30 made of rubber is covered outside both the upper observation window 3 and the lower observation window 5. The main insulating cover 30 can play an auxiliary insulating effect, further ensuring the insulating effect of the upper observation window 3 and the lower observation window 5.

[0042] One end of the outer wall of the main insulating cover 30 that is in contact with the outer wall of the insulating shell body 1 extends outward to form an extension part 31. The extension part 31 is in contact with the outer wall of the insulating shell body 1. The existence of the extension part 31 can effectively increase the contact area between the main insulating cover 30 and the outer wall of the insulating shell body 1, thereby effectively increasing the insulating area and ensuring the insulating effect of the upper observation window 3 and the lower observation window 5 to the greatest extent.
