[0030] See also Figure 1-Figure 7 , this utility model provides an environmentally friendly fully insulated and fully sealed switch cabinet technical solution:

[0031] Embodiment 1: In order to solve the problem in the prior art that when the cabinet door 2 is slightly loose, such a sealing method will easily have gaps, thereby resulting in a poor sealing effect, the following scheme is disclosed, including a cabinet 1, and the cabinet door 2 is hinged on the front side of the cabinet 1; it also includes: a sealing strip 3 is bonded to the rear side of the cabinet door 2, and the sealing strip 3 fits with the docking plate 4, and the docking plate 4 is fixed inside the cabinet 1; an arc-shaped sealing ring 5 is bonded to the inside of the docking plate 4, and the arc-shaped sealing ring 5 is provided in four groups, and the four groups of arc-shaped sealing rings 5 ​​are tightly fitted with the sealing strip 3; an inner insulating pad 6 is bonded to the inner wall of the cabinet 1, and the inner insulating pad 6 is made of insulating glue, and outer insulating plates 7 are provided on both sides of the cabinet 1;

[0032] First, the cabinet door 2 is hinged on the front side of the cabinet body 1, and the inner side of the cabinet door 2 is bonded with a sealing strip 3. When the cabinet door 2 is closed, it will drive the sealing strip 3 to fit with the docking plate 4, thereby achieving a sealing effect. When the sealing strip 3 fits with the docking plate 4, it will also contact the arc-shaped sealing ring 5. The tight connection between the arc-shaped sealing ring 5 and the sealing strip 3 further enhances the sealing effect. The sealing strip 3 fits with the docking plate 4 in a plug-in manner, so that when the cabinet door 2 is slightly loose, it will not affect the sealing effect. The inner wall of the cabinet body 1 is bonded There is an inner insulating pad 6, so that when there is internal leakage, the power will not be transmitted to the outside of the cabinet 1. By changing the traditional SF6 gas insulation to solid material insulation, it is beneficial to environmental protection. The inner insulating pad 6 uses a modified micro-nano filler with high density and high thermal conductivity to improve the electrical properties and heat dissipation properties of the solid insulating medium, thereby achieving the insulation effect. Graphene semiconductor paint is sprayed on the solid insulation surface of the inner insulating pad 6 to achieve grounding of the insulation surface of the primary circuit of the switch cabinet, which is highly safe and the primary main circuit is fully sealed, meeting the operation of high humidity, high pollution, high altitude and other full working conditions;

[0033] Embodiment 2: Different from Embodiment 1, this embodiment solves the problem that the outer insulating plate 7 is worn and inconvenient to replace, and the replacement process is time-saving and labor-saving. For details, refer to Figure 3 and Figure 5 , a clamping rod 8 is fixed on both sides of the cabinet 1, and the outer end of the clamping rod 8 is fixed to the clamping ball 9, and the clamping ball 9 is made of rubber material, and the clamping ball 9 is connected to the outer insulating plate 7 in a clamping manner, and the clamping rod 8 is provided with two groups, and each group of the clamping rods 8 is provided with three;

[0034] In addition, outer insulating plates 7 are installed on both sides of the cabinet 1, and the outer insulating plates 7 are made of the same material and manufacturing process as the above-mentioned inner insulating pads 6, thereby further improving the insulation effect. When the outer insulating plates 7 are worn or the insulation effect is reduced, it is only necessary to pull the outer insulating plates 7 outward to disengage the outer insulating plates 7 from the clamping rods 8 and the clamping balls 9, thereby releasing the position limit of the outer insulating plates 7, and then docking the new outer insulating plates 7 with the clamping rods 8 and the clamping balls 9, and the position limit of the outer insulating plates 7 is achieved by the clamping balls 9, thereby solving the problem that the outer insulating plates 7 are worn and inconvenient to replace, and the replacement process is time-saving and labor-saving;

[0035] Embodiment 3: Different from Embodiment 2, the spacing between the mounting plates 12 can be adjusted according to actual use requirements. Figure 3-Figure 4A guide rail 10 is fixed inside the cabinet 1, and two groups of guide rails 10 are provided, and inclined blocks 11 are fixed inside the guide rail 10 at equal intervals, the lower surface of the inclined block 11 is an inclined structure, and an adjusting block 14 is provided above the inclined block 11, and the upper surface of the adjusting block 14 is an inclined structure, and the inclined block 11 is used to support the adjusting block 14, and a connecting slider 13 is slidably connected inside the guide rail 10, and the adjusting block 14 is slidably connected with the connecting slider 13 through a reset spring 15, and the two ends of the reset spring 15 are respectively fixed to the connecting slider 13 and the adjusting block 14, the inner side of the adjusting block 14 is fixed to a pull rope 16, and the other end of the pull rope 16 is fixed to a push rod 17, and the lower end of the push rod 17 passes through the lower surface of the mounting plate 12, and a sliding connection is formed between the push rod 17 and the mounting plate 12, the inner end of the connecting slider 13 is fixed to the mounting plate 12, and the mounting plate 12 is provided with six groups;

[0036] In addition, a mounting plate 12 is provided inside the cabinet 1, and the mounting plate 12 is provided to facilitate installation of the switch. The mounting plate 12 is lifted upward, thereby driving the connecting slider 13 to slide upward in the guide rail 10, and then the connecting slider 13 drives the adjusting block 14 to contact the inclined block 11, so that the adjusting block 14 is forced to slide inward, so that the mounting plate 12 can move upward. When the adjusting block 14 is no longer limited by the inclined block 11, the elastic force of the reset spring 15 drives the adjusting block 14 to reset. Thereby, the adjusting block 14 is engaged with the inclined block 11, thereby realizing the height adjustment of the mounting plate 12. When the mounting plate 12 needs to be moved downward, the push rod 17 only needs to be pushed inward, so that the push rod 17 pulls the adjusting block 14 to slide inward through the pull rope 16, so that the adjusting block 14 is no longer engaged with the inclined block 11, and then the mounting plate 12 can be bent downward as a whole, so that the distance between the mounting plates 12 can be adjusted according to actual usage requirements, and it is also more convenient during maintenance.
