Description

[0002] The high-voltage switch operating mechanism is a key device used to control and operate high-voltage switchgear in power systems. Its main function is to achieve the closing, disconnection, connection or isolation of power equipment. The high-voltage switch operating mechanism usually provides the necessary mechanical power through electric or pneumatic means to ensure the normal operation of the switch. Its design requires high reliability and durability to cope with frequent operations and complex working environments in power systems. Common high-voltage switch operating mechanisms include pneumatic, hydraulic, electric, etc. These mechanisms convert operating signals into switch movements through precise mechanical transmission systems to ensure the stable realization of electrical isolation and on-off functions.

[0003] In practical applications, the selection of high-voltage switch operating mechanisms is usually based on factors such as the type of switchgear, operating frequency, and environmental conditions. For example, pneumatic operating mechanisms are often used to operate high-voltage disconnectors and load switches because of their fast response speed and reliable operation, while hydraulic operating mechanisms are suitable for equipment that requires greater operating force. Electric operating mechanisms are widely used in systems with a high degree of automation and can achieve remote control and automated operation through electrical signals. All of these operating mechanisms must ensure insulation performance and mechanical stability in high voltage and high current environments to prevent the impact on the power grid system due to failures or improper operation.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0030] The first implementation method:

[0031] See also Figure 1-7 A highly protective high-voltage switch operating mechanism box comprises a mechanism box body 1, a load-bearing bottom plate 2 is fixedly connected to the lower end of the mechanism box body 1, a plurality of heat dissipation holes 3 are provided at both ends of the mechanism box body 1, a high-voltage switch operating mechanism body 4 is provided in the mechanism box body 1, and the high-voltage switch operating mechanism body 4 is located at the upper end of the load-bearing bottom plate 2, a mounting groove is provided at the upper end of the load-bearing bottom plate 2, a water seepage box 5 is fixedly connected to the inner wall of the mounting groove, the water seepage box 5 is filled with a composite dehumidifier, an inner frame 6 is fixedly connected to the end of the water seepage box 5 away from the high-voltage switch operating mechanism body 4, and the inner frame 6 is located in the mounting groove, and an inner frame 6 is fixedly connected to the inner wall of the mounting groove. The outer frame 8 is fixedly connected to the outer frame 8, and the outer shape-changing bag 9 is connected to the inner shape-changing bag 7. Water enters the mechanism box 1 and penetrates into the water seepage box 5, so that the composite dehumidifier absorbs the moisture and releases a large amount of gas, thereby allowing the gas to enter the inner frame 6 and the outer shape-changing bag 9, so that the gas expands upward and stands upright to cover and seal the gap between the mechanism box 1 and the box door and the gap between the load-bearing bottom plate 2 and the box door, thereby preventing rainwater from continuing to penetrate and protecting the high-voltage switch operating mechanism body 4.

[0032] The seepage box 5 includes a first loading box 51, which is fixedly connected to the inner wall of the installation groove, and the composite dehumidifier is filled in the first loading box 51. A pair of first one-way valves 52 are fixedly connected to the upper end of the first loading box 51, and a first screw cover 53 is threadedly connected to the upper end of the first loading box 51, and the first screw cover 53 is located between the pair of first one-way valves 52. Rainwater penetrates into the first loading box 51 from the first one-way valve 52 and contacts with the composite dehumidifier, which not only absorbs water but also reacts to produce gas. Under the action of the first one-way valve 52, the gas is not easy to flow out, so that the gas can only enter the inner deformation bag 7 and the outer frame 8. Twisting the first screw cover 53 can facilitate the addition of the composite dehumidifier and prevent the gas from leaking.

[0033] The inner walls of the inner deformation capsule 7 and the outer deformation capsule 9 are coated with a high-temperature resistant coating, and the high-temperature resistant coating is made of silicone material. The outer ends of the inner deformation capsule 7 and the outer deformation capsule 9 are wrapped with softening glue, and the softening glue is made of polyvinyl alcohol material. The high-temperature resistant coating can prevent the high temperature of the generated gas from causing damage to the inner deformation capsule 7. The silicone resin material has excellent high-temperature stability, can withstand high temperatures of 250°C to 650°C, and has good antioxidant properties, so that the inner deformation capsule 7 can be used for a long time. The softening glue softens after encountering water and fills the gap, which can further play a sealing role and reduce the infiltration of rainwater. The polyvinyl alcohol material is a water-soluble polymer that can form a viscous solution in water and has good film-forming and hydrogel properties. It can absorb water and swell in water to form a softened gel-like structure, and can continue to be used after drying.

[0034] A spare box 11 is fixedly connected to the lower end of the first loading box 51, and the spare box 11 is located in the installation groove. The spare box 11 is filled with particles same as those of the composite dehumidifier. The spare box 11 is communicated with the inner deformation capsule 7. A reserved groove 10 is provided on the inner wall of the installation groove away from the inner frame 6. Rainwater seeps into the reserved groove 10 and enters the spare box 11, so that the composite dehumidifier in the spare box 11 absorbs water and reacts to release gas, causing the inner deformation capsule 7 and the outer deformation capsule 9 to further swell and expand to the limit, thereby blocking and sealing the gap between the entire box door and the mechanism box body 1 to prevent rainwater from submerging the entire mechanism box body 1 and causing damage to the high-voltage switch operating mechanism body 4.

[0035] The spare box 11 includes a second loading box 111, which is fixedly connected to the lower end of the first loading box 51. The second loading box 111 is fixedly connected to the end away from the inner frame 6 with a second one-way valve 112. The upper end of the second loading box 111 is fixedly connected to a guide tube 113, and the guide tube 113 is located on the side of the seepage box 5 away from the inner frame 6. The upper end of the guide tube 113 is threadedly connected with a second screw cover 114. The second screw cover 114 is opened by twisting to add the composite dehumidifier from the guide tube 113 into the second loading box 111. Similarly, the second one-way valve 112 has the same function as the first one-way valve 52.

[0036] The composite dehumidifier is made of a mixture of desiccant and magnesium powder. The second loading box 111 and the first loading box 51 are both made of heat-conducting material. The moisture is absorbed by the desiccant. The desiccant can be made of silica gel material. Silica gel is the most common desiccant and has good water absorption. It usually appears in the form of particles or beads and can absorb moisture in the surrounding environment. When the silica gel absorbs moisture to saturation, it can be dried by heating to a temperature of 100°C-120°C to restore its moisture absorption capacity. The dried silica gel can be used repeatedly. The reaction of magnesium and water can not only produce a large amount of hydrogen, causing the inner deformation capsule 7 and the outer shape deformation capsule 9 to swell, but also the temperature of about 100°C-200°C can dry the desiccant. At the same time, the high temperature can also make the inner deformation capsule 7 and the outer shape deformation capsule 9 expand better when heated.

[0037] The inner walls on both sides of the left and right sides of the mechanism box 1 are hinged with multiple sealing plates 12 corresponding to the multiple heat dissipation holes 3, and the inner walls of the heat dissipation holes 3 are fixedly connected with magnetic sealing pieces 13. The sealing plates 12 are rotated and adsorbed and fixed with the magnetic sealing pieces 13, so as to block and seal the heat dissipation holes 3 to prevent rainwater from seeping into the heat dissipation holes 3.

[0038] The sealing plate 12 includes a baffle plate 121, which is hinged to the inner wall of the mechanism box 1, and the outer end of the baffle plate 121 is fixedly connected to an edge-sealing iron sheet 122, and the front end of the baffle plate 121 is fixedly connected to an extension plate 123, and the extension plate 123 is pushed by the internal deformation bag 7 to swell upward, thereby pushing multiple extension plates 123 in turn, so that the multiple baffle plates 121 are rotated in turn to block the upper heat dissipation holes 3, so that the edge-sealing iron sheet 122 and the magnetic sealing sheet 13 are adsorbed and fixed, thereby increasing the sealing effect.

[0039] A plurality of indicator lights 14 are fixedly connected to the upper end of the mechanism box 1, a moisture detector is installed in the load-bearing bottom plate 2, and the plurality of indicator lights 14 are electrically connected to the moisture detector. When water is detected by the moisture detector, the plurality of indicator lights 14 are triggered to flash to remind passers-by and staff that there is a risk of electric leakage due to water seepage in the mechanism box 1.

[0040] A heat dissipation guide plate 15 is embedded at the bottom end of the load-bearing base plate 2, and the heat dissipation guide plate 15 is in contact with the spare box 11. The heat generated in the water seepage box 5 and the spare box 11 and the heat generated by the operation of the high-voltage switch operating mechanism body 4 are all conducted and evacuated to the ground through the heat dissipation guide plate 15, which can also act as a ground wire to prevent the outer end of the mechanism box 1 from conducting electricity.

[0041] Working principle:

[0042] When rainwater floods the load-bearing bottom plate 2 and penetrates into the mechanism box 1, rainwater penetrates into the seepage box 5 from the first one-way valve 52 at the upper end of the seepage box 5, contacts and reacts with the composite dehumidifier in the seepage box 5, absorbs moisture and releases a large amount of gas into the inner deformation bag 7 and the outer shape deformation bag 9 at the same time, causing them to swell inside and outside the box door respectively to block and seal the gaps between the mechanism box 1, the load-bearing bottom plate 2 and the box door. If rainwater continues to penetrate from the gap at the top of the box door, rainwater flows into the reserved groove 10 and enters the spare box 11. The composite dehumidifier in the spare box 11 also absorbs water and reacts to release gas, causing the inner deformation bag 7 and the outer shape deformation bag 9 to continue to swell and expand to the limit to wrap and seal the box door, thereby further preventing rainwater from seeping in, thereby effectively protecting the high-voltage switch operating mechanism body 4.

[0043] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0044] The present invention uses a composite dehumidifier to absorb water and release gas to make the inner deformation bag 7 and the outer deformation bag 9 swell and expand to shield and seal the gaps between the mechanism box body 1, the load-bearing bottom plate 2 and the box door. Water enters the mechanism box body 1 and penetrates into the water seepage box 5, so that the composite dehumidifier contacts rainwater and absorbs moisture and releases a large amount of gas, so that the gas enters the deformation bag 7 and the outer deformation bag 9, causing them to expand upward and stand upright to shield and seal the gaps between the mechanism box body 1 and the box door and the gaps between the load-bearing bottom plate 2 and the box door, thereby preventing rainwater from continuing to penetrate and protecting the high-voltage switch operating mechanism body 4. At the same time, the spare box 11 is used to guide the rainwater that continues to penetrate, and the composite dehumidifier inside it is also used to absorb water and release gas, so that the inner deformation bag 7 and the outer deformation bag 9 continue to swell and expand to the limit to wrap and seal the box door, thereby further preventing rainwater from penetrating, thereby effectively providing high protection to the high-voltage switch operating mechanism body 4.

[0045] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that those skilled in the art can understand.
