[0002] In modern straddle-type monorail vehicle systems, lightning arresters are one of the key components used to protect trains and their passengers from lightning damage. The lightning arrester is installed under the train body. When lightning strikes, the lightning arrester can quickly direct the high-voltage current to the ground to ensure the safety of the train and its key equipment. However, the lightning arrester installation structures for straddle-type monorail vehicles in the prior art face several significant problems.

[0003] First, straddle-type monorail vehicles are designed to be compact, and the space under the vehicle body is very limited, resulting in the need to make efficient use of the limited space for the lightning arrester and its mounting brackets. At the same time, the lightning arrester needs to coexist with other key components, which further limits the available installation space.

[0004] Second, the operating environment of straddle-type monorail vehicles is harsh. The train operates in various weather conditions, and the lightning arrester and its mounting brackets must be able to withstand environmental influences such as high temperature, low temperature, humidity, and dust. Straddle-type monorail vehicles have extremely high requirements for the insulation and voltage withstand of lightning arresters. To ensure the effective conduction of high-voltage current during lightning strikes and avoid interference or damage to the train's electrical system, the lightning arrester and its installation structure must have excellent insulation performance and voltage withstand capacity. This means that the mounting bracket not only needs to provide mechanical support but also needs to have good insulation and voltage withstand characteristics. Summary of the Utility Model

[0027] In order to solve the problem of poor insulation performance of lightning arresters in the prior art, the present application provides a monorail vehicle lightning arrester assembly.

[0028] See Figure 1 , Figure 2 and Figure 6 , in a possible implementation, it includes: a lightning arrester 6;

[0029] A thick insulating plate 3, which is connected to the lightning arrester 6 through lightning arrester mounting bolts 5;

[0030] See Figure 4 , a thin insulating plate 2, which is connected to the thick insulating plate 3 through insulating plate mounting bolts 4;

[0031] See Figure 3 , a bracket 1, whose material is stainless steel, with an insulating paint sprayed on the surface, having a bottom surface and two opposite side surfaces connected to the bottom surface, and the two side surfaces have outwardly bent edges 11;

[0032] The thick insulating plate 3 and the thin insulating plate 2 are installed on the bracket 1 through insulating plate mounting bolts 4;

[0033] The thick insulating plate 3 is provided with a drainage groove 7 on the surface where the lightning arrester 6 is installed. The drainage groove 7 is a groove on the surface of the thick insulating plate 3, and two ends or more than two ends of the drainage groove 7 are on the same side or different sides of the thick insulating plate 3;

[0034] The thick insulating plate 3 and / or the thin insulating plate 2 are provided with counterbores 8 at positions corresponding to the lightning arrester mounting bolts 5, and the lightning arrester mounting bolts 5 are placed in the counterbores 8;

[0035] The position of the thick insulating plate 3 where the insulating plate mounting bolts 4 are installed is provided with counterbores 8, and the insulating plate mounting bolts 4 are placed in the counterbores 8. After installing the insulating plate mounting bolts 4, the counterbores 8 are filled with an insulating glue layer 9.

[0036] The lightning arrester 6 is connected to the thick insulating plate 3 through the lightning arrester mounting bolts 5. The thick insulating plate 3 is then connected to the thin insulating plate 2 through the insulating plate mounting bolts 4. The thin insulating plate 2 and the thick insulating plate 3 are fixed together on the stainless - steel bracket 1, and the surface of the bracket 1 is sprayed with insulating paint to increase the insulation performance. The surface of the thick insulating plate 3 is provided with a drainage groove 7, which can drain the surface water and avoid the influence of water accumulation on the performance of the lightning arrester. The design of the counterbores 8 ensures the accurate position of the mounting bolts and improves the insulation performance by filling the insulating glue layer 9.

[0037] In the above solution, the arrester assembly of the monorail vehicle is reasonably designed and has a compact structure. By using the thick insulating plate 3 and the thin insulating plate 2, a good insulating effect is provided. The design of the drain groove 7 effectively drains the surface water, avoids the influence of water accumulation on the performance of the arrester, and ensures the stable operation of the arrester. By filling the counterbore 8 with an insulating adhesive layer 9, the insulating performance of the system is further improved, and the safety and reliability of the system are enhanced.

[0038] In another possible implementation, the thick insulating plate 3 and the thin insulating plate 2 can use different insulating materials, such as fiberglass-reinforced polyester GPO3 material with a comparative tracking index CTI≥600, to improve durability and insulating effect. In addition, the insulating paint sprayed on the surface of the bracket 1 can also be replaced with other coatings with similar insulating properties to adapt to different application environments and requirements.

[0039] See Figure 1 and Figure 5 , in a possible implementation, the drain groove 7 is arranged between the counterbore 8 of the insulating plate mounting bolt 4 and the arrester 6. The drain groove 7 is arc-shaped and is arranged at the four corners of the thick insulating plate 3.

[0040] The drain groove 7 is designed to be arc-shaped and is located between the counterbore 8 of the insulating plate mounting bolt 4 and the arrester 6, which helps to guide the water to the four corners of the thick insulating plate 3, thus effectively draining the surface water and avoiding the influence of water accumulation on the performance of the arrester.

[0041] The design of the arc-shaped drain groove 7 enables the water to be quickly drained, prevents water accumulation, and improves the safety and reliability of the arrester.

[0042] In a possible implementation, the drain groove 7 is arranged between the counterbore 8 of the insulating plate mounting bolt 4 and the arrester 6. The drain groove 7 is in a grid shape, the arrester 6 is installed in the middle of the grid, and the insulating plate mounting bolt 4 is placed at the four corners of the grid.

[0043] The grid-shaped drain groove 7 is arranged between the counterbore 8 of the insulating plate mounting bolt 4 and the arrester 6. Through the design of the grid structure, the surface water can be more effectively guided to multiple drain outlets, thus better draining the surface water and ensuring the normal operation of the arrester.

[0044] The design of the grid-shaped drain groove 7 increases the effective drainage path, improves the drainage efficiency, avoids the water staying on the surface of the thick insulating plate 3 for too long and affecting the performance of the arrester. At the same time, the grid structure also enhances the overall strength and durability of the drain groove.

[0045] In another embodiment, the size and depth of the grid-shaped drainage trough can be adjusted as needed to optimize the drainage effect. In addition, the design of the drainage trough can be adjusted according to different application scenarios, such as adopting a more complex drainage network design to meet more drainage requirements.

[0046] In a possible embodiment, refer to Figure 5 , the thick insulating plate 3 is provided with a counterbore 8 at a position corresponding to the arrester mounting bolt 5, and the arrester mounting bolt 5 is placed in the counterbore 8.

[0047] The thick insulating plate 3 is provided with a counterbore 8 at a position corresponding to the arrester mounting bolt 5, and the arrester mounting bolt 5 is placed in the counterbore 8. This design ensures the accurate position of the arrester mounting bolt and provides a certain degree of protection, making it not easily damaged by external mechanical forces.

[0048] In a possible embodiment, the arrester mounting bolt 5 is placed in the counterbore 8. After installing the arrester mounting bolt 5, the counterbore 8 is filled with an insulating adhesive layer 9.

[0049] The arrester mounting bolt 5 is installed in the counterbore 8, and after installation, the insulating performance is further improved by filling the insulating adhesive layer 9. The insulating adhesive layer 9 filled in the counterbore 8 can effectively prevent the influence of external moisture and pollutants on the bolt, thus ensuring the long-term stability and reliability of the bolt.

[0050] By filling the insulating adhesive layer 9 in the counterbore 8, not only the insulating performance of the arrester mounting bolt 5 is enhanced, but also the protection ability of the bolt is improved, reducing the performance degradation caused by environmental factors and extending the service life of the arrester assembly.

[0051] In a possible embodiment, the thick insulating plate 3 and the thin insulating plate 2 are made of glass fiber-reinforced polyester GPO3 material with a comparative tracking index CTI≥600.

[0052] The thick insulating plate 3 and the thin insulating plate 2 are made of glass fiber-reinforced polyester GPO3 material with a comparative tracking index CTI≥600. This material has excellent electrical insulation performance and mechanical strength, can effectively prevent the occurrence of tracking phenomenon, and improves the durability and safety of the insulating plate.

[0053] Using glass fiber-reinforced polyester GPO3 material with a comparative tracking index CTI≥600 to make the thick insulating plate 3 and the thin insulating plate 2 can significantly improve the insulating performance, prevent the occurrence of tracking phenomenon, and ensure the long-term stable operation of the arrester. At the same time, this material has good mechanical strength and heat resistance, extending the service life of the insulating plate.

[0054] In a possible implementation, the drainage groove 7 has different depths on the surface of the thick insulating plate 3, and the depth of the drainage groove 7 increases in the direction towards the edge of the thick insulating plate 3.

[0055] In the above solution, the depth of the drainage groove 7 gradually deepens from the center of the thick insulating plate 3 to the periphery, which is conducive to draining accumulated water and ensuring excellent insulation performance in bad weather and harsh environments.

[0056] The single-rail vehicle lightning arrester assembly as an embodiment is described as follows:

[0057] The lightning arrester installation structure is composed of Figure 1 and Figure 2 as shown: including a bracket 1, a thin insulating plate 2, a thick insulating plate 3, insulating plate installation bolts 4, lightning arrester installation bolts 5 and supporting nuts and washers.

[0058] The bracket 1 is made of stainless steel. The bent side 11 on the side of the bracket faces outward, and there is no bent side at the bottom, and the surface is sprayed with insulating paint. The structure is as Figure 3 shown.

[0059] The thin insulating plate 2 is made of GPO3 with a comparative tracking index CTI≥600. Its structure is as Figure 4 shown.

[0060] The thick insulating plate 3 is made of GPO3 with a comparative tracking index CTI≥600. Its structure is as Figure 5 shown. There are drainage grooves 7 around the four insulating plate installation bolt holes / counterbores 8 on the upper surface. The drainage grooves 7 can not only drain accumulated water in time to prevent the formation of a conductive path, but also increase the creepage distance; counterbores 8 are provided on both the front and back sides for placing the bolt heads of the installation bolts and reserving space for applying sealant.

[0061] The relationship between the components of the lightning arrester installation structure is as Figure 6 shown, that is, the thick insulating plate 3 and the lightning arrester 6 body are fastened by bolts, namely the lightning arrester installation bolts 5 in Figure 1 . The bolt ends are sunk into the thick insulating plate 3, and then covered with the thin insulating plate 2 to ensure the insulation of the bolts from the outside. The thick insulating plate 3 and the thin insulating plate 2 are installed on the bracket 1 together by bolts, that is, the insulating plate installation bolts 4, and the bolt ends are also sunk into the thick insulating plate 3. The counterbore areas of the installation bolts are filled with a sealant layer 9 to ensure complete isolation of the bolt end faces from the outside.

[0062] The thick insulating plate 3 is provided with a drainage groove 7. The drainage groove 7 can not only drain accumulated water in time to prevent the formation of a conduction path, but also increase the creepage distance. The front and back sides are provided with counterbores 8 for placing the bolt heads of the mounting bolts and reserving space for applying sealant. After applying sealant, it can ensure that the bolt end faces are completely isolated from the outside, further ensuring... Adopting a double-insulation structure, the insulation withstand voltage reliability is relatively high; in the form of a double-layer insulating plate, it has the characteristics of small volume and high insulation withstand voltage level, and can ensure the safe operation of the monorail vehicle under harsh weather and abnormal conditions.

[0063] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts between the various embodiments, reference can be made to each other.
