Description

Technical Field

[0001] This utility model belongs to the field of power electronics technology, and in particular relates to an integrated TCR railway traction contact network de-icing device. Background Technology

[0002] Electrified railways have gradually covered most of my country's main railway network. If the traction network loses power due to ice storms, it could lead to major accidents. The overhead contact line is directly exposed to the air and is highly susceptible to external factors such as climate and terrain. Icing is frequent in cold and humid regions, seriously affecting railway safety. Currently, the solution of converting alternating current to direct current to heat iced transmission lines and melt the ice is a practical, economical, and effective technical method and measure to prevent ice storm accidents. Existing ice-melting devices are usually transported to the site in cabinet or component form for installation. Due to terrain and climate conditions, especially in permafrost environments, installation is difficult, increasing costs and hindering subsequent maintenance. Summary of the Invention

[0003] The purpose of this invention is to provide an integrated TCR railway traction contact network de-icing device. The integrated design facilitates the overall transportation of the de-icing device and reduces the difficulty and cost of on-site installation.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] An integrated TCR railway traction contact network de-icing device includes a container, which is divided into a low-voltage control room, a valve group room, and a high-voltage operation room. The low-voltage control room is equipped with a control cabinet and a distribution box; the valve group room is equipped with a valve group; and the high-voltage operation room is equipped with a circuit breaker trolley, a voltage transformer, a surge arrester, and a fuse.

[0006] The top of the container is equipped with a support insulator base, a wall bushing mounting base, and a wind turbine mounting base; the support insulator base is used to install support insulators, the wall bushing mounting base is used to install wall bushings, and the wind turbine mounting base is used to install wind turbines.

[0007] The low-pressure operating room and the valve group room are separated by a partition, which is fixedly connected to the container. The lower part of the partition is provided with a wire groove hole, and the upper part of the partition is provided with an observation window.

[0008] The bottom of the valve assembly is connected to the container via an insulator.

[0009] The container has a base reinforcement plate fixed to its bottom plate, and the base reinforcement plate is fixedly connected to the insulator via an adapter plate.

[0010] A detachable grille connects the high-pressure operating chamber and the valve assembly chamber.

[0011] It also includes sheet metal beams and fixed beams. The fixed beams are set between the high-pressure operating room and the valve group room. The fixed beams are fixedly connected to the container. The detachable grille is connected to the fixed beams. The fixed beams are equipped with Z-shaped sheet metal beams.

[0012] The high-voltage operating room is welded with a current transformer base and a surge arrester base; the current transformer base is used to install the current transformer, and the surge arrester base is used to install the surge arrester; the circuit breaker trolley is connected to the container through a circuit breaker trolley slide, and the circuit breaker trolley slide is fixed to the bottom plate of the container by bolts.

[0013] The wall sleeve mounting base and the fan mounting base are both outward-facing boss structures.

[0014] A low-voltage inlet elbow is fixedly connected to the container body at the rear of the low-voltage control room.

[0026] The present invention will now be described in detail with reference to the accompanying drawings. However, it should be noted that the implementation of the present invention is not limited to the following embodiments.

[0027] See Figure 1 , Figure 2 An integrated TCR railway traction contact network de-icing device includes a container 4, which is divided into a low-voltage control room 1, a valve group room 2, and a high-voltage operation room 3 from left to right. The low-voltage control room 1 is equipped with a control cabinet 9 and a distribution box 15; the valve group room 2 is equipped with a valve group 11; and the high-voltage operation room 3 is equipped with a circuit breaker trolley 13, a voltage transformer 14, a surge arrester 12, and a fuse.

[0028] See Figure 1 , Figure 2 The top of container 4 is fixedly connected with several supporting insulator bases 8, wall bushing mounting bases 20, and wind turbine mounting bases 19. The supporting insulator bases 8 are used to install supporting insulators 7, the wall bushing mounting bases 20 are used to install wall bushings 6, and the wind turbine mounting bases 19 are used to install wind turbines 5. Both the wall bushing mounting bases 20 and the wind turbine mounting bases 19 have outward-facing boss structures, see... Figure 5 , Figure 6 The outward-facing portion has mounting holes for connecting the wall bushing 6 and the motor. The busbar, along with fittings and supporting insulators 7, is mounted on the supporting insulator base 8. The busbar connects to the wall bushing 6 via fittings and aluminum stranded wire. Inside the container 4, the wall bushing 6 is connected to the incoming side of the circuit breaker 13 via a conductor bar, and then the conductor bar from the outgoing side of the circuit breaker 13 connects to the wall bushing 6 and returns to the outside of the container 4. The front end of the voltage transformer 14 is connected to the copper busbar at the incoming end of the circuit breaker trolley 13 via aluminum stranded wire. The rear end of the voltage transformer 14 is connected to the lower end of the fuse 12 via a conductor, and the upper end of the fuse 12 is connected to the copper busbar at the incoming end of the circuit breaker trolley 13 via a conductor, so that the fuse 12 and the voltage transformer 14 are connected in series and then in parallel with the copper busbar at the incoming end of the circuit breaker trolley 13.

[0029] See Figures 1-4The low-pressure control room and valve assembly room 2 are separated by a partition 10, which is fixedly connected to the container 4. The lower part of the partition 10 has cable tray holes through which cables can pass to the control cabinet 9. The upper part of the partition 10 has an observation window 17 for observation of the valve assembly room 2 from the control room. The main body of the partition 10 is a partition plate, which is fixedly connected to the container 4 with bolts.

[0030] The bottom of valve assembly 11 in valve assembly chamber 2 is connected to container 4 via insulator 22. A foot reinforcement plate 24 is welded and fixed to the bottom plate of container 4, and the foot reinforcement plate 24 is fixedly connected to the insulator 22 via an adapter plate 23. The foot reinforcement plate 24 ensures better load-bearing capacity at the insulator 22, converting the point force on the insulator 22 into a surface force. Simultaneously, the foot reinforcement plate 24 allows for more precise machining of the insulator 22 holes in valve assembly 11, facilitating on-site installation. The top of valve assembly chamber 2 is connected via a through-wall sleeve 6. Inside container 4, a conductive busbar connects to the upper end of valve assembly 11, and then the busbar exits from the lower end, connecting to the low-voltage through-wall sleeve 16 on the side wall for grounding return.

[0031] A removable grille 25 connects the high-voltage operating room 3 and the valve assembly room 2, serving as a partition. A fixed beam is installed between the high-voltage operating room 3 and the valve assembly room 2, and is fixedly connected to the container 4. The removable grille 25 is also fixedly connected to the fixed beam. A U-shaped sheet metal beam 26 is installed on the fixed beam, which is used to install insulators supporting the copper busbars. A current transformer base and a surge arrester 12 base are welded to the high-voltage operating room 3; the current transformer base is used to install the current transformer, and the surge arrester 12 base is used to install the surge arrester 12. The circuit breaker trolley 13 is connected to the container 4 via a circuit breaker trolley slide, which is fixed to the bottom plate of the container 4 by bolts.

[0032] A low-voltage inlet elbow 18 is fixedly connected to the lower part of the container 4 at the rear of the low-voltage control room 1. The incoming cable enters the container 4 through the low-voltage inlet elbow 18. The elbow structure of the low-voltage inlet elbow 18 has an opening facing downwards, and with the help of fireproof putty, it can effectively prevent water and dust. After entering the container, the incoming cable is connected to the distribution box 15 fixed on the upper rear side of the container 4.

[0033] The integrated TCR railway traction contact network de-icing device generates heat in valve assembly 11 during operation, thus requiring heat dissipation. The heat dissipation method is air cooling. A fan 5 is installed at the top of valve assembly chamber 2, directly above valve assembly 11. Ventilation louvers 21 are provided on the front and rear doors of valve assembly chamber 2. During operation, the fan 5 draws heat outwards, creating negative pressure inside the chamber, which is then cooled by air intake through the louvers 21.

[0034] This invention integrates the equipment into a single unit using a container (4), facilitating transportation without additional packaging. On-site installation requires no fixed base, reducing the need for construction in frozen soil. The de-icing device is pre-installed after production, with the aluminum stranded wire and other components fabricated for direct on-site assembly, reducing installation difficulty. This invention abandons the high-voltage switchgear cabinet structure, independently installing the circuit breaker trolley (13) and voltage transformer (14), reducing costs, shortening the construction period, and facilitating later installation and maintenance.

However, it should be understood that this utility model is not limited to the specific embodiments described above. Based on the disclosed embodiments, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions. Due to space limitations and for the sake of brevity, not all of these combined solutions have been described.
