The water inlet pipe assembly is connected to the valve string press-fit module 8 and the water-cooled resistor assembly module 4, respectively. The water outlet pipe assembly is located on the outside of the cabinet and at the middle of the rear side of the cabinet. The water outlet pipe assembly is connected to the valve string press-fit module 8 and the water-cooled resistor assembly module 4, respectively. The valve string press-fit module 8, the water-cooled resistor assembly module 4, and the capacitor module 5 all extend along the height direction of the installation space.

[0040] In the utility model embodiment, the water-cooled DC ice-melting rectifier power valve group adopts a vertical structure design and has a rectangular shape in appearance.

[0041] The cabinet serves as the carrier and protective shell for the entire valve assembly, providing a safe operating environment for each internal module.

[0042] The space inside the cabinet is used to install and arrange key components such as valve string press-fit module 8, water-cooled resistor assembly module 4, and capacitor module 5, ensuring that they can work properly and be interconnected.

[0043] The valve string press-fit module 8 is located on the front left side of the installation space for easy operation and observation, while maintaining a close distance from external connections (such as water inlet pipe components) to reduce pipe length and connection complexity.

[0044] The valve string press-fit module 8, as the core component of the rectifier power valve group, is responsible for current control and conversion, and is a key component for realizing the DC ice melting function. The valve string press-fit module includes a water-cooled plate, thyristors, copper busbars, etc., which are uniformly press-fitted together.

[0045] In some embodiments, the water-cooled high-capacity DC ice-melting rectifier power valve group further includes a plate support beam 18, which is located on the right side of the valve string press-fit module 8 and connected to the valve string press-fit module 8. The upper and lower ends of the plate support beam 18 are respectively connected and fixed to the top plate and bottom plate of the installation space.

[0046] The water-cooled resistor assembly module 4 is located at the rear center of the installation space, maintaining an appropriate distance from the valve string press-fit module 8 to facilitate heat dissipation and electrical connection. The water-cooled resistor assembly module 4 reduces the heat generated by the valve string press-fit module 8 during operation through water cooling, ensuring stable system operation. Simultaneously, it is electrically connected to the valve string press-fit module 8 to jointly control and regulate the current. The water-cooled resistor assembly module 4 includes a water-cooled resistor and multiple support beams.

[0047] Capacitor module 5 is located at the rear right side of the installation space, maintaining an appropriate electrical connection distance from valve string press-fit module 8 and water-cooled resistor assembly module 4. Capacitor module 5 provides the necessary capacitance support for valve string press-fit module 8, stabilizing voltage and current fluctuations and improving the stability and efficiency of the entire system.

[0048] The inlet and outlet water piping assemblies are located on the left rear and rear center of the outer side of the cabinet, respectively, to avoid interference with internal electrical wiring and to facilitate connection and maintenance of external water sources. These assemblies provide cooling water circulation for the water-cooled resistor assembly module 4 and the valve string press-fit module 8, ensuring effective heat dissipation during high-load operation. The inlet water piping assembly supplies water to the system, while the outlet water piping assembly removes used hot water from the system.

[0049] The valve string press-fit module 8, water-cooled resistor assembly module 4, and capacitor module 5 all extend along the height of the installation space, effectively utilizing the three-dimensional space of the cabinet and making the entire valve assembly structure more compact and efficient. At the same time, this layout also helps improve the system's heat dissipation performance and the stability of electrical connections.

[0050] This application effectively utilizes the three-dimensional space of the cabinet by placing the valve string press-fit module 8 on the front left side of the installation space, the water-cooled resistor assembly module 4 in the rear middle section, and the capacitor module 5 on the rear right side, all extending along the height of the installation space. This makes the entire valve assembly structure more compact and improves space utilization. The valve string press-fit module 8, water-cooled resistor assembly module 4, and capacitor module 5 are designed as independent units, and the modular design makes the valve assembly easier to install, maintain, and upgrade. Furthermore, the inlet and outlet water pipe assemblies are respectively located on the rear left side and the middle rear side of the cabinet, avoiding cross-interference with internal electrical wiring and facilitating the connection and maintenance of external pipes, thus improving the safety and reliability of the system. At the same time, since the valve assembly adopts a vertical structure design, it can be adjusted with the adjustment of the valve string press-fit module 8. When the valve string press-fit module 8 is added or removed, the height of the valve assembly can also be increased or decreased accordingly, thereby effectively improving the scalability of the valve assembly.

[0051] Reference Figure 2 and Figure 4 According to the present invention, a water-cooled DC ice-melting rectifier power valve group is provided. The water-cooled DC ice-melting rectifier power valve group includes a wire support beam 19, which is located in front of the capacitor module 5 and on the right side of the capacitor module 5 and the water-cooled resistor assembly module 4. The valve string press-fit module 8 also includes a resistor wire 17 and a capacitor wire 20. The resistor wire 17 and the capacitor wire 20 are respectively routed through the wire support beam 19. The resistor wire 17 is used to connect to the water-cooled resistor assembly module 4, and the capacitor wire 20 is connected to the capacitor module 5.

[0052] Understandably, the cable management support beam 19 is located in front of the capacitor module 5 and to the right of the capacitor module 5 and the water-cooled resistor assembly module 4. The cable management support beam 19 primarily manages and guides the resistor wires 17 and capacitor wires 20, ensuring that these wires can be connected orderly from one module to another, avoiding tangled cables and improving system neatness. By rationally arranging the cable routing, the cable management support beam 19 helps save internal space, making the connections between modules more compact, while also leaving sufficient operating space for other components. Clear cable routing simplifies future maintenance. Technicians can more easily trace and handle specific wires or cables, reducing troubleshooting time.

[0053] The resistor wire 17 is used to electrically connect the power electronic components (such as thyristors) in the valve string press-fit module 8 to the water-cooled resistor assembly module 4, ensuring that the current can be correctly transmitted between the two, thereby realizing the functions of current regulation and power control.

[0054] The capacitor wire 20 connects the valve string press-fit module 8 to the capacitor module 5, enabling the capacitor to perform its energy storage and voltage smoothing functions, ensuring the stability of the output DC current. Through its effective connection with the capacitor module 5, the capacitor wire 20 helps reduce harmonic interference in the system and improves power quality.

[0055] Reference Figure 1 According to the present invention, a water-cooled DC ice-melting rectifier power valve group is provided. The cabinet includes a base assembly 6, a top cover plate 1 and multiple frame support beams 12. The top cover plate 1 is spaced above the base assembly 6. The multiple frame support beams 12 are connected between the base and the top cover plate 1. The base assembly 6, the top cover plate 1 and the multiple frame support beams 12 together enclose an installation space.

[0056] Understandably, the base assembly 6, located at the bottom of the entire cabinet, bears the weight of all internal modules, ensuring the entire device is stably placed on the ground. Typically, the base assembly 6 includes high-voltage insulators or other insulating materials to achieve electrical isolation, prevent current leakage, and ensure operator safety.

[0057] The top cover plate 1 is spaced above the base assembly 6 and is connected to the base assembly 6 via the frame support beam 12. The top cover plate 1, together with other components, forms a space.

[0058] The top cover 1, together with the base assembly 6 and the frame support beams 12, enhances the overall structural strength of the cabinet, ensuring that it will not deform or be damaged during transportation and use. Multiple frame support beams 12 connect the base assembly 6 and the top cover 1, forming a robust frame structure that provides the necessary mechanical strength and support for the entire cabinet, ensuring that each module can be stably installed and function properly.

[0059] The installation space formed by the base assembly 6, the top cover plate 1, and multiple frame support beams 12 provides an orderly installation environment for all internal modules, enabling each functional module to operate under optimal conditions.

[0060] Reference Figure 3 According to the present invention, a water-cooled DC ice-melting rectifier power valve group is provided, which further includes a valve string fixing bracket 16, which is connected between the top cover plate 1 and the valve string press-fit module 8.

[0061] Understandably, the main function of the valve string fixing bracket 16 is to fix and support the valve string press-fit module 8, ensuring the stability of the valve string within the cabinet and preventing displacement due to vibration or other reasons during equipment operation. Simultaneously, the number of valve string fixing brackets 16 can be increased or decreased according to the number of valve string press-fit modules 8 in the installation space, facilitating the expansion and adjustment of the water-cooled DC ice-melting rectifier power valve group.

[0062] Reference Figure 1 According to the present invention, a water-cooled DC ice-melting rectifier power valve group is provided, wherein the base assembly 6 includes an upper frame, a lower frame and a plurality of insulators, the lower frame and the upper frame are spaced apart, and the plurality of insulators are arranged around the lower frame and the upper frame.

[0063] Understandably, the upper frame is located above the base assembly 6 and is spaced apart from the lower frame by insulators. As part of the base assembly 6, the upper frame provides additional mechanical support, enhancing the overall rigidity of the base. Together with the lower frame, it forms a stable platform for supporting and securing the internal modules.

[0064] The lower frame is located at the bottom of the base assembly 6 and directly contacts the ground or other supporting surface. The lower frame is the foundation of the entire cabinet, bearing the weight of all internal modules and ensuring that the equipment can be placed stably on the ground.

[0065] Multiple insulators are arranged between the lower and upper frames, isolating them. The main function of the insulators is to provide electrical isolation, preventing the risk of short circuits between the high-voltage section and ground. This ensures that the base assembly 6 can maintain a safe operating condition even in high-voltage environments. In addition to providing electrical isolation, the insulators also provide necessary mechanical support, maintaining a fixed distance between the upper and lower frames and ensuring the structural stability of the base assembly 6.

[0066] The function of the appendix features in the solution is explained separately: According to the water-cooled DC ice-melting rectifier power valve group provided by this utility model, the capacitor module 5 includes multiple capacitors, a first fixed beam 3, a second fixed beam 21, a third fixed beam and a fourth fixed beam 24. The multiple capacitors are stacked along the height direction. The first fixed beam 3, the second fixed beam 21, the third fixed beam and the fourth fixed beam 24 are arranged around the outer periphery of the multiple resistors and are connected to the multiple resistors. The two ends of the first fixed beam 3, the second fixed beam 21, the third fixed beam and the fourth fixed beam 24 along the height direction are respectively connected to the base assembly 6 and the top cover plate 1.

[0067] Understandably, the multiple capacitors in capacitor module 5 are stacked along the height direction, and the fixing beam is arranged around the outer periphery of the multiple capacitors, providing a sturdy support structure for the capacitors and preventing the capacitors from being displaced or damaged due to vibration or external forces during operation.

[0068] The fixed beam not only supports the capacitor but also connects to the base assembly 6 and the top cover plate 1 at its two ends along the height direction, forming a complete structural frame. This enhances the rigidity and stability of the entire capacitor module 5, ensuring its long-term stable operation in complex working environments.

[0069] Reference Figure 1 and Figure 2 According to the present invention, a water-cooled DC ice-melting rectifier power valve group is provided. The water-cooled DC ice-melting rectifier power valve group further includes a first output bracket and a second output bracket. The first output bracket is disposed on the base assembly 6, and the second output bracket is disposed on the top cover plate 1. The output copper busbar of the valve string press-fit module 8 is fixed to the base assembly 6 through the first output bracket, or the output copper busbar of the valve string press-fit module 8 is fixed to the top cover plate 1 through the second output bracket.

[0070] Understandably, the main function of the output bracket is to fix and support the output copper busbars of the valve string press-fit module 8. The output copper busbars are crucial current output channels in the rectifier power valve group; they need to be securely fixed in a suitable position to ensure stable and reliable current transmission. By providing a robust support point, the output bracket effectively prevents the output copper busbars from shifting or deforming due to vibration or external forces during operation.

[0071] By precisely positioning and arranging the output bracket, a tighter and more reliable electrical connection is ensured between the output copper busbar and other electrical components (such as capacitors and resistors) in the rectifier power valve group. The design of the output bracket simplifies the installation process of the output copper busbar of the valve string press-fit module 8. Standardized connection interfaces and fixed installation positions allow for quick and easy fixing and connection of the output copper busbar.

[0072] Reference Figure 1 and Figure 3 According to the present invention, a water-cooled DC ice-melting rectifier power valve group is provided. The water-cooled DC ice-melting rectifier power valve group also includes a water pipe clamp 13. The water inlet pipe assembly and the water outlet pipe assembly are respectively connected to the outer wall of the cabinet through the water pipe clamp 13.

[0073] Understandably, the pipe clamp 13 provides a reliable mechanical fixation for the inlet and outlet water pipe assemblies, ensuring their accurate and stable positioning on the outer wall of the cabinet. Even if vibration or impact occurs during transportation or operation, the water pipes will not shift or detach. By evenly distributing the weight of the water pipes, the pipe clamp 13 reduces single-point stress, avoiding structural deformation or damage caused by localized overload, thereby extending the service life of the water pipes.

[0074] Reference Figure 2According to the present invention, a water-cooled DC ice-melting rectifier power valve assembly includes an inlet pipe assembly comprising a main inlet pipe 10, a resistor inlet pipe 14, and a valve string inlet pipe 15. The main inlet pipe 10 is connected to the water-cooled resistor assembly module 4 via the resistor inlet pipe 14, and is also connected to the valve string press-fit module 8 via the valve string inlet pipe 15. The outlet pipe assembly comprises a main outlet pipe 2, a resistor outlet pipe 25, and a valve string outlet pipe 26. The main outlet pipe 2 is connected to the water-cooled resistor assembly module 4 via the resistor outlet pipe 25, and is also connected to the valve string press-fit module 8 via the valve string outlet pipe 26.

[0075] Understandably, the main inlet pipe 10 is the starting point of the entire water inlet piping system, located on the outer wall of the cabinet (left rear), serving as the main inlet for coolant entering the system. The main inlet pipe 10 is responsible for introducing coolant from an external cooling source into the system and distributing it to subsequent branch pipes. Valves or flow regulators can be used to control the flow rate and pressure of the coolant entering the system, ensuring a stable water supply.

[0076] The resistor inlet pipe 14 branches off from the main inlet pipe 10 and connects directly to the water-cooled resistor assembly module 4, specifically supplying coolant to the module to ensure sufficient cooling support and maintain its operating temperature within a safe range. The water supply and pressure can be independently adjusted according to the actual needs of the water-cooled resistor assembly module 4 to optimize the cooling effect.

[0077] The valve string inlet pipe 15 also branches off from the main inlet pipe 10 and connects directly to the valve string press-fit module 8, providing coolant to the valve string press-fit module 8. This helps manage the heat generated by the thyristors and other heat-generating components within the module, ensuring its normal operation. Similarly, the water supply and pressure can be independently adjusted according to the needs of the valve string press-fit module 8 to ensure optimal cooling.

[0078] Main outlet pipe 2 is the endpoint of the entire coolant outlet piping system, located on the outer wall of the cabinet (rear center), serving as the main outlet for the coolant discharge system. Main outlet pipe 2 is responsible for collecting the coolant flowing from each module and discharging it back to the external cooling system. A pressure relief valve or other safety devices can be installed to prevent excessive internal system pressure and ensure safe operation.

[0079] The resistor outlet pipe 25 branches off from the main outlet pipe 2 and connects directly to the water-cooled resistor assembly module 4. It is specifically designed to collect the coolant flowing from the water-cooled resistor assembly module 4, ensuring that the heat within the module is effectively dissipated. The drainage volume and pressure can be independently adjusted according to actual needs to optimize the cooling cycle.

[0080] The valve string outlet pipe 26 branches off from the main outlet pipe 2 and connects directly to the valve string press-fit module 8. It is responsible for collecting the coolant flowing out of the valve string press-fit module 8, ensuring that the heat within the module is effectively dissipated. The drainage volume and pressure can also be independently adjusted according to actual needs to ensure optimal cooling performance.

[0081] By rationally designing the inlet and outlet water pipe components, it is ensured that each heat-generating module receives sufficient coolant supply and effective heat dissipation, thereby improving the cooling efficiency of the entire system.

[0082] In some embodiments, pressure relief valves are provided at the top of the inlet pipe assembly and the outlet pipe assembly, and equipotential bonding points are provided on the upper and lower sides.

[0083] In some embodiments, the resistor inlet pipe 14, the valve string inlet pipe 15, the resistor outlet pipe 25, and the valve string outlet pipe 26 are connected to the water-cooled resistor assembly module 4 and the valve string press-fit module 8 via water nozzles and are fixed by the water pipe support bend 9.
