Description

Technical Field

[0001] This utility model belongs to the field of reactive power compensation devices and relates to a direct-mounted water-cooled SVG container. Background Technology

[0002] Patent No.: CN205986169U, a 35kV container water-cooled reactive power compensation device. This patent discloses a device that mainly includes a container, a water-cooling module, external piping, a water-cooled radiator, and a control cabinet. The main design is a new arrangement of reactive power compensation devices. This device has a small footprint, which can save economic costs. It adopts water-cooling heat dissipation, which has low noise and can reduce environmental pollution.

[0003] However, the containerized water-cooled static var compensator has the following drawbacks: each power module is arranged in series for heat dissipation. As the number of modules increases, the cooling medium gets closer to the end, the lower the pressure, the greater the flow resistance, and the continuously rising temperature of the cooling medium. Therefore, the heat dissipation performance of the end module is greatly reduced, which ultimately affects the operation of the entire SVG. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a direct-mount water-cooled SVG container that optimizes the water-cooling pipeline layout to achieve the advantages of uniform heat dissipation of the power module and high operating quality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A direct-mount water-cooled SVG container includes a container, inside which are installed an SVG control cabinet, a water turbine control cabinet, and multiple power cabinets;

[0007] The SVG control cabinet and water turbine control cabinet are located on one side of the container, while multiple power cabinets are arranged side by side on the other side of the container.

[0008] The water turbine control cabinet is connected to an inlet pipe and an outlet pipe. The inlet pipe is located at the bottom of the container, and the outlet pipe is located at the top of the container.

[0009] Each power cabinet contains multiple power modules, which are arranged in an array on a vertical plane. In each column, the power modules in adjacent rows are grouped in pairs. The two power modules in the same group are connected in series through capillary tubes. The power modules at the bottom of the same group are connected to the water inlet pipe through capillary tubes, and the power modules at the top are connected to the water outlet pipe through capillary tubes. Different groups are connected in parallel between the water inlet pipe and the water outlet pipe.

[0010] Preferably, the bottom of the power cabinet is fixed to the bottom of the container using a king-shaped structural beam, and the sides of the power cabinet are connected to the side wall of the container using sheet metal parts.

[0011] Preferably, there are three power cabinets. The incoming line of each power cabinet is connected to the bottom side using copper busbars, and the outgoing line is connected to the neutral point copper busbar on the top layer. The ends of the three power cabinets are connected together to form a neutral point, and the three power cabinets constitute a three-phase power cabinet.

[0012] Preferably, an air vent valve is installed at the end of the water outlet pipe away from the water turbine control cabinet, and a drain valve is installed at the end of the water inlet pipe away from the water turbine control cabinet.

[0013] Preferably, the outlet and inlet water pipes are extended at the end furthest from the water heater control cabinet.

[0014] Preferably, the top of the container has an arched structure.

[0015] Preferably, an air conditioner is installed on the outside of the container, with the air conditioner vents connected to the inside of the container. A deflector is installed at the air conditioner vents, with the deflector facing the power cabinet.

[0016] Preferably, each power cabinet contains 19 power modules arranged in four layers, with the power modules in each cabinet arranged from bottom to top in a sequence of 5, 5, 5, and 4.

[0017] Preferably, each power cabinet is equipped with 18 power modules, arranged in four layers, with the power modules in each power cabinet arranged from bottom to top in a sequence of 5, 5, 4, 4.

[0018] Preferably, each power cabinet is equipped with 17 power modules, arranged in four layers. The power modules in each power cabinet are arranged from bottom to top in the order of 5, 5, 4, and 3, with the three power modules on the top layer being centrally located.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] This invention groups the power modules arranged in an array, with adjacent rows of power modules forming pairs. Within the same group, two power modules are connected in series via capillary tubes. The bottom power modules within the same group are connected to the water inlet pipe via capillary tubes, and the top power modules are connected to the water outlet pipe via capillary tubes. Different groups are connected in parallel between the water inlet and outlet pipes. This series-parallel connection method reduces the number of power modules connected to each heat dissipation loop, improves the heat dissipation effect of the top power modules, balances the flow and pressure of the cooling medium in each module, avoids the degradation of the end heat dissipation performance, and achieves the advantages of uniform heat dissipation and high operating quality.

[0033] like Figure 1 and Figure 2 As shown, the container-type water-cooled reactive power compensation device of this utility model includes a container 1. The container 1 is designed with three power cabinets 12, an SVG control cabinet 2, a water turbine control cabinet, and water-cooled pipes 5 connected to the water turbine control cabinet. The SVG control cabinet 2 and the water turbine control cabinet are located on one side of the container 1, and the three power cabinets 12 are arranged side by side on the other side of the container 1 to form a three-phase power cabinet.

[0034] Each phase power cabinet 12 is supported at the bottom by a king-shaped structural beam 10, which is fixed to the bottom of the container 1. The king-shaped structural beam 10 is made of SMC material and designed in a king-shaped shape to effectively bear the weight of the power cabinet 12 and ensure the stability of the structure. The sides of the power cabinet 12 are connected to the side wall of the container 1 through sheet metal parts 3. The interior of each phase power cabinet 12 consists of insulating material 8, power modules 4, copper busbars, and sheet metal parts 3 that fix the power modules 4, all connected by fasteners.

[0035] The three power cabinets 12 adopt a star connection method. The ends of the three power cabinets 12 are connected together to form a neutral point, and the line voltage is obtained by subtracting the phase voltages from each other. This reduces the insulation requirements of the equipment, effectively reduces the equipment cost, and improves the safety of the electrical system.

[0036] The incoming lines for each phase's power cabinet 12 are located on the bottom side and connected using copper busbars, while the outgoing lines are connected to the neutral point copper busbar on the top layer. By connecting the power cabinets 12 in series, the stability and efficiency of the electrical connection are ensured.

[0037] In terms of cooling, the water cooling pipeline 5 is divided into two lines: one is the inlet pipeline and the other is the outlet pipeline. They are distributed at the bottom and top of container 1 in a bottom-in, top-out manner. The inlet pipeline is located at the bottom of container 1 and the outlet pipeline is located at the top of container 1. The circulating flow of the pipeline provides cooling for the power module 4 of the equipment.

[0038] The water-cooled pipeline 5 uses capillary tubes 11 to dissipate heat from the power modules 4. The power modules 4 are connected to each other by capillary tubes 11. The inlet and outlet water pipelines are connected to the capillary tubes 11 at the bottom and top, respectively. The material of the capillary tubes 11 is FEP.

[0039] Each power cabinet 12 contains multiple power modules 4, which are arranged in an array on a vertical plane. In each column, the power modules 4 in adjacent rows are paired up. The two power modules 4 in the same group are connected in series through capillary tubes 11. The power modules 4 at the bottom of the same group are connected to the water inlet pipe through capillary tubes 11, and the power modules 4 at the top of the same group are connected to the water outlet pipe through capillary tubes 11. Different groups are connected in parallel between the water inlet pipe and the water outlet pipe.

[0040] In this embodiment, as Figure 4As shown, a total of 57 power modules 4 are set up. For the power cabinet 12 with 57 power modules 4, there are three power cabinets 12. Each power cabinet 12 contains 19 power modules 4, arranged in four layers. The power modules 4 in each power cabinet 12 are arranged from bottom to top in a sequence of 5, 5, 5, 4. The empty power module 4 mounting position on the top layer is placed in the farthest upper right corner for easy cooling and module maintenance. In this power cabinet 12, the top two layers of power modules 4 form a group, and the bottom two layers of power modules 4 form a group. Two power modules 4 in the same group are connected in series by capillary tubes 11. The bottom power module 4 in the same group is connected to the water inlet pipe by capillary tubes 11, and the top power module 4 is connected to the water outlet pipe by capillary tubes 11. Different groups are connected in parallel between the water inlet pipe and the water outlet pipe.

[0041] An air vent valve is installed at the end of the water outlet pipe furthest from the water turbine control cabinet, and a drain valve is installed at the end of the water inlet pipe furthest from the water turbine control cabinet. To ensure consistent cooling performance for each module, the water outlet and inlet pipes extend a certain distance at the end furthest from the water turbine control cabinet, ensuring uniform flow of coolant and improving heat dissipation.

[0042] like Figure 3 As shown, the top cover of container 1 adopts a micro-arched structure, which is bolted to the side panel of container 1 for easy disassembly. The micro-arched design not only improves the structural stability of container 1, but also effectively prevents condensation. When the temperature reaches the dew point temperature, the arched design of the top of container 1 allows water droplets to flow out smoothly, preventing water droplets from accumulating on the equipment and thus ensuring the long-term stable operation of the equipment.

[0043] In addition, an air conditioner 7 is installed on the outside of container 1. The air outlet of the air conditioner 7 is connected to the inside of container 1. A deflector 9 is installed at the air outlet of the air conditioner 7. The deflector 9 is directed toward the copper busbar of the power cabinet 12. It can effectively blow cold air directly onto the copper busbar to help dissipate heat from the copper busbar, reduce the overheating of the equipment, and further improve the heat dissipation effect of the entire system, ensuring the good working condition of the power module 4 and other electronic components.

[0044] The container-type water-cooled reactive power compensation device incorporates multiple safety features to ensure equipment stability and lifespan. Firstly, all electrical connections utilize copper busbars, reducing contact resistance and ensuring smooth current flow. Secondly, the design of the water-cooling piping 5 ensures uniform coolant flow, preventing localized overheating. The slightly arched top cover of container 1 prevents dew point formation, avoiding moisture accumulation that could damage the equipment. Simultaneously, the airflow deflector 9 of the air conditioning system 7 precisely regulates airflow, ensuring cooling performance is unaffected by the external environment.

[0045] Example 2

[0046] In this embodiment, as Figure 5 As shown, a total of 57 power modules 4 are installed. Three power cabinets 12 are used within the 54 modules, with 18 power modules 4 arranged in each cabinet, layered in four rows. Within each cabinet 12, the power modules 4 are arranged sequentially from bottom to top in a pattern of 5, 5, 4, and 4. The two empty rows of power module 4 mounting positions on the top and second-to-top floors are placed in the column closest to the water-cooled control cabinet 6. This layout not only improves heat dissipation but also facilitates module management and maintenance.

[0047] In the power cabinet 12, the top two layers of power modules 4 in each column form a group, and the bottom two layers of power modules 4 form a group. The two power modules 4 in the same group are connected in series through capillary tubes 11. The bottom power module 4 in the same group is connected to the water inlet pipe through capillary tubes 11, and the top power module 4 is connected to the water outlet pipe through capillary tubes 11. Different groups are connected in parallel between the water inlet pipe and the water outlet pipe.

[0048] Example 3

[0049] In this embodiment, as Figure 6 As shown, a total of 57 power modules 4 are installed. For the power cabinet 12 with 51 modules, three power cabinets 12 are designed, with 17 power modules 4 arranged in each cabinet 12, in four layers. The power modules 4 in each cabinet 12 are arranged from bottom to top in a sequence of 5, 5, 4, and 3. The empty power module 4 mounting position on the second-to-last layer is placed in the column closest to the water-cooled control cabinet 6. The three power modules 4 on the top layer are placed in the center, and the two empty power module 4 mounting positions on the top layer are located in the columns on either side. This layout not only improves the heat dissipation effect but also facilitates the management and maintenance of the modules.

[0050] In the power cabinet 12, the top two layers of power modules 4 in each column form a group, and the bottom two layers of power modules 4 form a group. The two power modules 4 in the same group are connected in series through capillary tubes 11. The bottom power module 4 in the same group is connected to the water inlet pipe through capillary tubes 11, and the top power module 4 is connected to the water outlet pipe through capillary tubes 11. Different groups are connected in parallel between the water inlet pipe and the water outlet pipe.
