Description

Technical Field

[0001] This utility model relates to the field of power technology, and more specifically, to an IGCT converter valve module. Background Technology

[0002] Flexible DC converter valves serve as a bridge between AC and DC power grids, possessing rectification, inversion, or switching functions. Their rapid controllability allows for quick operation of DC power transmission startup and shutdown.

[0003] Currently, most converter valves adopt an IGBT-based topology. This design results in a relatively dispersed layout, and under high voltage and high current conditions, multiple IGBTs are typically required in series and parallel, leading to increased size and cost. Some converter valves use IGCT converter valves, which can significantly reduce the size of flexible DC converter valves at the same voltage level, saving costs and making them more suitable for flexible DC converter valve design applications. However, most IGCT converter valves are fixed structures that cannot be moved, and the power supply module and control module are separately installed, resulting in a large footprint and low structural compactness. When some modules fail, it is difficult to quickly identify the fault location, requiring separate disassembly for repair, which is time-consuming and labor-intensive. Prolonged repairs can also lead to partial equipment failure and even significant economic losses. In addition, conventional converter valve modules are themselves very heavy, making them difficult to move. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an IGCT converter valve module that uses IGCT devices, has a small size and compact structure, and has maintenance pulleys at the bottom of the module for easy maintenance.

[0005] The present invention adopts the following technical solution.

[0006] This utility model discloses an IGCT converter valve module, which includes: a module fixing frame, a module controller, a power supply, a bypass contactor, a main switch valve string, a supporting capacitor, a fixing bracket, and guide wheels.

[0007] The module fixing frame is connected in series with the main switch valve and is connected to the support capacitor through the fixing bracket.

[0012] Preferably, the module fixing frame includes: a controller fixing plate, one end of which is connected to the first vertical plate, and the module controller is connected to the controller fixing plate so that the module controller is fixed on the module fixing frame.

[0013] Preferably, the module fixing frame further includes: a power fixing plate, which is connected to the main switch valve string, and the power supply is connected to the power fixing plate, so that the power supply is fixed on the main switch valve string.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The embodiments described in this application are merely some embodiments of this utility model, not all embodiments. Based on the spirit of this utility model, other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of this utility model.

[0029] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] like Figures 1-8As shown, this utility model discloses an IGCT converter valve module, which includes: a module fixing frame 1, a main switch valve string 5, a supporting capacitor 6, a fixing bracket 7, and guide wheels;

[0032] The module fixing frame 1 is internally connected to the main switch valve string 5 and connected to the supporting capacitor 6 through the fixing bracket 7. Multiple guide wheels are provided at the bottom of the module fixing frame 1. The module controller 2, power supply 3 and bypass contactor 4 are all located inside the module fixing frame 1.

[0033] Guide wheels enable the module fixing frame 1 to move synchronously with the main switching valve string 5 and the supporting capacitor 6, forming an integrated moving and operating structure. This facilitates the rapid movement and replacement of the entire converter valve module during maintenance, avoiding the need for separate disassembly and repair due to partial damage to the converter valve, which is time-consuming and can lead to partial equipment failure and inoperability. Overall replacement saves time and effort, allowing maintenance without affecting equipment operation. Simultaneously, the module fixing frame 1 integrates the power supply, control, and main functions of the converter valve module into a single structure, maximizing structural compactness and ease of use, reducing floor space, ensuring safe and reliable connections, and saving operation and maintenance time.

[0034] It is understandable that this utility model adopts the topology of domestic IGCT devices. Using IGCT devices in flexible DC converter valves can reduce the number of devices used under the same voltage level and current, thereby significantly reducing the size of the flexible DC converter valve. At the same time, it saves material costs economically and is more suitable for the design and application of flexible DC converter valves.

[0035] The IGCT converter valve module further includes a module controller 2, a power supply 3, and a bypass contactor 4. The module controller 2, the power supply 3, and the bypass contactor 4 are all located in the module fixing frame 1 at the front position corresponding to the main switch valve string 5, realizing the integration of the power supply, control, and main functions of the converter valve module into an integrated structure, improving the structural compactness and ease of use, reducing the floor space, and saving operation and maintenance time.

[0036] The module fixing frame 1 includes: a base plate 1-1, a first vertical plate 1-2, a top plate 1-3, a second vertical plate 1-4, and a third vertical plate 1-5. The first vertical plate 1-2, the second vertical plate 1-4, and the third vertical plate 1-5 are arranged sequentially at the front ends of the base plate 1-1. The upper ends of all the vertical plates are connected to the top plate 1-3. The base plate 1-1 has a door-shaped structure with a sliding groove inside. The supporting capacitor 6 is inserted into the rear part of the sliding groove and connected to the base plate 1-1. The main switch valve string 5 is inserted into the middle part of the sliding groove and connected to the base plate 1-1. The rear end of the top plate 1-3 is connected to the fixing frame 7. The other end of the fixing frame 7 is connected to the top of the supporting capacitor 6. The base plate 1-1 and the top plate 1-3 achieve double vertical fixation of the supporting capacitor 6. At the same time, the inner wall of the sliding groove on the base plate 1-1 fixes the supporting capacitor 6 and the main switch valve string (5) laterally, making the connection between the supporting capacitor 6 and the module fixing frame 1 more stable and preventing it from falling off and shaking during movement or operation.

[0037] The module fixing frame 1 also includes: a controller fixing plate 9, one end of which is connected to the first vertical plate 1-2, and the module controller 2 is connected to the controller fixing plate 9, so that the module controller 2 is fixed on the module fixing frame 1 for controlling the operation of the IGCT converter valve module.

[0038] The module fixing frame 1 also includes a power fixing plate 8, which is connected to the upper front end of the main switch valve string 5. The power supply 3 is connected to the power fixing plate 8, so that the power supply 3 is fixed on the main switch valve string 5 and is used to supply power to the module controller 2, bypass contactor 4, main switch valve string 5, etc.

[0039] The lower end of the bypass contactor 4 is connected to the lower side of the base plate 1-1.

[0040] The main switch valve string 5 is connected to the supporting capacitor 6 on one side and the first input / output copper busbar 10 is set on the other side. The bypass contactor 4 is equipped with the second input / output copper busbar 11 at the upper end. The first input / output copper busbar 10 and the second input / output copper busbar 11 are attached to each other and connected by the height difference, which saves horizontal space, improves the compactness of the structure, is easy to replace, and simplifies the installation.

[0041] The beneficial effect of this utility model is that, compared with the prior art,

[0042] This utility model integrates the power supply, control, and main functions of the converter valve module into a single structure using a modular fixing frame. Utilizing the height difference maximizes structural compactness and ease of use, reduces floor space, ensures safe and reliable connections, and saves operation and maintenance time. Furthermore, it allows for movement, operation, maintenance, and installation as a whole, simplifying the usage process and reducing labor and time costs. Simultaneously, the pulley system facilitates the movement, maintenance, and replacement of the converter valve module. Moving the module as a whole allows for rapid replacement, quickly restoring operational functionality and avoiding the excessively long maintenance time and operational failures caused by separate disassembly. Overall replacement saves time and effort.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of this utility model. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model should be covered within the protection scope of the claims of this utility model.
