Description

Technical Field

[0001] This utility model relates to the field of reactive power regulator technology, specifically an energy-saving high-voltage SVG dynamic reactive power regulator. Background Technology

[0002] In modern power systems, high-voltage SVG dynamic reactive power regulators, with their efficient dynamic compensation capability for reactive power, have become key equipment for ensuring power quality and improving the stability of power systems.

[0003] However, the power devices inside the high-voltage SVG dynamic reactive power regulator generate a large amount of Joule heat during high-frequency switching and high-current flow, resulting in high overall energy consumption and severe heat accumulation. Traditional heat dissipation components are unable to quickly remove such a large amount of heat when faced with such a high heat load. Increasing the number of heat dissipation components or increasing their power will consume a considerable amount of electrical energy to improve heat dissipation. This additional energy consumption will divert the power resources originally used for reactive power regulation, thereby affecting the regulation efficiency of the reactive power regulator and causing a decrease in the accuracy of reactive power compensation to the power grid. Therefore, there is an urgent need for an energy-saving high-voltage SVG dynamic reactive power regulator to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an energy-saving high-voltage SVG dynamic reactive power regulator to solve the problem mentioned in the background art that the traditional heat dissipation components have a poor heat dissipation effect when encountering reactive power regulators with large heat, and that the large energy consumption generated by the heat dissipation components when the number or power of the heat dissipation components is increased in order to improve the heat dissipation effect may affect the regulation efficiency of the reactive power regulator.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving high-voltage SVG dynamic reactive power regulator, comprising a main frame, wherein a heat dissipation component is provided inside the main frame;

[0006] The heat dissipation assembly includes two mounting brackets, both of which are fixedly connected to the inner sides of the main frame. Multiple rotating columns are rotatably connected to the inner wall of each mounting bracket. A cooling fan is fixedly connected to the surface of each rotating column, and a connecting bracket is fixedly connected to the surface of each rotating column. Two movable columns are rotatably connected to the inner wall of each mounting bracket. Multiple toothed grooves are formed on the surface of each connecting bracket, and spur gears are fixedly connected to the surface of each movable column. The surfaces of the spur gears are all meshed with the multiple toothed grooves.

[0007] Preferably, a synchronous pulley is fixedly connected to the surface of each of the two movable columns, and a synchronous belt is fitted onto the surface of each of the two synchronous pulleys.

[0008] Preferably, a drive column is rotatably connected to the inner wall of the main frame, and drive wheels are fixedly connected to the surface of the upper movable column and the surface of the drive column, with the same belt sleeved on the surface of the two drive wheels.

[0009] Preferably, a first bearing is fixedly connected to the surface of the rotating column, and the surfaces of multiple first bearings are fixedly connected to the inner wall of the mounting bracket.

[0010] Preferably, a second bearing is fixedly connected to the surface of the movable column, and the inner walls of the two second bearings are fixedly connected to the inner wall of the mounting frame.

[0011] Preferably, a motor is fixedly connected to the side wall of the main frame, and the surface of the drive column is fixedly connected to the output end of the motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The heat dissipation components allow the rotating columns to drive the spur gear, which in turn interacts with the toothed grooves on the surfaces of multiple connecting frames to drive multiple rotating columns to rotate synchronously. This synchronous rotation of the columns drives multiple cooling fans to rotate synchronously, exchanging heat with the air inside the main frame and facilitating heat dissipation. Furthermore, the heat dissipation components also allow the motor's output to drive the two rotating columns synchronously, further improving heat dissipation while reducing energy consumption and saving electrical resources. This prevents the high energy consumption of the heat dissipation components from negatively impacting the efficiency of the reactive power regulator. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This utility model provides an energy-saving high-voltage SVG dynamic reactive power regulator, including a main frame 1. A heat dissipation assembly 2 is installed inside the main frame 1. The heat dissipation assembly 2 includes two mounting brackets 201, both fixedly connected to the inner sides of the main frame 1. Multiple rotating columns 203 are rotatably connected to the inner wall of each mounting bracket 201. Cooling fans 204 are fixedly connected to the surface of each rotating column 203, and connecting brackets 205 are fixedly connected to the surface of each rotating column 203. Two movable columns 207 are rotatably connected to the inner wall of each mounting bracket 201, and the connecting brackets 205... The surface of the movable column 207 has multiple toothed grooves 208. The surface of the movable column 207 is fixedly connected to a spur gear 209. The surface of the spur gear 209 is meshed with the multiple toothed grooves 208. Through the heat dissipation component 2, the rotation of the movable column 207 can drive the spur gear 209 to rotate. The rotation of the spur gear 209 can drive the multiple rotating columns 203 and the cooling fan 204 to rotate synchronously. This facilitates heat dissipation of the interior of the main frame 1 while reducing energy consumption and saving electrical energy resources. It also avoids the impact of the high energy consumption of the heat dissipation component 2 on the regulation efficiency of the reactive power regulator.

[0022] Furthermore, a synchronous wheel 210 is fixedly connected to the surface of each of the two movable columns 207, and a synchronous belt 211 is fitted onto the surface of each of the two synchronous wheels 210. By using the synchronous wheels 210 and the synchronous wheel 210 in cooperation with each other, the rotation of the upper movable column 207 can drive the lower movable column 207 to rotate synchronously.

[0023] Furthermore, a drive column 212 is rotatably connected to the inner wall of the main frame 1. Drive wheels 213 are fixedly connected to the surface of the upper movable column 207 and the surface of the drive column 212. The same belt 214 is sleeved on the surface of the two drive wheels 213. The drive wheels 213 and the belt 214 cooperate with each other so that the rotation of the drive column 212 can drive the upper movable column 207 to rotate.

[0024] Furthermore, a first bearing 202 is fixedly connected to the surface of the rotating column 203. The surfaces of multiple first bearings 202 are fixedly connected to the inner wall of the mounting frame 201. The first bearings 202 facilitate the positioning of the rotating column 203 and facilitate its rotation, thereby reducing the friction between the rotating column 203 and the mounting frame 201 when it rotates.

[0025] Furthermore, a second bearing 206 is fixedly connected to the surface of the movable column 207. The inner walls of the two second bearings 206 are fixedly connected to the inner wall of the mounting bracket 201. The second bearings 206 facilitate positioning and rotation.

[0026] Furthermore, a motor 215 is fixedly connected to the side wall of the main frame 1, and the surface of the drive column 212 is fixedly connected to the output end of the motor 215. By using the motor 215, the output end of the motor 215 can rotate to drive the drive column 212 to rotate.

[0027] Working principle: The heat dissipation component 2 causes the output end of the motor 215 to rotate, driving the drive column 212 to rotate. The rotation of the drive column 212 drives the upper movable column 207 to rotate through the interaction of the drive wheel 213 and the belt 214. The rotation of the upper movable column 207 drives the lower movable column 207 to rotate synchronously through the interaction of the synchronous pulley 210 and the synchronous belt 211. When the movable column 207 rotates, it drives the spur gear 209 to rotate. The rotation of the spur gear 209 is achieved by the tooth grooves 20 on the surface of the multiple connecting brackets 205. The 8 components work together to drive multiple rotating columns 203 to rotate synchronously. The synchronous rotation of multiple rotating columns 203 drives multiple cooling fans 204 to rotate synchronously, which exchanges heat with the air inside the main frame 1, thus facilitating heat dissipation inside the main frame 1. At the same time, through the heat dissipation component 2, the output end of the motor 215 can rotate to drive multiple cooling fans 204 to rotate synchronously, thus facilitating heat dissipation inside the main frame 1 while reducing energy consumption, saving electrical energy resources, and avoiding the impact of high energy consumption of the heat dissipation component 2 on the regulation efficiency of the reactive power regulator.
