[0002] High-voltage filtering reactors are an indispensable part of the power system, mainly used to filter out harmonics in the power grid, stabilize voltage, and improve power quality. However, a large amount of heat is generated during the operation of high-voltage filtering reactors. Especially under the conditions of large current and high frequency, overheating will lead to a decline in the performance of the reactor and even damage. Therefore, an efficient heat dissipation system is crucial to ensure the stable operation of high-voltage filtering reactors.

[0003] The traditional heat dissipation methods of high-voltage filtering reactors mainly rely on natural cooling or simple forced air cooling. Natural cooling has low efficiency and cannot meet the heat dissipation requirements of high-power reactors, especially under high load and high ambient temperature. Although forced air cooling can improve the heat dissipation efficiency, the fixed position and direction of the fan may lead to uneven distribution of the heat dissipation area, forming heat dissipation blind spots and affecting the overall heat dissipation efficiency.

The combined use of the transmission assembly and the support assembly enables the working position of the heat dissipation fan blades 6 to be adjusted. This design makes the heat exchange air flow of the reactor body 1 change continuously, not only increasing the heat dissipation area but also reducing the heat dissipation blind area. The adoption of the installation base 2 and a plurality of groups of support members 3 provides additional mechanical stability, ensuring that the structure will not be damaged due to vibration or external force when the reactor operates in a high-voltage environment, extending the service life of the equipment, improving heat dissipation stability, and reducing the heat dissipation blind area.

[0027] As Figures 1 to 4As shown, as a preferred solution, the support assembly includes positioning slide rails 7 symmetrically arranged inside the cavity of the mounting base 2, and moving parts 8 are slidably arranged on two groups of positioning slide rails 7, and multiple groups of support parts 3 are arranged on the moving parts 8; the positioning slide rails 7 are symmetrically arranged inside the cavity of the mounting base 2, and form a sliding fit with the moving parts 8, which not only provides a more stable support basis for the heat dissipation fan blades 6, but also enhances the mechanical flexibility of the equipment. The multiple groups of support parts 3 on the moving parts 8 are connected to the transmission shaft 4, so that the heat dissipation fan blades 6 can change position with the sliding of the moving parts 8. This dynamic adjustment mechanism greatly improves the fluidity of the heat exchange airflow, effectively reduces the heat dissipation blind area, and ensures that the heat energy of the reactor body 1 under the high-voltage working state can be quickly and evenly dissipated.

Multiple groups of hollow shafts 10 are coaxially arranged and driven by the driving shaft 14, so that the synchronous operation of multiple groups of transmission shafts 4 is realized, and the coordination of all the heat dissipation fan blades 6 is ensured. The setting of the auxiliary part 15 provides additional support for the driving shaft 14.

[0029] like Figures 1 to 4As shown, as a preferred solution, the transmission assembly includes a connecting beam 16 arranged on the moving member 8, a transmission crankshaft 17 is arranged at the shaft hole of the connecting beam 16, a guide member 18 is arranged inside the cavity of the mounting base 2, the transmission crankshaft 17 is slidably arranged inside the guide groove of the guide member 18, and the transmission crankshaft 17 and the drive shaft 14 are transmitted through the connecting assembly, and the connecting assembly includes a worm 19 coaxially arranged on the drive shaft 14, a worm wheel 20 coaxially arranged on the transmission crankshaft 17, and the worm 19 is meshingly connected with the worm wheel 20; through the meshing transmission connection between the worm 19 and the worm wheel 20, the transmission from the drive shaft 14 to the transmission crankshaft 17 is realized.

The worm 19 and worm wheel 20 transmission has a self-locking feature, which can keep the current position of the cooling fan blades 6 unchanged even in the event of power outage or power source interruption, avoiding equipment damage or performance degradation caused by accidental movement. At the same time, the worm 19 and worm wheel 20 cooperate to form a speed reduction transmission.

[0030] like Figures 1 to 4 As shown, as a preferred solution, a filter 21 is provided at the through groove at the bottom end of the mounting base 2; the filter 21 can block external dust and impurities, effectively avoiding blockage of the heat dissipation channel or dust accumulation on the surface of the reactor due to particulate matter in the air, and ensuring that the equipment can still maintain good heat dissipation performance in harsh environments.

[0031] like Figures 1 to 4 As shown, as a preferred solution, support legs 22 are symmetrically arranged at both ends of the mounting base 2, and the support legs 22 support the mounting base 2 to detach from the mounting surface, and a plurality of fixing holes are arranged on the support legs 22; the design of the support legs 22 ensures that the reactor body 1 is firmly supported on the mounting surface, and the configuration of the plurality of fixing holes provides a plurality of installation options, thereby enhancing the installation flexibility and stability of the equipment; the design of the support legs 22 raises the mounting base 2, increases the air circulation space between the bottom of the reactor and the ground, is conducive to the formation of natural convection, and further optimizes the heat dissipation conditions of the reactor, which is particularly important, especially in high temperature or poorly ventilated environments.

[0033] When the reactor body 1 is connected to the high-voltage power supply and starts to work, heat is generated inside the reactor body 1. At this time, the drive motor 13 in the drive assembly receives the start signal and starts to operate. The output end of the drive motor 13 drives the drive shaft 14 to rotate. Through the cooperation between the drive shaft 14 and the multi-faceted inner holes of multiple hollow shafts 10, power is transmitted to the multiple hollow shafts 10. The driving bevel gears 11 on the hollow shafts 10 rotate accordingly, and the driven bevel gears 12 meshing with them transmit the power to the transmission shaft 4, thereby driving multiple groups of radiator fan blades 6 on the fixing member 5 to start rotating. At the same time, the worm 19 on the drive shaft 14 rotates. Through the meshing drive with the worm gear 20, the rotational motion is converted into the transmission crankshaft 17. The transmission crankshaft 17 slides in the diversion groove of the guiding member 18, converting the rotational motion into the linear motion of the transmission crankshaft 17, causing the working position of the radiator fan blades 6 to swing reciprocally. The airflow generated by the rotation of the radiator fan blades 6 passes through the heat dissipation channels around the reactor body 1, accelerating the flow of the heat exchange airflow, and effectively dissipating the heat generated by the reactor body 1 under the high-voltage working state to the surrounding environment.
