Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a water-cooled reactor which is convenient for water-cooling plate installation. Background Art

[0002] Reactor, also called inductor, is a widely used inductive component, mainly including upper iron yoke, iron core, AC working winding and lower iron yoke. The AC working winding is composed of wires wound on the iron core. As a reactive power compensation method, high-voltage arc-extinguishing reactor is indispensable in the power system. It can be used to limit the current impact caused by sudden voltage changes and operational overvoltage of the power grid, smooth the peak pulses contained in the power supply voltage, or smooth the voltage defects generated by the phase change of the bridge rectifier circuit, effectively protect the inverter and improve the power factor. It can not only prevent interference from the power grid, but also reduce the pollution of the harmonic current generated by the rectifier unit to the power grid.

[0003] The reactor generates a lot of heat during operation. To ensure the normal operation of the reactor and to dissipate heat quickly, water-cooled reactors have emerged that use water cooling to quickly dissipate heat. The water-cooled reactor in the prior art (such as the patent with publication number CN210837411U) has a water-cooling plate installed with the frame of the reactor by bolts. This has the following problems: threaded holes need to be drilled on the top water-cooling plate, and in order to ensure the sealing of the water-cooling plate, the cavity inside the water-cooling plate is reduced; this results in an increase in the weight of the top water-cooling plate, and at the same time, the reduction in the volume of the cavity of the top water-cooling plate will lead to a decrease in the water flow of the top water-cooling plate, thereby reducing the water cooling effect at the top of the reactor.

[0028] A second buckle plate 9 is provided in the middle of the side wall of the first buckle plate 7 , a first end of the second buckle plate 9 is rotatably connected to the first buckle plate 7 , and a second end of the second buckle plate 9 is provided with a second clamping hole 10 adapted to the clamping hook 6 .

[0029] The first mounting plate 4 is welded or bonded to the water cooling plate 2, and the second mounting plate 5 is welded or bonded to the reactor body 1. In this embodiment, the first mounting plate 4 and the second mounting plate 5 are both fixed by welding.

[0031] The second gusset plate 9 is a Japanese-shaped structure.

[0032] The connecting piece 3 is made of stainless steel.

[0033] Among them, 1. The specific structure of the water-cooling plate 2 is the existing technology, such as the patent with publication number CN210837411U, the vertically arranged water-cooling plate 2 is arranged between the winding and the iron core, and the horizontal (top) water-cooling plate 2 is arranged on the top of the reactor. 2. In order to ensure the fixing effect of the water-cooling plate 2, there are at least two connecting members 3. When two connecting members 3 are arranged, they are symmetrically arranged on two opposite side walls of the water-cooling plate 2.

[0034] When the water-cooling plate 2 is installed, the top water-cooling plate 2 is fixed when the vertical water-cooling plate 2 is installed in place to complete the fixing of the entire water-cooling plate 2. The specific process is: the bottom of the water-cooling plate 2 is fitted with the top of the reactor, and the first mounting plate 4 and the second mounting plate 5 are located in the same straight line.

[0035] Then, the second buckle plate 9 is rotated to make the hook 6 snap into the second snap hole 10 of the second buckle plate 9. After the hook 6 and the second snap hole 10 are in place, the first buckle plate 7 is rotated to make the buckle part 8 enter the first snap hole of the first buckle plate 7. At this time, the second buckle plate 9 is kept in a vertical tension state. The bolts are screwed into the threaded holes 11 to complete the limiting of the first buckle plate 7 and the fixing of the water cooling plate 2.

[0036] The water-cooling plate 2 of the utility model is connected to the reactor body 1 through the connecting piece 3, and there is no need to drill the threaded hole 11 on the top water-cooling plate 2, so the volume of the internal cavity of the water-cooling plate 2 can be guaranteed, the water flow of the top water-cooling plate 2 can be guaranteed, the heat exchange area during water cooling can be increased, and the water cooling effect can be guaranteed.

The heat in the heat-conducting copper tube is transferred to the heat-conducting plate for concentration. The heat on the heat-conducting plate is blown away by the cooling fan for dissipation, thereby reducing the temperature of the circulating cooling water and improving the cooling effect of the cooling water circulating liquid cooling.
