All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1-6, an embodiment of the present disclosure provides an intelligent small-sized extraction-type power compensation cabinet, which includes a compensation cabinet body 1, wherein the compensation cabinet body 1 is provided with a plurality of vertically arranged drawer groups. In some embodiments, the number of drawer sets is three. In other embodiments, the number of drawer groups may be set to four groups or five groups, etc., depending on the actual situation. Each drawer group comprises a first drawer 2 in an L shape and a second drawer 3 in an inverted L shape, a first capacitance compensation device box body 4 is arranged in the first drawer 2, and a second capacitance compensation device box body 5 is arranged in the second drawer 3. Each drawer can be pulled apart individually. Wherein, first drawer 2 has first horizontal chamber 6 and first vertical chamber 7, and second drawer 3 has second horizontal chamber 8 and second vertical chamber 9, and first drawer 2 and second drawer 3 transversely set up side by side, and second horizontal chamber 8 is located first horizontal chamber 6 top, and first vertical chamber 7 is located the side in second horizontal chamber 8, and second vertical chamber 9 is located the side in first horizontal chamber 6. Simultaneously, first fan 10 is installed to the roof in first vertical chamber 7, and first air inlet 11 that vertically runs through to the bottom of first drawer 2 in the top drawer group is seted up at the top in first vertical chamber 7, and first air outlet 12 has been seted up to the preceding lateral wall that first horizontal chamber 6 kept away from first vertical chamber 7, and first capacitance compensation arrangement box 4 sets up between first air outlet 12 and the first air inlet hole that is located the diapire, is located the first air inlet 11 intercommunication to the atmosphere of top drawer group. The second fan 13 is installed to the diapire in the vertical chamber 9 of second, and the diapire in the vertical chamber 9 of second is offered and is vertically run through to the second income wind hole 14 at the second drawer 3 top in the bottom drawer group, and the preceding lateral wall that the vertical chamber 9 of second was kept away from to the horizontal chamber 8 of second has been offered second air outlet hole 15, and second capacitance compensation arrangement box 5 sets up between second air outlet hole 15 and the second income wind hole that is located the roof, is located the second income wind hole 14 intercommunication to the atmosphere of bottom drawer group.
In use, the first fan 10 in the topmost first drawer 2 draws air from the atmosphere, through the first air inlet aperture 11 and into the topmost first drawer 2. The air entering the first drawer 2 sequentially passes through the first vertical cavity 7 and the first horizontal cavity 6 of the first drawer 2, and finally flows out from the first air outlet hole 12 of the first drawer 2, so as to cool the first capacitance compensation device box 4 in the first drawer 2. Meanwhile, part of air which does not pass through the first capacitance compensation device box 4 is driven by the first fan 10 in the first drawer 2 at the bottom layer, and is pumped into the first drawer 2 at the bottom layer from the first air inlet 11 at the bottom. Air drawn into the bottom layer of first drawers 2 sequentially passes through the first vertical cavity 7 and the first horizontal cavity 6 of the first drawers 2, and finally flows out from the first air outlet holes 12 to cool the first capacitance compensation device box 4 in the bottom layer of first drawers 2. And so on, the first capacitance compensation device boxes 4 in all the first drawers 2 are cooled. Similarly, the second fan 13 in the second drawer 3 at the bottommost draws air from the atmosphere, and the air is drawn into the second drawer 3 at the bottommost layer after flowing through the second air inlet hole 14, sequentially passes through the second vertical cavity 9 and the second horizontal cavity 8 of the second drawer 3, and finally flows out from the second air outlet hole 15 of the second drawer 3, so as to cool the second capacitance compensation device box 5 in the second drawer 3. Meanwhile, part of air which does not pass through the second capacitance compensation device box 5 is driven by the second fan 13 in the first layer of second drawers 3 at the top, and is pumped into the first layer of second drawers 3 at the top from the second air inlet holes 14 at the top. Air drawn into the top layer of second drawers 3 sequentially passes through the second vertical cavity 9 and the second horizontal cavity 8 of the second drawers 3 and finally flows out of the second air outlet holes 15 of the second drawers 3 so as to cool the second capacitance compensation device box 5 in the top layer of second drawers 3. And so on, the second capacitance compensation device boxes 5 in all the second drawers 3 are cooled.
In the above process, since the first capacitance compensation device case 4 is disposed between the first air outlet hole 12 and the first air inlet hole located in the bottom wall, and the first air inlet hole 11 is connected to the bottom of the first vertical cavity 7 of the top first drawer 2, the air flowing into the first drawer 2 is the air in the top layer of the first drawer 2 that is not heated by the first capacitance compensation device case 4. Similarly, the air flowing into the second drawer 3 is the air in the bottom layer of the second drawer 3 which is not heated by the first capacitance compensation device case 4. The air temperature is relatively low, so that the cooling performance is ensured. Meanwhile, as only the first drawers 2 are vertically communicated in sequence and only the second drawers 3 are vertically communicated in sequence, all drawers are not communicated, the number of drawers through which air flows can not be too large, and the air temperature flowing into the corresponding drawers can not be too high. Simultaneously, for arranging two rows of drawers in parallel, the L-shaped first drawer 2 and the inverted L-shaped second drawer 3 are combined, so that the width of the whole intelligent small-sized extraction type power supply compensation cabinet can be effectively reduced while the heat dissipation structure is met, and the occupied volume is reduced.
In some embodiments, as shown in fig. 1 and 2, the bottom wall of the compensating cabinet body 1 is arranged on the ground in an overhead manner, and the second air inlet hole 14 located in the bottommost drawer group is communicated to the atmosphere from the bottom wall of the compensating cabinet body 1.

When air flows to the first air guiding circular bead 17 and the second air guiding circular bead 18, the air deflects under the guiding action of the first air guiding circular bead 17 and the second air guiding circular bead 18, and the air flowing direction is respectively towards the first air outlet hole 12 and the second air outlet hole 15, so that vortex is avoided, and the fluidity and the heat dissipation performance of the air are ensured.
In some embodiments, as shown in fig. 3 and 4, a first installation cavity 19 is provided at the top end of the first vertical cavity 7, the first fan 10 is installed in the first installation cavity 19, the first air inlet 11 is located at the top wall of the first installation cavity 19, and the bottom wall of the first installation cavity 19 is provided with a first communication hole 20 communicated to the first vertical cavity 7. The air enters the first vertical cavity 7 through the first communication hole 20 after entering the first installation cavity 19 from the first air inlet hole 11 under the driving of the first fan 10. Similarly, a second installation cavity 21 is arranged at the bottom end of the second vertical cavity 9, the second fan 13 is installed in the second installation cavity 21, the second air inlet 14 is located at the bottom wall of the second installation cavity 21, and a second communication hole 22 communicated to the second vertical cavity 9 is formed in the top wall of the second installation cavity 21. The air enters the second installation cavity 21 from the second air inlet hole 14 and then enters the first vertical cavity 7 through the second communication hole 22 under the driving of the second fan 13. The above arrangement allows the first fan 10 and the second fan 13 to be located in separate spaces, preventing possible malfunctions from affecting the first capacitance compensation device housing 4 and the second capacitance compensation device housing 5. At the same time, the top wall of the first vertical cavity 7 is detachably mounted on the first drawer 2, and the top wall of the second mounting cavity 21 is detachably mounted on the second drawer 3. The two can be detached by adopting the modes of bolt connection, plug-in connection or buckle connection and the like. To facilitate the disassembly, assembly and maintenance of the first fan 10 and the second fan 13.
In some embodiments, as shown in fig. 1 and 2, the bottom of the compensation cabinet body 1 is provided with feet 23 to overhead the bottom wall of the compensation cabinet body 1 from the ground. Meanwhile, the leg 23 is provided with a lifting roller 24, and the lifting roller 24 is lifted to be higher or lower than the bottom end of the leg 23. When the compensation cabinet body 1 needs to be moved, the lifting roller 24 extends downwards to be lower than the bottom ends of the supporting legs 23, so that the whole compensation cabinet body 1 is overhead and convenient to move. When the position of the compensation cabinet body 1 is fixed, the lifting roller 24 is retracted upwards to be higher than the bottom end of the supporting leg 23, so that the supporting leg 23 is contacted with the ground, and the lifting roller 24 is separated from the ground, so that the compensation cabinet body 1 is prevented from moving.
As shown in fig. 7, the lifting roller 24 includes a vertical slide rail 25, a roller 26, and a driving motor 27, and the vertical slide rail 25 and the driving motor 27 are connected with the support legs 23. The vertical slide rail 25 has a slide groove 28 with a polygonal cross section. In some embodiments, the chute 28 is rectangular in cross-section. In other embodiments, the chute 28 may also be hexagonal or octagonal in shape, etc.
The side wall of the chute 28 is provided with a vertical through notch 29, the roller 26 is positioned outside the vertical slide rail 25, and the roller 26 is provided with a sliding block 30 which extends into the chute 28 and matches the section of the chute 28. In some embodiments, the cross-sectional shape of slider 30 is also quadrilateral. The output end of the driving motor 27 is connected with a vertical screw 31 which is screwed through the sliding block 30. When the roller 26 needs to be lowered, the driving motor 27 drives the vertical screw 31 to rotate, the sliding block 30 cannot rotate under the limitation of the sliding groove 28, and the sliding block 30 moves downwards to drive the roller 26 to be lowered to be abutted against the ground. When the roller 26 needs to be lifted, the driving motor 27 reversely drives the vertical screw 31 to rotate, and the sliding block 30 moves upwards to drive the roller 26 to lift and separate from the ground.
In some embodiments, as shown in fig. 1 and 2, a protective cover 32 is elastically connected to the top of the compensation cabinet body 1. To prevent falling objects. The protection casing 32 is connected with the top elasticity of compensation cabinet body 1, and when having the junk to hit protection casing 32, its impact force can attenuate under elastic connection's effect, avoids first capacitance compensation device box 4 and second capacitance compensation device box 5 in the compensation cabinet body 1 to receive too big impact. Specifically, an elastic member 33 is further included, and the elastic member 33 is preferably a spring. In other embodiments, spring pieces and other elastic components can be used. The protective cover 32 is connected with the top wall of the compensating cabinet body 1 through an elastic piece 33.
