Description
Technical field
The utility model relates to a kind of cooling structure for water cooling reactor or transformer, electric power system and element thereof.
Background technology
Reactor is one of critical elements in electric power system, and its type of cooling is divided into that nature is cold, air-cooled, water-cooled three kinds, and the type of cooling is that the reactor of water-cooled is referred to as water cooling reactor.
As shown in Figure 1, existing a kind of water cooling reactor comprises tri-phase iron core 1, three components is not wound on coil 2a, 2b, 2c on every phase iron core 1 and cooling structure 3, and cooling structure 3 can take away by carrying out heat exchange with iron core 1, coil 2a, 2b, 2c the heat that reactor work produces.
Shown in composition graphs 2, cooling structure 3 comprises distributor 5,12 coldplates 4,16 pipelines 6.Wherein, distributor 5 is fixed on upper yoke 7.12 coldplates 4 divide equably and are placed in coil 2a, 2b, 2c, and four coldplates 4 in coil 2a, 2b, 2c divide the two ends being placed on every phase iron core 1 equably, and namely the often end of every phase iron core 1 is provided with two coldplates 4.
In conjunction with reference to figure 3, general export 9, two the first cooling passages 10 cannot seen in the first cooling passage 10 that distributor 5 is provided with main entrance 8, general export 9, four is all communicated with main entrance 8 and four the second cooling passages 11, figure be all communicated with general export 9 and two the second cooling passages 11 represented by dashed line.
As shown in Figure 4, coldplate 4 is provided with U-shaped cooling passage, because this U-shaped cooling passage is positioned at the inside of coldplate 4, therefore cannot show complete in the drawings, only can show import 12 and the outlet 13 of this U-shaped cooling passage.
Shown in composition graphs 1 to Fig. 2, distributor 5 and 12 coldplates 4 are connected into four cooling branch roads by 16 connecting tubes 6, and the coldplate 4 in cooling route first cooling passage 10, coil 2a described in every bar, the coldplate 4 in coil 2b, coldplate 4, second cooling passage 11 in coil 2c are in series successively by the flow direction (in figure shown in arrow) of connecting tube 6 according to cooling fluid.Three coldplates 4 cooled described in every bar on branch road are positioned at same one end of iron core 1, and all near iron core 1 or all away from iron core 1.The cooling fluid flowed into from distributor 5 main entrance 8 is taken away along four described cooling bypass flow with heat reactor work produced respectively, and the cooling fluid flowed out from four described cooling branch roads flows out from distributor 5 general export 9.
But above-mentioned existing water cooling reactor has the following disadvantages:
1) cooling effect of cooling structure 3 is not good, reason is: on the one hand, cooling fluid is after the main entrance 8 of distributor 5 flows into, just flow out from the general export 9 of distributor 5 after successively need flowing through three coldplates be cascaded 4, cooling fluid can heat up because of the heat of soaking reactor generation when flowing through the coldplate 4 of upstream, and the coldplate 4 of the absorbent heat upstream relative when flowing through the coldplate 4 in downstream of the cooling fluid after intensification reduces, on the other hand, coldplate 4 forms by processing U-shaped cooling passage in raw material plate, distributor 5 is by processing main entrance 8 in raw material plate, general export 9, first cooling passage 10, second cooling passage 11 forms, in order to ensure U-shaped cooling passage, main entrance 8, general export 9, first cooling passage 10, second cooling passage 11 can process smoothly in raw material plate, coldplate 4 is at the minimum wall thickness (MINI W.) of corresponding U-shaped cooling passage position, distributor 5 is in corresponding main entrance 8, general export 9, first cooling passage 10, the minimum wall thickness (MINI W.) of the second cooling passage 11 position arranges larger, cause coldplate 4, the radiating effect of distributor 5 is poor, rapidly heat that reactor produces can not be distributed.
2) be used for manufacturing coldplate 4, the raw material versatility of distributor 5 is not strong, reason is: known as mentioned above, coldplate 4, distributor 5 is all utilize raw material plate to process, and the width of coldplate 4 is determined according to the width of iron core 1, the width of distributor 5 is determined according to the quantity of coldplate 4 in cooling structure 3, therefore, according to iron core 1 width, the difference of coldplate 4 quantity, be used for manufacturing coldplate 4, the raw material plate dimensions of distributor 5 is different, namely the versatility of raw material plate is not strong, significant limitation can be there is when finding suitable raw material plate, too increase coldplate 4, the manufacturing cost of distributor 5.
3) cooling structure 3 takes up room comparatively large, and reason is: on the one hand, and 16 connecting tubes 6 are all bendings, take up room larger; On the other hand, each cooling branch road in need to utilize two connecting tubes 6 to be cascaded by three coldplates 4, cause connecting tube 6 quantity in cooling structure 3 more, take up room larger.
