Description

Technical Field

[0001] The present invention relates to the technical field of box-type transformers, and in particular to a box-type transformer with an interlayer pipe air cooling function. Background Art

[0002] A box-type transformer (abbreviated as "box-type transformer") is a prefabricated substation or substation. It combines high-voltage switchgear, transformers, and low-voltage distribution equipment according to a specific wiring scheme, all housed within a single box. Box-type transformers are particularly well-suited for urban power grid construction and renovation, representing a new type of substation, following the rise of civil substations. Since their introduction, box-type transformers have experienced rapid development, and with the continuous upgrading and renovation of urban distribution networks, they have become widely used.

[0003] The transformer and electrical equipment inside the box-type transformer generate a large amount of heat during operation. Currently, the heat dissipation method for box-type transformers is passive heat dissipation, that is, heat dissipation and cooling are carried out through heat dissipation holes. This heat dissipation method is not effective. In high-temperature outdoor areas, this heat dissipation method cannot ensure that the box-type transformer is in a normal temperature environment, which can easily lead to operational failures of the box-type transformer.

[0035] In addition, the box-type transformer with interlayer pipe air cooling function also includes a third through-tube 220 and a fourth through-tube 230; the outer side plate 120 includes a first side plate 130, a second side plate, a third side plate and a fourth side plate connected in sequence; the inlet end of the air-cooling pipe 140 is connected to the third through-tube 220; the outlet end of the air-cooling pipe 140 is connected to the fourth through-tube 230; the third through-tube 220 and the fourth through-tube 230 are both arranged in the first side plate 130; the first blower 260 and the second blower 270 are both arranged on the outer wall of the first side plate 130; the third through-tube 220 is connected to the outlet end of the first blower 260; the fourth through-tube 230 is connected to the inlet end of the second blower 270.

[0037] In addition, the support frame 280 includes a first support plate 310 and a second support plate 320 that are parallel to each other and both arranged vertically, as well as a first transverse plate 330 and a second transverse plate 340 that are parallel to each other and both arranged horizontally. The first support plate 310 is fixed to the outer wall of the first side plate 130. The two sides of the first transverse plate 330 are respectively connected to the top of the first support plate 310 and the top of the second support plate 320. The two sides of the second transverse plate 340 are respectively connected to the bottom of the first support plate 310 and the bottom of the second support plate 320. A horizontal partition 420 is provided between the first support plate 310 and the second support plate 320. The first transverse plate 330, the partition 420, the first support plate 310, and the second support plate 320 enclose a cavity 360 with open ends. The heat exchange hollow plate 390 is disposed in the cavity 360. This embodiment improves the structure and features of the support frame 280.

[0038] At the same time, the axial fan 290 is connected to the outer wall of the first side plate 130, and the axial fan 290 is close to the open end of the cavity 360; the wind direction of the axial fan 290 is parallel to the first side plate 130; the cooling component also includes a fifth through-tube 370 and a sixth through-tube 380; the heat exchange hollow plate 390 is arranged vertically, and the interior of the heat exchange hollow plate 390 is hollow; the two ends of the fifth through-tube 370 are respectively connected to the first support plate 310 and the second support plate 320, and the two ends of the sixth through-tube 380 are respectively connected to the first support plate 310 and the second support plate 320; the two ends of the fifth through-tube 370 are closed, and the two ends of the sixth through-tube 380 are closed; the two ends of the heat exchange hollow plate 390 are respectively connected to the fifth through-tube 370 and the sixth through-tube 380; the interior of the heat exchange hollow plate 390 is respectively connected to the fifth through-tube 370 and the sixth through-tube 380.

[0039] Specifically, the fifth duct 370 and the sixth duct 380 are parallel to each other and are both horizontally arranged; the fifth duct 370 is perpendicular to the first support plate 310; the third duct 220 is higher than the fourth duct 230, and the first blower 260 is higher than the second blower 270; the first duct 240 and the second duct 250 are both vertically arranged; the top of the first duct 240 is connected to the inlet end of the first blower 260, and the bottom of the second duct 250 is connected to the outlet end of the second blower 270; the fifth duct 370 is closer to the axial fan 290 than the sixth duct 380; the first duct 240 passes through the first horizontal plate 330, and the bottom of the first duct 240 is connected to the fifth duct 370; the second duct 250 passes through the second horizontal plate 340, and the top of the second duct 250 is connected to the sixth duct 380.

[0040] Through the above technical solution, the circulation channel of air cooling flow is improved; specifically: first blower 260-third pipe 220-air cooling pipe-fourth pipe 230-second blower 270-second pipe 250-sixth pipe 380-heat exchange hollow plate 390-fifth pipe 370-first pipe 240-first blower 260.

[0041] In addition, the box-type transformer with interlayer pipe air cooling function also includes an atomization component; the atomization component includes a water pump (not shown), a water storage tank 350, a water outlet pipe 410, a first rotating shaft 440, a motor 670 and a first striking blade 450; a first annular plate 430 is provided on the upper surface of the partition 420, and the first annular plate 430 is perpendicular to the partition 420; the first rotating shaft 440 is sealed and rotated through the partition 420; the first rotating shaft 440 is perpendicular to the partition 420; the first rotating shaft 440 and the first annular plate 430 share a central axis; the upper part of the first rotating shaft 440 is in the first annular plate 430, and the first striking blade 450 is connected to the upper part of the first rotating shaft 440; the first annular plate 430 is located below the heat exchange hollow plate 390; the lower part of the first rotating shaft 440 is located below the partition 420; the motor 670 is used to drive the first rotating shaft 440 to rotate; the water tank 350 and the water pump are both arranged on the upper surface of the first horizontal plate 330, the inlet end of the water pump is connected to the external water source, and the outlet end of the water pump is connected to the water tank 350; the top of the water outlet pipe 410 is connected to the water tank 350, and the water outlet pipe 410 is arranged in the first horizontal plate 330; the water outlet pipe 410 is arranged vertically, and the bottom outlet of the water outlet pipe 410 faces the first annular plate 430; the water tank 350 is provided with an air vent (to ensure that the water in the water tank 350 can be naturally discharged downward from the water outlet pipe 410).

[0042] By providing an atomizing assembly, water mist can be formed and diffused in the heat exchange hollow plate 390 (i.e., in the cavity 360). The evaporation of the water mist absorbs heat, thereby cooling the air flowing through the heat exchange hollow plate 390, further enhancing the heat dissipation capacity of the box-type transformer with interlayer pipe air cooling function. Specifically, the water outlet pipe 410 can naturally drop and discharge the water in the water storage tank 350 into the first annular plate 430. The motor 670 is started to drive the first rotating shaft 440 to rotate, thereby driving the first striking blade 450 to rotate. The rotating first striking blade 450 quickly strikes the water discharged from the water outlet pipe 410, thereby forming a large amount of water mist, achieving an atomization effect.

[0043] The atomizing assembly also includes a second annular plate 470 ; the second annular plate 470 is connected to the upper surface of the partition 420 and surrounds the outside of the first annular plate 430 ; the second annular plate 470 is perpendicular to the partition 420 ; the second annular plate 470 and the first annular plate 430 share a central axis; the first annular plate 430 is provided with a plurality of rectangular through-holes 460 , and the rectangular through-holes 460 are arranged at equal intervals; and the first striking blade 450 is arranged vertically. Small water droplets formed by the striking of the first striking blade 450 are discharged from the rectangular through-holes 460 and splash into the second annular plate 470 , striking the second annular plate 470 to further form a finer water mist, thereby improving the atomization effect.

[0044] Specifically, the atomization assembly also includes a third annular plate 480 and a second striking blade 510; the third annular plate 480 is rotatably connected to the inner wall of the second annular plate 470, and the third annular plate 480 and the second annular plate 470 share a central axis; the third annular plate 480 is perpendicular to the partition 420; the third annular plate 480 is located between the second annular plate 470 and the first annular plate 430; the second striking blade 510 is connected to the inner wall of the third annular plate 480, and the number of the second striking blades 510 is multiple, and each second striking blade 510 is parallel to each other; the second striking blade 510 is tilted relative to the partition 420; the motor 670 is also used to drive the third annular plate 480 to rotate, and the rotation directions of the third annular plate 480 and the first annular plate 430 are opposite.

[0045] The motor 670 drives the third annular plate 480 to rotate, thereby driving the second beating blade 510 to rotate, and the rotation directions of the second beating blade 510 and the first beating blade 450 are opposite, so the small water droplets discharged from the rectangular through hole 460 will be further hit by the second beating blade 510, thereby forming smaller water mist, greatly improving the atomization effect.
