This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.
Example one
Referring to fig. 1-3, a dehumidification type pole-mounted transformer suitable for severe cold areas, including casing 1, casing 1 upper end has been seted up smooth stopper chamber 2, the sealed sliding connection of smooth stopper chamber 2 inner wall has magnetism smooth stopper 3, the 3 lateral walls of magnetism smooth stopper pass through reservoir 4 and smooth stopper 2 inner wall elastic connection, casing 1 lower extreme has been seted up bar chamber 5, bar chamber 5 inner wall fixedly connected with baffle 6, baffle 6 equally divide into cooling chamber 51 and heating chamber 52 in the bar chamber 5, the inner wall that smooth stopper chamber 2 kept away from reservoir 4 passes through back flow 7 and reservoir 4 inner wall fixed connection, back flow 7 runs through and sets up in bar chamber 5, heating chamber 52 inner wall symmetry inlays establishes two permanent magnet 8 that the magnetic pole is relative, install on the smooth stopper chamber 2 with the moisture intermittent type pump in casing 1 go into the pump gas mechanism in the cooling chamber 51.
The pump gas mechanism includes that fixed connection is close to the one-way breathing pipe 10 of reservoir 4 inner wall at sliding plug chamber 2, 1 upper end of casing rotates through the pivot and is connected with a plurality of wind cups 9, one of them wind cup 9 adopts magnetic material to make, sliding plug chamber 2 is close to the inner wall of reservoir 4 and passes through one-way outlet duct 11 and cooling chamber 51 inner wall below fixed connection, through-hole 12 has been seted up to 6 lateral walls of baffle top, heating chamber 52 inner wall below passes through blast pipe 13 and casing 1 inner wall fixed connection, cooling chamber 51 bottom has seted up one-way outlet 14.
It should be noted that the one-way air intake pipe 10 allows only air to enter the sliding plug cavity 2 from the housing 1, the one-way air outlet pipe 11 allows only air to enter the cooling cavity 51 from the sliding plug cavity 2, and the one-way water discharge port 14 allows only water to flow out of the cooling cavity 51.
The part of the return pipe 7 located in the heating cavity 52 is arranged spirally, magnetic fluid is arranged in the sliding plug cavity 2, further, when the magnetic fluid flows through the permanent magnet 8, the magnetic heat phenomenon occurs, and the spiral return pipe 7 can increase the heat exchange area and improve the efficiency.
In this embodiment, because the wind force in the severe cold area is large, the wind cup 9 rotates under the impact of the wind force, so that the wind cup 9 made of a magnetic material continuously sweeps over the magnetic sliding plug 3, when the wind cup 9 is close to the magnetic sliding plug 3, the suction force between the wind cup 9 and the magnetic sliding plug 3 is enough to overcome the elastic force of the liquid storage bag 4, and then the magnetic sliding plug 3 slides leftwards, and when the wind cup 9 is far away from the magnetic sliding plug 3, the suction force between the wind cup 9 and the magnetic sliding plug 3 is not enough to overcome the elastic force of the liquid storage bag 4, and then the magnetic sliding plug 3 slides rightwards, and the process is repeated, so that the magnetic sliding plug 3 slides back and forth on the inner wall of the sliding plug cavity 2;
when the magnetic sliding plug 3 slides back and forth, gas in the shell 1 is intermittently pumped into the cooling cavity 51 through the one-way gas suction pipe 10 and the one-way gas outlet pipe 11 in the sliding plug cavity 2, so that the gas enters the cooling cavity 51, then enters the heating cavity 52 through the through hole 12, and then enters the shell 1 again through the gas outlet pipe 13;
meanwhile, when the magnetic sliding plug 3 slides back and forth, the magnetic fluid in the sliding plug cavity 2 circularly flows in the return pipe 7, when the magnetic fluid flows into the heating cavity 52, the magnetic fluid is magnetized under the action of the two permanent magnets 8, according to the magnetocaloric effect, the magnetic moment ordered arrangement of the magnetic material changes when an external magnetic field changes in the heat insulation environment, namely, the magnetic entropy changes, so that the phenomenon of absorption and heat release of the material per se occurs, when the magnetic fluid is changed from disorder to order, the heat release is caused, the magnetic fluid in the return pipe 7 releases the heat per se to heat the heating cavity 52, then, the magnetic fluid after the heat release enters the cooling cavity 51, so that the magnetic fluid is far away from the permanent magnets 8, the magnetization of the permanent magnets 8 is lost, the magnetic fluid is changed from disorder to disorder again, and the magnetic fluid absorbs the heat to the outside in the ordered process, so that the temperature in the cooling cavity 51 is, when making the gas in the casing 1 in the cooling chamber 51, liquid in the gas meets cold liquefaction, and the gas after the liquefaction gets into the temperature rise in the heating chamber 52 afterwards for the corresponding rise of temperature in the casing 1 has improved the transformer on the pole and has still ensured the safe in utilization of transformer on the pole when to the conversion efficiency of voltage.
Example two
Referring to fig. 4-5, a difference from the first embodiment is that a groove 15 is formed in the inner bottom of the sliding plug cavity 2 close to the reservoir 4, a sliding block 16 is connected to the inner wall of the groove 15 in a sliding manner, the lower end of the sliding block 16 is elastically connected to the inner bottom of the groove 15 through a memory spring 17, it should be noted that the memory spring 17 is a nickel-titanium memory alloy, when the temperature on the memory spring reaches a deformation temperature, the memory spring extends in a deformation manner, a clamping groove 18 matched with the sliding block 16 is formed in the lower end of the magnetic sliding plug 3, and a baffle 19 is fixedly connected to the lower.
In this embodiment, when the magnetic sliding plug 3 slides back and forth, the heating cavity 52 will heat the gas entering the interior of the magnetic sliding plug, so that the temperature in the housing 1 gradually rises, when the temperature in the housing 1 rises to reach the deformation temperature of the memory spring 17, the memory spring 17 extends to push the slider 16 to slide upwards, because the upward sliding of the slider 16 is inhibited under the action of the baffle 19, so that the slider 16 keeps the upward sliding tendency, when the magnetic sliding plug 3 slides to the groove 15 on the inner wall of the sliding plug cavity 2, the baffle 19 is separated from the upper end of the groove 15, and the inhibition of the slider 16 by the baffle 19 disappears, so that the slider 16 slides upwards and is inserted into the slot 18, and the position of the magnetic sliding plug 3 is fixed, so that the magnetic fluid does not flow, and is not pumping air in the cooling cavity 51, and further, so that the interior of the housing 1 is not heated, and the temperature in the housing 1 is prevented from rising continuously, affecting the life of the electronic components inside the housing 1.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
