[0016] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0017] The present invention provides a high-power high-frequency switching power supply water-cooled transformer, such as Figures 1 to 7 As shown, it includes: a transformer 1, which is a high-power high-frequency switching power supply water-cooled transformer in the prior art, a copper busbar 2 is provided on the transformer 1, and a connecting hole 3 is provided on the copper busbar 2, which can facilitate the connection of the copper busbar 2 with the copper busbar on the external equipment, and a moisture-proof component is provided on the outside of the copper busbar 2, which can protect the copper busbar 2 from moisture; The moisture-proof assembly includes: a circular frame 4, a circular ring 5, a telescopic cover 6, an air outlet 7, an air duct 8, a dehumidification assembly for dehumidifying the air flow blown out from the air duct 8, and a support assembly for supporting the circular ring 5; The round frame 4 is fixedly installed on the outside of the transformer 1. The round frame 4 is located outside the copper busbar 2. The air outlet 7 is set at the top of the round frame 4. The circular ring 5 is connected to the round frame 4 through the telescopic cover 6. The air duct 8 is set on the outside of the transformer 1. The air duct 8 corresponds to the position of the air outlet 7. The bottom of the air duct 8 is equidistantly provided with circular holes.

[0018] When in use, the air duct 8 is connected to the external blower, the copper bar 2 is connected to the external equipment, and then the ring 5 is pulled to move it in the direction away from the circular frame 4, thereby expanding the telescopic cover 6. Finally, the telescopic cover 6 cooperates with the circular ring 5 to cover the connection between the copper bar 2 and the external equipment. The supporting assembly supports the circular ring 5 so that it is in a static state, and air is blown into the air duct 8 through the blower. The air is blown out through the circular hole, dehumidified by the dehumidification assembly, and then enters the space formed by the circular frame 4, the telescopic cover 6, and the circular ring 5 through the blowing port 7, and then blown out, so that the humid air from the outside cannot contact the copper bar 2, thereby preventing the connection between the copper bar 2 and the external equipment from moisture, so as to ensure the normal use of the copper bar 2, and then ensure the normal use of the transformer as a whole, and the airflow generated in the space formed by the circular frame 4, the telescopic cover 6, and the circular ring 5 can take away the heat generated by the copper bar 2 to dissipate heat.

[0019] like Figures 2 to 7 As shown, the dehumidification assembly includes: a moisture absorbing strip 11, a heat dissipation port 12 opened on the outside of the transformer 1, a guide wheel 13, a driving assembly for driving the guide wheel 13 to rotate, and an adjustment assembly capable of adjusting the vertical position of the air duct 8; The guide wheel 13 is rotatably installed on the outside of the transformer 1, and the moisture absorbing strip 11 is sleeved on the outside of the guide wheel 13 and the circular frame 4. The moisture absorbing strip 11 can pass through the heat dissipation port 12. The moisture absorbing strip 11 passes between the air duct 8 and the circular frame 4, and the air duct 8 conflicts with the moisture absorbing strip 11.

[0020] After the airflow out of the air duct 8 passes through the moisture absorbing strip 11, moisture can be removed, thereby achieving dehumidification of the airflow. After a period of time, the air duct 8 is adjusted upward by the adjustment component so that the air duct 8 leaves the moisture absorbing strip 11, and then the guide wheel 13 is driven by the driving component to rotate, thereby driving the moisture absorbing strip 11 to move, and the moisture-absorbing part is rotated to the position away from the air duct 8, and the heat inside the transformer 1 can be dissipated outward through the heat dissipation port 12, and the moisture absorbing strip 11 at the heat dissipation port 12 can be dried. With the movement of the moisture absorbing strip 11, the dry moisture absorbing strip 11 can be moved to the air duct 8. Then, the driving component stops driving the guide wheel 13, and the air duct 8 is reset by the adjustment component so that the matching circular frame 4 clamps the moisture absorbing strip 11, completing the switching of the dry part of the moisture absorbing strip 11. The above operation is repeated at each interval, and finally it can be ensured that the dry moisture absorbing strip 11 can always be located at the air duct 8 to dehumidify the airflow blown out thereof, and the specific interval time is determined according to the humidity on site.

[0021] like Figure 3 and Figure 7 As shown, the driving assembly includes: a motor 14, a bracket, a baffle 15, a baffle 16, and a rectangular groove opened on the outside of the guide wheel 13; The motor 14 is fixedly mounted on the outside of the transformer 1 through a bracket, the baffle 15 is fixedly sleeved on the output shaft of the motor 14, the end of the output shaft of the motor 14 matches the rectangular groove and extends into the rectangular groove, the baffle 16 is arranged on the outside of the air duct 8, and the baffle 15 and the baffle 16 are both in contact with the outside of the moisture-absorbing strip 11.

[0022] The baffle 15 and the baffle 16 can limit the hygroscopic strip 11 so that it cannot separate from the round frame 4. The motor 14 is started so that its output shaft cooperates with the rectangular groove to rotate the guide wheel 13. The guide wheel 13 rotates the hygroscopic strip 11 by relying on the friction between the guide wheel 13 and the hygroscopic strip 11, thereby driving the hygroscopic strip 11.

[0023] like Figures 2 to 7 As shown, an arc-shaped groove is provided on the outside of the transformer 1, and an arc-shaped tube 17 is provided in the arc-shaped groove. The top of the air duct 8 is connected to a connecting tube 9, and one side of the connecting tube 9 is connected to a joint tube 10. The top of the connecting tube 9 is connected to the arc-shaped tube 17 through a hose 18. Specifically, one end of the hose 18 passes through the transformer 1 and is connected to the arc-shaped tube 17. A solenoid valve 19 is provided inside the connecting tube 9, and the solenoid valve 19 is located below the joint tube 10. An opening is provided on the outside of the arc-shaped tube 17, and the position of the opening is opposite to the side of the moisture-absorbing strip 11. When the air duct 8 is at the bottom, the air duct 8 can close the opening on the arc-shaped tube 17. A filter is provided at the air inlet end of the external blower, and the air can be filtered through the filter to prevent dust and impurities from entering the air duct 8.

[0024] When the air duct 8 contacts the moisture absorbing strip 11, the solenoid valve 19 opens, connecting the joint pipe 10 to the external blower. The airflow blown by the blower enters the connecting pipe 9 through the joint pipe 10. Since the opening of the arc tube 17 is now blocked by the air duct 8, the airflow can only enter the air duct 8 and then blow out through the circular hole. If the environment is humid and accompanied by a small amount of dust, the dust will fall on the dried moisture absorbing strip 11. This part of the dust will hinder the airflow through the moisture absorbing strip 11, affecting the moisture-proof process. Therefore, when the air duct 8 rises, the air duct 8 cancels the closure of the opening. At this time, the solenoid valve 19 is closed, and the air flow enters the arc tube 17 through the hose 18 and blows outward through the opening, so that the dry moisture-absorbing strip 11 that is subsequently moved to the bottom of the air duct 8 can be blown, thereby blowing away the dust and impurities on the surface of the moisture-absorbing strip 11, thereby cleaning the moisture-absorbing strip 11. Then the air duct 8 is reset, and the solenoid valve 19 is opened. The subsequent air flow blown out from the air duct 8 will not be hindered by dust and impurities, thereby ensuring the moisture-proof effect.

[0025] like Figure 4 As shown, the adjustment assembly includes: a slider 20, an electromagnet 21, and a spring 22; A slide groove is provided on the outside of the transformer 1, and a slider 20 is slidably installed in the slide groove. The slider 20 is fixedly connected to the air duct 8. The material of the slider 20 is a material that can be magnetically adsorbed, and the material of the slider 20 is iron. The spring 22 fixes the top of the slider 20 to the top wall of the slide groove, and the electromagnet 21 is fixedly installed on the top wall of the slide groove.

[0026] The electromagnet 21 is energized to make it magnetic, and the electromagnet 21 attracts the slider 20 and makes it rise with the air duct 8, so that the baffle 16 moves accordingly. As the slider 20 rises, the compression spring 22 causes it to deform, and eventually the air duct 8 leaves the moisture-absorbing strip 11 and cancels the closure of the opening. The baffle 16 will not block the opening. The electromagnet 21 is de-energized, and the compressed spring 22 is reset, thereby restoring the slider 20 and the air duct 8, so that the air duct 8 conflicts with the moisture-absorbing strip 11.

[0027] like Figure 3 As shown, the support assembly includes: a sleeve 23, a sliding rod slidably arranged inside the sleeve 23, and a fixing plate 24; The bushing 23 is symmetrically fixedly installed on the outside of the transformer 1. The bushing 23 is located on both sides of the circular frame 4. The fixing plate 24 is slidably installed on one end of the slide rod. A groove corresponding to the fixing plate 24 is opened on the outside of the circular ring 5. The fixing plate 24 extends into the groove. The fixing plate 24 and the circular ring 5 are connected by bolts.

[0028] When the desiccant strip 11 needs to be replaced, the bolts are removed, and the fixing plate 24 is pulled to slide away from the groove. Then the air duct 8 is lifted so that the baffle 16 removes the restriction on the desiccant strip 11, and the bracket is disassembled so that the output shaft of the motor 14 leaves the guide wheel 13. At this time, the desiccant strip 11 can be removed for replacement.

[0029] like Figure 3 As shown, the moisture absorbing strip 11 is a mesh cloth bonded with moisture absorbing silica gel particles, the round frame 4 is made of stainless steel, the outer side of the round frame 4 is smooth, and when the guide wheel 13 rotates, it can cooperate with the friction force to drive the moisture absorbing strip 11 to move.

[0030] Working principle: When in use, connect the joint pipe 10 to the output end of the external blower, connect the copper bus 2 to the external equipment, then pull the ring 5 to move it away from the round frame 4, so as to unfold the telescopic cover 6, and finally the telescopic cover 6 cooperates with the ring 5 to cover the connection between the copper bus 2 and the external equipment. The support component supports the ring 5 to keep it in a static state, and blows air into the air duct 8 through the blower. The air flow blown by the blower enters the connecting pipe 9 through the joint pipe 10. Since the opening of the arc tube 17 is closed by the air duct 8 at this time, This airflow can only enter the air duct 8, then blow out through the circular hole, and after being dehumidified by the moisture-absorbing strip 11, enter the space formed by the circular frame 4, the telescopic cover 6, and the circular ring 5 through the air outlet 7, and then blow out, so that the external humid air cannot come into contact with the copper busbar 2, thereby preventing moisture from entering the connection between the copper busbar 2 and the external equipment, ensuring the normal use of the copper busbar 2, and then ensuring the normal use of the transformer as a whole. In addition, the airflow generated in the space formed by the circular frame 4, the telescopic cover 6, and the circular ring 5 can take away the heat generated by the copper busbar 2 and dissipate it. After the airflow from the air duct 8 passes through the moisture absorbing strips 11, moisture is removed from the moisture absorbing strips 11, thereby achieving dehumidification of the airflow. After a period of time, the air duct 8 is adjusted upward by the adjustment component, so that the air duct 8 leaves the moisture absorbing strips 11, and then the guide wheel 13 is driven by the driving component to rotate, thereby driving the moisture absorbing strips 11 to move, and the moisture-absorbing part is rotated to leave the air duct 8, and the heat inside the transformer 1 can be dissipated outward through the heat dissipation port 12, and the moisture absorbing strips 11 at the heat dissipation port 12 can be dried. With the movement of the moisture absorbing strips 11, the dry moisture absorbing strips 11 can be moved to the air duct 8. Then, the driving component stops driving the guide wheel 13, and the air duct 8 is reset by the adjustment component, so that the matching circular frame 4 clamps the moisture absorbing strips 11, completing the switching of the dry part of the moisture absorbing strips 11. The above operation is repeated at intervals thereafter, and finally it is ensured that the dry moisture absorbing strips 11 can always be located at the air duct 8 to dehumidify the airflow blown out thereof. The specific interval time is determined according to the humidity on site. When the air duct 8 contacts the moisture absorbing strip 11, the solenoid valve 19 opens, connecting the joint pipe 10 to the external blower. The airflow blown by the blower enters the connecting pipe 9 through the joint pipe 10. Since the opening of the arc tube 17 is now blocked by the air duct 8, the airflow can only enter the air duct 8 and then blow out through the circular hole. If the environment is humid and accompanied by a small amount of dust, the dust will fall on the dried moisture absorbing strip 11. This part of the dust will hinder the airflow through the moisture absorbing strip 11, affecting the moisture-proof process. Therefore, when the air duct 8 rises, the air duct 8 cancels the closure of the opening. At this time, the solenoid valve 19 is closed, and the air flow enters the arc tube 17 through the hose 18 and blows outward through the opening, so that the dry moisture-absorbing strip 11 that is subsequently moved to the bottom of the air duct 8 can be blown, thereby blowing away the dust and impurities on the surface of the moisture-absorbing strip 11, thereby cleaning the moisture-absorbing strip 11. Then the air duct 8 is reset, and the solenoid valve 19 is opened. The subsequent air flow blown out from the air duct 8 will not be hindered by dust and impurities, thereby ensuring the moisture-proof effect.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
