Technical Field

[0001] The invention relates to the technical field of transformer protection, in particular to a high-frequency transformer with a leakage protection structure. Background Art

[0002] A transformer is an electrical device used to change the voltage of alternating current, and it mainly works on the principle of electromagnetic induction. It can convert electrical energy from one voltage level to another, and common uses include step-up and step-down. The core components of the transformer include the primary winding, the secondary winding, and the iron core. At present, the use of transformers is often accompanied by leakage problems. When the environment is humid or the temperature is too high, the insulation strength of the transformer and its lines is reduced, and leakage is prone to occur. Generally, the transformer needs to be placed at a certain height from the ground and kept dry, or equipped with a moisture-proof device, such as the Chinese patent with publication number CN118098796A, which is a transformer with leakage protection function, and uses a cylinder to wrap the transformer for moisture-proof treatment.

[0003] However, in actual use, the method of opening the inner and outer panels is relatively slow, and the ventilation requirements cannot be increased as needed, making the overall dehumidification process inconvenient and the dehumidification efficiency low. Therefore, a high-frequency transformer with a leakage protection structure is designed to solve the above-mentioned problems. Summary of the invention

[0004] The object of the present invention is to provide a high frequency transformer with a leakage protection structure to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a high-frequency transformer with a leakage protection structure, comprising a bottom frame, a transformer body is placed on the upper end of the bottom frame, and a moisture-proof component is installed in the bottom frame;

[0006] The moisture-proof component includes a servo motor, which is fixedly connected to the lower end of the bottom frame, and the output end of the servo motor is fixedly connected to the mounting frame. The outer wall of the mounting frame is fixedly connected to a gear ring, and a plurality of gears are meshed on the gear ring. The lower end of the gear is rotatably connected to the inner wall of the bottom frame, and the middle part of the upper end of the bottom frame is rotatably connected to a moisture-proof baffle. The upper ends of the plurality of moisture-proof baffles pass through the inner wall of the bottom frame to form a protective frame to cover the transformer body.

[0007] In a further embodiment, the moisture-proof baffle is arc-shaped and can be assembled into an annular frame.

[0008] In a further embodiment, the upper end of the moisture-proof baffle is rotatably connected to a protective cover, and a plurality of through openings are opened at the upper end of the protective cover, and the through openings correspond to the transformer body wiring terminals one by one.

[0009] In a further embodiment, the upper end of the through opening is fixedly connected to a fixed frame, a limit assembly is installed in the fixed frame, and the limit assembly includes two rotating rods, which are symmetrically arranged and rotatably connected to the inner wall of the fixed frame.

[0010] In a further embodiment, the middle part of the rotating rod is fixedly connected to a fixing ring, the fixing rings are fixedly connected to a mounting block on one side away from each other, the mounting block is fixedly connected to an elastic sheet on one side, the elastic sheet is fixedly connected to an insertion frame on one side away from the mounting block, and the insertion frame is fixedly connected to a limiting clamp on one side.

[0011] In a further embodiment, a fixing groove is formed at the front of the rotating rod through the side wall of the fixing frame, and a tension spring is fixedly connected in the fixing groove. The front of the tension spring is connected to the rotating handle, and the rotating handle is slidably connected to the fixing groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention is a high-frequency transformer with a leakage protection structure. By controlling the servo motor to drive the gear ring to rotate, the gear ring drives the gear to rotate 90 degrees, so that the moisture-proof baffle is opened or closed after rotation to form an annular frame. When opening or closing, the transformer body inside is exposed and the whole is exposed to the outside, which has the function of dehumidification and ventilation. After being connected to the outside, the excessively high temperature inside will also decrease with the air circulation temperature, which plays a cooling role. After the moisture-proof baffle rotates, it closes to form an annular frame to protect the transformer body, so as to prevent the excessive humidity outside from directly affecting the use of the transformer body.

DETAILED DESCRIPTION

[0028] The following will be described clearly and completely in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1

[0030] See also Figure 1-5 , this embodiment provides a high-frequency transformer with a leakage protection structure, including a bottom frame 1, a transformer body 2 is placed on the upper end of the bottom frame 1, and a moisture-proof component 3 is installed in the bottom frame 1;

[0031] The moisture-proof component 3 includes a servo motor 31, which is fixedly connected to the lower end of the bottom frame 1, and the output end of the servo motor 31 is fixedly connected to the mounting frame 32. The outer wall of the mounting frame 32 is fixedly connected to a gear ring 33, and a plurality of gears 34 are meshed on the gear ring 33. The lower end of the gear 34 is rotatably connected to the inner wall of the bottom frame 1, and the middle part of the upper end of the bottom frame 1 is rotatably connected to a moisture-proof baffle 35. The upper ends of the plurality of moisture-proof baffles 35 pass through the inner wall of the bottom frame 1 to form a protective frame to cover the transformer body 2.

[0032] When the temperature and humidity sensor 9 detects that the internal humidity and temperature are too high, the servo motor 31 can be started, so that the output end of the servo motor 31 drives the mounting frame 32 to rotate, the mounting frame 32 drives the gear ring 33 to rotate, and the gear ring 33 drives a plurality of gears 34 to rotate 90 degrees at the same time. The gear 34 will drive the moisture-proof baffle 35 at the upper end to rotate 90 degrees, so that the moisture-proof baffles 35 are in an open state, such as Figure 2 As shown, at this time, the internal transformer body 2 is exposed and exposed to the outside as a whole, which plays the role of dehumidification and ventilation. After being connected to the outside, the excessively high internal temperature will also decrease with the circulation of air, thereby playing a cooling role.

[0033] The moisture-proof baffle 35 is arc-shaped and can be assembled into a ring frame. Figure 1 As shown, when closed, it blocks rain and heat from the outside.

[0034] When the outside temperature is also high, the servo motor 31 can be started continuously, the output end of the servo motor 31 drives the mounting frame 32 to rotate, the mounting frame 32 drives the gear ring 33 to rotate, the gear ring 33 drives several gears 34 to rotate at the same time, and the gear 34 drives the moisture-proof baffle 35 at the upper end to rotate continuously. At this time, the moisture-proof baffle 35 continues to rotate and fan the air near the transformer body 2, so that the air flow rate near the transformer body 2 is accelerated, thereby cooling the transformer body 2, and the accelerated air flow rate can also make the water vapor disperse faster, thereby accelerating the cooling and dehumidification of the transformer body 2, so that the transformer body 2 can return to normal faster, and avoid leakage of the transformer body 2 caused by slow cooling or dehumidification.

[0035] When it rains or the humidity is too high outside, the servo motor 31 can be used to rotate again, so that the mounting frame 32 drives the gear ring 33 to rotate, and the gear 34 is rotated ninety degrees again, so that the moisture-proof baffle 35 rotates and closes to form an annular frame to protect the transformer body 2, thereby preventing the excessive humidity outside from directly affecting the use of the transformer body 2.

[0036] By controlling the rotation of the servo motor 31, the gear ring 33 drives the gears 34 to rotate. When the gear ring 33 continuously drives the gears 34 to rotate, the moisture-proof baffle 35 on the upper end of the gear 34 continuously rotates to fan the air near the transformer body 2, so that the air flow rate near the transformer body 2 is accelerated, thereby cooling the transformer body 2. The accelerated air flow rate can also disperse the water vapor faster, thereby accelerating the cooling and dehumidification of the transformer body 2, so that the transformer body 2 can return to normal faster.

[0037] The upper end of the moisture-proof baffle 35 is rotatably connected to the protective cover 4. The upper end of the protective cover 4 is provided with a plurality of openings, which correspond one to one with the wiring terminals of the transformer body 2 and are used for the openings reserved for the connection between the wiring terminals and the connectors of the high-voltage wire or the grounding wire.

[0038] The servo motor 31 is controlled to drive the gear ring 33 to rotate, so that the gear ring 33 drives the gear 34 to rotate 90 degrees, so that the moisture-proof baffle 35 is opened or closed after rotation to form an annular frame. When opening or closing, the transformer body 2 inside is exposed and the whole is exposed to the outside, which has the effect of dehumidification and ventilation. After being connected to the outside, the excessively high temperature inside will also be reduced with the air circulation temperature, which has a cooling effect. The moisture-proof baffle 35 is closed after rotation to form an annular frame to protect the transformer body 2, so as to prevent the excessive humidity outside from directly affecting the use of the transformer body 2.

[0039] Embodiment 2

[0040] See also Figure 1-9 , further improvements were made on the basis of Example 1:

[0041] The upper end of the through hole is fixedly connected to the fixed frame 41, and the limiting assembly 5 is installed in the fixed frame 41. The limiting assembly 5 includes two rotating rods 51, which are symmetrically arranged and rotatably connected to the inner wall of the fixed frame 41. The middle part of the rotating rod 51 is fixedly connected to the fixing ring 52, and the fixing ring 52 is fixedly connected to the mounting block 53 on the side away from each other. The mounting block 53 is fixedly connected to an elastic sheet 54 on one side, and the elastic sheet 54 is fixedly connected to an inserting frame 55 on the side away from the mounting block 53. The inserting frame 55 is fixedly connected to a limiting clamping plate 56 on one side. The rotating rod 51 drives the fixing ring 52 to rotate, so that the fixing ring 52 drives the mounting block 53 to rotate, and the mounting block 53 rotates toward the joint between the two, so that the mounting block 53 drives the limiting clamping plate 56 to rotate, so that the limiting clamping plate 56 rotates and clamps the joint, which plays the role of a joint and assists in the connection of the wiring terminals.

[0042] The front of the rotating rod 51 passes through the side wall of the fixed frame 41 to form a fixed groove, and the tension spring 57 is fixedly connected in the fixed groove. The front of the tension spring 57 is connected to the turning handle 6, and the turning handle 6 is slidably connected to the fixed groove. The rear of the turning handle 6 is fixedly connected to the limit rod 61, and the front of the fixed frame 41 is close to the turning handle 6. A plurality of slots 42 are formed, and the limit rods 61 and the slots 42 are adapted.

[0043] Pull the two turning handles 6 at the front of the same fixed frame 41, so that the turning handle 6 drives the limiting rod 61 to move and separate from the slot 42, and pulls the tension spring 57 to extend, so that the turning handle 6 can rotate and drive the rotating rod 51 to rotate, which is convenient for the use of the rotating rod 51.

[0044] After the wiring terminal of the transformer body 2 is connected to the ground wire or the high-voltage wire, the wiring terminal may leak due to the unstable connection, thereby causing the outer shell of the transformer body 2 to leak. Therefore, after the wiring terminal of the transformer body 2 is connected and fixed to the ground wire or the high-voltage wire connector, the two turning handles 6 at the front of the same fixed frame 41 can be pulled on the same side, so that the turning handle 6 drives the limit rod 61 to move and separate from the slot 42, and pull the tension spring 57 to extend. At this time, the turning handle 6 slides in the turning rod 51 and does not separate. Then, the turning handle 6 is rotated to drive the turning rod 51 to rotate 90 degrees, and the turning rod 51 drives the fixing ring 52 to rotate, so that the fixing ring 52 drives the mounting block 53 to rotate, and the mounting block 53 rotates toward the joint between the two, so that the mounting block 53 drives the limit clamp 56 to rotate, so that the limit clamp 56 rotates and clamps the joint, which plays the role of the joint and assists the connection of the wiring terminal. Then, the turning handle 6 is pushed to make the limit rod 61 enter the slot 42 on the other side, so that the turning handle 6 and the turning rod 51 are fixed.

[0045] By setting a limit assembly 5 in the fixed frame 41 for limiting the end of the high-voltage line or the grounding line after connection, the connected end can be clamped and fixed, and the turning handle 6 is plugged into the fixed frame 41 to maintain the clamping effect, act as a joint, and assist in the connection of the wiring terminals.

[0046] The upper end of the protection cover 4 is fixedly connected to the leakage protector 7, the upper end of the protection cover 4 is fixedly connected to the controller 8, a temperature and humidity sensor 9 is installed at the front of the transformer body 2, and the temperature and humidity sensor 9 is electrically connected to the leakage protector 7.

[0047] The temperature and humidity sensor 9 can detect the temperature and humidity near the internal transformer body 2 after the moisture-proof baffle 35 is closed. The control 8 controls the use of the servo motor 31 according to the detection result.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
