Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and more particularly to a cycloid thermal protection transformer. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core (magnetic core). Transformer cooling refers to the use of certain methods to dissipate the heat generated by the operating transformer. When the transformer is running, the heat generated by the loss in the windings and the iron core must be dissipated in time to avoid overheating and insulation damage. For small-capacity transformers, the ratio of the surface area to the transformer volume is relatively large, and self-cooling can be used to dissipate the heat through radiation and natural convection.

[0003] When the transformer is running, a large amount of heat will be generated. In the prior art, heat dissipation fins are usually arranged on the surface of the transformer to increase the heat dissipation area and achieve the heat dissipation effect. In actual use, there is an abnormal situation of excessive temperature. When the temperature abnormality occurs, if it is not discovered in time and the corresponding measures are not taken in time, it is easy to affect the safe and stable operation of the transformer, and even there are certain safety hazards. In particular, when the local area is overheated, it is difficult to effectively cool down the local area in time. Summary of the invention

[0004] 1. Technical problems to be solved

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a cycloid thermal protection transformer. By arranging luminous strips between the heat dissipation fins, when local overheating occurs, the connecting ring on the thermal swing ball melts, and the pre-fall hemisphere is separated from the positioning hemisphere under the action of gravity, and drives the luminous strip to swing. At the same time, it can swing repeatedly many times under the elastic force of the rebound ring, thereby accelerating the local air flow efficiency, and the pre-crack capsule will also rupture under the traction of the water storage capsule, thereby contacting with the water in the water storage capsule to form a cooling condition, thereby temporarily cooling the local area. After the luminous strip falls, the fluorescent liquid in the warning top capsule will also remain, forming a more obvious vertical luminous strip, thereby providing intuitive warning to technical personnel, greatly improving the safety of the transformer body during operation.

[0006] 2. Technical solution

[0007] To solve the above problems, the present invention adopts the following technical solutions.

[0008] A cycloid thermal protection transformer comprises a transformer body, wherein a plurality of evenly distributed heat dissipation fins are installed at the outer end of the transformer body, a plurality of staggeredly distributed warning top capsules and magnetic suction sheets are fixedly connected to one side wall of the heat dissipation fins, a plurality of evenly distributed heat conductive patches are fixedly connected to the other side wall of the heat dissipation fins, a heat swing ball is inlaid and connected to the heat conductive patch, a luminous strip is connected between the warning top capsules and the heat swing balls on an adjacent pair of the heat dissipation fins, and the heat swing balls include a positioning hemisphere, a pre-fall hemisphere and a connection The positioning hemisphere and the pre-falling hemisphere are symmetrically connected on both sides of the connecting ring, and the positioning hemisphere is inlaid and connected to the thermal conductive patch, the pre-falling hemisphere is inlaid and connected with a rebound ring and a water storage bag at one end away from the positioning hemisphere, and the rebound ring is surrounded by the outside of the water storage bag, a pre-splitting bag is arranged on the inner side of the positioning hemisphere, a baffle is fixedly connected at the opening of the positioning hemisphere, a blocking hole is opened on the baffle, and the water storage bag passes through the blocking hole and is connected to the pre-splitting bag, and a plurality of evenly distributed flexible thermal conductive strips are fixedly connected between the pre-splitting bag and the positioning hemisphere.

[0009] Furthermore, the rebound-assisting ring includes an outer elastic layer and an inner magnetic layer attached to the back of the outer elastic layer. The outer elastic layer is made of elastic material. Relying on the rebound effect of the outer elastic layer, the pre-fall hemisphere can swing multiple times when falling, thereby improving the air flow effect nearby. The inner magnetic layer can ensure that the outer elastic layer rebounds in a preset posture under the magnetic attraction of the magnetic attraction sheet, and is not prone to tilting or displacement.

[0010] Furthermore, the water storage bag includes an outer expansion membrane, an inner fixed sleeve and a stretching tube which are connected in sequence, a closed space is formed between the outer expansion membrane and the inner fixed sleeve, and water is stored in the closed space, the outer expansion membrane is located on the outer surface of the pre-fall hemisphere, the stretching tube is connected between the inner fixed sleeve and the pre-splitting bag, and the stretching tube is communicated with the inner fixed sleeve, when the pre-fall hemisphere falls, the stretching tube will pull the pre-splitting bag and the baffle to collide, thereby triggering the rupture of the pre-splitting bag, and then the stretching tube is stretched until the outer expansion membrane contacts and squeezes the heat dissipation fins, so that the water inside can be squeezed into the space of the pre-splitting bag, and then the cooling effect is mainly concentrated in the pre-splitting bag, and the overheating area is fully cooled and protected.

[0011] Furthermore, the outer expansion membrane and the stretching tube are both made of elastic materials, and the inner sleeve is made of hard material.

[0012] Furthermore, the positioning hemisphere and the pre-falling hemisphere are both made of hard heat-conductive material, and the connecting ring is made of hot-melt material.

[0013] Furthermore, the pre-crack capsule includes an outer shell, an inner pre-crack shell and a plurality of cooling particles, a sphere is formed between the outer shell and the inner pre-crack shell, the stretch tube is connected to the opening of the outer shell, and the inner pre-crack shell is located on the inner side of the stretch tube, the cooling particles are filled between the outer shell and the inner pre-crack shell, and the inner pre-crack shell will rupture after being impacted, thereby exposing the cooling particles inside, and when the water storage bag is squeezed, water will be squeezed into the outer shell to contact the cooling particles, triggering the cooling protection effect.

[0014] Furthermore, the outer shell is made of a hard heat-conducting material, the inner pre-crack shell is made of a brittle material, the cooling particles are made of saltpeter and have a particle size larger than the blocking hole. The cooling particles absorb a large amount of heat to form a cooling effect when dissolved in water, while the cooling particles cannot pass through the blocking hole and can only gradually dissolve in the inner pre-crack shell to absorb heat, thereby mainly concentrating the cooling effect on the overheated area.

[0015] Furthermore, the warning top bag includes a shielding inner layer, an outer liquid storage cover and a self-swinging ball. The shielding inner layer is fixedly connected to the heat dissipation fins, and the outer liquid storage cover is sleeved on the outside of the shielding inner layer. A movable hole matching the self-swinging ball is provided between the shielding inner layer and the lower end of the outer liquid storage cover. An overflow hole connected to the luminous strip is provided on the self-swinging ball. Fluorescent liquid is filled between the shielding inner layer and the outer liquid storage cover. It is difficult for the fluorescent liquid to enter the luminous strip in an inclined state. When the luminous strip follows the pre-fall hemisphere to fall, the fluorescent liquid can enter the luminous strip through the overflow hole to form a vertical luminous strip for early warning, and the fluorescent liquid can be squeezed back by squeezing the luminous strip during later maintenance.

[0016] Furthermore, the light-emitting strip is a hollow transparent structure, and when the light-emitting strip is in a tilted state, the overflow hole on the self-oscillating ball and the shielding inner layer remain closed.

[0017] Furthermore, the height difference between the warning top bag and the magnetic suction sheet is consistent with the length of the light-emitting strip, and the width of the light-emitting strip is not less than the width of the heat dissipation fins.

[0018] 3. Beneficial effects

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] (1) This solution can be achieved by setting luminous strips between the heat dissipation fins. When local overheating occurs, the connecting ring on the thermal swing ball melts, and the pre-fall hemisphere separates from the positioning hemisphere under the action of gravity, driving the luminous strip to swing. At the same time, it can swing repeatedly under the elastic force of the rebound ring, thereby accelerating the local air flow efficiency. Under the traction of the water storage bag, the pre-crack capsule will also rupture, thereby contacting with the water in the water storage bag to form a cooling condition, thereby providing temporary cooling protection for the local area. After the luminous strip falls, the fluorescent liquid in the warning top bag will also remain, forming a more obvious vertical luminous strip, thereby providing an intuitive warning to the technicians, greatly improving the safety of the transformer body during operation.

[0021] (2) The rebound-assisting ring includes an outer elastic layer and an inner magnetic layer attached to the back of the outer elastic layer. The outer elastic layer is made of elastic material. Relying on the rebound effect of the outer elastic layer, the pre-fall hemisphere can swing multiple times when falling, thereby improving the air flow effect nearby. The inner magnetic layer can ensure that the outer elastic layer rebounds in a preset posture under the magnetic attraction of the magnetic attraction sheet, and is not prone to tilting or displacement.

[0022] (3) The water storage bag includes an outer expansion membrane, an inner fixed sleeve and a stretching tube which are connected in sequence. A closed space is formed between the outer expansion membrane and the inner fixed sleeve, and water is stored in the closed space. The outer expansion membrane is located on the outer surface of the pre-fall hemisphere. The stretching tube is connected between the inner fixed sleeve and the pre-splitting bag, and the stretching tube is communicated with the inner fixed sleeve. When the pre-fall hemisphere falls, the stretching tube will pull the pre-splitting bag and the baffle to collide, thereby triggering the rupture of the pre-splitting bag. Then, the stretching tube stretches until the outer expansion membrane contacts and squeezes the heat dissipation fins, so that the water inside can be squeezed into the space of the pre-splitting bag, thereby concentrating the cooling effect mainly in the pre-splitting bag, and fully cooling the overheated area.

[0023] (4) The pre-crack capsule includes an outer shell, an inner pre-crack shell and a plurality of cooling particles. A sphere is formed between the outer shell and the inner pre-crack shell. The stretch tube is connected to the opening of the outer shell, and the inner pre-crack shell is located inside the stretch tube. The cooling particles are filled between the outer shell and the inner pre-crack shell. When the inner pre-crack shell is impacted, it will rupture, thereby exposing the cooling particles inside. When the water storage bag is squeezed, water will be squeezed into the outer shell to contact the cooling particles, triggering the cooling protection effect.

[0024] (5) The outer shell is made of hard heat-conducting material, the inner pre-crack shell is made of brittle material, and the cooling particles are made of saltpeter and have a particle size larger than the blocking hole. When the cooling particles are dissolved in water, they will absorb a large amount of heat to form a cooling effect, while the cooling particles cannot pass through the blocking hole and can only gradually dissolve in the inner pre-crack shell to absorb heat, thereby concentrating the cooling effect mainly on the overheated area.

[0025] (6) The warning top bag includes a shielding inner layer, an outer liquid storage cover and a self-swinging ball. The shielding inner layer is fixedly connected to the heat dissipation fins, and the outer liquid storage cover is sleeved on the outer side of the shielding inner layer. A movable hole matching the self-swinging ball is provided between the shielding inner layer and the lower end of the outer liquid storage cover. The self-swinging ball is provided with an overflow hole connected to the luminous strip. Fluorescent liquid is filled between the shielding inner layer and the outer liquid storage cover. It is difficult for the fluorescent liquid to enter the luminous strip in an inclined state. When the luminous strip follows the pre-fall hemisphere to fall, the fluorescent liquid can enter the luminous strip through the overflow hole to form a vertical luminous strip for early warning. In the later maintenance, the fluorescent liquid can be squeezed back by squeezing the luminous strip. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] See also Figure 7 The rebound-assisting ring 8 includes an outer elastic layer 81 and an inner magnetic layer 82 attached to the back of the outer elastic layer 81. The outer elastic layer 81 is made of elastic material. Relying on the rebound effect of the outer elastic layer 81, the pre-fall hemisphere 62 can swing multiple times when falling, thereby improving the air flow effect nearby. The inner magnetic layer 82 can ensure that the outer elastic layer 81 rebounds in a preset posture under the magnetic attraction of the magnetic attraction sheet 7, and is not prone to tilting or deflection.

[0043] The water storage bag 9 includes an outer expansion membrane 91, an inner fixed sleeve 92 and a stretching tube 93 which are connected in sequence. A closed space is formed between the outer expansion membrane 91 and the inner fixed sleeve 92, and water is stored in the closed space. The outer expansion membrane 91 is located on the outer surface of the pre-fall hemisphere 62, and the stretching tube 93 is connected between the inner fixed sleeve 92 and the pre-splitting bag 10, and the stretching tube 93 is communicated with the inner fixed sleeve 92. When the pre-fall hemisphere 62 falls, the stretching tube 93 will pull the pre-splitting bag 10 to collide with the baffle, thereby triggering the rupture of the pre-splitting bag 10, and then the stretching tube 93 is stretched until the outer expansion membrane 91 contacts and squeezes the heat dissipation fins 2, so that the water inside can be squeezed into the space of the pre-splitting bag 10, thereby mainly concentrating the cooling effect in the pre-splitting bag 10, and fully cooling the overheated area.

[0044] The outer expansion membrane 91 and the stretching tube 93 are both made of elastic materials, and the inner fixed sleeve 92 is made of hard material.

[0045] The positioning hemisphere 61 and the pre-falling hemisphere 62 are both made of hard heat-conductive material, and the connecting ring 63 is made of hot-melt material.

[0046] See also Figure 8 The pre-splitting capsule 10 includes an outer shell 101, an inner pre-splitting shell 102 and a plurality of cooling particles 103. A sphere is formed between the outer shell 101 and the inner pre-splitting shell 102. The stretching tube 93 is connected to the opening of the outer shell 101, and the inner pre-splitting shell 102 is located inside the stretching tube 93. The cooling particles 103 are filled between the outer shell 101 and the inner pre-splitting shell 102. When the inner pre-splitting shell 102 is impacted, it will rupture, thereby exposing the cooling particles 103 inside. When the water storage bag 9 is squeezed, water will be squeezed into the outer shell 101 to contact the cooling particles 103, triggering the cooling protection effect.

[0047] The outer shell 101 is made of a hard heat-conducting material, the inner pre-crack shell 102 is made of a brittle material, the cooling particles 103 are made of saltpeter and have a particle size larger than the blocking hole. The cooling particles 103 absorb a large amount of heat to form a cooling when dissolved in water, while the cooling particles 103 cannot pass through the blocking hole and can only gradually dissolve in the inner pre-crack shell 102 to absorb heat, thereby concentrating the cooling effect mainly on the overheating area.

[0048] See also Fig. 9 The warning top bag 4 includes a shielding inner layer 41, an outer liquid storage cover 42 and a self-swinging ball 43. The shielding inner layer 41 is fixedly connected to the heat dissipation fin 2, and the outer liquid storage cover 42 is sleeved on the outer side of the shielding inner layer 41. A movable hole matching the self-swinging ball 43 is provided between the lower ends of the shielding inner layer 41 and the outer liquid storage cover 42. An overflow hole connected to the luminous strip 3 is provided on the self-swinging ball 43. Fluorescent liquid is filled between the shielding inner layer 41 and the outer liquid storage cover 42. It is difficult for the fluorescent liquid to enter the luminous strip 3 in an inclined state. When the luminous strip 3 follows the pre-fall hemisphere 62 to fall, the fluorescent liquid can enter the luminous strip 3 through the overflow hole to form a vertical luminous strip for early warning, and the fluorescent liquid can be squeezed back by squeezing the luminous strip 3 during later maintenance.

[0049] The light-emitting strip 3 is a hollow transparent structure, and when the light-emitting strip 3 is in a tilted state, the overflow hole on the self-oscillating ball 43 and the shielding inner layer 41 remain closed.

[0050] The height difference between the warning top bag 4 and the magnetic attraction sheet 7 is consistent with the length of the light-emitting strip 3 , and the width of the light-emitting strip 3 is not less than the width of the heat dissipation fin 2 .

[0051] The present invention can arrange the luminous strip 3 between the heat dissipation fins 2. When overheating occurs locally, the connecting ring 63 on the heat swing ball 6 melts, and the pre-fall hemisphere 62 is separated from the positioning hemisphere 61 under the action of gravity, and drives the luminous strip 3 to swing. At the same time, it can swing repeatedly for many times under the elastic force of the rebound ring 8, thereby accelerating the local air flow efficiency, and the pre-crack capsule 10 will also rupture under the traction of the water storage capsule 9, thereby contacting with the water in the water storage capsule 9 to form a cooling condition, thereby temporarily cooling the local area. After the luminous strip 3 falls, the fluorescent liquid in the warning top capsule 4 will also remain, forming a more obvious vertical luminous band, thereby providing intuitive warning to technical personnel, greatly improving the safety of the transformer body 1 during operation.

[0052] The above are only preferred specific implementations of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
