Description

Technical Field

[0001] The invention relates to the technical field of transformer heat dissipation, and in particular to an air-cooling heat dissipation device for a transformer. Background Art

[0002] The components of the transformer include the transformer body (iron core, winding, insulation, lead wire), transformer oil, oil tank and cooling device, voltage regulating device, protective device (dehumidifier, safety airway, gas relay, oil storage cabinet and temperature measuring device, etc.) and outlet bushing;

[0003] The no-load loss and load loss generated by the transformer during operation are converted into heat energy, so the transformer will heat up. The heat generated by the transformer is dissipated to the surrounding cooling medium through conduction, convection and radiation. The transformer will heat up and dissipate heat at the same time. When the heat generated by the transformer is greater than the heat dissipation, the temperature of each part of the transformer will rise. When the heat generation and heat dissipation of the transformer reach a balance, the temperature of the transformer will maintain a certain value and will no longer continue to rise. The temperature at this time is relatively stable. This relatively stable temperature is also the temperature of each part of the transformer under normal circumstances. The greater the heat generated by the transformer, the greater the loss, the smaller the heat dissipation, and the higher the temperature. At this time, there needs to be a corresponding sufficient cooling device to reduce the temperature of the transformer to an allowable range;

[0004] Traditional cooling uses oil cooling, but exposure to the sun in summer will cause the temperature of the transformer fins to be too high. The fins act as the heat dissipation conduction of the refrigerant, so the high temperature of the fins themselves cannot be effectively released, so the heat dissipation of the refrigerant cannot be achieved. As a heat exchange medium, if the temperature of the refrigerant itself is too high, the heat dissipation of the transformer cannot be achieved, and there will be safety hazards.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0038] Example 1

[0039] Reference Figure 1-2 , an air-cooling heat dissipation device for a transformer, comprising:

[0040] The main frame part 100 includes a cross arm 101, which is installed between two poles and used to install the transformer. The bottom of the cross arm 101 is symmetrically provided with diagonal braces 102, and the ends of the diagonal braces 102 are provided with clamps 103 fixed to the poles.

[0041] The air cooling part 200 is arranged on both sides of the cross arm 101 for air cooling and heat dissipation of the transformer.

[0042] Furthermore, the air cooling part 200 includes a fan 1 201 and a fan 202 . The fan 1 201 and the fan 2 202 are respectively installed on both sides of the transformer, and the wind directions of the fan 1 201 and the fan 2 202 are controlled by a control component 203 .

[0043] Specifically, the fan 1 201 and the fan 2 202 use centrifugal fans, which can change the wind direction by controlling the motor (the driving source of the fan 1 201 and the fan 2 202) to rotate forward / reverse, thereby achieving the function of adjusting the air outlet direction;

[0044] The control component includes a microcomputer controller and a monitoring component. The monitoring component includes a temperature sensor and a wind vane. The temperature sensor is installed on the refrigerant loop to monitor the temperature of the refrigerant in the loop. The wind vane is used to monitor the wind direction. All the monitored data are transmitted to the microcomputer controller. The microcomputer controller transmits the data to the background terminal through the transmission module. The terminal controls the opening and closing of the fan 1 201 and the fan 2 202 and the wind direction conversion according to the returned data.

[0045] The fan 1 201 and the fan 2 202 are arranged opposite to each other. If the fan 1 201 is in the west, then the fan 202 is in the east. When there is no wind, the fan 1 201 and the fan 2 202 can be controlled to blow and draw respectively. The air outlet of the fan 1 201 is directly blown to the heat dissipation hole area on the surface of the transformer, and the fan 2 202 blows outwards. Therefore, suction will be generated on the side close to the transformer. The suction will quickly draw out the wind blown by the fan 1 201 to the heat dissipation hole of the transformer, thereby accelerating the air flow movement and improving the heat dissipation effect. If the wind is west, the wind direction will blow from east to west. At this time, the fan 1 201 and the fan 2 202 can be controlled to blow and draw respectively. 01 and fan 2 202 all blow toward the west, thereby sucking in the airflow from the east and accelerating it to the west. At this time, by changing the wind direction of fan 1 201 and fan 2 202, the impact with the natural airflow from east to west can be avoided. If the wind is east wind or south wind, fan 1 201 is controlled to blow toward the west and fan 2 202 is controlled to blow toward the east, thereby forming a negative pressure in the heat dissipation holes inside the transformer. The negative pressure can draw airflow from the east and south. The airflow passes through the heat dissipation holes and is then drawn out by fan 1 201 and fan 2 202 respectively, thereby maximizing the heat dissipation efficiency.

[0046] The structure is used to increase the fluidity of the airflow, improve the heat dissipation efficiency, guide and increase the airflow, and prevent backblowing, thereby avoiding damage to the heat dissipation airflow around the transformer.

[0047] Example 2

[0048] Reference Figure 3-6 This embodiment is different from the first embodiment in that the air-cooling heat dissipation device for transformers in this embodiment further includes:

[0049] The mounting seat portion 300 is used to mount the air cooling portion 200 on the outside of the cross arm 101;

[0050] The mounting seat part 300 includes a mounting plate 301 and a bottom supporting connection block 302 for carrying the mounting plate 301. The bottom supporting connection block 302 is fixed on the cross arm 101, and a clamping fixing block 303 is arranged above the bottom supporting connection block 302. The clamping fixing block 303 and the bottom supporting connection block 302 are quickly disassembled and assembled through a plug-in assembly 304.

[0051] Furthermore, the plug-in assembly 304 includes a lock core component 304a disposed inside the bottom supporting connection block 302 and a claw component 304b disposed on one side of the lock core component 304a. The claw component 304b is driven by the driving component 304c to realize the engagement or disengagement of the claw component 304b with the lock core component 304a.

[0052] Furthermore, the lock core component 304a includes a guide rod 304a-1 fixed to one end inside the bottom supporting connecting block 302, a chuck 304a-2 is fixed to the end of the guide rod 304a-1, and an external movable sleeve of the guide rod 304a-1 is provided with a movable disk 304a-3, and an external fixed sleeve of the guide rod 304a-1 is provided with a limiting disk 304a-4 for limiting the movable travel of the movable disk 304a-3.

[0053] Furthermore, the claw member 304b includes a disc 304b-1, an L-arm 304b-2 is equidistantly fixed on one side of the disc 304b-1, a slot 304b-3 is provided at one end of the L-arm 304b-2, an inner end of the slot 304b-3 is rotatably connected to a support arm 304b-4, and a pneumatic rod 304b-5 is rotatably connected between the inner side of the support arm 304b-4 and the slot 304b-3.

[0054] Specifically, a slot is provided on the outer side of the bottom support connection block 302, a touch rod is slidably connected in the slot, and the other end of the touch rod is fixedly connected to the movable disk 304a-3, and the movable disk 304a-3 can be driven to slide on the guide rod 304a-1 by toggling the touch rod;

[0055] The chuck 304a-2 is a conical structure. When the chuck 304b-1 is clamped, the disk 304b-1 will drive the L arm 304b-2 to move when it is pushed. When the L arm 304b-2 moves, the inner support arm 304b-4 will fit on the conical surface of the chuck 304a-2. With continuous advancement, the support arm 304b-4 will be squeezed and contracted by the conical surface. During the contraction, the gas pressure rod 304b-5 is compressed. When one end of the support arm 304b-4 moves to between the chuck 304a-2 and the movable disk 304a-3, it is not subject to limiting force. Therefore, the reaction force of the gas pressure rod 304b-5 drives the support arm 304b-4 to reset, so that one end of the support arm 304b-4 is against the plane side of the chuck 304a-2, thereby forming a clamping connection.

[0056] During disassembly: push the contact rod to drive the movable disk 304a-3 to move toward the support arm 304b-4. After the displacement, the outer side of the movable disk 304a-3 squeezes the support arm 304b-4 to compress the air pressure rod 304b-5 and complete the retraction. After the retraction, the outer side of the support arm 304b-4 fits against the outer side of the chuck 304a-2. At this time, the separation and disassembly can be completed under the action of the pulling disk 304b-1.

[0057] Furthermore, the driving member 304c includes a sleeve 304c-1 fixed to one side of the clamping fixing block 303, a movable rod 304c-2 passes through the internal axis of the sleeve 304c-1, the other end of the movable rod 304c-2 is fixed to the disc 304b-1, a pressing plate 304c-3 is fixedly sleeved on the outside of the movable rod 304c-2 in the sleeve 304c-1, and a spring 304c-4 is sleeved on the outside of the movable rod 304c-2 in the sleeve 304c-1.

[0058] Specifically, the outer end surface of the sleeve 304c-1 is provided with a spiral surface 304c-5, and the surface of the spiral surface 304c-5 is provided with limiting grooves 304c-6 at equal intervals. A channel 304c-7 extending to the sleeve 304c-1 is provided at the drop of the spiral surface 304c-5. A limiting rod 304c-8 is fixed to the outer side of the movable rod 304c-2 near the end. After the support arm 304b-4 is clamped into the plane side of the chuck 304a-2, the limiting rod 304c-8 is rotated, and the limiting rod 304c-8 will move along the spiral surface 304c-5. The slope of the effective spiral surface 304c-5 gradually increases, so the movable rod 304c-2 is pulled during the rotation process, and the movable rod 304c-2 pulls the disk 304b-1, so that the support arm 304b-4 is completely attached to the plane side of the chuck 304a-2. At this time, the limiting rod 304c-8 cannot rotate due to the distance limit, so it is directly stuck in the corresponding limiting groove 304c-6, that is, the clamping is completed. When releasing, the limiting rod 304c-8 is rotated in the opposite direction, and the clamping connection between the control touch rod and the support arm 304b-4 and the chuck 304a-2 can be removed;

[0059] Specifically, the mounting plate 301 is movably connected to the bottom support connection block 302 and the clamping fixing block 303 through a spacing adjustment component 305, which is used to adjust the spacing between the fan 1 201 or the fan 202 and the transformer. The spacing adjustment component 305 includes a strip-shaped through groove 305a provided on the mounting plate 301 and a bolt 305b fixed on the bottom support connection block 302. The bolt 305b is threadedly connected with a nut 305c. When installing, the bottom support connection block 302 is first installed on the cross arm 101 by screws. At this time, the bottom support connection block 302 has a certain load force, and the installation plate 301 is placed on the bottom support connection block 302, ensuring that the strip jump groove 305a passes through the bolt 305b, and further installing the clamping fixing block 303, and the clamping fixing block 303 is completely fixed to the cross arm 101 and the bottom support connection block 302 through the plug-in component 304, and then the installation plate 301 is pulled to move it to a suitable position, ensuring that the fan 1 201 and the fan 2 202 are at a suitable distance from the transformer, and finally fixed by the nut 305c;

[0060] The structure adopts a split structure, which is easy to disassemble and assemble, reduces the difficulty of installation, and has the effect of distance adjustment, so that fan 1 201 and fan 2 202 maintain a safe distance from the transformer, avoid affecting the magnetic field near the transformer, and ensure safety in use.

[0061] The rest of the structure is the same as that of Example 1.

[0062] Example 3

[0063] Reference Figure 7-9 , this embodiment is different from the above embodiment in that: the air-cooling heat dissipation device for transformers in this embodiment further includes: a shock absorbing part 400, which is arranged between the bottom of the mounting seat part 300 and the diagonal support 102, and is used to play a shock-resistant role;

[0064] The shock absorbing part 400 includes a telescopic support rod 401 and a flat plate 402. One end of the telescopic support rod 401 is rotatably connected to the bottom of the mounting plate 301. The flat plate 402 is fixed to the inner side of the diagonal support 102. The other end of the telescopic support rod 401 is elastically connected to the flat plate 402 through a buffer component 403.

[0065] Specifically, the telescopic support rod 401 is composed of multiple sections of steel pipes fastened by threads, which is convenient for self-assembly according to the length;

[0066] Furthermore, the buffer assembly 403 includes a connecting rod 403a, the top of which is connected to a fixed plate 403b, and the outer portion of the connecting rod 403a is sleeved with a damping member 403c fixed to the upper surface of the flat plate 402, and the outer portion of the connecting rod 403a is movably sleeved with a rotating shock-absorbing member 403d.

[0067] Specifically, the rotary shock-absorbing member 403d includes a collar 403d-1 rotatably connected to the bottom of the plate 402, fixed ears 403d-2 are arranged on both sides of the collar 403d-1, and fixed blocks 403d-3 are arranged on both sides of the fixed ears 403d-2, the two fixed blocks 403d-3 are fixed to the bottom of the plate 402, and an arc rod 403d-4 penetrating the fixed ears 403d-2 is connected between the two fixed blocks 403d-3, and a spring 2 403d-5 is sleeved on the outside of the arc rod 403d-4, and the collar 403d-1 is connected to the connecting rod 403a through a conversion member;

[0068] During shock absorption, the telescopic support rod 401 transmits the vibration to the connecting rod 403a. After the connecting rod 403a is stressed, it transmits the force downward to the damping member 403c. The damping member 403c performs preliminary buffering, and the force of continuous downward movement is converted into a rotational force through a conversion member. The conversion member includes a spiral groove 403d-6 opened inside the collar 403d-1 and a protrusion fixed on the connecting rod 403a. When moving downward, the protrusion moves in the spiral groove 403d-6 and forces the collar 403d-1 to rotate. When rotating, the kinetic energy is offset by two springs 403d-5, which effectively solves the vibration problem.

[0069] This structure converts the downward kinetic energy during vibration into rotational force, which will offset part of the vibration in the process. During the rotation process, it is necessary to stretch or squeeze the spring 403d-5 to further offset the kinetic energy generated by the vibration and prevent the vibration from being transmitted to the transformer, which will affect the structural stability of the transformer.

[0070] The rest of the structure is the same as that of Example 2.
