Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and more particularly to a dry-type transformer with a lead-out wire management structure. Background Art

[0002] Dry-type transformer is a kind of power transformer. Different from traditional transformers that rely on oil or other liquids as insulation or cooling medium, it adopts natural air cooling or forced air cooling. This kind of transformer is widely used in urban power grids, commercial buildings, industrial facilities and other occasions due to its simple structure, compact size, light weight, easy maintenance, no oil pollution risk and good environmental adaptability. It is an indispensable power conversion equipment in modern power systems.

[0003] Generally, a dry-type transformer is connected to an external control cabinet through multiple wire groups, each of which includes several wires. In the prior art, in order to avoid short circuits and maintenance difficulties caused by the entanglement of the wires, a wire management structure is installed to fix and organize the wires. For example, the publication number CN113421741A specifically discloses a transformer, including a wire management box, a wire winding block, a winding post, a wire trough, a rotating rod, a connecting rod, a screw rod I, a rotating ring, a sliding frame and a transformer. The upper end of the wire management box is provided with multiple wire entry holes, and multiple wire winding blocks are slidably connected to the wire management box. The multiple wire winding blocks are semi-cylindrical, and end covers are provided on the multiple wire winding blocks. End covers are provided on multiple winding posts, and multiple winding posts are fixedly connected to the wire management box.

[0004] Although the wire management structure set in the above-mentioned transformer has solved the problem of wire entanglement, there are still some shortcomings in actual use. For example, the wires are fixed side by side in the same junction box, the two wires are close to each other, and are only fixed and separated by thin-walled clamps. When one of the wires is short-circuited, the high temperature generated will affect the wires in adjacent positions, easily triggering a chain reaction of other wires; in addition, due to its integrated junction box method, the wires need to be arranged strictly according to the route planned by the wire management structure, and there are certain requirements on the length of the wires. For some shorter wires, they cannot be well adapted to the route set by the junction box. Therefore, it is necessary to provide a dry-type transformer with a wire management structure that has higher wire safety protection capabilities and better flexibility and adaptability during use.

[0037] Embodiment 1

[0038] Please refer to Figures 1 to 3A dry-type transformer with a lead-out wire management structure comprises: a dry-type transformer body 1, a control cabinet 2 and a base 3, wherein the dry-type transformer body 1 and the control cabinet 2 are both installed on the top of the base 3, the dry-type transformer body 1 and the control cabinet 2 are electrically connected through six wire groups, and each wire group is composed of a plurality of wires 5, and a wire management mechanism 4 having the same number as the wire groups is arranged between the dry-type transformer body 1 and the control cabinet 2, each wire management mechanism 4 is used to comb each wire group, and the wire management mechanism 4 is used to independently fix a plurality of wires 5 in the same wire group, so that the plurality of wires 5 in the same wire group are neatly and orderly distributed; the wire management mechanism 4 comprises a support portion and a wire installation portion, the support portion is connected to the base 3, the support portion is fixed to the base 3, and the wire installation portion is connected to the support portion, The support portion provides support for the wire installation portion, and the wire installation portion includes four junction box assemblies 41, and the four junction box assemblies 41 are linearly distributed on the support portion. The number of junction box assemblies 41 is the same as the number of wires 5 in the same wire group. The number of junction box assemblies 41 is not limited to four, and can be adjusted according to actual usage. The junction box assembly 41 is used to clamp and fix the wire 5 so that the wire 5 can be fixed in an independent installation environment along its direction. The support portion has the function of adjusting the preset route direction of the junction box assembly 41, and adjusting the preset route direction of the junction box assembly 41 to be consistent with the direction of the wire 5. Since the wires 5 between the dry-type transformer and the control cabinet 2 are mostly connected in a horizontal straight line, the junction box assembly 41 provided in the present invention is also a horizontal linear structure.

[0039] For details, please refer to Figure 3 and Fig. 9 In order to realize the function of supporting the wire installation part and adjusting the preset route direction of the junction box assembly 41, the present invention designs a support assembly 42, specifically: the support part is the support assembly 42, the support assembly 42 includes a fixed base plate 421, a support rod 422, a positioning block 423 and a fastening bolt 424, the fixed base plate 421 and the top of the base 3 are detachably installed, the bottom end of the support rod 422 is rotatably connected to the top of the fixed base plate 421, the junction box assembly 41 is connected to the support rod 422, the positioning block 423 is fixedly sleeved on the lower end of the support rod 422, the fastening bolt 424 is threadedly installed on the top of the positioning block 423, and the bottom end of the fastening bolt 424 passes through the bottom of the positioning block 423 and fits with the top of the fixed base plate 421.

[0040] It should be noted that when the above-mentioned wire management mechanism 4 is in use, the fixed bottom plate 421 is first fixed to the position corresponding to the wire group on the top of the base 3, and it can be fixed with bolts. Then, according to the direction of the wire 5, the direction of the preset route of the junction box assembly 41 is adjusted, that is, the angle of the junction box assembly 41 is adjusted, and the bottom end is separated from the fixed bottom plate 421 by rotating the fastening bolt 424, and the locking effect of the support rod 422 is released. Then, by rotating the support rod 422, the junction box assembly 41 follows the support rod 422 to rotate. When the angle of the junction box assembly 41 matches the direction of the wire 5, the fastening bolt 424 is rotated again to fix the support rod 422. Then, the wire 5 is first installed with the corresponding junction box assembly 41, and then the wiring end of the wire 5 is connected to the wiring terminal of the control cabinet 2.

[0041] In the above scheme, the wire installation portion provided by the present invention can be used to separately fix and manage multiple wires 5 of the same wire group by providing multiple independent junction box assemblies 41, so that each wire 5 maintains a safe distance, which is beneficial to avoid the chain reaction problem of the wires 5. By linearly arranging the junction box assembly 41 on the support portion and through the movement of the support portion, the preset route direction of the junction box assembly 41 can be adjusted to be consistent with the direction of the wire 5, so that each junction box assembly 41 corresponds to one wire 5, and can accurately match the direction of each wire 5, thereby reducing the requirements for the length of the wire 5, and improving the compatibility of the junction box assembly 41 and the wire 5, as well as its flexibility in use.

[0042] Please refer to Figures 3 to 8In order to realize independent clamping and fixing of the wire 5, the present invention sets up a specific structure of the junction box assembly 41, the junction box assembly 41 includes a junction box body 411 and a clamping member 413, both ends of the junction box body 411 are provided with a clamping groove 412 adapted to the wire 5, the junction box body 411 is a rectangular structure, the clamping member 413 is connected to the junction box body 411, and is used to clamp and fix the wire 5 in the junction box body 411. After the clamping member 413 clamps the wire 5, the opening of the junction box body 411 is blocked at the same time. The clamping member 413 includes a cover plate 4131, a sliding plate 4132, an unlocking rotating body 4133, a driving plate 4134, two clamping heads 4135, two supporting springs 4136 and two lifting blocks 4137. The cover plate 4131 is slidably mounted on the top of the junction box body 411, the sliding plate 4132 is slidably mounted on the bottom of the junction box body 411, the top of the sliding plate 4132 is fixed to one side of the cover plate 4131, and the unlocking rotating body 4133 is rotatably mounted on the junction box body. The bottom of 411, the outer side of the unlocking rotating body 4133 is connected with the internal thread of the sliding plate 4132, the driving plate 4134 is located on the side of the junction box body 411 away from the unlocking rotating body 4133, the bottom of the driving plate 4134 is fixed to the top of the sliding plate 4132, the driving plate 4134 is connected to one side of the connecting plate 431, and the two clamping heads 4135 are symmetrically arranged at both ends of the inside of the junction box body 411, and one side of the two clamping heads 4135 slides through the junction box body 4 11, and are respectively fixed to the two ends of the driving plate 4134, the clamping head 4135 is a U-shaped structure arranged horizontally, the inner side of the clamping head 4135 is provided with a protective layer, the inner bottom wall of the clamping groove 412 is higher than the inner top wall of the clamping head 4135, the support spring 4136 is fixedly installed between the sliding end of the clamping head 4135 and the terminal box body 411, the two lifting blocks 4137 are symmetrically fixedly installed at the two ends of the top of the cover plate 4131, and the upper end of the driving plate 4134 is provided with two An arc groove 4138 is adapted to the lifting block 4137. After the lifting block 4137 contacts the arc groove 4138, an upward force is generated on the driving plate 4134. The top of the lifting block 4137 is provided with a first inclined surface and a horizontal surface; the junction box body 411, the cover plate 4131 and the clamping head 4135 are all made of insulating materials, and the inner wall of the junction box body 411 is provided with a high-temperature resistant protective layer, which can prevent the wire 5 from burning the junction box body 411 after a short circuit, and avoid affecting other wires 5.

[0043] The use process of the above-mentioned junction box assembly 41 is as follows: when installing the wire 5, the junction box body 411 needs to be opened first. At this time, by rotating the unlocking rotating body 4133, the sliding plate 4132 can be driven to slide horizontally along the bottom of the junction box body 411, and the cover plate 4131 and the lifting block 4137 follow the sliding plate 4132 to slide horizontally along the top of the junction box body 411. When the first inclined surface of the lifting block 4137 contacts the arc groove 4138, as the sliding plate 4132 continues to slide, the lifting block 4137 can be driven to slide horizontally along the bottom of the junction box body 411. 4137 generates an upward thrust on the arc groove 4138, thereby pushing the driving plate 4134 upward, and the two clamping heads 4135 begin to move upward with the driving plate 4134, and simultaneously stretch the supporting spring 4136 connected thereto. When the first inclined surface of the lower position of the lifting block 4137 separates from the arc groove 4138, and the horizontal surface of the lifting block 4137 contacts the arc groove 4138, the driving plate 4134 is no longer subjected to the upward thrust. At this time, the two clamping heads 4135 also move up to the wiring The top position of the box body 411 is exposed to the outside by clamping the end of the wire 5 close to the dry-type transformer into the corresponding clamping groove 412, and then the wire 5 is clamped with the clamping ends of the two clamping heads 4135. After the installation, the wire 5 is temporarily in a straight state, and then, the unlocking rotating member is rotated in the reverse direction to drive the sliding plate 4132 and the cover plate 4131 to slide and reset together, and the driving plate 4134 and the clamping head 4135 are supported on the support spring 4 Under the action of the elastic force of 136, it moves down and resets synchronously. Before the clamping head 4135 moves down into the junction box body 411, the sliding plate 4132 will not contact the wire 5, so that there will be no interference between the clamping head 4135 and the cover plate 4131, until the cover plate 4131 completely blocks the top opening of the junction box body 411, and the installation of the wire 5 is completed. After that, the other terminal of the wire 5 can be connected to the terminal of the control cabinet 2. Repeat this operation until all the wires 5 are installed.

[0044] It should be noted that the junction box assembly 41 provided in the present invention is different from the fixing form of the existing junction box. When the cover plate 4131 is opened, the clamping head 4135 is simultaneously moved up to the top position of the junction box and directly exposed to the external environment. The two ends of the wire 5 can be quickly fixed to the clamping head 4135, which is more convenient to install than the traditional method of embedding it inside the junction box. In addition, by moving the clamping head 4135 downward to form a height difference with the clamping groove 412, the wire 5 is trapezoidal in shape, which also enhances the fixing effect of the wire 5 and makes it difficult to separate from the clamping head 4135. It can be seen that the junction box assembly 41 provided in the present invention not only realizes the independent installation and protection of the wire 5, but also makes it more convenient to install the wire 5 and has a better fixing effect.

[0045] Embodiment 2

[0046] In addition, please refer to Fig.10 Since there are many wires 5 to be installed, it is necessary to repeatedly open and close the junction box assembly 41, which is labor-intensive and the operation process is cumbersome. Therefore, in order to further speed up the installation of the wires 5, the present invention further improves the above scheme, specifically: the wire installation part also includes a connecting plate 431, and the connecting plate 431 is simultaneously connected to one side of the four driving plates 4134. By setting the connecting plate 431, the linkage effect of the four junction box assemblies 41 can be achieved. When one of the junction box assemblies 41 is opened or closed, the connecting plate 431 is connected to the connecting plate 431. The transmission function of the plate 431 can synchronously drive other junction box components 41 to move synchronously. In this way, there is no need to repeat the operation of the junction box component 41, which simplifies the original cumbersome operation and makes the installation faster. When installing the wires 5, it is only necessary to install all the wires 5 with the corresponding clamping heads 4135, and then close one of the junction box components 41, so that all the wires 5 can enter the junction box body 411 synchronously, making the junction box component 41 more convenient and trouble-free when using. At the same time, it also brings great convenience for opening and closing for subsequent maintenance operations.

[0047] Embodiment 3

[0048] Please refer to Fig.11 , the transformer body 1 itself fails and needs to be disassembled. When performing maintenance work on it separately, it is necessary to separate all the wires 5 from the wiring terminals of the control cabinet 2. However, the process of separating them one by one is cumbersome and time-consuming. They need to be installed one by one in the future, which brings great inconvenience to the maintenance work of the staff. Therefore, in order to solve this problem, the present invention continues to optimize the above scheme, specifically: the junction box assembly 41 also includes a fixing member 414, which is used to fix the wiring terminal of the wire 5 to the wiring terminal 6 of the control cabinet 2, and the fixing member 414 includes a fixing A buckle 4141, a fixing plate 4142 and a connecting spring 4143, a slide groove 4144 is provided on one side of the driving plate 4134, one end of the fixing plate 4142 is slidably connected to the slide groove 4144, the connecting spring 4143 is fixed between the fixing plate 4142 and the junction box body 411, and one end of the fixing plate 4142 away from the driving plate 4134 is detachably connected to the fixing buckle 4141, and the fixing buckle 4141 is used to fix the wiring terminal of the wire 5 to the wiring terminal 6 of the control cabinet 2. A second inclined surface is also provided on the top of the lifting block 4137, the second inclined surface is connected to the horizontal surface, and the second inclined surface is higher than the first inclined surface.

[0049] When the fixing member 414 is in use, it is necessary to separate the wiring terminals of all the wires 5 from the wiring terminals 6 of the control cabinet 2. First, one of the terminal box assemblies 41 is adjusted to the open state so that the cover plate 4131 is completely opened. Due to the setting of the slide groove 4144, the driving plate 4134 will not drive the fixing plate 4142 to move upward during the previous upward movement, so that the wires 5 and the wiring terminals of the control cabinet 2 remain connected. Afterwards, the unlocking rotating body 4133 is continuously rotated to make the sliding plate 4132 drive the cover plate 4131 to continue to slide. When the second inclined surface at the top of the lifting block 4137 contacts the arc groove 4138, the belt The movable plate 4134 generates an upward thrust. At this time, the inner bottom wall of the slide groove 4144 has contacted with the fixed plate 4142, so that the fixed plate 4142 and the fixed buckle 4141 can move up together with the driving plate 4134, and the connecting spring 4143 is synchronously stretched until the fixed buckle 4141 is separated from the terminal of the wire 5. Under the driving action of the connecting plate 431, the other fixed buckles 4141 also synchronously complete the separation action, and the clamping head 4135 is also further lifted in this process. During the further upward movement of the clamping head 4135, the wire 5 can be driven to continue to move upward, so that the wire 5 can be automatically separated from the clamping groove 412.

[0050] It should be noted that the present invention further provides a fixing member 414, which is used in conjunction with the clamping member 413 to achieve a synchronous separation function of the wiring terminals of multiple wires 5 and the wiring terminals 6 of the control cabinet 2. When the dry-type transformer body 1 needs to be disassembled and repaired separately, there is no need to disassemble and assemble the wires 5 one by one, which simplifies the disassembly and assembly operation of the wires 5, thereby facilitating the maintenance work of the staff. In addition, in the process of disassembling the wiring terminals of the wires 5, the separation of the wires 5 and the clamping slots 412 is also achieved synchronously, without the need for manual separation operation again, which further simplifies the disassembly and assembly steps of the wires 5.

[0052] Please refer to Figure 12 to Figure 14In order to further adapt to the distribution of the wires 5 and make the junction box assembly 41 and the wires 5 accurately match each other, the present invention continues to optimize on the basis of the above scheme, specifically: the support rod 422 is a threaded rod, a composite sleeve 425 is fixedly installed on one side of the junction box body 411, and the composite sleeve 425 is sleeved on the outer side of the support rod 422. The composite sleeve 425 includes a sliding section and a rotating section. The sliding section is slidably connected to the outer side of the support rod 422, and the rotating section is threadedly connected to the outer side of the support rod 422. A groove is also provided on the outer side of the support rod 422, and a protrusion adapted to the groove is provided on the inner side of the sliding end, so that the composite sleeve 425 can move up and down along the outer side of the support rod 422. A moving groove 432 is provided on one side of the connecting plate 431, and a positioning bolt 433 is threadedly installed on one side of the driving plate 4134. The outer side of the stud of the positioning bolt 433 is slidably connected to the moving groove 432, and one side of the nut of the positioning bolt 433 is in contact with one side of the driving plate 4134.

[0053] During the installation of the wire 5 and the junction box assembly 41, if the height of the corresponding wire 5 does not match the junction box assembly 41, it is necessary to first rotate the positioning bolt 433 to release its fixing effect on the connecting plate 431, and then the rotating section of the composite sleeve 425 can be rotated so that it can move along the outside of the support rod 422, thereby driving the corresponding junction box assembly 41 to move up and down until it is consistent with the height of the corresponding wire 5, and then the rotation of the composite sleeve 425 can be stopped. Since the sliding section of the composite sleeve 425 is threadedly connected to the support rod 422, it will no longer move after stopping rotation, thereby keeping the junction box assembly 41 fixed. Finally, the fastening bolt 424 is rotated to keep the connecting plate 431 and the driving plate 4134 fixed, thereby realizing the position adjustment function of the junction box assembly 41, and further increasing the adaptability of the junction box assembly 41 and the wire 5 to meet the usage requirements under different conditions.

[0054] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
