[0002] In order to meet the market demand for monitoring the load condition of a transformer at any time to ensure the safe operation of the transformer, manufacturers often correspondingly set current transformers at the high-voltage side position of box-type transformers, such as intelligent box-type transformers of 35 kV and below. The larger the capacity of the current transformer, the larger its external dimensions and weight. The large-capacity current transformer has the advantages of higher detection accuracy and smaller measurement error.
[0003] However, in the existing box-type transformers, the current transformers are generally arranged on one side in the width direction of the transformer body. A lead sleeve is arranged on the outer side of the box wall, and the current transformer and the lead sleeve are correspondingly arranged on the inner side of the box wall. The two end faces of the current transformer are clamped by pressing plates and fixedly connected to the box wall through the pressing plates. However, if the thickness dimension of the installed current transformer is too large, it will cause the width dimension of the transformer body to be too large to be installed in a container, affecting the transportation of the entire box-type transformer. In addition, since the two end faces of the current transformer respectively abut against the pressing plates, the flow space of the transformer oil around the current transformer is small, so that the fluidity of the transformer oil flowing through the current transformer decreases, resulting in the heat generated when the current transformer works cannot be effectively reduced by the transformer oil, shortening the service life of the current transformer and affecting the normal use of the box-type transformer.

[0030] The present utility model provides an installation structure for a current transformer.
[0031] In an embodiment of the present utility model, as Figure 1 shown, the installation structure for the current transformer is used to install the current transformer of the transformer body, and includes a fastening structure 1 and a support structure 2. The support structure 2 is disposed at the bottom of the fastening structure 1 to support the fastening structure 1 on the top of the transformer body, and the current transformer is disposed within the fastening structure 1;
[0032] Among them, the fastening structure 1 includes a limiting member 11, a clamping plate 12, a separating member 13, and a first connection assembly 14; a plurality of limiting members 11 are distributed on the outer periphery of the current transformer to limit the position of the current transformer in the horizontal direction; both end faces of the current transformer along the height direction are respectively partially abutted against the separating member 13, and the side of the separating member 13 away from the current transformer is abutted against the clamping plate 12, so that an oil flow channel 15 is formed at an interval between the end face of the current transformer and the clamping plate 12; the limiting member 11, the clamping plate 12, and the separating member 13 are connected and fixed by the first connection assembly 14.
[0033] The utility model erects the fastening structure 1 on the top of the transformer body by arranging the supporting structure 2, which can be used to install current transformers with larger thickness dimensions, avoiding the situation that the thickness dimension of the current transformer is too large, resulting in an oversized width dimension of the transformer body and making it impossible to be installed in a container, so that the box-type transformer can be transported normally. The limit pieces 11 are distributed on the outer periphery of the current transformer, and the limit pieces 11 play a role in restricting the position of the current transformer in the horizontal direction; both end faces of the current transformer along the height direction are respectively partially abutted against the partition piece 13, and one side of the partition piece 13 away from the current transformer is abutted against the clamping plate 12, so that an oil flow channel 15 is formed at an interval between the end face of the current transformer and the clamping plate 12, avoiding the direct abutment of both end faces of the current transformer along the height direction against the clamping plate 12. The transformer oil can flow into the oil flow channel 15, increasing the flow space of the transformer oil around the current transformer, improving the fluidity of the transformer oil flowing through the current transformer, thereby effectively reducing the heat generated when the current transformer works, achieving the heat dissipation effect, prolonging the service life of the current transformer, and enabling the box-type transformer to operate normally. It solves the problems that the current transformer with a larger thickness dimension affects the transportation of the entire box-type transformer and the small flow space and low fluidity of the transformer oil around the current transformer result in the inability to reduce the heat of the current transformer.
[0034] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, the clamping plate 12 is provided with a through hole 121, and the center of the through hole 121 corresponds to the center of the inner hole 3 of the current transformer.
[0035] After the current transformer is installed on the top of the transformer body, a high-voltage lead 4 needs to be configured. One end of the high-voltage lead 4 is connected to the high-voltage side bushing 5, and the other end of the high-voltage lead 4 is connected to the load switch 6. At this time, the clamping plate 12 is provided with a through hole 121, and the center of the through hole 121 corresponds to the center of the inner hole 3 of the current transformer, which can facilitate the configuration of the high-voltage lead 4, so that the high-voltage lead 4 can pass through the through hole 121 and the inner hole 3 of the current transformer and be connected to the high-voltage side bushing 5 arranged outside the box wall of the box-type transformer, improving the assembly efficiency.
[0036] Preferably, the diameter of the through hole 121 of the clamping plate 12 at the bottom is the same as the diameter of the inner hole 3 of the current transformer. This not only facilitates the assembly of the high-voltage lead 4 but also increases the flow space of the transformer oil, enabling the heat generated by the current transformer to be transferred to the transformer oil faster and improving the heat dissipation effect.
[0037] Specifically, the number of through holes 121 of the clamping plate 12 is the same as the number of current transformers.
[0038] Please refer to Figure 1 and Figure 2, in an embodiment of the present application, the number of the separators 13 is twice that of the limiters 11, and two ends of each limiter 11 in the height direction are in butt joint with the separators 13 in one-to-one correspondence; the support structure 2 includes a first cross bar 21, and the first cross bar 21 is arranged under the bottom clamping plate 12 along the length direction of the clamping plate 12;
[0039] The first connection assembly 14 includes a first screw 141 and a first nut 142.

[0040] The number of the separators 13 is twice that of the limiters 11, and two ends of each limiter 11 in the height direction are in butt joint with the separators 13 in one-to-one correspondence, so that the position of the current transformer can be limited between the limiter 11 and the separator 13. The first cross bar 21 is arranged under the bottom clamping plate 12 along the length direction of the clamping plate 12, which can play a role in supporting the fastening structure 1. The first screw 141 in the first connection assembly 14 connects the limiter 11, the two clamping plates 12, the separator 13 and the first cross bar 21, and both ends of the first screw 141 are connected to the first nut 142 respectively, so as to press and fix the current transformer in the fastening structure 1 and limit the movement of the current transformer in the X and Y directions.
[0041] Preferably, the first connection assembly 14 is made of nylon material. The first connection assembly 14 has excellent corrosion resistance, wear resistance and insulation performance, and a long service life, which can ensure the insulation performance of the connection part, ensure that the current transformer will not cause safety problems due to electrical factors during use, and meet the high insulation requirements of the box-type transformer.
[0042] Specifically, the limiter 11, the clamping plate 12, the separator 13 and the first cross bar 21 are all provided with mounting holes. The first screw 141 sequentially passes through the mounting holes of the first cross bar 21, the lower clamping plate 12, the lower separator 13, the limiter 11, the upper separator 13 and the upper clamping plate 12, and then the first nut 142 is arranged at both ends of the first screw 141 and tightened and fixed.

[0044] The first horizontal bar 21, the vertical bar 22, the fixing bracket 23 and the second horizontal bar 24 together form a stable frame structure, enabling the support structure 2 to have a high load-bearing capacity. Thus, the utility model has high structural stability and can be used to install current transformers with larger thickness dimensions.
[0045] Specifically, the first horizontal bar 21, the vertical bar 22, the fixing bracket 23 and the second horizontal bar 24 are all provided with a plurality of mounting holes for connecting and fixing with other components. Preferably, the first horizontal bar 21 and the vertical bar 22 are connected and fixed through a second connecting component; the vertical bar 22 and the second horizontal bar 24 are connected and fixed through a second connecting component; the clamping plate 12, the first horizontal bar 21 and the second horizontal bar 24 at the bottom are connected and fixed through a second connecting component.

Preferably, the vertical bar 22 and the fixing bracket 23 are connected and fixed through a third connecting component. The third connecting component is made of metal material, which is convenient for installation and disassembly and is conducive to the maintenance of the utility model. The third connecting component includes a bolt and a third nut. One end of the bolt passes through the mounting holes of the vertical bar 22 and the fixing bracket 23 in sequence and is connected to the third nut.
[0046] Preferably, a part of the second horizontal bar 24 can be connected to both the first horizontal bar 21 and the second horizontal bar 24 simultaneously, which can greatly improve the structural stability of the utility model.
[0047] Optionally, according to the actual production situation, the sizes of several second horizontal bars 24 can be the same or different, and the sizes of the second horizontal bars 24 can be the same or different from those of the first horizontal bar 21. For example, the size of the second horizontal bar 24 connected to the vertical bar 22 can be larger than that of the second horizontal bar 24 not connected to the vertical bar 22.
[0048] Please refer to Figure 1 and Figure 3 , in an embodiment of the present application, the fixing bracket 23 includes a vertical plate 231 and a reinforcing plate 232. One end of the vertical plate 231 is connected to the vertical bar 22, and the reinforcing plate 232 is inclinedly installed at the other end of the vertical plate 231. The end face of the vertical plate 231 far from the vertical bar 22 and the end face of the reinforcing plate 232 far from the vertical bar 22 are flush.
[0049] The fixing bracket 23 can be used to install the present utility model on the top of the transformer body. The vertical plate 231 is connected to the vertical strip 22. By obliquely arranging the reinforcing plate 232, a triangular fixing structure is formed between the vertical plate 231 and the reinforcing plate 232, increasing the structural stability and load-bearing capacity of the fixing bracket 23, and ensuring that the present utility model can be stably installed on the top of the transformer body. The end surfaces of the end of the vertical plate 231 away from the vertical strip 22 and the end of the reinforcing plate 232 away from the vertical strip 22 are flush, which further facilitates the installation of the present utility model.
[0050] Specifically, the fixing bracket 23 is welded to the high-voltage side clamp and the low-voltage side clamp of the transformer body by welding.
[0051] Please refer to Figure 3 , in an embodiment of the present application, the reinforcing plate 232 and the vertical strip 22 are located on the same side or different sides of the vertical plate 231.
[0052] It depends on the specific production scenario and requirements. Whether the reinforcing plate 232 and the vertical strip 22 are located on the same side or different sides of the vertical plate 231, it can ensure that the fixing bracket 23 maintains a stable and reliable state in the overall structure, so that the present utility model has high structural stability.
[0053] Please refer to Figure 1 and Figure 3 , in an embodiment of the present application, the vertical strips 22 are symmetrically distributed along the length direction of the clamping plate 12.
[0054] The vertical strips 22 being symmetrically distributed along the length direction of the clamping plate 12 can make it more convenient to install the present utility model on the top of the transformer body, improving the practicability and the aesthetic appearance of the overall structure. It can be determined according to the actual production situation, and the vertical strips 22 symmetrically distributed along the length direction of the clamping plate 12 can be arranged on the left or right side of the first horizontal strip 21.

[0056] The surface of the limiting member 11 corresponding to the current transformer is set as a plane, and the plane is tangent to the side surface of the current transformer. The advantages of such a setting are: it can ensure that the limiting member 11 can limit the position of the current transformer in the horizontal direction, playing a limiting role, and at the same time, it can also provide a larger flow space for the transformer oil, ensuring the fluidity of the transformer oil, so as to take away more heat generated during the operation of the current transformer and achieve a heat dissipation effect.
[0057] Preferably, the limiting member 11 is in the shape of a straight prism. The limiting member 11 in the shape of a straight prism can improve the aesthetic appearance of the present utility model.
[0058] Please refer to Figure 1 and Figure 2 , in an embodiment of the present application, both end faces of the current transformer along the height direction are respectively connected to 4 partition members 13, and the 4 partition members 13 located on the same side of the current transformer are symmetrically distributed along the width direction of the clamping plate 12.
[0059] Both end faces of the current transformer along the height direction are respectively connected to 4 partition members 13, and the 4 partition members 13 located on the same side are symmetrically distributed along the width direction of the clamping plate 12. Such a setting can further limit the movement of the current transformer in the X and Y directions, thereby improving the position stability of the current transformer. At this time, both end faces of 1 current transformer along the height direction are fixed by 8 partition members 13 and 4 limiting members 11. In order to reduce the number of parts and improve the installation efficiency, when the number of current transformers is 2 or more, adjacent current transformers can share the partition members 13.
[0060] Preferably, the number of current transformers is 3.
[0061] Please refer to Figure 4 and Figure 5 , the present utility model also proposes a box-type transformer, including the above-mentioned current transformer installation structure.
[0062] When using the above-mentioned current transformer installation structure in a box-type transformer, the current transformer installation structure is installed on the top of the transformer body, avoiding the situation that a current transformer with a large thickness dimension is installed inside the box wall, resulting in an excessive width dimension of the transformer body and being unable to be installed in a container, thus affecting the transportation of the box-type transformer.
[0063] The installation process of the present utility model on the top of the transformer body is as follows:
[0064] The number of current transformers is 3. First, install the support structure 2 on the high-voltage side clamp and the low-voltage side clamp on the top of the transformer body. Then, install the fastening structure 1 on the support structure 2. Both end faces of the 3 current transformers along the height direction first partially abut against the partition members 13 respectively, and then the partition members 13 abut against the clamping plate 12. Install the limiting members 11 on the outer periphery of the current transformers, and use the first connection assembly 14 to connect and fix the limiting members 11, the clamping plate 12, and the partition members 13. Finally, place the current transformers in the fastening structure 1. After the installation of the current transformers is completed, configure the high-voltage lead 4.
