Description

Technical Field

[0001] This utility model relates to the field of transformer technology, and more specifically, to a compact transformer that is easy to install. Background Technology

[0002] Dry-type transformers are generally used indoors. Their internal components, including core winding assemblies and cooling assemblies, are relatively large. Therefore, these components are compactly connected as a single unit. During the manufacturing process, the overall dimensions of the internal components must be measured to allow for adequate heat dissipation and maintenance space, resulting in a suitable compact casing. In existing technologies, the installation of this compact casing involves assembling separately cut top, side, and bottom plates around the internal components. The panels are quite large, typically requiring two installers. Furthermore, installing the top plate requires climbing, adding to the installation difficulty. Therefore, a more easily installed compact transformer is proposed. Utility Model Content

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] See Figures 1 to 9 This utility model discloses a compact transformer that is easy to install. It includes an internal component 5 such as a core winding assembly and a cooling assembly, as well as a bottom frame assembly 3, an upper module assembly 11, and a lower module assembly 21. Based on the size of the internal component 5, the width and length are increased by 50cm. The total height of the upper module assembly 11 and the lower module assembly 21 is increased by 70cm based on the size of the internal component 5. This achieves the minimum size of the internal component 5's outer shell while meeting the requirements for heat dissipation, maintenance, and safety distance. During installation, the assembled core winding assembly and cooling assembly are hoisted to the middle position of the bottom frame assembly 3 and fixed by the first fixing bolt. The lower module assembly 21 is distributed around the bottom frame assembly 3. The third side plate 211 and the fourth side plate 212 are attached to the edges of any two adjacent sides of the bottom frame assembly 3. The third side plate 211 (or the fourth side plate 212) of the lower module assembly 21 is parallel to and corresponds to the fourth side plate 212 (or the third side plate 211) of the adjacent lower module assembly 21. The third side plate 211 and the fourth side plate 212 are adjusted by the tensioning member 4 so that the adjacent sides of the third side plate 211 (or the fourth side plate 212) and the fourth side plate 212 (or the third side plate 211) in the two adjacent lower module components 21 are fitted together to form an enclosed lower frame 2.

[0031] The upper module component 11 is provided with a first connector 12, and the lower module component 21 is provided with a second connector. The first connector 12 and the second connector are connected to each other, so that the upper module component 11 and the lower module component 21 correspond to each other, that is, the bottom end of the first side plate 111 and the top end of the third side plate 211, and the bottom end of the second side plate 112 and the top end of the fourth side plate 212 are abutted and fitted together. When the upper module component 11 and the lower module component 21 are distributed vertically, the adjacent edges of adjacent upper module components 11 naturally fit together, that is, the adjacent edges of the first side plate 111 of the upper module component 11 and the adjacent second side plate 112 of the upper module component 11 are correspondingly fitted and connected, splicing together to form an enclosed upper frame 1. At this time, the top plate 113 is naturally spliced ​​together. Compared with the prior art, the volume and size of the bottom frame component 3, the upper module component 11, and the lower module component 21 are reasonable, and one person can install them. Moreover, the connection of each component does not require climbing, making it easier to install.

[0032] The first side plate 111 and the second side plate 112 are vertically connected by the first corner bracket 114. Any two plates between the third side plate 211, the fourth side plate 212 and the top plate 113 are vertically connected to each other by the second corner bracket 213. The upper and lower module components minimize the space occupied by orthogonal layout, which meets the "compact" design requirements.

[0033] The first connector 12 includes a triangular connecting plate 121 and a positioning sleeve 122. The triangular connecting plate 121 is disposed between the first side plate 111 and the second side plate 112. The triangular connecting plate 121 has a connecting hole 1211. The positioning sleeve 122 is welded into the connecting hole 1211. The second connector includes a triangular connecting plate 22. The triangular connecting plate 22 is disposed between the third side plate 211 and the fourth side plate 212. The triangular connecting plate 22 has a positioning hole 221. After the positioning sleeve 122 is fitted into the positioning hole 221, the locking bolt 13 is placed in the positioning sleeve 122. The locking bolt 13, together with the nut 14, restricts the triangular connecting plate 121 and the triangular connecting plate 22 against each other.

[0034] Any upper module component 11 is hinged to the first pin tube 17, and the adjacent upper module component 11 is fixedly connected to the second pin tube 16. The openings of the two second pin tubes 16 are opposite each other and spaced apart. When the first pin tube 17 rotates to one side of the adjacent upper module component 11, the openings of the two second pin tubes 16 are respectively aligned with the openings of the two ends of the first pin tube 17, and the shaft pin 6 is simultaneously inserted into the first pin tube 17 and the second pin tube 16, so that the two upper module components 11 are connected.

[0035] The tensioning component 4 includes a telescopic sleeve 41 and a screw 42. The screw 42 is disposed inside the telescopic sleeve 41. A first limiting plate 44 is disposed at the end of the telescopic sleeve 41 furthest from the screw 42, and a second limiting plate 45 is disposed at the end of the screw 42 furthest from the telescopic sleeve 41. A first limiting groove 23 and a second limiting groove 24 are respectively disposed on the lower module assembly 21. The first limiting groove 23 (or the second limiting groove 24) of any lower module assembly 21 and the second limiting groove 24 (or the first limiting groove 23) of the adjacent lower module assembly 21 are arranged opposite to each other so that the first limiting plate 44 and the second limiting plate 45 can be fitted simultaneously. In this embodiment, the first limiting plate 44 and the second limiting plate 45 are circular plates, and the first limiting groove 23 and the second limiting groove 24 are corresponding circular grooves, which are fitted and connected to the circular plates. The telescopic sleeve 41 is rotatably connected to the threaded tube 43. The threaded tube 43 and the telescopic sleeve 41 are internally connected. The threaded tube 43 is threadedly connected to the screw 42. In use, the threaded tube 43 is rotated to adjust the telescopic length of the screw 42 and the telescopic sleeve 41 so that the length from the first limiting plate 44 to the second limiting plate 45 is close to the distance from the first limiting groove 23 to the second limiting groove 24. Then, the first limiting plate 44 and the second limiting plate 45 are placed in the first limiting groove 23 and the second limiting groove 24 respectively. The screw 42 is then further adjusted so that the adjacent edges of the first side plate 111 and the second side plate 112 of the adjacent lower module assembly 21 are pressed together, and the plate surfaces of the first side plate 111 and the second side plate 112 are more in line with the edge of the bottom frame assembly 3.

[0036] The bottom frame assembly 3 includes a bottom frame body 31 and a heat sink 33. The bottom frame body 31 includes a first aluminum profile 311 and a second aluminum profile 312. The first aluminum profiles 311 are spaced apart side by side and connected by the second aluminum profile 312. The first aluminum profile 311 is provided with a first channel 3111 and a third channel 3112. The second aluminum profile 312 is provided with a second channel 3121 and a fourth channel 3122. The heat sink 33 is embedded in the first channel 3111 between adjacent bottom frames. The heat sink 33 connects the two bottom frames into one unit. The heat sink 33 is a louvered heat sink 33. The base of the internal assembly 5 is provided with a first fixing bolt, which is fixed in the second channel 3121. A support leg 32 is installed below the second aluminum profile 312. Connecting brackets 34 are installed on both sides of the support leg 32. A third fixing bolt is installed on each connecting bracket 34 and fixed within the fourth channel 3122. The end of the support leg 32 that contacts the ground is flush with the bottom end of the lower module assembly 21, providing a heat dissipation space between the bottom frame assembly 3 and the ground. A rubber pad 35, with a thickness greater than 5cm, is installed at the end of the support leg 32 that contacts the ground to reduce vibration transmission. A second fixing bolt 7 is installed on the lower module assembly 21 and fixed within the third channel 3112.

[0037] The upper module component 11 is also provided with an installation detection window 1111, which enables the installation of the upper module component 11 and the lower module component 21, and allows for timely checking of the status of the internal component 5.

[0038] During installation, first, the third side plate 211 and the fourth side plate 212 of the lower module assembly 21 are attached to the edge of the bottom frame assembly 3. The adjacent lower module assemblies 21 are then tightened using the tensioning member 4 until they form the lower frame 2. Next, the upper module assembly 11 is placed on top of each lower module assembly 21 by engaging the positioning sleeve 122 with the positioning hole 221 of the lower module assembly 21. The installation inspection window 1111 is opened, and the upper module assembly 11 and lower module assembly 21 are secured with locking bolts 13 and nuts 14. Once the upper module assemblies 11 are correctly positioned, the upper frame 1 is naturally formed. Finally, shaft pins 6 are inserted into the first pin tube 17 and the second pin tube 16 of two adjacent upper module assemblies 11 to connect them. For maintenance, the corresponding upper module assembly 11 and lower module assembly 21 can be disassembled according to the location of the maintenance. The disassembly principle is simple, easy to operate, and does not affect the connection of other module assemblies.

[0039] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
