Description

Technical Field

[0001] The utility model relates to the technical field of three-dimensional wound core transformers, in particular to a novel three-dimensional wound core transformer assembly. Background Art

[0002] With the rapid increase of urban electricity consumption, more and more power distribution rooms need to be built in residential areas and densely populated areas, which brings many transformer noise nuisance problems. With the improvement of people's quality of life and the continuous enhancement of environmental protection awareness, low-noise transformers are becoming more and more popular.

[0003] Announcement No. CN 217640949 U discloses a three-dimensional wound core transformer and its mounting assembly, the mounting assembly includes a lower frame, a central support, a peripheral support and a suspension. The central support is arranged in the lower frame, one end of the peripheral support is connected to the lower frame, and the peripheral support and the central support are arranged at intervals, so that the core can be arranged between the central support and the peripheral support. The suspension is passed through the core so that one end of the suspension is connected to the central support and the other end is connected to the other end of the peripheral support, so that the suspension is supported on the upper iron yoke of the core, so that the core is separated from the lower frame or the contact is reduced, the noise propagation path between the core and the lower frame is blocked or weakened, and the noise generated by the core of the three-dimensional wound core transformer during operation is effectively reduced. The structure of the above-mentioned mounting assembly is simple, which avoids the increase of cost, but it has certain defects.

[0004] The assembly of the three-dimensional wound core transformer mentioned above is too complicated, and bolts need to be used one by one for docking and installation, which makes the installation of the three-dimensional wound core transformer assembly too complicated and not convenient enough, and the disassembly is not convenient and fast enough. In addition, the existing three-dimensional wound core transformer clamp structure adopts welding. In order to ensure the structural strength of the clamp, the clamp adopts overall full welding. During the welding process, the clamp is prone to deformation due to high temperature, resulting in a decrease in the accuracy of the clamp, which cannot meet the installation size required by the transformer. In addition, the welding process is difficult to operate, the processing efficiency is low, and it cannot be quickly mass-produced. For this reason, we have proposed a new three-dimensional wound core transformer assembly to solve the above problems. Utility Model Content

The device installs the three-dimensional iron core 1 and the coil 2 at a height between the base 3 and the top plate 5 through the locking component and the adjustment component, thereby reducing the complexity of installing the three-dimensional iron core 1 and the coil 2;

[0023] Furthermore, the locking assembly includes a protrusion 6, which is fixedly mounted on the upper end of the vertical rod 4, a through hole 7 is provided in the top plate 5, the protrusion 6 is movably inserted in the through hole 7, and movable grooves 8 are symmetrically provided in the protrusion 6. Springs 9 are installed in the two groups of movable grooves 8, and limiting blocks 10 are movably installed at the openings of the two groups of movable grooves 8. Limiting grooves 11 are symmetrically provided in the top plate 5, and the two groups of limiting blocks 10 are movably inserted in the two groups of limiting grooves 11. Three groups of threaded holes 17 are provided on the base 3 and the top plate 5, and three groups of long bolts 18 are movably inserted in the six groups of threaded holes 17. This structure places the three-dimensional iron core 1 and the coil 2 on the base 3, and fixes the top plate 5 on the top plate 5. The two groups of limiting blocks 10 are movably inserted in the two groups of limiting grooves 11, so that the top plate 5 and the base 3 can be preliminarily connected through the vertical rod 4, and then the three groups of long bolts 18 are used to fix the base 3 and the top plate 5, thereby fixing the three-dimensional iron core 1 and the coil 2.

[0024] Furthermore, both sides of the upper sides of the two groups of limit blocks 10 are inclined, and the cross-sections of the two groups of limit blocks 10 are triangular. According to the shapes of the two groups of limit blocks 10, this structure allows the two groups of limit blocks 10 to be squeezed and inserted into the two groups of limit grooves 11 or slide out of the two groups of limit grooves 11.

After the three-dimensional iron core 1 is clamped and limited by the three sets of clamping plates 13, the protective shell 16 is movably inserted into the groove 15 on the base 3, and then the top plate 5 is placed on the upper side of the three-dimensional iron core 1, and the protrusion 6 at the upper end of the vertical rod 4 is movably inserted into the through hole 7 on the top plate 5, and the two sets of limit blocks 10 in the two sets of movable grooves 8 pop out under the action of the restorative elastic force of the two sets of springs 9. After the two sets of limit blocks 10 pop out, they are movably inserted into the two sets of limit grooves 11, and the top plate 5 is connected to the base 3 through the vertical rod 4 and the protrusion 6. The three sets of long bolts 18 are movably inserted into the six sets of threaded holes 17, and the base 3 and the top plate 5 are fixedly connected.
