Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a reactor pull plate structure. Background Art

[0002] At present, in the field of reactor manufacturing technology, there are many types of reactors, and the effects they play are also different. However, the structure of the reactor body is roughly the same. The reactor pull plate is an indispensable and important component of the reactor itself. Its function is to tighten and fix the reactor itself.

[0003] Most of the existing reactor pull plates adopt distributed pull plates. If distributed pull plates are used for fixing, it is difficult to ensure the verticality of the reactor pull plates, which will cause the discus to be placed non-vertically during the process of stacking the discus, affecting the fastening strength of the iron core. Utility Model Content

[0004] The utility model provides a reactor pull plate structure to solve the technical problem that the prior art is difficult to ensure the verticality of the reactor pull plate, resulting in non-vertical placement of the discus during the disc stacking process, which affects the fastening strength of the iron core.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A reactor pull plate structure provided in the present application includes a pull plate body, the pull plate body includes a horizontal connecting part, vertical connecting parts are provided at both ends and the middle of the horizontal connecting part, an elliptical hole is provided at the end of the vertical connecting part away from the horizontal connecting part, and three circular holes are distributed in sequence on the horizontal connecting part along the horizontal direction of the horizontal connecting part, and the center line of the elliptical hole and the circular hole are located on the same straight line.

[0007] Furthermore, the horizontal connection part is installed on the lower iron yoke of the reactor core, and the end of the vertical connection part with the elliptical hole is installed on the upper iron yoke of the reactor core, and the discus of the reactor core is located between the upper iron yoke and the lower iron yoke.

[0008] Furthermore, the horizontal connection part is bolted to the outer side surface of the lower iron yoke through a circular hole, and the vertical connection part is bolted to the outer side surface of the upper iron yoke through an elliptical hole.

[0009] Furthermore, the vertical diameter of the elliptical hole is larger than the horizontal diameter, which is convenient for installation and manual adjustment of inductance. By adding or removing an iron sheet on the core of the reactor, the length of the magnetic circuit can be changed, thereby changing the inductance value.

[0010] Furthermore, the upper edge of the horizontal connecting portion is lower than the upper edge of the lower iron yoke.

[0011] Beneficial effects achieved by the utility model:

[0012] (1) The reactor pull plate structure provided by the utility model makes the connection between the pull plate and the reactor core simpler and faster through the design of elliptical holes and circular holes. The diameter of the elliptical hole in the vertical direction is larger than the diameter in the horizontal direction, which not only facilitates the insertion of bolts during installation, but also allows fine-tuning after installation, thereby improving installation efficiency and convenience. The design of the elliptical hole allows a certain amount of room for movement in the connection between the pull plate and the upper iron yoke. By manually adjusting or adding / removing iron sheets, the magnetic circuit length can be easily changed, thereby changing the inductance value. This design greatly improves the flexibility and adaptability of the reactor, enabling it to adapt to different working environments and power requirements.

[0013] (2) The pull plate structure of the reactor provided by the utility model adopts a design that combines a horizontal connection part and a vertical connection part. The stability and reliability of the pull plate structure are enhanced through a reasonable layout and connection method. At the same time, the upper edge of the horizontal connection part is lower than the upper edge of the lower iron yoke. This design helps to reduce the deformation and displacement of the pull plate when it is subjected to force, thereby ensuring the overall stability and safety of the reactor.

[0023] In a specific embodiment, the horizontal connecting part 11 is installed on the lower iron yoke 3 of the reactor core, and the end of the vertical connecting part 12 with the elliptical hole 14 is installed on the upper iron yoke 2 of the reactor core, and the discus 4 of the reactor core is located between the upper iron yoke 2 and the lower iron yoke 3.

[0024] In a specific embodiment, the horizontal connecting portion 11 is bolted to the outer side surface of the lower iron yoke 3 through a circular hole 13, and the vertical connecting portion 12 is bolted to the outer side surface of the upper iron yoke 2 through an elliptical hole 14. The diameter of the elliptical hole 14 in the vertical direction is larger than the diameter in the horizontal direction, which is convenient for installation and manual adjustment of inductance. By adding or removing an iron sheet on the iron core of the reactor, the magnetic circuit length can be changed, thereby changing the inductance value.

[0025] The lower iron yoke is made of lower iron yoke pieces stacked layer by layer. The thickness of the lower iron yoke pieces is first calibrated and fixed with pull plates. The improved pull plates are made into an integral pull plate. Each pull plate can maintain a verticality of 90 degrees, which can ensure that the discus does not move during the stacking process. The verticality is guaranteed and the iron core fastening strength is greatly enhanced.

[0026] It comprises an upper iron yoke and a lower iron yoke, with at least one group of winding units arranged between the upper iron yoke and the lower iron yoke, each group of winding units comprises a core column, a pull plate and a hollow winding, the core column is arranged in the hollow part of the winding and is located between the upper iron yoke and the lower iron yoke, each group of unit windings has two pull plates which are arranged on both sides of the core column respectively, the upper iron yoke and the lower iron yoke are arranged between the two ends of the two pull plates respectively, through holes are correspondingly arranged at the two ends of the two pull plates, the upper iron yoke and the lower iron yoke, through bolts are arranged in the through holes and nuts are used to connect the pull plates with the upper iron yoke and the lower iron yoke; yarn tapes are wound around the outside of the two pull plates, and the windings are directly wound around the outside of the yarn tapes.

[0027] First, clamp the core column between two pull plates, wind the yarn tape outside the pull plate, and then perform varnish treatment. After curing, the pull plate, core column and yarn tape are fixed as a whole, with good connection strength; then wind the winding outside the yarn tape, install the upper iron yoke and the lower iron yoke after winding, and then perform varnish treatment again. From the above process, it can be seen that the structure of the present invention can make the winding and the core column have the smallest gap, reduce the leakage magnetic field, and reduce the loss of the reactor; at the same time, due to the omission of the winding bracket, the cost is reduced; the structure can improve production efficiency and assembly accuracy; the present invention can be used in low-frequency circuits to suppress current changes or shift the phase of alternating current.
