Description

Technical Field

[0001] This utility model relates to the field of reactor clamp insulation, and in particular to a reactor with a clamp insulation device. Background Technology

[0002] Reactors are generally equipped with a yoke, and clamps are usually installed at both ends of the yoke. The clamps on both sides are usually 30mm lower than the height of the yoke to facilitate the clamps' fixation.

[0003] However, after the clamps are fixed, the height of the clamps is inconsistent with the height of the yoke. Therefore, after the reactor has been running for a long time, the silicon steel sheets in the yoke will not be clamped tightly, resulting in loosening, strong vibration and loud noise, and intermittent discharge, thus causing safety hazards. Utility Model Content

[0004] This utility model overcomes the shortcomings of the prior art where the lower yoke clamp of the reactor is easy to loosen, and provides a reactor with a clamp insulation device. To achieve the above objective, the technical solution adopted by this utility model is: a reactor with a clamp insulation device, which includes: a side yoke, a lower yoke, insulation components disposed on both sides of the lower yoke, and a fixing component disposed on the lower yoke.

[0005] The insulating assembly includes a plurality of pads disposed on the outer side of the lower yoke, an insulating plate disposed on the outer side of the pads, and a clamp disposed on the outer side of the insulating plate;

[0006] At least a portion of the pads are at the same height as the lower yoke, and the insulating plate is at the same height as the clamp.

[0007] In a preferred embodiment of this invention, at least a portion of the pads are taller than the insulating plate.

[0008] In a preferred embodiment of this utility model, the pad with a height less than that of the lower yoke is a first pad, and the height of the first pad is equal to that of the insulating plate.

[0010] In a preferred embodiment of this utility model, a fixed shaft is provided on one side of the lower yoke, and the insulating pull strap is wound around the fixed shaft and fixed to the first pad block.

[0011] In a preferred embodiment of the present invention, the pads are evenly distributed along the stacking direction of the silicon steel sheets of the lower yoke, wherein at least two pads are replaced by the first pad.

[0012] In a preferred embodiment of this utility model, a support rod is provided between the insulating pull strip and the lower yoke.

[0013] In a preferred embodiment of this utility model, the support rod is made of laminated wood, and the cross-section of the support rod is a quarter circle.

[0014] In a preferred embodiment of the present invention, the fixing component includes a through-bolt and a pull rod, wherein the through-bolt is disposed inside the lower yoke along the stacking direction of the silicon steel sheets of the lower yoke;

[0015] The pull screw is arranged parallel to the through screw, and the pull screw is located below the lower yoke.

[0016] In a preferred embodiment of this utility model, a fixing plate is provided on one side of the lower yoke, and the fixing plate is fixedly disposed with the insulating plate.

[0030] A reactor with an insulating device for clamp 204, such as Figure 2 As shown, it includes: a side yoke 101, a lower yoke 102, insulating components disposed on both sides of the lower yoke 102, and fixing components disposed on the lower yoke 102.

[0031] Among them, reference Figure 3 The insulation assembly includes a plurality of pads 201 disposed on the outside of the lower yoke 102, an insulation plate 203 disposed on the outside of the pads 201, and a clamp 204 disposed on the outside of the insulation plate 203.

[0032] At least some of the pads 201 are at the same height as the lower yoke 102, and the insulating plate 203 is at the same height as the clamp 204.

[0033] Among them, the pad 201 is generally made of the same material glued and riveted to a 3mm hot-pressed polyester resin plastic laminate. The pad 201 is about 30mm wide and about 13mm thick. The pad 201 is used to clamp the 30mm high silicon steel sheet.

[0034] Combination Figure 2 and Figure 4 As shown, at least some of the pads 201 have a height greater than the height of the insulating plate 203. The pads 201 with a height less than the height of the lower yoke 102 are the first pads 202, and the height of the first pads 202 is equal to the height of the insulating plate 203.

[0035] That is, the spacers 201 are evenly distributed along the stacking direction of the silicon steel sheets of the lower yoke 102, wherein at least two spacers 201 are replaced by the first spacer 202.

[0036] Combination Figure 3 and Figure 4 As shown, the first pad 202 and the lower yoke 102 are bound and fixed together by an insulating strap 301. A fixing shaft 302 is provided on one side of the lower yoke 102, and the insulating strap 301 is wound around the fixing shaft 302 and fixed to the first pad 202. Here, since at least two insulating straps 301 are provided, the pad 201 at the corresponding insulating strap 301 usually needs to be retracted in length; therefore, the first pad 202 is used to replace the pad 201.

[0037] Combination Figure 2 and Figure 3 As shown, a support rod 303 is provided between the insulating pull strip 301 and the lower yoke 102. The support rod 303 is made of laminated wood and has a quarter-circular cross-section. The laminated wood serves to secure the entire device.

[0038] Continue to refer to Figure 3As shown, the fixing assembly includes a through-bolt 401 and a pull rod 402. The through-bolt 401 is disposed inside the lower yoke 102 along the stacking direction of the silicon steel sheets. The pull rod 402 is disposed parallel to the through-bolt 401 and is located below the lower yoke 102. The through-bolt 401 and pull rod 402 enhance the rigidity and strength of the lower yoke 102, increasing its stability.

[0039] In addition, in one embodiment of the present invention, a fixing plate 501 is provided on one side of the lower yoke 102. The fixing plate 501 is fixedly disposed with the insulating plate 203 by bolts.

[0040] This invention increases the height of the pad 201 to match that of the lower yoke 102, which can better clamp the lower yoke 102 and prevent it from loosening after long-term use. This enhances the rigidity of the entire device and ensures the stability and safety of the reactor during long-term operation.

[0041] This utility model also includes an upper yoke and a clamp, the structure and fixing method of which are symmetrical to the structure of the lower yoke 102 and the clamp.

[0042] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
