Description

Technical Field

[0001] The utility model relates to the technical field of reactors, in particular to a dry-type reactor forming and curing device. Background Art

[0002] The dry-type reactor coil is tightened and fixed by epoxy wire drawing between the busbar and the winding, so that the winding and the busbar are spliced ​​and fixed as a whole. The busbar is generally divided into two groups, upper and lower, and multiple groups of busbars are staggered to form a whole. Each busbar arm of the upper and lower busbars corresponds to each other. Since the dry-type reactor coil adopts the wet winding process, the coil needs to be put into the furnace for drying and curing after winding. During the curing process, the coil end encapsulation will gradually change from wet to dry.

[0003] After searching, the Chinese patent application number CN219956120U discloses a dry-type inductor forming and curing device, including a plurality of brackets arranged along the circumferential direction of the coil, and adjacent brackets are connected by a first oblique reinforcement plate and a second oblique reinforcement plate arranged crosswise, the bracket includes two bracket side plates arranged at an angle, a first connecting plate is provided at both ends of the first oblique reinforcement plate, a second connecting plate is provided at both ends of the second oblique reinforcement plate, and the first connecting plate and the second connecting plate are respectively fixed to the corresponding bracket side plates, and in addition, a slot is provided in the middle of the second oblique reinforcement plate for the corresponding first oblique reinforcement plate to pass through, the upper end of the bracket is connected to the corresponding upper bus arm of the upper bus on the upper side of the coil, and the lower end of the bracket is connected to the corresponding lower bus arm of the lower bus on the lower side of the coil.

[0004] However, in actual use, it was found that although the first connecting plate and the second connecting plate can limit the outside of the coil, the internal coil is wound. During the drying process, since the two ends of the coil are not constrained, it is inevitable that deformation will occur during the curing process, affecting the curing effect of the coil.

[0014] 1. The dry-type reactor forming and curing device can effectively prevent the coil body from being deformed during the curing process by limiting the two ends of the coil body.

[0023] Example:

[0024] Reference Figure 1-Figure 4 A dry-type reactor forming and curing device comprises a support frame 1 and two groups of symmetrical busbars 101 (the busbars 101 are fixed to form a whole by staggered splicing), a support seat 102 is fixedly connected to the busbar 101 for support, and the two groups of symmetrical busbars 101 are detachably connected to the two ends of the support frame 1, and can be limited by locking bolts or locking screws, a circular notch 2 is also provided on the busbar 101, and a rotatable reciprocating screw 201 is also installed in the circular notch 2, and then the mounting plate 3 is threadedly connected to the reciprocating screw The rod 201 is on the mounting plate 3, and the mounting plate 3 is fitted with the inner wall of the circular slot 2. A torsion plate 202 is fixedly connected to the end of the reciprocating screw 201 away from the mounting plate 3. By rotating the torsion plate 202, the reciprocating screw 201 can be rotated, so that the mounting plate 3 can be lifted and lowered on the reciprocating screw 201. An extension arm 4 is also installed on the mounting plate 3, and an extension plate 6 is also installed on the bus 101. A limiting groove 601 is opened on the extension plate 6, and then the extension arm 4 is fitted with the inner wall of the limiting groove 601, so that the extension arm 4 is limited.

[0025] In addition, refer to Figure 2 A plurality of groups of equally spaced limit blocks 5 are fixedly connected to the extension arm 4, and the number of the limit blocks 5 can be adjusted and installed according to the number of coil windings installed on the dry-type inductor, and the number range can be (5-20 groups). The preferred number in the device can be 11 groups. In addition, a coil body 7 is also arranged between the two groups of bus bars 101, and the coil body 7 in the device is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and the operator is required to adjust the number of the limit blocks 5 according to the actual diameter specification of the coil body 7.

[0026] It needs to be explained that when the coil body 7 set in the dry-type inductor needs to be put into the furnace for drying, the coil body 7 can be placed between two groups of symmetrically arranged bus bars 101, and then the support frame 1 can be limited to the installation position by means of locking bolts or locking screws. At this time, the torsion plate 202 can be rotated to drive the reciprocating screw 201 to rotate, and then the reciprocating screw 201 drives the installation plate 3 to rise and fall in the circular groove 2, and then drives the extension arm 4 to abut against the two sides of the coil body 7, and the two ends of the coil body 7 are located between the two groups of limit blocks 5, and then the two ends of the coil body 7 can be limited and abutted, which can effectively prevent the coil body 7 from being deformed during the curing process. During the curing process, (the encapsulation of the coil end will gradually change from a wet state to a dry state, and this state change may cause deformation of the coil), the deformation of the coil can be reduced by limiting and abutting, ensuring the stability of the geometric shape and structure of the coil, which is beneficial to the stable progress of the curing process and improves the curing effect.
