Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a winding mounting method for mounting a winding on a wound core formed of an amorphous magnetic alloy ribbon, and a winding mounting method used to carry out this method. The present invention relates to a jig for installing winding wire.

[Prior Art] Recently, it has been considered to manufacture iron cores for power distribution transformers using amorphous magnetic alloy ribbons.

Amorphous magnetic alloy ribbons (hereinafter sometimes simply referred to as ribbons) are extremely thin and difficult to handle, so when using them to construct the core of a transformer, A method of forming a unit laminate by combining a plurality of thin ribbons (±several to several dozen) and forming a wound core using a plurality of the unit laminates has been studied.

In the above method, a laminate block formed by laminating a plurality of unit laminates is rolled up, both ends of each unit laminate are shifted in a step-like manner, overlapped and bonded, and a plurality of these laminate blocks are further laminated. This constitutes an iron core with a predetermined thickness.

The core, which is laminated to a predetermined thickness, is shaped into a rectangular shape by positioning the overlapping joint in one yoke, and then the magnetic properties that have deteriorated due to the strain applied during the core manufacturing process are restored. Magnetic field annealing is performed to achieve this.

After manufacturing the wound core in this manner, the winding wire is attached to the legs. When using a wound core made of silicon steel strip, the wound core formed into a rectangular shape is divided into each laminate block, each laminate block is inserted into the window of the winding, and both ends are overlapped. The windings were attached to the core by joining them together, but with a wound core made of amorphous magnetic alloy ribbon, each laminate block was weak and it was impossible to handle each laminate block individually. Have difficulty. In addition, if a method is adopted in which the wound core made of amorphous magnetic alloy thin strips is disassembled into laminated blocks and inserted into the winding window, misalignment occurs between the thin strips that make up each laminated block. Therefore, it is difficult to restore the joint to its original shape, and deformation distortion occurs at the rejoint part, which increases iron loss. I can't do anything anymore. Further, since the amorphous magnetic alloy ribbon after magnetic field annealing is very brittle and easily breaks, there is a risk that fragments of the ribbon may be generated during the process of attaching the winding. If a transformer is assembled with ribbon fragments still attached to the windings, the ribbon fragments will float in the insulating oil filled in the transformer case, causing the transformer to become insulated. will be threatened.

Therefore, when using a wound core made of amorphous magnetic alloy ribbon, after magnetic field annealing, three straight parts (the joints are removed) excluding the yoke where the joints of the rectangular wound core are provided. Cover the yoke (without the yoke and the left and right legs) with insulators to prevent core fragments from leaking, then open the yoke with the joint on both sides at the joint, and then A method is used to attach the winding to the leg of the iron core by inserting the joining end of the iron part into the window of the winding.

[Problem to be solved by the invention] When attaching a winding to a wound core made of an amorphous magnetic alloy ribbon, the work is carried out with the wound core and the winding placed on a workbench. . However, when working with the wound core and windings placed on a horizontal workbench, when the joint is opened, the weak ribbons fall over, causing the joint to lose its shape and become separated. Because the yoke bulges out near the corners, when you try to insert the joint end of the separated yoke into the window of the winding, the ribbon gets caught on the inner surface of the window of the winding, or breaks. The wire installation work could not be carried out smoothly.

In this case, if the cross-sectional area of the window of the coil is made large, the joint end of the iron core can be inserted into the window of the winding relatively easily, but if the window of the winding is made large, the conductor of the winding The amount increases and is uneconomical.

An object of the present invention is to provide a method for attaching a winding to a wound core, which allows the work of attaching the winding to the wound core to be easily carried out, and a jig for attaching the winding used to carry out this method. be.

In the method of the present invention, the work can also be carried out with the winding mounting jig facing the opposite side. In this case, the two windings are arranged side by side, the two sliding plates of the winding mounting jig are inserted into the windows of both windings, and the two sliding plates are placed on the other end of both sliding plates.

Therefore, in this state, if you move the winding installation jig and the wound core relative to the winding and insert both legs of the wound core into the window of the winding, the legs of the wound core will be inserted into the window of the winding. The work of inserting the winding wire into the window can be easily performed.

The process after placing the core on the sliding plate is different in that the moving direction of the jig 4 is different when inserting the leg of the core into the window of the winding, and the direction of movement of the jig 4 is different when inserting the leg of the core into the window of the winding. This is the same as in the previous embodiment except that when the jig 4 is pulled out after being inserted into the window of the embodiment, the jig 4 is moved in the opposite direction to that when inserting the core leg.

The method shown in FIG. 9 is based on the method shown in FIG.
This can be done by reversing the direction of 180 degrees.

When the winding mounting jig 4 is arranged as shown in FIG. 9, the order of the steps can be changed as appropriate.

For example, one yoke part 1a of the rectangular wound core 1 is connected to the sliding plate 40.
1. With the other end of the core 402 facing toward the other end, and with the pair of joint holding plates 404 and 405 inserted into the window of the rectangular core, slide the legs of the core between the two legs. After performing the step of placing the pair of joint holding plates on the plate to face the opposing inner surfaces of the pair of legs of the wound core, the sliding plate 4 is placed on the plate.
The process of arranging the winding 10.11 on the other end side of the 01° 402 and the process of opening the joint of the wound core can also be performed sequentially.

In addition, a pair of legs of the rectangular wound core 1 are placed on two sliding plates, and a pair of joint core holding plates 404 and 405 are placed between the legs 1c and ld of the wound core. After performing the step of facing the inner surface and the step of opening the joint of the winding core, the step of arranging the winding 10.11 on the other end side of the sliding plate is performed, and then the joint end of the winding core is opened at the joint. The step of locating the holding plate on the outside and the step of moving the sliding plates 401, 402 together with the wound core and inserting the legs of the wound core into the windows of the windings 10.11 may be performed sequentially.

Furthermore, after performing the step of positioning each joint end of the wound core on the outside of the joint holding plate, the winding 10. li
The steps of disposing the sliding plates 401 and 402 together with the wound core and inserting the legs of the wound core into the windows of the windings 10 and 11 may be performed sequentially.

If the winding is arranged after the winding core is attached to the winding installation jig, it is difficult to lift the winding installation jig together with the winding core, so the sliding plates 401, 4
Lower the work table at the other end of 02 so that it does not interfere with the windings, and in this state, arrange the windings 10 and 11 from the side on the winding fixing base 7. It is better to make it .

In the above embodiment, the work tables 5 and 6 are kept horizontal during all processes, but the work tables 5 and 6 and the winding fixing table 7 can be tilted as appropriate with respect to the horizontal plane. The present invention may be configured so that in a particular process, the work is performed with the work table and the winding fixing stand tilted.

For example, in the process of inserting the legs 1c and ld of the wound core into the windows 10a and lla of the windings 10 and 11, the windings 10 and 11 sides are The work tables 5, 6 and the fixed winding bundle 7 may be tilted so that they are lower than the iron core side.

[Effects of the Invention] As described above, according to the present invention, by locating the joint ends on both sides of the open yoke portion of the wound core on the outside of a pair of joint holding plates, each joint end It prevents the wire from falling inward and holds each joint end in a position where it does not interfere with the inner surface of the winding.
In this state, both legs of the winding core were inserted into the window of the winding by moving the winding installation jig and the winding core relative to the winding. There is an advantage that the work of inserting the wire into the window of the winding can be easily performed.

In addition, in the present invention, since a winding mounting jig having a structure in which two sliding plates are connected at one end is used, the two sliding plates can be treated as a single unit and both sliding plates can be moved at the same time. Therefore, there is an advantage that workability can be improved and the winding installation work can be carried out smoothly.

In particular, in the invention described in claim 3, with the guide strip inserted between both joint ends of the winding core and the joint holding plate, the winding core is moved relative to the jig together with the guide strip. By doing this, the joint end of the wound core is positioned outside the joint presser plate, so it is possible to prevent the joint end of the winding core from being damaged.

According to the invention described in claim 4, a belt is attached to the outer peripheral surface of the wound core, and both ends of the belt are inserted into the windows of the two windings, and then the joint ends of the wound core are connected. Since the step of inserting into the window of the winding is performed, the work of inserting both legs of the wound core into the window of the winding can be performed more smoothly.
