The present invention relates to a slider for assembling a core of a stationary induction device on which an iron core piece is mounted.

[Conventional technology]

FIG. 3 shows a shell-type transformer which is a general stationary induction device.

In the figure, a lower tank flange (2) is provided around the upper surface of the lower tank (1). Lower tank (1)
Inside, a coil (3) having a coil window (4) is disposed so as to protrude above the lower tank (1). A beam (5) is arranged below the coil window (4), supported by the upper surface of the lower tank flange (2). The lower spacer (6) is disposed between the lower surface of the outer periphery of the outer leg iron cores (7b, 7c) and the lower tank flange (2).

A wedge (8) is inserted at the upper end of the coil window (4).

An iron core holder (11) is arranged on the outer peripheral upper surface of the outer leg iron cores (7b, 7c) via an upper spacer (9).

An upper tank flange (12) welded to the lower tank flange (2) is provided around the lower surface of the upper tank (10).

Next, a brief description will be given of a conventional assembling procedure of the shell-type transformer configured as described above.

 First, the coil (3) is set up in the lower tank (1).

Next, the beam (5) is disposed at the lower portion in the coil window (4) so that both ends in the longitudinal direction of the beam (5) ride on the lower flange (2), and the outer lower tank flange (2) of the coil (3) is formed. A lower spacer (6) is arranged on the upper side.

Next, as shown in FIG. 4, the iron cores (7a, 7b, 7c) are laminated one by one on the beam (5) and the lower spacer (6), and then the iron cores (7b, 7b) on the outer periphery of the coil (3) are stacked. 7c) An upper spacer (9) is arranged on the upper side, and a wedge (8) is driven into the coil window (4) between the iron core (7a) and the coil (3).

[Problems to be solved by the invention]

As described above, in the conventional static induction device, since the core cores are laminated one by one, a long working time is required to obtain a core having a predetermined stacking height. In order to stack the layers one by one, the iron core plate tends to be displaced, and the core must be positioned each time the layers are stacked, which causes a problem that the working time is further increased.

In contrast, the applicant has, according to an earlier patent application,
After the cores of the center leg and the outer leg are shifted in advance by the overlap margin of the core base material and laminated and fixed on the slider to form a block-shaped core piece, and the core piece mounted on the slider is moved to a predetermined position. Filed an invention in which the iron core was assembled by pulling out the slider and placing the iron core piece in place.

However, in this technique, the iron core pieces configured in a block shape are stacked so that they overlap each other in the vicinity of the iron core plate. Therefore, the lowermost iron core plate is assembled in assembling. There is a problem that an iron core plate must be laminated on the slider in consideration of the position, and the prior invention which has a problem to solve this problem has.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and the assembling of the iron core can be performed in a short time by the above-mentioned prior invention. It is an object of the present invention to obtain a slider for assembling a core of a stationary induction device, which can stack an iron core plate on a core without considering its position.

[Means for solving the problem]

In the slider for assembling a stationary induction device iron core according to the present invention, in order to insert the block-shaped iron core piece into the stationary position from either the front or rear direction, tension connecting metal fittings are provided at both ends of the slider. It is constructed so that it can be attached and detached, and is provided with a slope for sliding down the block-shaped core piece at both ends.

(Operation)

Since the slider for assembling the core of the stationary induction device according to the present invention is configured as described above, in order to insert the block-shaped core piece into the predetermined position of the transformer coil, it is necessary to pull the slider to the required end of any slider. Attach the connection metal fittings, index the slider with this tension connection metal fitting in the desired direction, and slide down the core piece on the slope at the end of the slider when pulling down the block-shaped iron piece from the slider. And pull out the slider.
The block-shaped core piece can be fixed without deforming.
