Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a mounting device for a disconnector, particularly for a phase-separating busbar used for a main circuit of a generator.

[0002]

2. Description of the Related Art FIG. 7 is a sectional view of a disconnector for a phase separation busbar. In the figure, the supporting insulators 25 and 26 for supporting the conductor 2B housed in the jacket 1 are composed of an insulating member 5A and a flange 5B integrally connected thereto. The lower end of the lower support insulator 25 is attached to the support base 9 welded to the jacket 1 by fixing the flange 5B with bolts 10. The upper end of the lower support insulator 25 and the lower end of the upper support insulator 26 are attached by bolts 12 to respective support seats 11 welded to the conductor 2B. The flange 5B at the upper end of the upper support insulator 26 is attached to the holding metal fitting 15 with the bolt 16, and the holding metal fitting 15 has the plate-shaped mounting seat 13 welded to the jacket 1 and the spacer 14 for assembly and adjustment. It is attached by a bolt 15A. The mounting portion is covered with a protective cover 17.

Next, the attachment adjustment of the support insulator 26 will be described with reference to FIG. The jacket 1 and the conductor 2B are generally manufactured by forming an aluminum plate into a cylindrical shape in consideration of energization performance and heat radiation. However, due to welding distortion in the sheet metal working process such as welding, it is usually several mm to 10 mm.
A dimensional error of about mm occurs. In the assembling work for supporting the conductor 2B inside the jacket 1, first, the lower support insulator 25 and the conductor 2B are assembled, and then the upper support insulator 26 is assembled. At this time, due to the above dimensional error,
A gap is created between the upper surface of the mounting seat 13 and the mounting portion of the holding fitting 15. So in this gap 0.5mm, 1mm, 3m
Spacer 14 that combines metal plates of several thicknesses such as m
Insert A and 14B so that the gap is almost filled.
That is, the spacers 14A and 14B are inserted to fill this gap where the manufacturing errors of the respective parts are finally accumulated, and in FIG. 7, not only the error in the vertical direction but also the inclination of the conductor 2B in the horizontal direction. Is adjusted by slightly changing the plate thickness of the left and right spacers 14A and 14B inserted on the upper surface of the mounting seat 13.

[0004]

Since the conventional disconnector is constructed as described above, it is uneconomical to prepare a large number of metal plates of various thicknesses as spacers for adjustment. . Further, since it is necessary to select an optimum combination from spacers having different plate thicknesses, there is a problem that the adjustment work requires a lot of time due to trial and error.

In order to solve the above problems, it is an object of the present invention to provide a mounting device which does not use a spacer for assembly and adjustment.

DISCLOSURE OF THE INVENTION A mounting device for a disconnector for a phase-separated bus of the present invention is a male screw screwed into the screw hole of a mounting seat plate having at least one screw hole on the outer surface thereof. And an adjusting screw having a through hole along the central axis is inserted, a flange facing the mounting seat plate and having a mounting hole at a position corresponding to the screw hole of the mounting seat plate is It is coupled to the mounting seat plate by a bolt penetrating the through hole and the mounting hole.

[0006]

By adjusting the protruding length of the adjusting screw inserted into the screw hole of the mounting seat plate, the dimensional error in the mounting portion of the supporting insulator is compensated.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to FIGS.
It will be described based on. FIG. 1 is a sectional view of a disconnector for a phase separation busbar having a mounting device according to an embodiment of the present invention, and FIG. 2 is a partial sectional view taken along arrow BB in FIG. Further, FIG. 3 is a detailed sectional view of a C portion in FIG. In FIG. 1, the supporting structure by the supporting insulator 25 below the conductor 2B is the same as that shown in FIG. A plate-shaped mounting seat plate 18 is fixed to the upper portion of the cylindrical outer cover 1. A plan view of the mounting seat plate 18 is shown in FIG. In the figure, the mounting seat plate 18
Has four screw holes 18A, and each screw hole 18A is screwed with an adjusting screw 19 having a male screw 19D on the outer surface and a through hole 19C along the central axis as shown in FIG. There is. The head 19A of the adjusting screw 19 is hexagonal or quadrangular so that it can be turned with a spanner. Mounting seat plate 18
The flange 5B of the support insulator 26 that supports the upper portion of the conductor 2B is arranged facing the. The flange 5B is provided with a mounting hole 5C at a position corresponding to the screw hole 18A of the mounting seat plate. This mounting hole 5C and the through hole 1 for the adjusting screw 19
The fixing bolt 20 penetrates through 9C, and the washer 21
And adjusting nut 19 and supporting insulator 26 using nut 22
Is connected to the flange 5B at the lower end 19B of the adjusting screw 19. The support seat 11 below the support insulator 26 and the conductor 2B
Means that the support seat 11 is connected to the conductor 2B using the bolt 12. Next, the adjustment of the mounting device will be described with reference to FIG. Since the length of the thread portion of the adjusting screw 19 is sufficiently longer than the plate thickness of the mounting seat plate 18, the lower end 19B thereof protrudes from the lower surface of the mounting seat plate 18. The protruding length G is larger than the dimensional error of the jacket 1 and the conductor 2B. That is, in the configuration of FIG. 1, the cumulative error in the dimensions of the conductor 2B and the outer cover 1 is caused by the mounting seat plate 18 and the flange 5.
The length G is set to be sufficiently large such that the length G between B is equal to or less than the length G. In the adjustment, the adjusting screw 19 is turned without tightening the fixing bolt 20, and the tip end 19B of the adjusting screw 19 is brought into contact with the flange 5B. Next, the flange 5B and the adjusting screw 19 are tightened and fixed by the fixing bolt 20 and the nut 22. The inner diameter of the hole 19C of the adjusting screw 19 is made sufficiently larger (for example, several millimeters) than the outer diameter of the threaded portion of the fixing bolt 20, and the flange 5B is attached to the mounting seat plate 18 in the left-right direction in FIG. Alternatively, it can be adjusted even when it is displaced in the front-back direction. If the mounting seat plate 18 and the flange 5B are not parallel and tilted, the four adjustment screws 1
Adjustment is performed by changing the protruding lengths G of 9 respectively.

In the above embodiment, two supporting insulators 25 and 2 are used.
Although 6 is provided above and below the conductor 2B, the conductor 2B may be supported in three directions by using three supporting insulators 25, 26 and 27 as shown in the embodiment of FIG. In this case, two support insulators 2 out of the three support insulators 25, 26, 27
6, 27 may be attached using the attachment device of this embodiment. Further, even when four or more supporting insulators 25 are used, the mounting device of this embodiment can be used.

Further, in the above-mentioned embodiment, the flange 19A of the adjusting screw 19 is formed in a hexagonal shape, but as shown in the embodiment of FIG. You may provide the two planar parts 23A and 23B. With this configuration, the outer diameter of the adjusting screw 29 is reduced, and the space occupied by the adjusting screw 29 can be reduced. The application of the mounting device of the present invention is not limited to only the phase-separation busbar disconnector, but can be applied to other devices that require fine adjustment of the positional relationship between two components. For example, in FIG.
Shows an embodiment in which the mounting device of the present invention is provided on the mounting plate 28 of the motor 31. In this example, the position of the flange 30 to which the motor 31 is fixed is adjusted by rotating the adjusting screw 19, and for example, the speed reducer 3 fixed to the mounting plate 28 is adjusted.
The shaft 32 of the motor 31 can be correctly positioned on the mounting shaft 33 of No. 4.

[0010]

According to the present invention, the gap due to the dimensional error between the mounting seat plate 18 and the flange 5B of the support insulator 26 is held by the protruding portion of the adjusting screw 19 inserted into the screw hole of the mounting seat plate 18. Adjust the position. Since the length G of the protruding portion can be arbitrarily changed by turning the adjusting screw 19, it can be adjusted quickly and easily.
