Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a tap position display device for displaying the highest and lowest tap positions incorporated in a tap changer driving device.

[Conventional technology]

The conventional tap position display device of this type is constructed as shown in FIGS. 3 and 4.

That is, in the drawing, 11 is an input gear, 12 is a bearing gear meshed with the input gear, 13 is a pointer indicating the highest tap position attached to the bearing gear 12, and 14 is a lowest tap position attached to the bearing gear 12. Pointer, 15 is a tap position name plate attached to the bearing gear 12, 16 is a pointer that moves with the rotation of the bearing gear 12.
It is a stopper that stops the movement of 13 and 14.

In this conventional type, the driving force is transmitted to the bearing gear 12 via the input gear 11, and the bearing gear 12 is rotated by an angle of one tap. For example, if it is moved from the tap position 6 in FIG. 3 to the tap position 9, the bearing gear 12 rotates clockwise by an angle of 3 taps, and the pointer 14 indicating the lowest tap position attached to the bearing gear 12 is Although it rotates together with the bearing gear 12 away from the stopper 16, the pointer 13 indicating the maximum tap position shows
The bearing gear 12
Indicates the highest tap when it reaches tap position 9. Next, when the bearing gear 12 moves counterclockwise, the pointers 13 and 14 move together with the bearing gear 12 up to the tap position 6, but only the pointer 14 indicating the lowest tap position when moving beyond the tap position 6. Is stopped by the stopper 6 and remains stopped, and the bearing gear 12 indicates the lowest tap position at the stopped position.

[Problems to be solved by the device]

In this conventional tap position display device, since the tap position nameplate 15 must be attached to the bearing gear 12 after the tap position alignment with the main body at the time of assembly, the fine adjustment work of the alignment and the tap position nameplate after the assembly are performed. However, the assembly work was complicated and time-consuming.

The present invention has been made in order to solve the problems of the conventional ones, and is intended to allow the tap position name plate to be attached without performing a tap position adjusting operation after assembling.

[Means for Solving the Problems]

The tap position display device according to the present invention has a bracket attached to a rotating drive shaft in conjunction with a tap changer, and the bracket is engaged with the bracket through a contact plate, and the maximum tap position and the minimum tap position. A tap position indicator for displaying each is rotatably arranged, and the tap position indicator is configured to rotate when the clasp and the contact plate are engaged.

[Action]

Since the clasp in this invention is attached to the drive shaft, the adjustment is easy, and since the tap position nameplate can be attached to the tap position indicator in advance, the tap position can be easily adjusted after assembly.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. That is, in FIGS. 1 and 2, 21 is a drive shaft which is rotated in conjunction with a tap changer (not shown),
22 and 23 are hooks for moving the highest side tap position indicator 24 and the lowest side tap position indicator 25 slidably mounted on the fixed part, and 26 and 27 are attached to the tap position indicators 24 and 25. The tap position name plates, 28 and 29, are metal plates attached to the tap position indicators 24 and 25.

With such a configuration, when the drive shaft 21 rotates, the bars 22 and 23 fixed to the drive shaft 21 also rotate in the same direction,
For example, in the counterclockwise direction, the highest tap side bracket 22 pushes the contact plate 28 attached to the highest tap position indicator 24 and moves it to the highest tap. On the other hand, when rotating in the clockwise direction, the lowest tap side bracket 23 pushes the contact plate 29 attached to the lowest tap position indicator 25 and moves it to the lowest tap. In this way, the highest tap position and the lowest tap position in the range where the tap changer operates are displayed.

In this tap position display device, the highest side tap position indicator
24, the tap position nameplates 26 and 27 can be attached to the tap position indicator 25 on the lowest side in advance, and can be assembled regardless of the tap position with the main body. Bring it to the tap position and fix the brackets 28 and 29 accordingly.

[Effect of device]

As described above, in the tap position display device according to the present invention, since the tap position nameplate can be attached to the tap position indicator before assembly, not only is it unnecessary to attach the nameplate after the tap position adjustment after assembly, Adjustment work for tap position adjustment becomes easy and work time can be shortened.
