Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a power storage mechanism for a load tap selector, and particularly to a simple power storage device with improved driving capability.

[Conventional technology]

An example of a conventional energy storage device for a load tap selector is S.
As shown in the figure.

In the figure, symbol (1) is an input piece for rotating and storing energy, (2) is an output piece that is provided concentrically with the input piece (1) and rotates, and (3) is a rotating output piece (2). The output shaft is connected to the shaft center Klri and transmits power to the load opening/closing movable contact part C (not shown); This is a storage spring which is rotatably connected to the output piece (2) at its inner diameter side end by an inner diameter side spring end member (6) and is disposed in a radial direction from the center.

Next, the operation of this conventional energy storage device will be explained.

When the input piece (1) operates to store energy.

The output piece (2) is controlled by a drive angle control section (not shown).

It is restrained at a first predetermined position in the rotational direction. Next, as shown in FIG. 9, the input piece (1) is rotated by a required angle θ, so that the energy storage spring (example generates deflection and stores energy; FIG. This shows the state just before the released energy is released.

Here, this stored energy E is defined as the radius R from the center to the rotation center of the outer spring end member (,ltl),
It is determined from the radius r to the center of rotation of the inner spring end member (6) and the required angle θ at which the input piece (/I) is rotated.

Now, to simplify the relationship, let θ = 3g as a general example of the required rotation angle of the load tap selector, and let R = γ as an example of the relationship between R and r. The energy E generated is.

E=xO,0! r7r' = 0.0. 2 de kγ1
・・・ ・・・ (
1).

However, to: spring constant becomes.

Next, by the action of the drive angle control section, the above energy E
is released, the movable contact part is rotated at high speed by the output shaft (3) K, and the output piece (2) follows the input piece (1), thereby moving the output piece (2) to a second predetermined position. Stop and restrain. The state at that time is shown in Fig. 1θ.

The above explanation is about the movement from the first predetermined position to the second predetermined position, but it can be easily understood from the symmetry of the configuration that the movement can be performed in the opposite direction as well. O [Problems to be Solved by the Invention] The conventional energy storage device of the load tap selector is configured and operates as described above, and as predicted from the above formula (/1), Geometrically, the typical required angle of the load tap selector does not allow for a large energy storage deflection, and therefore, to obtain the required energy, the outer and inner spring ends must be The problem is that it is necessary to move the member (&1 (A) away from the center or to further increase the number of energy storage springs (4'l) installed, resulting in an increase in size or a complicated configuration. There was a point.

The present invention was made in order to solve the problems of the above-mentioned conventional energy storage devices for load tap selectors. The purpose is to obtain an energy storage device.

[Means for solving problems]

In the energy storage device for a load tap selector according to the present invention, the rod member of the spring end device that locks both ends of the energy storage spring can be detached outwardly in the rotational direction of the input piece and the output piece. The center of the engaging cylindrical part that is engaged with the output piece and also engaged with the input piece and the output piece of the above-mentioned bar members is equidistant from the rotation center of the input piece and the output piece. It is composed of

[For production]

Since the energy storage device of this invention is configured as described above,
The output piece restrains the rod member of one spring end device in one, e.g., first position, and the rod member of the other spring end device is separated from said rod member of said one spring end device and in a second position. The input piece rotates toward the position and is biased into the second position, so that the energy storage spring deflects in the circumferential direction, resulting in a large deflection amount for the same rotation angle.

In other words, a large amount of stored energy can be effectively obtained.
