関するものである。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.
従来の負荷タツプ選択器の蓄勢装置の一例を示

An example of a conventional energy storage device for a load tap selector is shown in FIG.
図において符号１は回転して蓄勢するための入

射方向に配設された蓄勢ばねである。 In the figure, numeral 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 movable load switching contact that is fastened to the axis of the rotating output piece 2. An output shaft 4, which transmits a driving force to a part (not shown), has an outer end rotatably connected to the input piece 1 by an outer spring end member 5, and an inner end. is a storage spring that is rotatably connected to the output piece 2 by an inner diameter spring end member 6 and is arranged in a radial direction from the center.
次にこの従来の蓄勢装置の動作について説明す

入力片１が蓄勢のための動作をするに際して、
出力片２は駆動角度制御部（図示せず）によつ

はたわみを発生してエネルギーを蓄えるが、第９
図はこの備えられたエネルギーが放蓄される直前
の状態を示す。 When the input piece 1 operates to store energy,
The output piece 2 is restrained at a first predetermined position in the rotational direction by a drive angle control section (not shown).
Next, as shown in FIG.
It generates deflection and stores energy, but the 9th
The figure shows the state just before this stored energy is released and stored.
ここで、この蓄えられるエネルギーＥは、中心
からの外径側ばね端部材５の回転中心までの半径
Ｒと、内径側ばね部材６の回転中心までの半径ｒ
と、入力片１が回転した所要の角度θとから決定
される。 Here, this stored energy E is calculated by the radius R from the center to the rotation center of the outer spring end member 5 and the radius r from the center to the rotation center of the inner spring member 6.
and the required angle θ of rotation of the input piece 1.
いま、その関係を簡単のために負荷タツプ選択

ただし、ｋ：バネ定数
となる。 Now, to simplify the relationship, we will use θ as an example of a general angle of the required rotation angle of the load tap selector.
= 30°, and as an example of the relationship between R and r, R
= 2r, the stored energy E is: E=k/2×0.057r 2 =0.029kr 2 ...(1) where k: spring constant.

と第１０図に示す状態である。 Next, the energy E is released by the action of the drive angle control section, and the movable contact section is rotated at high speed by the output shaft 3, causing the output piece 2 to follow the input piece 1, thereby producing an output. The piece 2 is stopped and restrained at a second predetermined position. The state at that time is shown in FIG. 10.

Since the energy storage device of the conventional load tap selector is constructed and operates as described above, it can be predicted from the above equation (1) that the general required angle of the load tap selector is In this case, a large deflection of the energy storage spring 4 cannot be obtained, and therefore, in order to obtain the required energy, the outer diameter side and inner diameter side spring end members 5, 6 must be
It is necessary to move the spring away from the center or to further increase the number of energy storage springs 4 installed, resulting in a problem of an increase in size or a complicated configuration.

Since the energy storage device of the present invention is constructed as described above, the output piece restrains the carrier member of one spring end device in the first position, and the carrier member of the other spring end device is restrained in the first position. The member is moved into the second position by the input piece, which moves away from the carrier member of said one spring end device and rotates towards the second position, so that the energy storage spring is moved in the circumferential direction. As a result, a large amount of deflection, that is, a large amount of stored energy can be effectively obtained for the same rotation angle.

又は第４項記載の負荷タツプ選択器の蓄勢装置。[Scope of Claims] 1. An output piece that rotates at high speed using a load switching movable contact portion as a load, an input piece that is provided concentrically with the rotation center of the output piece and rotates, and stores energy through the rotation of the input piece, an energy storage spring that applies the energy to the contact portion, and when the input piece is rotated with the output piece restrained in the first position and the energy is stored in the energy storage spring, the output The output piece is rotated to follow the input piece by releasing the restraint of the piece, and the input piece and the output piece are turned into a second piece.
In the energy storage device for a load tap selector having a drive angle control unit configured to reversibly stop and restrain the spring in a certain position, a spring end device that locks both ends of the energy storage spring, respectively. The supporting member is
A load tap selection characterized in that the load tap is engaged with the input piece and the output piece at a position equidistant from the rotation center of the output piece so as to be detachable outward in the rotational direction of the input piece and the output piece. Energy storage device for vessels. 2. The output piece and the input piece each have two plate-shaped protrusions each having a plane perpendicular to the rotation center, with one of the output piece and the input piece facing in the outer radial direction, and the other facing in the inner radial direction. Each of the two plate-like protrusions has a space between the two plate-like protrusions on either one of the output piece and the input piece. The other two plate-shaped protrusions have a space between them that can accommodate the energy storage spring, and the two plate-shaped protrusions are arranged side by side so as to overlap each other. Cuts are formed on both sides in the rotational direction, with which the supporting member of the spring end device engages and is removable toward the outside in the rotational direction, and the spacing between the cuts on both sides of each plate-like projection is 2. The energy storage device for a load tap selector according to claim 1, wherein the plate-shaped protrusions of adjacent output pieces and input pieces are formed at equal intervals and at equal distances from the center of rotation. 3. The spring end device consists of a support member and a latch, the support member having an eccentric cylindrical part in the center thereof, an inner collar part on both sides of the eccentric cylinder part, and an eccentric part on each end side of the inner collar part. An engaging portion that is eccentric to the cylindrical portion and capable of engaging with notches in two adjacent plate-like projections is provided with an outer collar on the end side of the engaging portion, and the latch is The energy storage of the load tap selector according to claim 2, wherein one end is locked to the end of the energy storage spring, and the other end is formed with a hole that rotatably fits into the eccentric cylindrical portion. Device. 4 The radius of the outer flange portion and the inner flange portion is formed larger than the radius of the notch of the plate-shaped projection that engages with the engaging portion between the outer flange portion and the inner flange portion, and at least 4. The energy storage device for a load tap selector according to claim 3, wherein a part of the outer diameter surface is formed to be retracted more than the outer diameter surfaces of the inner rib portions on both sides. 5 The two engaging parts formed on the same support member are formed concentrically, the diameter of the eccentric cylindrical part is larger than the diameter of the engaging part, and the hole of the latch is in contact with the eccentric cylindrical part. An energy storage device for a load tap selector according to claim 3 or 4, wherein the contact surface is formed as an arcuate surface having the same radius as the radius of the eccentric cylindrical portion.
