Title:
LOAD SWITCH FOR TAP CHANGEOVER DEVICE OF ON-LOAD TAP-CHANGING TRANSFORMER
Document Type and Number:
Japanese Patent JPH0689821
Kind Code:
A
Abstract:
PURPOSE: To obtain the load-break switch having an elasticity storing device for reducing friction very small by avoiding a post-body guide by fixing an element to be moved by openable pawls at first when the driven element completely lifts up a driving element. CONSTITUTION: An elasticity storing device, which can be biased and de-biased in both directions, comprises a driving thin plate 19 and a driven thin-plate 21, which can be moved relatively and mutually. These thin plates 19 and 21 have the same notch 22 in the interior. A compressing spring 28 is supported for the inside of the notch 22. This spring 28 can be tightened by substantially reducing the notch 22 by relative motion. Furthermore, when the driving plate 19 is completely lifted up, pawls 25 and 26 for biasing the thin plate 21 are disengaged. Thus, the thin plate 21 strikingly follows the motion of the driving thin plate 19. Thus, the load-break switch having the elasticity storing device can be simply manufactured, a post-body guide can be avoided and the friction becomes very small.
