Title:
FULL-RANGE ADVANCING DEVICE FOR ON-LOAD TAP CHANGER ACCUMULATOR, ACCUMULATOR, AND ON-LOAD TAP CHANGER
Document Type and Number:
WIPO Patent Application WO/2022/183670
Kind Code:
A1
Abstract:
The present invention relates to a full-range advancing device for an on-load tap changer accumulator, an accumulator, and an on-load tap changer. The full-range advancing device comprises two Geneva intermittent mechanisms and a central gear. The two Geneva intermittent mechanisms each comprises a cam gear, a drive cam, a cam pin, a driven Geneva wheel, and an advancing plate; the drive cam having the cam pin is coaxially fixed to the cam gear without axial contact; the advancing plate is fixedly connected to the driven Geneva wheel; and the driven Geneva wheel is provided with a radical slot. The two Geneva intermittent mechanisms are staggered in the vertical direction; the two cam gears are driven by the same central gear. The positional relationship of the two Geneva intermittent mechanisms satisfies the following constraint conditions: when the drive cam of one of the Geneva intermittent mechanisms rotates by an angle of α1, the cam pin works in conjunction with the radical slot on the driven Geneva wheel to cause the advancing plate on the driven Geneva wheel to rotate by an angle of α for advancing; and when the drive cam of the other Geneva intermittent mechanism rotates by an angle of (360°-α1), the cam pin is just located in the opening of the radical slot.
