Title:
ACCUMULATOR HAVING MULTIPLE MECHANICAL ENERGY STORAGE DEVICES FOR USE IN ON-LOAD TAP-CHANGER AND ON-LOAD TAP-CHANGER
Document Type and Number:
WIPO Patent Application WO/2022/179280
Kind Code:
A1
Abstract:
The present invention relates to an accumulator having multiple mechanical energy storage devices for use in an on-load tap changer, and an on-load tap changer. A driving shaft in the accumulator can rotate in any direction under the drive of a motor mechanism; a drive transmission mechanism having a variable instantaneous transmission ratio switches the rotation of the driving shaft in any direction into unidirectional rotation, and causes the driving shaft to rotate in an opposite direction in the next switching of the on-load tap-changer, so as to drive a driving device to rotate; the tension or relaxation states of different mechanical energy storage devices is achieved by means of the rotation of the driving device; and after the mechanical energy storage devices are in place, a driven device is driven to rotate, thereby achieving a desired rotation angle of a driven shaft. The present invention prevents cumbersome motion transformation between rotary motion and linear motion of the accumulator, such that the motion transmission efficiency and reliability of the accumulator are higher. In addition, the present invention prevents the friction between an eccentric wheel and an upper carriage, thereby reducing the possibility of producing wear debris and achieving the advantages of low wear and high reliability.
