Title: Junping Lyu and His Patent for an On-Load Tap Changer Accumulator

Introduction

Junping Lyu is an inventor based in Beijing, China. His work includes a patent for a full-range boosting device designed for an accumulator used in an on-load tap changer.

Latest Patents

Lyu is associated with 1 patent: “Full Range Boosting Device for Accumulator of On-Load Tap Changer, Accumulator, and On-Load Tap Changer.” The invention uses two sheave intermittent mechanisms arranged alternately in an up-and-down direction, together with a central gear that drives both mechanisms. Each mechanism includes a dial gear, a coaxially fixed driving dial, a dial round pin, a driven sheave with a radial slot, and a boosting plate connected to the sheave.

As one driving dial rotates through an angle of α1, the dial pin and radial slot work together to turn its boosting plate through the intended boosting angle. Meanwhile, the other mechanism rotates through 360°−α1, positioning its dial pin at the radial slot’s notch. This coordinated arrangement supports the accumulator’s boosting operation.
