MHP型纯机械液压过速保护装置是专为水轮发电机组当调速器和事故配压阀等过速保护装置均发生故障时提供最后一道保护的装置。从其发展过程与现状,介绍一种新型纯机械液压过速保护装置。
MHP pure mechanical hydraulic over-speed protection device is designed for hydro-generator set when the governor and accident pressure relief valve and other over-speed protection devices have failed to provide the last protection device. From its development process and the status quo, this paper introduces a new type of pure mechanical hydraulic over-speed protection device.
