1 概况General

现在已广泛使用“ 标准化PLC微机调节器+电液随动系统” 结构模式的新型微机调速器系统，由微机调节器部分完成信号传递、调节规律的综合、调节参数切换、状态指示、控制量的输出等功能，机械液压部分采用电液随动系统，纯粹将机械液压部分作为功率放大、进行随动控制的执行机构；发挥各自长处，提高了调节系统的性能和设计、使用等方面的灵活性。

The new type microcomputer-based governor system consisted of “standard PLC regulator + electro-hydraulic servo system” is now widely used. The microcomputer regulator section can execute following functions, such as signal transmission, regulating rule synthesize , regulating parameter switch, status indication, the output of control value,etc. The mechanical-hydraulic section adopt the eletro-hydraulic servo system, it simply works as a power amplifier and servo control actuator. The new type microcomputer-based governor system can improve the performance and the flexibility of use.

本手册为CVZT－150数字式水轮机调速器的原理与使用说明。 CVZT-150是基于现代液压数字逻辑插装技术而开发的一类新型调速器，其型号定义如下：

This manual will describe the princilpe and operating about the CVZT-150-6.3 digital hydraulic turbine governor. The CVZT-150 governor is a new type governor based on the modern hydraulic digital logic cartridge technology. Its model number are defined as follows,

CVZT-150-6.3 Pressure grade code code, also called main valve diameter Double regulating governor for large turbine diameter

该类调速器采用逻辑插装技术，由高速开关阀与逻辑插装阀等标准液压件进行元件-组件-回路的多层次组合与优化设计，进而实现调速器调节与控制的所有功能。它突破了近一个世纪以来一成不变的电气-机械/液压转换元件（电液转换器或微型电机等） + 主配压阀的经典形式、以及制造工艺与结构布置等方面的种种制约，系统的调节、控制无需由“中间位置”与机械反馈来保证，使调速器的设计、制作与生产发生了根本性的变化；它兼顾了机械液压动作的可靠性、微机的适用性和阀的简单化。具有高可靠性、响应快、动作平稳性好、定位精度高、工作效率高、节省油源消耗等独特优点，在调速器领域独树一帜。

This type governor is based on logic cartridge technology, that is combined with high

speed on-off valve and cartridge valve,via multi-level manifold block combination and optimal design from components to subassembly to fluid loop, then proceed to realize all the regulating and control functions of governor. It has successfully breached the constraint of classic structure with electrical-mechanical/hydraulic conveter or micro-motor plus main distributing valve, and it has also broken through the constraint of manufacturing process and structural arrangement. It is without the necessity for “middle position” and mechanical feedback to ensure the regulating and control of system. That enable the design and manufacture of governor to be a fundamental change. It make a compromise the motion reliability of mechanical hydraulic section, applicability of micro-computer,and simplification of valve. It has unique advantages of high reliability, quick response, smooth motion, and high precision of positioning, high motion efficiency, save oil consumption,etc. It is unique and place a position in the field of governor.
