1.产 品 资 料 介 绍：
中文资料：
Woodward 的 PROTECH-GII（型号：8237-2601）是一种超速保护装置，旨在检测涡轮机的超速或过加速事件，并在必要时安全地关闭涡轮机，以防止损坏或安全事故。
主要特点：
高响应速度：该装置的响应时间为 12 毫秒，适用于转速范围从 0.5 至 32,000 rpm 的各种涡轮机类型和尺寸。
冗余设计：提供两种配置选项：
- 双重冗余跳闸继电器输出：采用 2-out-of-3 投票架构，确保高可靠性。
- 三个独立的非投票跳闸继电器输出：每个继电器都有独立的报警功能。
集成与通信：配备 4-20 mA 速度输出和 Modbus 通信接口，方便与其他控制系统集成。
安装选项：提供门板安装和舱壁安装两种方式，适应不同的安装需求。
电源配置：支持高压/高压（HV/HV）或高压/低压（HV/LV）电源输入配置，具有高电源选择性。
应用领域：
PROTECH-GII 适用于蒸汽、燃气和水力涡轮机的超速保护，广泛应用于发电厂和工业设施中，确保涡轮机在超速或过加速情况下的安全停机。
英文资料：
Woodward's PROTECH-GII (model: 8237-2601) is an overspeed protection device designed to detect turbine overspeed or over acceleration events and safely shut down the turbine when necessary to prevent damage or safety accidents.
Main features:
High response speed: The device has a response time of 12 milliseconds and is suitable for various turbine types and sizes with a speed range from 0.5 to 32000 rpm.
Redundant design: provides two configuration options:
Dual redundant trip relay output: adopting a 2-out-of-3 voting architecture to ensure high reliability.
Three independent non voting trip relay outputs: each relay has an independent alarm function.
Integration and Communication: Equipped with 4-20 mA speed output and Modbus communication interface for easy integration with other control systems.
Installation options: Two installation methods are available: door panel installation and cabin wall installation, to meet different installation needs.
Power configuration: Supports high voltage/high voltage (HV/HV) or high voltage/low voltage (HV/LV) power input configurations, with high power selectivity.
Application areas:
PROTECH-GII is suitable for overspeed protection of steam, gas, and hydraulic turbines, and is widely used in power plants and industrial facilities to ensure safe shutdown of turbines in the event of overspeed or over acceleration.
