1. 系统概述
1 General Description Of The System
汽轮机安全监测仪表系统（Turbine Supervisory Instrument，简称TSI）是一种可靠的连续检测汽轮发电机转子和汽缸的机械工作参数的多路监控系统，可以显示机组状态，为记录仪和计算机系统提供输出信号，并在超出预置的运行极限时发出报警，此外，还能使汽轮机自动停机和提供用于诊断性估算的各种测量数据。
Turbine Supervisory Instrumentation ( Turbine Supervisory Instrumentation , referred to as the TSI ) system is a reliable continuous detection of mechanical operating parameters of the turbine generator rotor and cylinder multi-channel monitoring system that can display unit provides analog output signals for the recorder and computer systems. TSI also output digital signals for alarm and trip when the input signals exceed the limit.
本机组TSI采用的是BENTLEY3500系列模件。 This site use the 3500 series modules form BENTLEY.
该保护系统设计有冗余的电源模件，由双路电源供电，任一路电源丧失可发出报警，保证系统安全可靠。
The protection system is provided with a redundant power supply module and is powered by double passage power supply. Alarm can be issued when any one power supply is lost to ensure safety and reliability of the system.
TSI的测量回路是由探头、前置放大器、插件式组装仪表等组成。探头和前置器在出厂前已成套进行了线性校准，安装时要成套安装。
Measurement loop of TSI consists of probe, front-mounted amplifier and socket type assembly instruments. Linear calibration is carried out on probe and front-mounted amplifier before leaving the factory and they should be installed in set.
2. 编制目的
