IS200VPROH2B-IS200VPROH1BEF  紧急涡轮保护板

IS200VPROH2B-IS200VPROH1BEF  是GE为Mark VI系统提供的PCB组件。MKVI是通用电气发布的燃气和蒸汽轮机管理系统，是通用电气从MKI开始开发了40多年的Speedtronic生产线的一部分。

IS200VPROH2B-IS200VPROH1BEF  的功能是作为紧急涡轮保护板。与TPRO和TREG板一起，IS200VPROH2B是Mark VI系统的独立超速保护系统。这包括三个VPRO板(三重冗余)，通过TREG板在一个模块中控制行程螺线管，该模块与涡轮控制系统分开。IS200VPROH2B具有9个热电偶输入，用于排气过温保护，以及3个模拟电流输入和备份同步检查保护。

涡轮保护板，如IS215VPROH2B，是GE开发的一种紧急涡轮机保护板。这种保护板与随附的端子板（如TPRO和TREG）共同组成了一个独立的紧急超速保护系统。该保护系统由三个冗余的VPRO板组成，这些板位于与涡轮机控制系统不同的模块中。这个系统使用TREG来调节跳闸电磁阀。此外，VPRO还具有以太网连接，以便与控制模块进行IONet通信。

IS200VPROH2B-IS200VPROH1BEF  紧急跳闸功能由保护模块P中的VPRO板提供。在TREG和TRPG端子板之间，最多可以连接三个跳闸电磁阀。TREG为螺线管提供125V直流电源的正极，而TRPG为负极提供电源。这意味着涡轮机可以通过任一板来跳闸。VPRO板主要提供紧急超速保护和紧急停止功能，确保涡轮机的安全运行。

The IS200VPROH2B-IS200VPROH1BEF is a PCB component provided by GE for the Mark VI system. MKVI is a gas and steam turbine management system released by GE and is part of the Speedtronic product line that GE has been developing for more than 40 years, beginning with MKI.

The IS200VPROH2B-IS200VPROH1BEF functions as an emergency turbine protection board. Together with the TPRO and TREG boards, the IS200VPROH2B is a standalone overspeed protection system for the Mark VI system. This consists of three VPRO boards (triple redundant) that control the travel solenoid via the TREG board in a module that is separate from the turbine control system. The IS200VPROH2B features 9 thermocouple inputs for exhaust overtemperature protection, as well as 3 analog current inputs and backup sync check protection.

Turbine protection panels, such as IS215VPROH2B, are an emergency turbine protection panel developed by GE. Together with the accompanying terminal boards, such as TPRO and TREG, this protection plate forms an independent emergency overspeed protection system. The protection system consists of three redundant VPRO boards located in a separate module from the turbine control system. This system uses the TREG to adjust the trip solenoid valve. In addition, the VPRO has an Ethernet connection for IONet communication with the control module.

IS200VPROH2B-IS200VPROH1BEF Emergency trip function is provided by the VPRO board in the protection module P. Up to three trip solenoid valves can be connected between the TREG and TRPG terminal boards. The TREG supplies the positive side of the 125V DC power supply to the solenoid, while the TRPG supplies the negative side. This means that the turbine can trip through either plate. The VPRO board mainly provides emergency overspeed protection and emergency stop functions to ensure the safe operation of the turbine.
