IS200TSVOH2B 伺服控制板 输出电压电流继电器均通过诊断进行监控

GE IS200TSVOH2B 伺服控制板的操作：LVDT 位置反馈、LVDT 激励、双向伺服电流输出和脉冲率流量输入均包含在 VSVO 的四个通道中。TSVO zui多可以提供六个 LVDT 阀位输入的激励，TSVO 也接受来自这些输入的输入。对于每个伺服控制环路，可以选择一个、两个、三个或四个 LVDT。对于测量燃气轮机流量的应用，提供了三个输入。

这些信号通过 TSVO 并直接发送到 VSVO 板正面的 J5。断电时，每个伺服输出都有一个专用自杀继电器，在由固件控制时，会将 VSVO 输出信号短接到公共信号，然后根据手动复位指令返回正常操作。每个伺服系统的输出电压、电流和自杀继电器均通过诊断进行监控。


IS200TSVOH2B是通用电气制造的  伺服控制板，属于燃气轮机控制系统中使用的 Mark VI 系列的一部分。操作蒸汽/燃料阀的四个电液伺服阀在伺服控制板的指导下。通常，使用两个伺服端子板来分隔这四个通道（TSVO 或 DSVO）。使用线性可变差动变压器确定阀门位置 (LVDT)。 执行环路控制算法。在前面板上的 J5 插头和 VME 机架上的 J3/J4 连接器上，三根电缆连接到 。JR1 连接器用于TSVO 提供单工信号，而 JR1、JS1 和 JT1 连接器用于扇出 TMR 信号。将保护模块的外部跳闸插入 JD1 或 JD2。

Operation of the GE IS200TSVOH2B servo control board: LVDT position feedback, LVDT excitation, two-way servo current output and pulse rate flow input are contained in the four channels of the VSVO. TSVO can provide excitation for up to six LVDT valve position inputs, and TSVO also accepts inputs from these inputs. For each servo control loop, you can choose one, two, three, or four LVDTS. For applications measuring gas turbine flow, three inputs are provided.

These signals pass through TSVO and are sent directly to J5 on the front of the VSVO board. In case of power failure, each servo output has a dedicated suicide relay that, when controlled by the firmware, shorts the VSVO output signal to the public signal and then returns to normal operation according to manual reset instructions. The output voltage, current and suicide relays of each servo system are monitored through diagnostics.


The IS200TSVOH2B is a servo control board manufactured by General Electric and part of the Mark VI family used in gas turbine control systems. Four electro-hydraulic servo valves operate the steam/fuel valves under the guidance of the servo control board. Typically, two servo terminal boards are used to separate these four channels (TSVO or DSVO). The valve position is determined using a linear variable differential transformer (LVDT). Execute the loop control algorithm. On the J5 plug on the front panel and the J3/J4 connector on the VME rack, three cables are connected to. JR1 connectors are used for TSVO to provide simplex signals, while JR1, JS1, and JT1 connectors are used for fan-out TMR signals. Plug the external trip of the protection module into JD1 or JD2.
