9907-084 每个速度探头的实际速度 超速检测

【产品详情】

伍德沃德的 9907-084 ProTech 203 显示每个速度探头的实际速度，显示最高速度信号，以及采用模块化设计的在线测试。该系列具有热更换模块

全系统跳闸依赖于 9907-084 型中三个独立速度传感单元中两个的超速检测。单次跳闸单元不会使原动机脱机。在系统运行时对设备进行热更换和测试是这种三分之二的投票者中继配置所启用的一些功能。该系列器件使用磁性拾音器来监控原动机速度，执行三个单独的速度计算，并在检测到超速条件时激活跳闸继电器。

ProTech 9907-084 的速度感应单元，每个都有自己的 120 Vac/dc 电源，位于一个钥匙锁定、IP 65 认证的外壳中。此外壳的前面板上是每个单元的操作员界面。

使用每个接口上的LCD和键盘设置五个可调参数。跳闸速度设定点、MPU 故障跳闸、MPU 故障超时、MPU 故障设定点和 MPU 齿轮齿为每个速度感应单元单独编程，但必须针对相同的跳变点设置它们。Woodward ProTech 手册 85203 包含完整的编程详细信息以及协助此步骤的编程工作表。

【英文介绍】

Woodward's 907-084 ProTech 203 displays the actual speed of each speed probe, displays the maximum speed signal, and uses a modular design for online testing. The series has a hot replacement module

The full system trip relies on overspeed detection by two of the three independent speed sensing units in the Model 9907-084. The single trip unit does not take the prime mover offline. Hot replacement and testing of equipment while the system is running are some of the features enabled by this two-thirds voter relay configuration. This family of devices uses magnetic pickups to monitor the prime mover speed, perform three separate speed calculations, and activate trip relays when overspeed conditions are detected.

The ProTech 9907-084 speed sensing units, each with their own 120 Vac/dc power supply, are housed in a keylocked, IP 65-certified housing. On the front panel of this housing is the operator interface for each unit.

Set five adjustable parameters using the LCD and keyboard on each interface. Trip speed set point, MPU fault trip, MPU fault timeout, MPU fault set point, and MPU gear teeth are individually programmed for each speed sensing unit, but they must be set for the same jump point. Woodward ProTech manual 85203 contains complete programming details as well as programming worksheets to assist with this step.
