9905-751 显示最高速度信号 超速保护装置
【产品详情】
伍德沃德的ProTech 203 9905-751显示每个速度探头的实际速度，显示最高速度信号，以及模块化设计的在线测试。该系列具有热更换模块
203-9905由伍德沃德在该公司的ProTech 751系列超速保护装置中制造，是一种断电跳闸型号。该器件使用三个速度感应单元，每个单元与单独的磁性拾音器（MPU）接口，以监控原动机速度。这些几乎相同的单元配置为硬件三分之二的投票。原动机速度每 5 ms 采样一次，最大系统响应时间为 40 ms。 单元 A 和 B 具有 24Vdc 输入，而单元 C 具有 120 Vac/dc 输入。
三个速度感应单元位于一个经过 NEMA 4X 认证的外壳中，该外壳是钥匙锁定的。型号 9905-751 的编程只能通过钥匙锁访问进行。可调参数和其他编程规范和说明在ProTech 203超速保护系统手册85196中。
每个单元都有自己的前面板，包括：
触摸板
双行 16 字符 LCD 显示屏
单独的 LED 功能状态指示灯，用于显示 MPU/接线故障、CPU 在正常参数之外运行以及设备跳闸
有许多情况可能会促使 9905-751 机组之一跳闸，例如速度超过跳闸设定值、MPU 故障超时或在重新启动涡轮机之前没有复位。有关这些情况和其他情况的故障排除详细信息，请参阅产品手册。

【英文介绍】
Woodward's ProTech 203 9905-751 displays the actual speed of each speed probe, displays the maximum speed signal, and online testing of the modular design. The series has a hot replacement module
Manufactured by Woodward in the company's ProTech 751 series of overspeed protection devices, the 203-9905 is a power-off trip model. The device uses three speed sensing units, each of which interfaces with a separate magnetic pickup (MPU) to monitor the prime mover speed. These nearly identical units are configured for hardware two-thirds of the vote. The prime mover speed is sampled every 5 ms and the maximum system response time is 40 ms. Units A and B have 24Vdc inputs, while unit C has 120 Vac/dc inputs.
The three speed sensing units are housed in a NEMA 4X certified housing that is keylocked. Model 9905-751 programming can only be done with key lock access. Adjustable parameters and other programming specifications and instructions are found in ProTech 203 Overspeed Protection System Manual 85196.
Each unit has its own front panel, including:
touchpad
Two-line 16-character LCD display
Separate LED function status indicators for MPU/ wiring failures, CPU operating outside normal parameters, and device tripping
There are a number of conditions that could cause one of the 9905-751 units to trip, such as speed exceeding the trip setpoint, MPU failure timeouts, or failure to reset before restarting the turbine. For troubleshooting details on these and other conditions, refer to the product manual.
