8237-1247 监控涡轮转子速度和加速度 WOODWARD

【产品详情】

8237-1247 通过主动或被动 MPU 监控涡轮转子速度和加速度，并向涡轮机的跳闸阀或相应的跳闸系统发出停机命令。

型号8237-1247是伍德沃德ProTech-GII系列的一部分。该隔板支架用于检测各种类型涡轮机中的超速。它可以配置为与水轮机、蒸汽轮机和燃气轮机配合使用，以便在过度加速时安全地关闭它们。它具有 4 至 20 mA 的速度读数，并使用 Modbus 通信。伍德沃德已停产 8237-1247 型，但仍可通过 AX Control 获得。该产品可以安装在标准机柜门中，并使用两个冗余脱扣继电器。它使用高压和高压电源输入。

8237-1247 型除了耐 H2S 和 CO2 气体外，还耐硫污染。它具有三重模块化设计，可以在运行时更换三个模块中的一个。该产品可以配置为在每个模块上运行例行测试，以确保过度尿液检测正常工作。常规测试通过发电机产生的内部频率完成。它还利用 MPU 检测。

【英文介绍】

The 8237-1247 monitors turbine rotor speed and acceleration via an active or passive MPU and issues a stop command to the turbine's gate jump valve or corresponding trip system.

Model 8237-1247 is part of the Woodward ProTech-GII series. The diaphragm bracket is used to detect overspeed in various types of turbines. It can be configured to work with water, steam and gas turbines to safely shut them down in case of excessive acceleration. It has speed readings from 4 to 20 mA and communicates using Modbus. Woodward has discontinued the 8237-1247, but it is still available through AX Control. The product can be installed in a standard cabinet door and uses two redundant trip relays. It uses high voltage and high voltage power inputs.

Type 8237-1247 is resistant to sulfur pollution in addition to H2S and CO2 gases. It has a triple modular design that allows one of the three modules to be replaced at run time. The product can be configured to run routine tests on each module to ensure that excessive urine detection is working properly. Routine testing is done with the internal frequency generated by the generator. It also utilizes MPU detection.
