2301E 8273-1011负载共享控制 控制柴油或气体发动机驱动

产品描述

8273-1011 是可用于控制蒸汽轮机的多种 Woodward 505 数字调速器之一。该操作员控制面板充当图形界面和键盘，允许对涡轮机进行调整并与涡轮机通信。这可以通过设备上的 Modbus 通信端口进行配置。  

8273-1011 具有多种可用功能：

热启动和冷启动的自动启动顺序，具有温度输入选项

三速带上的临界速度避免

十个外部报警输入

十个外部 DI 跳闸输入

带有相关 RTC 时间戳的跳闸和警报事件的跳闸指示

双速度和负载动态

超速跳闸的峰值速度指示

零速检测

远程下垂

频率死区

该装置还提供三种正常操作模式，包括配置、操作和校准模式。 

该装置包括两个冗余速度输入，可接受磁性拾取装置、涡流探头或接近探头。它具有模拟输入 (8)，可配置为二十七个功能中的任何一个。该装置还有另外 20 个触点输入。这些触点中的前四个默认用于关闭、升高速度设定值、复位和降低速度设定值。其他的可以根据需要配置。此外，该装置还具有两个 4-20 mA 控制输出和八个 C 型继电器触点输出。

8273-1011 的前面板包括紧急跳闸键、退格/删除键、Shift 键以及视图、模式、ESC 和 Home 键。它还具有导航十字键、软键命令和四个用于关联控制和硬件状态的 LED。

Product description

The 8273-1011 is one of a variety of Woodward 505 digital governors that can be used to control steam turbines. The operator control panel acts as a graphical interface and keyboard, allowing the turbine to be adjusted and communicated with. This can be configured via the Modbus communication port on the device.

The 8273-1011 has several available functions:

Automatic start sequence for hot start and cold start, with temperature input option

Three speed belt to avoid critical speed

Ten external alarm inputs

Ten external DI trip inputs

Trip indication of trip and alert events with relevant RTC time stamps

Dual speed and load dynamics

Peak speed indication of overspeed trip

Zero speed detection

Long range sag

Frequency dead zone

The unit also offers three normal operation modes, including configuration, operation and calibration modes.

The device includes two redundant speed inputs and can accept a magnetic pickup device, eddy current probe, or proximity probe. It has analog inputs (8) and can be configured for any of twenty-seven functions. The device also has an additional 20 contact inputs. The first four of these contacts are used by default to close, raise the speed setpoint, reset, and lower the speed setpoint. Others can be configured as needed. In addition, the unit has two 4-20 mA control outputs and eight Type C relay contact outputs.

The front panel of the 8273-1011 includes the Emergency trip key, the backspace/Delete key, the Shift key, and the view, Mode, ESC, and Home keys. It also has navigation cross keys, soft key commands, and four leds for associating control and hardware status.
