>>>>>型號(hào):8200-1302 數(shù)字調(diào)速器 充當(dāng)圖形界面和鍵盤
【功能描述】
8200-1302 是可用于控制汽輪機(jī)的幾款伍德沃德 505 數(shù)字調(diào)速器之一。該操作員控制面板充當(dāng)圖形界面和鍵盤，允許對(duì)渦輪機(jī)進(jìn)行調(diào)整并與之通信。這可以通過位于設(shè)備上的 Modbus 通信端口進(jìn)行配置。
8200-1302 具有多種可用功能：
熱啟動(dòng)和冷啟動(dòng)的自動(dòng)啟動(dòng)順序，具有溫度輸入選項(xiàng)
三速頻段的臨界速度規(guī)避
10 個(gè)外部報(bào)警輸入
10 個(gè)外部 DI 跳閘輸入
具有相關(guān) RTC 時(shí)間戳的跳閘和報(bào)警事件的跳閘指示
雙速度和負(fù)載動(dòng)態(tài)
超速跳閘的峰值速度指示
零速檢測(cè)
遠(yuǎn)程壓降
頻率死區(qū)
該裝置還提供三種正常工作模式，包括配置、操作和校準(zhǔn)模式。
該裝置包括兩個(gè)冗余速度輸入，可以接受磁性拾取裝置、渦流探頭或接近探頭。它具有模擬輸入 （8），可針對(duì) 27 種功能中的任何一種進(jìn)行配置。該裝置還具有額外的 20 個(gè)觸點(diǎn)輸入。這些觸點(diǎn)中的前四個(gè)觸點(diǎn)默認(rèn)用于關(guān)斷、提高速度設(shè)定點(diǎn)、復(fù)位和降低速度設(shè)定點(diǎn)。其他的可以根據(jù)需要進(jìn)行配置。此外，該裝置還具有兩個(gè) 4-20 mA 控制輸出和八個(gè) Form-C 繼電器觸點(diǎn)輸出。

【英文介紹】
The 8200-1302 is one of several Woodward 505 digital governors available 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 a Modbus communication port located on the device.
The 8200-1302 has a variety of functions available:
Automatic start sequence for hot start and cold start, with temperature input option
Critical speed evasion in the three-speed band
10 external alarm inputs
10 external DI trip inputs
Trip indication with associated RTC time stamps and alarm events
Dual speed and load dynamics
Peak speed indication of overspeed trip
Zero speed detection
Long range voltage drop
Frequency dead zone
The unit also offers three normal operating 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 the 27 functions. The device also has an additional 20 contact inputs. The first four of these contacts are used by default to turn off, raise speed setpoints, reset, and lower speed setpoints. Others can be configured as needed. In addition, the unit has two 4-20 mA control outputs and eight Form-C relay contact outputs.
