8237-2596 可配置的超速檢測(cè)系統(tǒng)

protect – gii是一種可配置的超速檢測(cè)系統(tǒng)，用于在檢測(cè)到超速或超速事件時(shí)安全關(guān)閉各種尺寸的蒸汽、天然氣和水輪機(jī)。可在兩個(gè)雙冗余跳閘繼電器輸出使用2-out- 3。

這種快速作用超速保護(hù)裝置被設(shè)計(jì)用于與渦輪機(jī)控制或行程系統(tǒng)一起應(yīng)用，以在渦輪機(jī)超速事件的情況下安全關(guān)閉渦輪機(jī)。與相關(guān)控制系統(tǒng)或工廠DCS(分布式控制系統(tǒng))的接口可以通過protect – gii的冗余硬連線輸入和輸出信號(hào)或通過其三冗余串行Modbus通信端口執(zhí)行。

聯(lián)機(jī)測(cè)試
每個(gè)protect – gii模塊可以從模塊的前面板、Modbus通信端口手動(dòng)測(cè)試，也可以通過其自動(dòng)測(cè)試?yán)坦δ茏詣?dòng)測(cè)試。protect – gii允許用戶配置定期自動(dòng)執(zhí)行超速測(cè)試，一次測(cè)試每個(gè)模塊(a、B、C)，并記錄每次測(cè)試的結(jié)果或停止檢測(cè)到的錯(cuò)誤的測(cè)試。

跳閘，報(bào)警，超速日志
protect – gii日志功能記錄(保存到內(nèi)存中)所有跳閘、告警、跳閘閥響應(yīng)時(shí)間和超速事件。行程日志功能使用滾動(dòng)緩沖區(qū)，并記錄最近50次檢測(cè)到的行程或報(bào)警事件以及最近20次超速事件到內(nèi)存，并附有相關(guān)時(shí)間。每個(gè)日志文件都可以從設(shè)備的前面板查看，或者通過protect – gii服務(wù)工具程序下載到計(jì)算機(jī)上。每個(gè)模塊使用非易失性存儲(chǔ)器來確保所有記錄的事件都被保存，即使在斷電時(shí)也是如此。

實(shí)時(shí)時(shí)鐘
每個(gè)protect – gii模塊采用實(shí)時(shí)時(shí)鐘，以確保準(zhǔn)確的時(shí)間記錄。在模塊之間使用了特殊的時(shí)間平均功能，以確保模塊間的時(shí)鐘同步。

8237-2596 可配置的超速檢測(cè)系統(tǒng)

The ProTech-GII is a configurable overspeed detection system designed to safely shut down steam, gas, and hydro turbines of all sizes upon sensing an overspeed or overacceleration event. Available in two dual redundant trip relay outputs using a 2-out-of-3.

This fast acting overspeed protection device is designed to be applied in conjunction with a turbine control or trip system to safely shut down the turbine in the case of a turbine overspeed event. Interface with related control systems or plant DCS(s) (Distributed Control Systems) can be performed via the ProTech-GII’s redundant hard-wired input and output signals or through its triple-redundant serial Modbus communications ports.

On-line Testing
Each ProTech-GII module can be tested manually from the module’s front panel, Modbus communications port, or automatically via its auto-test routine function. The ProTech-GII allows users to configure an overspeed test to be performed automatically on a periodic basis, testing each module (A, B, C) one at a time, and logging the result of each test or halting the test for a sensed error.

Trip, Alarm, & Overspeed Logs
The ProTech-GII log function logs (saves to memory) all trips, alarms, trip valve response times, and overspeed events. The trip-log function uses a scrolling buffer and records the last 50 sensed trip or alarm events and the last 20 overspeed events to memory, with associated times. Each log file can be viewed from the unit’s front panel, or downloaded to a computer via the ProTech-GII service tool program. Each module utilizes non-volatile memory to ensure that all logged events are saved, even on loss of power.

Real Time Clock
Each ProTech-GII module utilizes a real-time clock to ensure accurate time logging. A special timeaveraging function is utilized between modules to to ensure module-to-module clock synchronization.
