要知道直流屏的基本組成，要先弄清楚什么是直流屏？它是直流電源操作系統(tǒng)的簡稱。通常被稱為智能免維護(hù)直流電源屏，直流屏是一種簡稱。它是用來供應(yīng)型號為GZDW的直流電源的。廣泛應(yīng)用在發(fā)電廠和變電站的電力操作系統(tǒng)中，為動力負(fù)荷和控制負(fù)荷以及直流故障照明負(fù)荷等提供直流電源。是當(dāng)代電力系統(tǒng)控制、保護(hù)的基礎(chǔ)。 </p> <p> 直流屏由整流模塊系統(tǒng)、配電單元、降壓單元、電池巡檢單元、開關(guān)量檢測單元、監(jiān)控系統(tǒng)、絕緣監(jiān)測單元組成。當(dāng)然也有的是按照交配電單元、充電模塊單元、降壓硅鏈單元、直流饋電單元、配電監(jiān)控單元、監(jiān)控模塊單元及絕緣監(jiān)測單元這七塊來劃分直流屏的功能區(qū)的。還有的是按照由機柜、整流模塊系統(tǒng)、監(jiān)控系統(tǒng)、絕緣監(jiān)測單元、電池巡檢單元、開關(guān)量檢測單元、降壓單元及一系列的交流輸入、直流輸出、電壓顯示、電流顯示等配電單元。不管是哪一種構(gòu)成分類，它們組合在一起，是一個整的直流電源操作系統(tǒng)。所起的作用都是一樣的。不可避免地在直流穩(wěn)定量多少和一些交流成份,這種疊加在直流穩(wěn)定量上的交流分量稱為漣漪。安順低壓直流屏報價</p><p

直流屏是一種全新的數(shù)字化控制、保護(hù)、管理、測量的新型直流系統(tǒng)。監(jiān)控主機部分高度集成化，采用單板結(jié)構(gòu)（Allinone），內(nèi)含絕緣監(jiān)察、電池巡檢、接地選線、電池活化、硅鏈穩(wěn)壓、微機**信號等功能。主機配置大液晶觸摸屏，各種運行狀態(tài)和參數(shù)均以漢字顯示，整體設(shè)計方便簡潔，人機界面友好，符合用戶使用習(xí)慣。 </p> <p> 直流屏系統(tǒng)為遠(yuǎn)程檢測和控制提供了強大的功能，并具有遙控、遙調(diào)、遙測、遙信功能和遠(yuǎn)程通訊接口。通過遠(yuǎn)程通訊接口可在遠(yuǎn)方獲得直流電源系統(tǒng)的運行參數(shù)，還可通過該接口設(shè)定和修改運行狀態(tài)及定值，滿足電力自動化和電力系統(tǒng)無人值守變電站的要求；配有標(biāo)準(zhǔn)RS232/485串行接口和以太網(wǎng)接口，可方便納入電站自動化系統(tǒng)。安順低壓直流屏報價</p><p
