管廊配電

瀏覽量:
  綜合管廊是設置于地面以下用于容納2種及以上市政管線,設有專門檢修口、吊裝口和監測系統,實施統一規劃、設計、建設和管理的構造物及其附屬設施,是目前城市地下空間開發的重要形式之一。
  城市綜合管廊屬于城市的市政公用設施,是保證城市良好運行的基礎,同時綜合管廊的建設具有一定的不可逆性,因此綜合管廊實施的效果直接影響到城市的發展,所以對于綜合管廊的前期規劃、設計和施工以及后期運營維護都應慎重研究,尤其在設計階段應在規劃的基礎上,全面考慮綜合管廊在全壽命周期內的運行情況,正確使用設計技術,使綜合管廊真正起到城市生命線的作用。
 
 
  綜合管廊配電系統中,其系統接線方案、電源供電電壓、供電點、供電回路數、容量等依據綜合管廊建設規模、周邊電源情況、綜合管廊運營模式,并經技術經濟比較后確定。
  綜合管廊內要求設有消防設備、監控與報警設備、應急照明設備,同時天然氣管道艙內含有監控與報警設備、管道緊急切換閥、事故風機等其他二級負荷設備。由于城市地下綜合管廊的環境特殊性,要求管廊內部電氣設備的防護等級不低于IP54且天然氣管道艙內應安裝防爆設備。就管廊應用的特殊環境,沈陽斯沃依據城市綜合管廊的相關電氣規范,設定了一部分電氣應用推薦方案,用來解決管廊用電設備:
 
 
  在該系統中,配電箱首端采用SIWOQ1系列自動轉換開關產品,S1型控制器同時具備自投自復功能,在開關應用過程中,實時監控兩路電源的電壓、電流、相位及工作狀態檢測。
 
 
  SIWOF系列電氣火災監控系統應用于低壓配電系統中,對管廊設備照明以及動力配電,可能發生火災的電氣線路進行全面監視與控制。能及時報警并提示管理人員消除電氣火災隱患。本系統由電氣火災監控設備、剩余電流式和測溫電氣火災監控探測器、剩余電流探測器組成。產品采用先進的剩余電流檢測技術及過電流反時限報警技術、對其報警值實現連續可調、實時跟蹤,從而提高電氣火災報警的準確度。
