誤接地偵測模組

借助 WAGO 新型誤接地偵測模組，在接地操作模式下，不僅可以檢測 0 V 接地，還可以全自動檢測接地與 +24 V 或 0 V 之間的不可調、不平衡絕緣電阻以下的電阻值的電源電壓。

特點

誤接地偵測模組的演進

單線

發生接地故障時立即熔斷保險絲
立即關閉系統
沒有預警

接地導線斷開接線端子台 - 手動絕緣電阻測試

發生接地故障時立即熔斷保險絲
立即關閉系統
透過日常手動維護檢測潛在的接地故障

誤接地偵測模組 - 自動絕緣電阻測試

誤接地偵測模組提供業界最佳的性價比，並且易於使用。更換以前的接地導線斷開端子台很簡單。僅需將兩條額外的導線連接到 PLC 即可使無電位接點準備好進行評估。

在實際應用中，誤接地偵測模組相對於機械接地導線斷開端子台的優勢

手動測試出現的接地故障被全自動監控取代
檢查間隔大約從3個月減少為10秒
透過無電位接點立即向 PLC 發出進一步信號

應用範例

起點和結果

從接地導線斷開端子台升級為誤接地偵測模組

無論目前在何處使用接地導線斷開端子台，都可以輕鬆改裝誤接地偵測模組以實現全自動監控。

兩個 24 VDC 電源供應器僅需要一個誤接地偵測模組

即使兩個或多個電源供應器並聯，一個誤接地偵測模組也足以進行接地故障監測。
