SEL 487B 87B保護電驛
The SEL-487B Relay provides bus current differential protection, circuit breaker failure protection, and
backup overcurrent protection. The relay has 18 analog current inputs and three analog voltage inputs. For
buses with no more than six terminals, use one SEL-487B in a single-relay application. For buses with seven
to nine terminals, use two SEL-487B relays. For buses with up to 18 terminals, use three SEL-487B relays;
each relay provides up to six dedicated zones of protection.

SEL-2652 開關跳脫迴路監視單元(Trip Coil Monitor)
SEL-2652 開關跳脫迴路監視單元(Trip Coil Monitor,Trip Coil Supervision )
應用SEL-2652跳脫線圈監控器來監視斷路器或Lockout Relay 跳脫線圈以及跳脫電路的正常性。避免因為跳脫迴路故障,造成開關的ON/OFF失常,因而產生跳電範圍及損失擴大。 通過外部LED顯示斷路器狀態或連續性狀態,並通過C觸點向SCADA報告狀態。
SEL-2652 開關跳脫迴路監視單元,不像其他電驛需外加電阻才能達到跳脫迴路監視功能,因此不會因為電阻器故障或短路造成跳電.
➤無需庫存其他跳閘線圈監視器,適應各種開路電壓(48至125 Vdc)。
➤快速檢測斷路器狀態(SEL-2652A)或連續性狀態(SEL-2652B)使用紅色可見光和藍色。
➤使用方便的遠程指示輕鬆監控跳閘電路正常斷路器運行時不會出現令人討厭的警報的狀況操作。
➤使用這種堅固耐用的設備來減少維護工作經過變電站環境測試。
➤使用面板安裝設計和Connectorized®在幾分鐘內安裝接線端子。
CAMTO弧光偵測電驛(系統) Arc Detection Relay
Major highlights of the new ARC-detector unit from Camto A/S type: 601E0100 & 601E0900:
Input voltage: 9-32VDC (601E0100) 110Vac/230Vac (601E0900)
Four individual detector zones
Unlimited numbers of sensors for each sensor zone
The possibility of series connection of sensors in the same zone (savings on sensor cables
and installation costs)
100% self-test feature option; even tests of the optical parts are included
Pre-detection of small levels of fault
Simple serie code output for event status (PLC interface)
Trip coil outputs as latched and open contacts
Combination of sensor types like smoke, ARC, humidity, temperature and levels are
available
Standard DIN unit with spring terminals
Realtime eventlog with time and date information for fault status
Simple PC interface (MSP) for monitor and setting use
Low unit and installation costs
