ORION 過電流保護電驛 (IPR-A)

ORION  過電流保護電驛 ( IPR-A )

 

電流保護電驛 (IPR-A) 乃設計用於正常狀態下或受到干擾時量測線路及接地RMS電流。 透過每條線路的比流器(CT)的感應取得電流信號。該信號經由本電驛微處理器進行處理，以便採取ANSI、IAC或IEC標準所規定的保護措施。 

適用
◐  公用饋線、發電廠及工業配電系統之一次側及備用保護
◐  變壓器、高架線、電纜及發電機等保護

量測項目
◐  (50) Instantaneous overcurrent
◐  (50N/50G) Instantaneous ground overcurrent
◐  (51) Inverse time phase overcurrent
◐  (51N/51G) Inverse time ground overcurrent
◐  ANSI, IAC or IEC/BS142 curves included:
⋄ Moderately inverse
⋄ Normal inverse
⋄ Very inverse
⋄ Extremely inverse
⋄ Definite time
◐  *(46) Negative sequence timed overcurrent
◐  *(79) Reclosing (2 shots)
◐  Overload alarm pickup level
◐  Accumulated kA per phase on breaker interruption
