NAAS DC Circuit Breaker Ampere Second Characteristic Tester  NAAS直流斷路器安秒特性測試儀

產品簡介

隨著國民經濟的飛速發展，民用和工業用電量的急劇增大，保障國家電網的安全運行工作越來越重要，在電力系統中，直流電源系統作為繼電保護、自動裝置、控制操作回路、燈光音響信號及事故照明等電源之用。

目前國內進行直流斷路器安秒特性檢測的機構和生產廠家用于直流空開安秒特性檢測的設備均為固定設備，如固定的大電流電源、大型負載電阻，體積大、重量大，不便于移動檢測，分析儀表均為常規儀表如電壓表、電流表、示波器等，接線復雜，使用不便，不適應各變電站移動檢測需要。為解決現場對直流斷路器實際特性檢測的問題，南澳電氣推出了一種適合變電站現場使用、便于攜帶、自動化程度高的"NAAS直流斷路器安秒特性測試儀"，可以為運行維護部門提供直流保護電器動作特性的測試手段，對直流保護電器的動作特性以及級差配合進行校驗，以便提高直流系統運行的可靠性，保證電網的安全可靠運行。

NAAS直流斷路器安秒特性測試儀是專為變電站試驗、檢修、維護工作而設計。滿足直流斷路器的超載和短路特性測試，從而提高變電站直流系統的健康水平，避免直流配電網絡出現越級跳閘和引發的大面積停電事故。
