注意事項

4.1  延時越短的繼電器越容易整定,實際準確度高,故建議優先選用。特別是采用0.3秒保護時間級差時,應選用延時范圍不大于5秒的繼電器。

4.2  做延時整定時,應注意兩次通電動作之間,要留有一定的間隔時間,以確保整定值的準確度。

4.3  帶有電流保持回路的繼電器,使用時注意工作電壓與自保持電流回路同極性 (電壓、電流回路極性見圖3端子接線圖)。如果極性反,易將電流回路觸點損壞。

4.4  繼電器在工作過程中,應定期檢查它的出口觸點,若有燒毀,應檢查開關輔助觸點是否斷開過慢。

4.5  長期工作制的產品,在安裝運行和維護中應防止外附電阻及其連接導線接地。

該系列時間繼電器(以下簡稱繼電器)作為延時控制元件,用于電力系統繼電保護裝置及自動化裝置中,使被控設備或電路按照預定的延時動作。
主要特點如下:
a.具有較高的延時準確性?梢詫㈦A段式繼電保護的級差壓縮為0.3s。
b.可靠性強,不存在發卡拒動的問題,并已取得大量的成功運行經驗。
c.配置了電流自保持觸點,有利于直接接通跳閘回路。
d.通用性強。該繼電器采用與DS—110系列時間繼電器相同的外殼,并充分考慮了端子接線與上述繼電器的對應關系。因此,可以方便地進行互換使用。
