使用人民電氣BS-60時間繼电器注意事项

2020/7/22 13:24:30      点击:

注意事項:

4.1  延時越短的繼電器越容易整定,實際准確度高,故建議優先選用。特別是采用0.3秒保護時間級差時,應選用延時範圍不大于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,以確保整定值的准確度。

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  長期工作制的産品,在安裝運行和維護中應防止外附電阻及其連接導線接地
