德國PILZ皮爾茲PSEN系列安全繼電器現(xiàn)貨7電流比對繼電器可靠性的影響：所謂電流比是繼電器的工作負載電流與額定負載電流之比。電流比對繼電器的可靠性影響很大,尤其當電流比大于0.1時,平均故障間隔時間迅速下降,而電流比小于0.1時,平均故障間隔時間基本不變,因此在電路設(shè)計時應選用額定電流較大的負載以降低電流比,這樣可保證繼電器乃至整個電路不因工作電流的波動而使可靠性降低。

1.環(huán)境對繼電器可靠性的影響：繼電器工作在GB和SF下的平均故障間隔時間zui高,達到820000h,而在NU環(huán)境下,僅60000h

2質(zhì)量等級對繼電器可靠性的影響：當選用A1質(zhì)量等級的繼電器時,平均故障間隔時間可達3660000h,而選用C等級的繼電器平均故障間隔時間為110000,其間相差33倍,可見繼電器的質(zhì)量等級對其可靠性能的影響非常大

3觸點形式對繼電器可靠性的影響：繼電器的觸點形式也會對其可靠性產(chǎn)生影響,單擲型繼電器的可靠性都高于相同刀數(shù)的雙擲型繼電器,同時隨刀數(shù)的增加可靠性逐漸降低,單刀單擲繼電器的平均故障間隔時間是四刀雙擲繼電器的5.5倍

4結(jié)構(gòu)類型對繼電器可靠性的影響：繼電器結(jié)構(gòu)類型共有24種,不同類型均對其可靠性產(chǎn)生影響

5溫度對繼電器可靠性的影響：繼電器工作溫度范圍在-25～70℃之間。隨著溫度的升高,繼電器的平均故障間隔時間逐漸下降

6動作速率對繼電器可靠性的影響：隨著繼電器動作速率的提高,平均故障間隔時間基本呈指數(shù)型下降趨勢因此,若設(shè)計的電路要求繼電器的動作速率非常高,那么在電路維修時就需要仔細檢測繼電器以便及時對它更換
