Masterpact MTZ空气断路器解决方法:
MTZ框架断路器的电流整定范围如下所示:
MIC2.0B:长延时电流整定Ir=In x...( 0.4 0.5 0.6 0.7 0.8 0.9 0.95 0.98 1.0)
瞬时整定值Isd = Ir x …(1.5 2 2.5 3 4 5 6 8 10)
MIC2.0X:长延时电流整定Ir=0.4In~In,整定步长1A
瞬时整定值Isd=1.5~10Ir, 整定步长0.5倍Ir
MIC5.0B:长延时电流整定Ir=In x...( 0.4 0.5 0.6 0.7 0.8 0.9 0.95 0.98 1.0)
短延时整定值Isd = Ir x …(1.5 2 2.5 3 4 5 6 8 10) (5.0B/6.0B设置一致)
瞬时整定值Ii = In x …(2 3 4 6 8 10 12 15 OFF) (5.0B/6.0B设置一致)
MIC5.0X:长延时电流整定Ir=0.4In~In,整定步长1A
短延时整定值Isd=1.5~10Ir, 整定步长0.5倍Ir(5.0X/6.0X/7.0X设置一致)
瞬时整定值Ii=2In~15In,整定步长0.5In和关闭 (5.0X/6.0X/7.0X设置一致)
MIC6.0B: 接地故障整定值(A)Ig = In x …
Ig = In x | A | B | C | D | E | F | G | H | J |
In ≤ 400A | 0.3 | 0.3 | 0.4 | 0.5 | 0.6 | 0.7 | 0.8 | 0.9 | 1.0 |
400 < In < 1250A | 0.2 | 0.3 | 0.4 | 0.5 | 0.6 | 0.7 | 0.8 | 0.9 | 1.0 |
In ≤ 1250A | 500 | 640 | 720 | 800 | 880 | 960 | 1040 | 1120 | 120 |
MIC6.0X:Ig=0.2 In~In,整定步长0.1In和关闭(当In≤400A时,为0.3In~In)
MIC7.0X:灵敏度 (A) IΔn= 0.5A~30A,整定步长0.1A
使用Ecoreach软件和Masterpact MTZ移动应用可以对Ir/Isd/Ig(MIC X)进行更精细的步长整定。
