选购ABB断路器时需要参考的几个断路器额定性能

来源:http://www.jntongyu.com/ 日期:2021-05-05 发布人:admin

一.电压和频率

1、 Voltage and frequency
1.额定性能额定工作电压(Ue)
1. Rated performance rated working voltage (UE)
额定性能设备的额定工作电压是电压值,它与额定工作电流相结合,决定了设备的应用以及相关测试和使用类别的参考。
The rated working voltage of the rated performance equipment is the voltage value, which is combined with the rated working current to determine the application of the equipment and the reference of the relevant test and use category.
2.额定性能额定绝缘电压(Ui)
2. Rated performance rated insulation voltage (UI)
额定性能设备的额定绝缘电压是介电测试电压和爬电距离所参考的电压值。在任何情况下,额定工作电压的*大值都不得超过额定绝缘电压的大值。
The rated insulation voltage of rated performance equipment is the reference voltage value of dielectric test voltage and creepage distance. In any case, the maximum value of rated working voltage shall not exceed the maximum value of rated insulation voltage.
3.额定性能额定冲击耐受电压(Uimp)
3. Rated performance rated impulse withstand voltage (Uimp)
额定性能设定的规定形式和极性的冲击电压的峰值,在规定的试验条件下能够承受无故障,并且参考间隙的值。
The peak value of impulse voltage in specified form and polarity of rated performance setting can withstand no fault under specified test conditions, and reference the value of gap.
4.额定性能额定频率
4. Rated performance and rated frequency
额定性能设计设计的供电频率以及其他特征值对应的供电频率。
Power supply frequency of rated performance design and power supply frequency corresponding to other characteristic values.
二.额定性能电流
2、 Rated performance current
⑴额定性能额定不间断电流(In)
(1) rated performance rated uninterrupted current (in)
额定性能断路器的额定不间断电流是断路器在不间断工作期间可以承载的电流值。
The rated uninterrupted current of rated performance circuit breaker is the current value that the circuit breaker can carry during uninterrupted operation.
⑵额定性能额定剩余工作电流(IΔn)
(2) rated performance rated residual working current (I) Δ n)
额定性能这是r.m.s.制造商分配给CBR的正弦剩余工作电流值,CBR应在规定条件下工作。
Rated performance this is the sinusoidal residual working current value assigned to the CBR by the r.m.s. manufacturer and the CBR shall operate under specified conditions.
