Residual current operated circuit-breakers for household and similar use - Part 3-1: Particular requirements for RCDs with screwless-type terminals for external copper conductors
发布时间:2016-09-07 实施时间:


剩余电流动作断路器是一种用于保护人员免受电击的电气设备。当电路中的电流超过设定值时,RCD会立即切断电源,以防止电击事故的发生。螺纹式端子是一种常见的连接器,它可以使电线更容易地连接到设备上。外部铜导体是指连接到RCD的铜导线。

IEC 62873-3-1:2016标准规定了RCDs的额外要求,以确保它们的安全性和可靠性。这些要求包括:

1. 螺纹式端子的设计和尺寸必须符合标准要求,以确保连接的可靠性和安全性。

2. RCD必须能够承受额定电流和额定电压下的负载,并能够在短时间内切断电源。

3. RCD必须具有过载和短路保护功能,以防止设备过载或短路时发生火灾或其他危险。

4. RCD必须具有防止误动作的功能,以防止不必要的断电。

5. RCD必须具有防止电弧的功能,以防止电弧引起的火灾或其他危险。

6. RCD必须具有防止电磁干扰的功能,以确保其正常工作。

7. RCD必须具有防止温度过高的功能,以防止设备过热或烧毁。

8. RCD必须具有防止潮湿和污染的功能,以确保其正常工作。

除了这些要求之外,IEC 62873-3-1:2016还规定了RCD的测试和检验要求,以确保其符合标准要求。这些测试和检验包括:

1. 额定电流和额定电压测试

2. 过载和短路测试

3. 误动作测试

4. 电弧测试

5. 温度测试

6. 潮湿和污染测试

7. 绝缘测试

8. 耐电压试验
