只不过此时的电位差相比于220V,要小很多。电压加在电容两端,就会产生微弱电流。所以,火线直接接入电灯,势必导致LED灯闪烁。这属于施工问题,除了改变零火线方向,没有其它办法。可能性2.零线带电电灯(电容)两端都接的是零电位的零线,就万事大吉了吗?也不尽然。零线很容易带电的——特别是电灯的零线。主要是因为电灯开关太不靠谱了。现在的电灯开关,内部结构的质量非常堪忧。零火线接线柱距离太近、绝缘性不合格等,都有可能引起电灯的零线带电。

因此电气灭火必须根据其特点,采取适当措施。切断电源当发生电气火灾时,若现场尚未停电,则首先应想办法切断电源,这是防止扩大火灾范围和避免触电事故的重要措施。切断电源时应该注意以下几点:切断电源是必须使用可靠的绝缘工具,以防操作过程中发生触电事故。切断电源的地点选择要适当,以免影响灭火工作。剪断导线时,非同相的导线应在不同的部位剪断,以免造成人为短路。如果导线带有负荷,应先尽可能消除负荷,再切断电源。防止触电为了防止灭火过程中发生触电事故,带电灭火时应注意与带电体保持必要的安全距离。
