家用电器的漏电保护是涉及广大用户人身安全的重要问题,但是在多数家用电器的实际使用中,漏电保护并未正确地实施。大多数家用电器的用户和部分负责住宅室内电路施工的人员,对家用电器漏电保护的正确方式不甚了解,因此,有必要对这一问题进行研究,以引起社会的重视。1.漏电保护的概念及其基本原理家用电器处于正常状态时,其金属外壳是不带电的。在极少数情况下,电器可能由于种种原因发生漏电现象,外壳就带电了。这时人如果接触电器的外壳,就可能发生触电事故。为避免在漏电时发生触电事故,针对电器的漏电现象采取的保护措施,简称为“漏电保护”。在电器的金属外壳上接出
The leakage protection of household appliances is an important issue involving the personal safety of a large number of users, but in the actual use of most home appliances, the leakage protection is not correctly implemented. Most users of household appliances and those who are responsible for residential indoor circuit construction do not fully understand the correct way of protecting household appliances against electrical leakage. Therefore, it is necessary to conduct research on this issue in order to arouse the attention of the society. 1. The concept of leakage protection and its basic principle When a household appliance is in a normal state, its metal shell is uncharged. In rare cases, electrical leakage may occur due to various reasons, and the enclosure is charged. At this time, if a person touches the housing of the appliance, an electric shock may occur. In order to avoid electric shock accidents at the time of electric leakage, the protective measures taken against electric leakage of electric appliances are referred to as “earth leakage protection”. Take out on the metal housing of the appliance
