随着人民生活水平的提高,家用电器越来越普及,人们接触电的机会更多了。这里向您介绍一些安全用电的常识。谨防触电住宅中使用的电源,一般是电压为220伏的单相交流电。它是由变电室里的变压器引来的。变压器低压端的220伏电流,通过导线(俗称火线或相线)引向用户,带动家用电器工作,然后再通过导线(零线)返回变压器(图1)。我们的卧室中,一般都设有两个孔的插座。台灯的 With the improvement of people’s living standards, household appliances are becoming more and more popular, and people have more access to electricity. Here to introduce some common sense of safe electricity. Beware of the electric power used in houses that are electrically shocked, typically single-phase AC with a voltage of 220 volts. It is derived from the transformer in the transformer room. The 220 volt current at the low voltage side of the transformer leads to the user through a wire (commonly known as the live wire or phase wire), which drives the home appliance to work and then returns to the transformer through the wire (neutral wire) (Figure 1). In our bedroom, there are generally two holes in the socket. Table lamps
