关于各种电气设备进行保安接地(或接零)问题,近年来一些杂志相继发表了一系列文章。但各种观点似有矛盾之处,特别是同一刊物前后发表的文章也出现矛盾,有时要求过严,有时则过松。此外,对“接地”和“接零”的概念也常混淆不清,这就给广大电气工作者和群众造成一些糊涂概念,也给设计工作带来了一定影响。近年来,随着四化建设的不断发展,人民的生活水平逐渐提高,家用电器也日益普及,由于未能 With regard to the problem of grounding (or zeroing) of various electrical equipment, several magazines have successively published a series of articles. However, various viewpoints seem to have contradictions. In particular, the articles published before and after the same publication also appear contradictory, sometimes overly stringent and sometimes too loose. In addition, the concepts of “grounding” and “zeroing” are often confused, which creates some confused concepts for the majority of electrical workers and the masses, and also has a certain impact on the design work. In recent years, with the continuous development of the four modernization projects, people’s living standards have gradually improved and household appliances have become increasingly popular.
