一提到安全电压,有人便以为只要使用的电压值符合额定安全电压值,就是绝对安全的。这种认识是十分片面而有害的,在一些场合,使用不符合要求的“安全电压”设备,仍然发生触电事故。其主要原因在于有些人对安全电压及对国家制定的安全电压标准缺乏足够的认识。为了对安全电压的真实含意有一个较全面的认识,下面以安全电压的国家标准为依据,简略谈谈有关的几个问题。安全电压值的确定是一个涉及面很广的综合性问题。它与用电环境、用电设备种类、操作方式等多种因素有关。目前,各国对安全电压值的规定并不完全
When it comes to safety voltage, some people think that as long as the voltage used meets the rated safety voltage, it is absolutely safe. This perception is very unilateral and harmful, in some occasions, the use of substandard “safe voltage ” equipment, there is still an electric shock. The main reason is that some people lack sufficient understanding of the safety voltage and the safety voltage standard set by the state. In order to have a more comprehensive understanding of the true meaning of the safety voltage, the following is based on the national standards for safety voltage, briefly discussing a few related issues. The determination of safety voltage is a comprehensive issue involving a wide range of issues. It and the electricity environment, the type of electrical equipment, mode of operation and other factors. At present, the provisions of the national security voltage values are not complete
