1993年,我国等效采用国际基本标准IEC1201,发布了我国的有关电气安全的一项基础标准GB/T3805-93《特低电压限值》,把对人没有危险的电压限值,由仅凭经验数据、传统称呼的安全电压推进了具有科学依据的符合国际惯例的特低电压限值时代。对于内阻比人体阻抗低得多的电源以及其所提供的,对人没有危险的电压限值的主要内容已例入下表。在具体应用中必须留有裕量;大于100Hz电源的情况需要另行研究;
In 1993, China adopted the equivalent of the international basic standard IEC1201, which issued a basic standard GB / T3805-93 “Extra Low Voltage Limit” of our country on electrical safety. The voltage limit that is not dangerous to human beings is determined by Experience data, the traditional name of the safe voltage to promote a scientifically based ultra-low voltage limit in line with international practice era. For the power supply with a much lower internal impedance than the human body impedance and the non-hazardous voltage limits it provides, the following table is included. In specific applications must leave margin; greater than 100Hz power needs to be studied separately;
