- 摘要:
- 触电形式、触电防护措施、供电系统的选择属于触电防护的基本问题。就触电形式而言，存在分类不完整、不同分类之间缺乏联系等问题，从触电相关导电体着手，提出了多层次系统化触电形式分类方法。就触电防护措施而言，就IEC最新标准由“平面式”分类转向“立体式”分类的深层意义进行了解读，并对“立体式”分类方法仍存在的问题进行了分析，提出了改进建议；指明我国翻译制定的等同标准未能充分体现IEC“立体式”分类方法的真正用意。就供电系统选择而言，“只能借用过流保护装置完成漏电保护”时代已经结束，建议我国从标准层面上放弃对TN供电系统的推荐，积极推广TT系统。
- Abstract:
- Electric shock forms and its protective measures, the choice of the power distribution systems are basic problems of protection against electric shock. As for electric shock forms, there are problems such as the classification is not complete and the relationship between different classification methods has not been established. Starting from the conductors concerned with electric shock, a multilayer systematic classification method was given. As for electric shock protection measures, an interpretation to the deep significance of the change of IEC standards from a “plane” classification method to a “cubic” one was made, and the problems still existing in the “cubic” classification method were pointed out and some improvement suggestions were presented. Also, it was pointed out that the real significance of the “cubic” classification method had hot been expressed precisely by the Chinese equistandard. As for the choice of power distribution systems, for the time of “having to borrow an overcurrent protection device to finish protection against current leakage faults” had gone, a suggestion to the standards and codes of China to give up highlighting TN system and to turn to the TT system was put forward.
