摘要
GB 9706.1—2020相较于GB 9706.1—2007在标准名称和结构上发生了重大的变化,对电击防护新增了很多内容。借鉴了GB 4943.1的安全理念,引入了多重因素,综合考量ME设备的爬电距离和电气间隙。论文通过对GB 9706.1—2020标准与我国现行标准GB 9706.1—2007关于爬电距离和电气间隙测试的差异分析,以期对相关产品的研发和设计及检测实验室的检测能力储备提供一些借鉴作用。
Compared with GB 9706.1—2007,GB 9706.1—2020 has great changes in the name and structure of the standard,and a lot of new contents have been added to electric shock protection.Based on the safety concept of GB 4943.1,multiple factors are introduced to comprehensively consider the creepage distance and air clearance of ME equipment.This paper analyzes the differences between GB 9706.1—2020 and current Chinese standard GB 9706.1—2007 on creepage distance and electrical clearance test,in order to provide some reference for the research and development and design of related products and the testing capacity reserve of testing laboratories.
