我国牵头制定全球首个家用直流插头插座国际标准

Core Viewpoint - The recent establishment of two international standards for household and similar use DC plugs and sockets by China in the International Electrotechnical Commission (IEC) addresses a significant gap in international standards for this field [1][2] Group 1: Importance of Standards - The lack of unified international standards for household DC plugs and sockets has been a bottleneck for the broader and safer application of DC technology [1] - The new standards will define technical requirements and testing methods for safety, structure, mechanical performance, electrical performance, and dimensions [1] Group 2: Technological Advancements - The application potential of DC power supply systems is increasingly evident due to the rapid development of photovoltaic power generation, wind power, energy storage technologies, and various DC electronic appliances [1] - Compared to AC power, DC supply systems can effectively reduce energy conversion losses and enhance energy utilization efficiency in specific scenarios [1] Group 3: Collaborative Efforts - The two international standard proposals will be led by Chinese experts in collaboration with specialists from the UK, Germany, Italy, Jordan, Norway, and Belgium to ensure high-quality completion [2] - This collaboration aims to provide robust technical support for global green low-carbon transformation and sustainable development goals [2]
