直流电器标准研究

Research on the standard of DC appliances

随着低压直流技术的快速发展,“光储直柔”成为民用建筑领域实现碳中和的重要路径,直流电器的规模化应用将成为“光储直柔”的重要支撑,而直流电器在实现产品化的过程中,不仅要解决关键技术问题,还需要同步构建设计标准和评价体系。分析了交流供用电向直流供用电转换对家用电器设计和评测带来的问题,吸取家电行业标准框架体系经验,分析了标准框架下的条款适应性,列举关键技术指标修订方案,重点探讨了直流电器标准的意义和挑战,并对直流电器体系标准的构建提出了建议。

With the rapid development of low-voltage DC technology,"Photovoltaic,Energy storage,Direct current and Flexibility(PEDF)"has become an important path to achieve carbon neutrality in the field of civil buildings.The large-scale application of DC appliances will become an important support for PEDF.In the process of realizing the commercialization of DC appliances,it is not only necessary to solve key technical problems,but also need to synchronously build design standards and evaluation systems.Analyzes the problems caused by the conversion of AC power supply to DC power supply to the design and evaluation of household appliances,draws on the experience of the standard framework system of the household appliances industry,analyzes the adaptability of the terms under the standard framework,lists the revision scheme of key technical indicators,focuses on the discussion of the significance and challenges of the DC appliance standard,and puts forward suggestions for the construction of the DC applian ce system standard.
