机电式控制电路电器新旧标准的差异研究

Study on Differences Between New and Old Standards of Electromechanical Control Circuit Devices

介绍了机电式控制电路电器的用途、使用类别及其标准的适用范围,针对控制电路电器新旧产品标准的差异变化问题,详细分析了新旧标准中在 EMC、接线端子性能、规范性附录、产品特性、材料性能等方面的差异,给相关技术人员提供一定的参考。通过对比发现,新标准无论在试验要求上还是在对试验结果的评判上都更加接近了低压电器往智能、安全、健康方向发展的趋势。

Introduction was made to usages,utilization categories and standard applicable scope of electromechanical control circuit devices.Aiming at the differences and changes between new and old product standards of control circuit devices,this paper detailedly analyzed the differences between new and old standards,such as electro magnetic compatibility(EMC),terminal characteristic,normative appendix,product features and material property etc,which provide certain references for the related technical personnel.After comparison,it is founded that whether the testing requirement of new standard or the judgment of testing results will make the low-voltage development trend close to the direction of intelligence,safety and health.
