摘要: 为实现对微型断路器误动作的弥补,本文设计了一种与微型断路器配套使用的电动操作系统.该设计属于机电一体化产品,测试标准对标欧盟家用电器、电动工具或类似器具的电磁兼容标准EN55014.本文重点关注其中4类指标:发射干扰EMI(Electron-Magnetic Interference),抗干扰性EMS(Electron-Magnetic Susceptibility),谐波干扰Harmonic,电压扰动Flicker.通过设计高集成、谐波强衰减、高抗浪涌能力的低通滤波器,采用准谐振软开关技术及分时变频的控制策略,优化的PCB(Printed Circuit Board)布局布线,实现对电磁兼容性的优化,并在第三方检测机构测试通过,获得CE认证.

Abstract: An electric operation system matched with the miniature circuit breaker is designed in order to compensate for the mis-operation of miniature circuit breaker.The breaker is a kind of mechatronic products and European Union EMC standard EN55014 is required.For the design in the paper,four characteristics are mostly concerned:EMI,EMS,Harmonic and Flicker.The strategies in the design include three aspects.The first one is using the low-pass filter with high integration,strong harmonic attenuation and high surge resistance.The second one is the quasi resonant soft switch technology and time-sharing frequency conversion control strategy.The third one is optimizing the PCB layout and the wiring.Finally,the designed breaker reaches the critical standards and obtains the qualified CE certification.

Key words: miniature circuit breaker, electron-magnetic compatibility, integrated low pass filter, quasi-resonance
