微型断路器是建筑电气终端配电装置引中使用最广泛的一种终端保护电 器。 微型断路器只是一种机械开关电器， 装置功能有限， 正常操作只能是手动 的。 不能满足配电系统信息化、 网络化、 智能化和多功能化程度不断提高的 要求， 开发一种多功能智能型微型断路器已是大势所趋， 也是微型断路器 的发展方向。
磁保持继电器是近几年发展起来的一种新型继电器， 也是一种自动开关。磁 保持继电器最早是主要用于 IC卡预付费电表、 集中抄表系统中。 磁保持继电器 虽然是一种自动开关， 但需要有控制电路配合才能实际使用， 而现有的磁保持继 电器尤其缺乏过载保护功能和完善的手自动一体的操作功能。
在物联网到来的时代， 智能家居逐渐走进普通百姓家庭， 亟需要发展性能可 靠、 结构简单、 制造简便、 成本低廉， 既满足普通百姓使用习惯， 又能提供智能 控制的家用微型断路器。
发明内容

本发明以高集成度的中央处理器 （STC1 1 F04E )、 计量芯片（CS5463- ISZ )和 485 ( SN75176 )芯片为核心， 通过配置相应的外围电路和电源构建智能磁保持微 型断路器的硬件电路系统。
与现有技术相比， 本发明采用微型断路器的外型标准， 通过将额定电流 80A 的磁保持继电器组件直接在智能磁保持微型断路器壳体内组装，不仅提高强电部 分与弱点部分的抗干扰能力， 而且有效节省了微型断路器壳体内的空间。 突破了 微型断路器机械开关的模式， 采用磁保持继电器技术替换机械开关， 通过壳体与 磁保持继电器的一体化融合设计， 留出空间用于电子部分的安装。
