    1 功能与技术要求 1.1 规格要求 准确度等级：有功 A 级。 参比电压：220V。 参比电流：0.25-0.5(80)A（Ist=0.02A）。 参比频率：50Hz。 表 1 规格要求与推荐常数 智能电能表种类名 准确度等级 接入电路 称 方式 电流规格 电压规格 推荐常数 A 级单相多芯模 组化智能电能表 有功 A 级、基波 2 级，谐波 5 级 直接接入 0.25-0.5(80)A 220V 1200imp/kWh 电能表具备三个模块接口，定义详见 1.4 模块接口。上行模块具备强电接口，主要用于 上行载波通信，当通过载波与智能家居等设备进行下行通信，该模块是一个上下行功能复用 模块。 具有两个扩展模块，其尺寸和硬件接口统一，可互换安装，扩展模块根据应用需求选配， 可能是非介入式负荷感知模块、多表集抄模块、有序充电模块等。 1.2 功能划分 计量芯和管理芯采用物理分离原则，计量芯是高可靠性、长寿命法定部分，不允许进行 软件升级。 计量芯提供电量、时钟等法制数据，每分钟保存正反向有功总电能、每 15 分钟保存正 反有功基波电能、正反有功谐波总电能等历史数据用于电量追溯。管理芯的电量、时钟以计 量芯为基准，并实时同步。 计量芯能记录管理芯插拔、掉电、电表清零、校时、管理芯升级、开盖等事件记录。 计量芯允许电表清零、修改时间，存储通信地址、误差在线监测等参数，通信地址以计 量芯为准，其它参数可通过管理芯同步。 1
    计量芯和管理芯之间采用明文数据交互，未来可能采取身份认证的方式进行认证。 管理芯承担整表的管理任务，主要包括费控、显示、对外通信、事件记录、数据冻结、 负荷控制等任务，支持软件升级。管理芯不支持所有和费率相关的内容，包括费率电能、时 段方面参数。管理芯具备过载跳闸、端子过热跳闸功能，并可配置是否启用，默认不启用， 过载恢复合闸、端子过热恢复合闸由管理芯给负荷开关发合闸允许命令。已处于拉闸状态的 电能表在接收到保电命令后，电能表液晶“拉闸”字样消失。收到保电命令时通过蓝牙通道 向外置断路器发送“合闸允许”命令。 管理芯取消本地费控功能，负荷开关采用外置方式，至少具备蓝牙和上行模块两路对外 通信接口，同时保留两路扩展模块接口，根据应用需求选配，单个模块的电源故障或通信线 路故障不能影响其它模块正常工作。 原跳闸命令用于主站对电能表、终端执行，原命令中有继电器序号，告警延时，限电时 间，自动合闸；合闸命令中有合闸允许/直接合闸选项，这些功能费控逻辑部分在电表内部 执行，电能表对蓝牙断路器发出跳合闸及合闸允许命令。 电表清零仅限测试密钥状态下进行，管理芯、计量芯电表清零分两条命令，分别采用逻 辑 00、01，清零顺序为先清零计量芯，后清零管理芯，电能表返回的逻辑地址和主站下发 的逻辑地址一致。 如果需要清零扩展模块，采用扩展模块逻辑地址发清零命令。 校时逻辑地址采用 01，管理芯收到后转发给计量芯，计量芯完成校时，管理芯时钟同 步后，管理芯给模块发设置时钟命令。 逻辑地址 00 表示管理芯，01 表示计量芯，对于其它模块，采用扩展逻辑地址表示，电 表中扩展电能表模组列表，电能表模组列表中包括扩展模块及其对应的扩展逻辑地址。考虑 安全方案解密需要，主站（含终端）和计量芯通信时采用逻辑地址 01，管理芯和计量芯通 信时采用逻辑地址 00。管理芯和各个模块数据交互时带逻辑地址。计量芯和模块收到报文 时不判断报文中逻辑地址，计量芯和模块应答报文中的逻辑地址同接收报文。 主站抄读计量芯数据，无论建立不建立应用连接，如果需要加解密，都按《多芯模组化 智能电能表计量芯安全芯片产品手册》中用“读取（抄读计量数据）”的指令流加解密。 电表支持采用公共连接、一般密码建立应用连接，一般密码默认“00000000”。 电能表产品的设计和元器件选用应保证产品使用寿命大于等于 15 年。 详细的功能定义见附录 A：功能列表。 2
    法制相关软件： 在仪表中实现以下功能的软件应被认为是法制相关软件： （1）电参数的测量（如：电压、电流、有功功率、无功功率、频率）； （2）电能量的计量（如：有功电能，无功电能）； （3）时钟或时钟的维持； （4）设备专有参数的保护； （5）电参数、电能量数据的冻结； （6）清零、升级、校时、修改设备专有参数的事件记录； （7）法制相关软件与非法制相关软件的软件接口； （8）保证法制相关功能安全性的方法； （9）法制相关软件的标识； （10）法制相关内容的显示。 非法制相关软件： 实现以下功能的软件可以被认为是非法制相关软件： （1）显示方式以及非法制相关内容的显示； （2）除法制相关功能外的事件记录； （3）外部数据通信接口的实现（如红外、RS485、载波、无线等）； （4）控制功能（如对负荷开关的控制）； （5）报警功能； （6）其他未被提及的功能。 1.3 外观 1.3.1 外型尺寸 整表尺寸与现在国网表尺寸一致，160 mm（高）*112 mm（宽）*71 mm（厚），同时 取消弱电辅助端子。 1.3.2 管理芯模块接口 管理芯模组由管理芯 MCU、蓝牙、液晶等部件组成，支持热插拔，可采用插座插针方 3
