摘　　要：在通信基站等特殊用电场合,其供电电路往往不止一路,因此选择普通单相或者三相电表并不能满足其计量和上报需求。针对此类需求,某些公司也设计了多回路电表,但在实际使用中,由于电表的回路数量出厂时已经确定,其灵活性和扩展性也不高。因此通过分析现有的解决方案,探讨出一种设计方法,其主要特征是采用管理模块和多个计量模块组合的方式,支持计量模组的自由扩充,并且计量模组在实际安装时可以独立使用,利于分布式实施,尤其适用于基站等供电环境复杂的场合。Multi power supply is usually used in special occasions such as communication base stations,therefore neither single-phase nor three-phase electric meter meets its metering and reporting requirements.Aiming at the demand,some companies have designed multi-loop electrical meters.However,in practical applications,the flexibility and scalability are limited for the number of loops in the meter has been determined at the factory.We will explore a design method based on the analysis of existing solutions,the main feature of which is the combination of management module and multiple metering modules,free expansion of metering modules supported,and the metering module used independently during actual installation.It is conducive to distributed implementation,especially suitable for complicated power supply occasions such as base stations.
