摘　　要：智能型量测开关是将电度表计量功能与智能塑壳断路器“合二为一”的一种智能电器,它用高端带谐波分析的计量芯片和M4核CPU组合成一个高精度计量与具有“长延时反时限保护、短延时定时限保护、瞬时保护的塑壳断路器”组合成一个整体,实现高精度电能计量、三段保护的智能电器。Intelligent measuring switch is a kind of intelligent electrical appliance that combines the measuring function of watt-hour meter with intelligent molded case circuit breaker(MCCB).It uses high-end measuring chip with harmonic analysis and Cortex-M4 CPU to form a high-precision measuring device,and combines it with molded case circuit breaker with long delay inverse time protection,short delay fixed time protection and instantaneous protection to realize high-precision electric energy measurement and three-stage protection.

关 键 词：电度计量 三段保护 量测开关 谐波分析
