摘　　要：为了保证断路器保护功能稳定可靠,本文将保护模块和管理模块相互独立,设计了“保护芯+管理芯”的双芯低压智能断路器方案。本文对保护芯、管理芯、电源和信号采样四个模块的硬件关键技术和保护软件、管理软件的设计进行介绍,并通过试验对测量精度进行测试。保护采样和测量采样相互独立,保护芯模块通过自生电源可满足自身独立供电需求,保证保护芯模块脱离管理芯模块后能够独立工作。该设计可使断路器的断路保护部分与管理监控部分分离,提高断路器保护功能的稳定性和可靠性。In order to ensure the circuit breaker protection function is stable and reliable,the protection and management are modularized into two independent parts,and a dual-core low voltage intelligent circuit breaker scheme of“protection core and management core”is designed in this paper.The architecture of protection core,management core,power supply and signal sampling module,the architecture of protection software and management software are introduced.The measurement accuracy is tested by experiment.The protection transformer and the measurement transformer are independent of each other,and the protection core can realize its own independent power supply through the self-produced power supply.This ensures that the protection core can work independently from the management core.The design can isolate the protection part and the management part of the circuit breaker,and improve the stability and reliability of circuit breaker protection function.
