资料介绍

针对低压配电系统可靠性的广泛需求,通过分析当前万能式断路器(ACB)智能脱扣器硬件系统的设计缺陷,提出一种以MSP430F149微控制器为核心控制单元的可靠性方案。该方案采用分割器和轨对轨放大器技术的电压信号调理电路,带微控制器监测的并联开关型稳压电源电路,以及低功耗技术设计,确保降低所有器件尤其是功率器件的温升,使ACB智能脱扣器的硬件系统设计更加简单,更符合电磁兼容特性和可靠性的理论指标。

In view of low voltage power distribution system for a wide range of needs,the current design defects of intelligent release hardware system for air circuit breaker(ACB) were analyzed,the reliable scheme for an MSP430F149 micro controller as the core control unit was s reliable scheme uses the splitter and the voltage signal processing circuit design of the rail-to-rail amplifier technology,and the parallel switch voltage-stabilized source circuit design with micro controller was used in the way of low power loss technical design to guarantee for reducing all component particularly power component's temperature makes the hardware system design of the ACB intelligent release simpler,conformable to the target of ...
