摘　　要：针对断路器智能保护的特点,笔者主要进行了断路器智能综合控制装置关键技术的研究。搭建了系统的软硬件平台。重点介绍了基于耐热量降低原理的反时限保护及切断终端故障用户的分界开关功能,并对技术要点和难点进行解释说明。此外,对提高配电系统供电可靠性的方法理论进行介绍,利用开合断路器时序的变化,完成故障用户隔离闭锁、非故障区段正常供电。利用液晶屏幕实现故障信息现场查看,通过USB接口及工业RS485总线通讯接口搭载Modbus协议实现与其他保护装置及上位机之间通讯,此外还利用GSM通信模块实现超远距离控制分合闸及故障信息及时反馈,实现信息网络化,为智能化电网提供设备支持。Key technologies for intelligent integrated controller of circuit breaker are studied with regard to the characteristics of intelligent protection of circuit breaker. Focuses are laid on the inverse-time protection based on the principle of thermal resistance reduction and the boundary switch function for cutting off the terminal user in fault, and the relative techniques are discussed in detail. The theory of enhancing reliability of power distribution is introduced. Therefore, isolation of the user in fault and resumption of normal power supply in the non-fault section are realized by making use of temporal variation of opening and closing circuit breaker. The controller communicates with other protection devices or PCs through USB interface or industrial RS485 bus communication interface with protocol Modbus. In addition, GSM communication modules are used for ultra-remote control of opening and closing switch and timely feedback of fault information. The intelligent integrated controller of circuit breaker may provide a support to information networking and intelligent grid.
