Design of Smart Quick Disconnect Switch System Based on SCM320
Due to the limitation of working mechanism and principle,the traditional drop fuse has some inherent defects,which affect the fault isolation of distribution network to a certain extent.In order to overcome such defects,further reduce the fault interval,improve the success rate of line reclosing and reduce the occurrence of customer outage,a new type of distribution network switch system with adjustable parameters is proposed in combination with the requirements of current distribution network development.The system is based on SCM320 single chip microcomputer,adopts redundant design and consists of multiple modules,so as to realize quick and intelligent disconnect function.Based on the hardware and software design,the ignition driving signal,insulation and disconnection experiments are carried out.The results show that the system is feasible in smart distribution network switchgear,and it is helpful to improve the reliability of power supply,which has certain reference and application value for the construction and development of smart grid.
