摘要
针对影响变压器差动保护正常工作的突出问题 ,分析并利用间断角原理判别变压器中的励磁涌流和内部故障电流 ,采用 80C1 96KC单片机和双端口存储器等数字电路 。
Aiming at the problems of influencing the normal operation of the differential protection device for transformers, the magnetizing inrush current and internal fault current are analyzed and identified by using the principle of dead angle. A single chip microcomputer 80C196KC and double terminal ports memory etc. digital devices are adopted to carry out the microcomputer differential protection with magnetizing inrush current latching for transformers.
