摘要
针对传统的电磁式重合闸装置存在动作级数多、触点粘连等不可靠因素,采用PLC实现自动重合闸,对其进行硬件设计和软件编程,所用元件极少,故障率大大降低,克服了电磁式重合闸控制方式的不足。控制柔性好,控制系统的供电可靠性高。
Aiming at the unreliable factors that the traditional electromagnetic ARD device has more action grades and adhering of contact, using PLC to realize the auto-reclosure and making the design for hardware and soft-ware, the used components is fewer, accident chance is much lower. The method overcomes the defects of the tra-ditional electromagnetic ARD control method. So control flexibility is strong and the reliability of power-supply of control system is high.
