摘要
通过对继电保护及自动装置远方控制问题的分析,提出利用远方控制高压电气设备的原理,将电触发命令转换成位置状态变换、用机械闭锁方式实现自保持功能,实现远方投退继电保护及自动装置压板回路的解决方案。针对现场具体情况进行了"一对一"、"一对多"实例分析。
Based on the analysis on the remote control of relay protection and automatic device,a scheme for realizing remote switching-on and switching-off of relay protection and automatic device strap circuit is proposed using high voltage equipment remote control principle.In this scheme,electric impulse is transformed into position state shifting,and the condition self-holding function is realized in a mechanical interlocking manner.The one-to-one and one-to-many instances are analyzed according to the field conditions.
