1接点抖动的分析在变电站自动化系统中,一次设备的位置信号量采集是取自这些设备的位置信号接点或者辅助接点。一次设备的机构在操作一定次数后,其接点的机械部分会产生缝隙;继电器接点的动作机构由于反复动作,其机械强度出现下降,动作后接点会发生震动;同时,信号回路中 Analysis of Jitter Junction In substation automation systems, the primary signal acquisition of a device is taken from the position signal contacts or auxiliary contacts of these devices. Once a certain device is operated for a certain number of times, the mechanical part of the contact will have a gap; the mechanical strength of the relay contact action mechanism will decrease due to repeated actions, and the contact will vibrate after the action; at the same time,
