摘　　要：高频闭锁保护的发信和停信是保护能否正确动作的关键。高频闭锁保护发信回路相对简单,停信回路较复杂。介绍高频保护的位置停信、本线路保护跳闸停信、母差保护停信和失灵保护动作停信,以及弱馈保护功能的停信判据;总结了高频闭锁保护停信回路使用中应注意的问题。The signaling-transmit and signaling-stop of high frequency blocking protection is the main factor to determining the proper action of the protection. The signaling-transmit circuit of high frequency blocking protection is comparatively simpler than signaling-stop circuit. The signaling-stop criterions of high frequency protection position signaling-stop, lines protection trip signaling-stop, busbar differential protection signaling-stop, failure protection operation signaling-stop and weak-infeed protection function have been presented. The problems should be noticed bin high frequency protection signaling-stop circuit have been summarized.
