摘要
针对某电厂高压厂变分支速断保护动作引起发电机跳闸事故,根据保护装置故障记录和故障录波器数据,分析保护动作情况,查找出故障原因,提出了改进建议。
To deal with the tripping accident of the generator caused by branch instantaneous overcurrent protection action for high voltage auxiliary transformer,this paper analyzes the protection action according to the fault record of protection and data of recorder to indentify the fault causes,which offering proposition on improvement.
