摘要
详细分析了双母线带旁路接线方式下,因母线保护在传动断路器时,由操作箱TJR接点经第二套线路纵联保护通道远跳线路对侧,分析了导致断路器事故跳闸的原因。通过分析提出了停用纵联保护通道的观点,从而保证了继电保护可靠性和电网的安全运行。
For double-bus lines with bypass, when the bus protection is turnung the circuit breaker, the opera tion box TJR connects through the second line longitudinal protection channel with the opposite side tele-trip- ping circuit. This paper analyzes the cause of circuit breaker tripping accident. Through the analysis, it sug gests terminating the longitudinal protection channel in order to guarantee the reliability of relay protection and the safe operation of the power grid.
