摘要
阐述500kV变电站内35kV站用变保护装置与控制电源的配置,在任何一路直流电源失电的情况下,存在站用变保护装置都无法跳开断路器的隐患,提出两种相应的改进措施。
This paper describes the configuration of the 35kV station transformer protection device and control power supply in a 500kV substation.In the event of any DC power loss,there is a hidden danger that the station transformer protection device cannot trip the circuit breaker.Two corresponding improvement measures are proposed.
