在500 kV开关传动试验验收过程中,发现同塔双回输电线路自适应重合闸开关液压机构控制回路与常规重合闸开关控制回路设计相同,自适应重合闸功能将无法实现,这给电力系统的稳定、可靠运行带来极大的安全隐患。通过对自适应重合闸动作过程及液压机构控制回路的分析,提出了具体的解决方案和防范措施。
在500 kV開關傳動試驗驗收過程中,髮現同塔雙迴輸電線路自適應重閤閘開關液壓機構控製迴路與常規重閤閘開關控製迴路設計相同,自適應重閤閘功能將無法實現,這給電力繫統的穩定、可靠運行帶來極大的安全隱患。通過對自適應重閤閘動作過程及液壓機構控製迴路的分析,提齣瞭具體的解決方案和防範措施。

During the acceptance of 500 kV switch driving test , it is found that the control circuit of hydraulic unit in self -a-daptive reclosing switch is the same as the control circuit of the general reclosing switch in double -circuit lines on the same tower, so the function of self-adaptive reclosing cannot be achieved , which brings a great security risk to the stable and relia-ble operation of power system .Though analyzing the action process of self -adaptive reclosing and the control circuit of hy-draulic unit , the specific solutions and preventive measures are proposed .
