一起220kV隔离开关控制失效的诊断与处理
Control Malfunction Diagnosis and Elimination of 220 kV Disconnect Switch
摘要
Abstract
To raise the technical level of professional technological personnel significantly and improve the operation level of power network, malfunction diagnosis and elimination of the 220 kV disconnecting switch are introduced, which happened in the Wulii transformer substation. The control fault phenomenon was briefly described. According to the circuit diagram, the cause was analyzed in detail and solved successfully, the reliability and security of power supply has been ensured. Through the analysis and research of the control fault, the corresponding operating experience was summarized to improve the capability and efficiency of operation and maintenance personnel when dealing with similar fault. The improvement scheme was put forward to enhance signal-sampling capability and fault diagnostic function of micro-computer protection device. The improvement strategies were presented to ensure the quality of power supply and help decrease the cost of the electric power production.关键词
