一起10 kV电压二次空开跳闸的案例分析及启示

Case Analysis and Inspiration of a 10 kV Secondary Air Circuit-Breaker Triping

本文以一起10 kV电压二次空开跳闸的案例为切入点,阐明电压二次空开跳闸运行人员现场分析、故障查找、故障处理和电压二次寄生回路查找的措施和做法,从工程验收、设备启动、运行管理等各重要环节进行严格把关,保证电压回路正常,确保电网安全可靠运行。

Taking the case of a 10 kV secondary air circuit-breaker tripping as the entry point,this paper clarifies the measures about the on-site analysis,fault finding,fault handling and secondary parasitic loop seeking for the operators of voltage secondary air circuit-breaker tripping. All important aspects such as the engineering acceptance,equipment start-up and operation management are controlled strictly to ensure the normal voltage circuit and the safe and reliable operation of the power grid.
