摘要
针对330kV朱家变8.19事故为例:开关机构箱进水造成加热器短路,致使交流电压串入直流系统导致两台330kV系统变压器开关跳闸。分析其原因并提出改进措施,确保电力系统供用电设备在良好环境下安全、稳定、可靠运行。
For 330 kv Zhujiabian accident, short circuit caused by switch box water heater, which makes ac voltage in series with de systems. Thus, two 330 kv transformer switches trip. Analyzing the causes and putting forward the improvement measures ensures power supply equipment of power system to run in a good, stable and reliable environment.
