摘要
特高压换流站电压等级高、输送容量大、控制策略复杂,因此二次控制柜的运行状况对于保障电网安全运行十分重要。对4台带电状态下特高压输电工程二次设备控制保护柜进行振动台试验,输入抗震设防烈度为9度的人工地震波,检验其抗震性能。试验结果显示保护柜在试验过程中没有结构和电气功能上的损伤,达到抗震要求。
As high voltage level,large transmission capacity and sophisticated control strategy in UHV converter station,stability of control cabinet should be significant for safe operation of power grid.4 live cabinet for UHV transmission project were tested on shaking table with the input of artificial seismic wave at 9 degree intensity to test their anti-seismic performance.The test results show that the objects satisfied the anti-seismic requirements without structural and electrical damage in the test.
