摘要
介绍了大机组整套启动前进行主变压器带高厂变受电冲击试验的方法、过程以及注意事项。进行该项试验能够提前完成大型变压器的冲击试验考核并对相关二次回路、保护装置进行带电检查,对厂用电高压电源进行核相及厂用电切换试验试验工作,能大大缩短机组整套启动电气试验时间。
Introduced the method of large unit, set to start before the main transformer by electric shock test with HV auxiliary transformer process and matters needing attention. Impact test of the test can be completed in advance of large transformers and secondary circuit, protection device for electrical inspection of power plant, the high-voltage power supply for n phase inspection and auxiliary power switching test work, can greatly shorten the unit set to start electrical test time.
