The 60OOkW high-voltage variable frequency power supply test device developed by Suzhou Huadian for Guangzhou Siemens Transformer Co., Ltd. successfully carried out the no-load and load tests for the factory inspection of UHV converter transformers and the on-load sub-switch switching operation tests.
At the same time, it can meet the no-load, load and temperature rise tests of 50OkV single-phase and three-phase integrated transformers
In January 2019, the 50000kW high-voltage variable frequency power supply complete test system customized by Suzhou Huadian for the State Grid Qinghai Electric Power Research Institute was successfully applied to the Qinghai Maintenance Center of the State Grid ±80OkV converter transformer
