摘要（英）：

The invention discloses a transient test device for a high-voltage DC voltage transformer, which comprises a high-voltage DC charging power source, a DC square wave generator, a high-voltage standarddevice, a voltage transformer, a transformer transient calibrator, a PC end, etc. Therefore, the transient test of the voltage transformer is realized by the high-voltage DC charging power source or the like; moreover, the DC square wave generator includes a plurality of charging and discharging units connected in parallel and a relay switch assembly for controlling the working state of the charging and discharging unit; and thus, through changing the number of the charging and discharging units, the magnitude of the high voltage outputted by the DC square wave generator can be adjusted so asto meet the transient test requirements of the voltage transformers of different voltage levels.
