摘要
用于检测避雷器阀片的直流高压恒流源，采用带反馈控制系统的交流－直流－交流变换，使输出的直流高压从３ｋＶ到８ｋＶ 连续可调，以自动保持通过不同被测阀片的电流为１ｍ Ａ。
A HVDC constant current source for testing arrester varistor is developed. The DC output voltage of the source can be continuously changed from 3kV to 8kV by means of feedback control and AC DC AC conversion. With the varying DC voltage, the current through the different tested varistor is automatically kept at a value of 1mA.
