Beschreibung
Zusammenfassung:	Disclosed is a variable-frequency series resonance voltage withstanding test device. With the development of electric power cause, capacitance of all of long-distance cable lines, power transformers and large-sized generator sets is high. The variable-frequency series resonance voltage withstanding test device structurally comprises a variable-frequency power source (1) connected with an exciting transformer (2), a lightning arrester (3) is parallelly connected with the exciting transformer and a series circuit of a resonance reactor (4) and a voltage divider (5), and the voltage divider is provided with an end parallelly connected with a sample (6). The variable-frequency series resonance voltage withstanding test device is used for resonance voltage withstanding tests.
