The series variable frequency resonant device is a common primary electrical equipment of substations. It is applied for voltage withstand test of capacitive equipment, such as transformer, GIS system, SF6 switch, CT/PT, insulator, busbar, cable and bushing ect. This device is researched and manufactured according to withstand test regulations of 220KV and blow substations primary electrical equipment. The AC/DC voltage withstand test equipment both need satisfy high voltage, small current and low voltage, large current test condition, and with wide application range. The using the principle of series resonant, is composed by variable frequency power source control box(console), excitation transformer, reactor and capacitive voltage divider,compensating capacitor.
