According toThe test procedures for the withstand voltage of electrical equipment in substation with voltage levels of 220V and below require that the corresponding AC/DC withstand test equipment must meet both high-voltage, low-current test conditions and low-voltage, high-current test conditions. It is necessary to accommodate a wide range of applications. The series resonance withstand test device is composed of a variable frequency power supply control box (console), an excitation transformer, a reactor, and a capacitor voltage divider, utilizing the series resonance principle. By connecting a rectifier silicon stack and a microammeter to the capacitor voltage divider, a DC withstand test can be completed. Due to the excellent filtering characteristics of the system after resonance, the produced DC voltage is superior to that obtained from a common test transformer rectifier. It is the ideal AC withstand test equipment for local, municipal, and county-level high-voltage test departments, as well as for power installation, maintenance, and testing engineering units.
