とする避雷器の動作責務試験装置。[Claims for Utility Model Registration] An AC voltage is applied to the lightning arrester under test by an AC voltage application circuit, and by short-circuiting the starting gap in synchronization with the AC voltage, an impulse current is applied to the lightning arrester by the lightning impulse circuit. In the supplied lightning arrester operating duty testing device, the lightning impulse circuit is connected in series to a lightning impulse generation section consisting of a series circuit of a capacitor and a resistor and a charging section for charging this capacitor, and to this lightning impulse generation section. The starting gap is connected in series with this starting gap, and when the starting gap is short-circuited, it is made conductive by the charging voltage of the capacitor, causing an impulse current to flow through the arrester under test, and after the impulse current flows, it becomes insulated and becomes an AC voltage. a gear press arrester for separating the application circuit and the lightning impulse circuit; and a gear press arrester connected between both ends of the lightning impulse generator so as to discharge the charge remaining in the capacitor after the gear press arrester becomes insulated. A lightning arrester comprising a discharge resistor and a voltage sharing resistor connected between a mutual connection point of the gear press arrester and the starting gap and one end of the lightning impulse generating part so as to share the voltage of the gear press arrester and the starting gap. Operational liability test equipment.
