摘要： A lightning arrester comprises nonlinear resistance discs 2 stacked within a ceramic casing 1, with annular metal cover rings 3, 4 being fixed to the opposite outer ends of the casing. Conductive plates 5, 19 having reduced thickness rupturable central portions are sealed to the inner ends of the casing, with the lower plate 19 being insulated from the lower ring 4 by an insulating ring 20. An ammeter 16 is connected between the conductive plate 19 and ground by a lead wire 21 passing through the ring skirt but insulated therefrom, whereby only leakage current passing through the nonlinear resistance discs is sensed.

摘要： A power converter adapted for use in a high-voltage circuit and equipped with a plurality of arms each comprising a plurality of thyristor elements connected in series, wherein an overvoltage limiter having an overvoltage limiting element and means for short-circuiting the ends of the overvoltage limiting element in response to flow of a load current therein are connected between the anode and the cathode of each thyristor element. The short-circuiting means has a gap between the two electrodes connected respectively to the anode and the cathode of each thyristor element, and also a metal layer of a low melting point which is molten by heat generated due to the flow of a load current in the overvoltage limiting element to fill the gap.
