摘要：

PROBLEM TO BE SOLVED: To provide a gas circuit breaker which decides about voltage abnormality, after confirming battery capacity and a voltage with a battery capacity estimating means, if battery voltage reduction is

detected.;SOLUTION: The gas shutoff device is constituted, such that the supply voltage of a battery power source means 2 is monitored with a voltage detecting means 10; estimation calculation of the amount of consumption of the battery is performed previously, with a battery capacity estimating means 11, from the driving number of a shutoff means 3 and time elapsed from the start of power source supply, if a signal of or smaller than a predetermined voltage is detected with a voltage detection means, even if the estimated amount of consumption is determined, with the battery capacity estimating means 11, to be within a predetermined range; the voltage detection means 10 is again driven to confirm the voltage of the battery power

摘要附图：

source means 2 again, if a normal voltage is detected, a voltage reduction signal is not outputted; the voltage detection means 10 is again driven to confirm the battery voltage; and the gas shutoff device comprises a time measuring means 13, which starts to measure concerning predetermined time, if a

voltage reduction state is detected with a voltage abnormality deciding means 12, a return means 14 which outputs a signal for returning the shutoff means 3 to a gas supply enabled state, and a return

電源を供給する電池電源手段と、ガス媒体の供給や遮断を行う遮断手段と、前記電池電源手段の供給電圧を監視し電池電圧を検出する電圧検出手段と、前記遮断手段の駆動回数及び電源供給開始からの経過時間より電池消費
