摘要： A purging device configured to purge a container defining a periphery of a pressurized explosion-proof structure by supplying protective gas into the container is provided. A purge controlling module controls a flow rate adjusting device to supply the protective gas into the container to purge during a purging period including at least two main periods and at least one sub period. The main period and the sub period are set alternately on a time axis. A maximum supply flow rate per unit time during the sub period is at or below 10% of a maximum supply flow rate per unit time during the last main period, and at or below 10% of a maximum supply flow rate per unit time during the next main period.
