In addition, the leakage alarm system further includes: a battery; a relay switching charging or discharging of the battery; and a leakage detector switching the relay so that the battery is charged through the power line buried in the manhole when the manhole leakage is not detected, and switching to provide battery DC power charged in the battery to the leakage alarm and the controller when the manhole leakage is detected.
