摘要：A water leakage detection device capable of detecting a rapid water leakage ina short time is provided. A water leakage detection device according to an embodiment isa water leakage detection device that detects a leakage of cooling water in a coolingsystem that cools a power converter, and sequentially detects a water level of a surge

tank that stores the cooling water. A data recording circuit for recording each time thewater level data is detected, a change amount calculating circuit for calculating a changeamount per unit time of the water level data recorded in the data recording circuit, andthe calculated change A change amount comparison circuit that compares the amountand a preset first determination value. When the change amount is greater than or equalto the first determination value, the change amount comparison circuit generates a firstalarm signal indicating that excessive water leakage has been detected.
