PURPOSE: A submerged discharging apparatus for water treatment is provided to maximize the life expectancy of a switch and facilitate the maintenance of the apparatus by using a self spark gap switch without a separate triggering unit. CONSTITUTION: A submerged discharging apparatus includes a pulse voltage unit(10), a water tank(11), a first electrode(12), a second electrode(13), a self spark gap switch(14), and a gas jet unit(16). The pulse voltage unit applies voltages to generate pulse based on the charging voltage of a capacitor. The first electrode and the second electrode face in the water tank. The self spark gap switch is converted into a conductive state in case of reaching a set voltage. The gas jet unit generates bubbles by discharging gas into water between the electrodes. Two power lines(17a, 17b) expanded form the pulse voltage unit are in connection with the first electrode and the self spark gap switch. Spark discharging is generated between the electrodes. |
