Embodiment Construction
[0009] The present invention is implemented in Shendai Reservoir, Mianyang City, Sichuan Province. The installation method is hanging type, and the installation position (water area cross section) is 165 meters × 15 meters. There are 77 electrodes arranged in the grid. The electric intensity field at 3 meters on the side of the electrode array facing the water is 20v / m, and the water flow velocity at the grid electrode array is 0.03.5m / s. Three pulse machines are used in parallel to supply power. The output voltage of each pulse machine is 1170 volts, current It is 3000 amps, and the pulse frequency is selected as 20, 38, 50HZ respectively.
[0010] Practice has shown that the power grid can intercept 60%-80% of whitebait over 3cm, and the use effect is good.
