FIELD: electricity.
SUBSTANCE: electric fish barrier includes an electronic control unit (1) and a single-row system of electrodes (2) divided into sections. Each electrode (2) is divided along a vertical line into elements (3) with the help of insulators (4). Sections of electrodes (2) are made of stiff electrodes. Electrodes (2) are made in the form of pipes, bars or flexible electrodes. Flexible electrodes may look like soft bare cables or a chain with a bare strand pulled through chain links, or a chain with a copper tinned mat placed on it. Pulse current from the supply unit (1) is supplied to each separate element of the electrode (2) with the help of a supply cable (5). It is possible to supply voltage of different potential to separate elements of the electrode (2) at different depths.
EFFECT: creation of more even structure of electric field and possibility to adjust intensity of electric field along depth.
