RODENT ELIMINATION DEVICE-ELECTRIC DERATIZATOR Russian patent published in 1997 - IPC

FIELD: deratization of food and agricultural production storages. SUBSTANCE: electric deratizator has casing formed as packing device with load platform 1 and dielectric supports 2 and high-voltage electrodes 3 and 4 fixed at locations, that rodents will inevitably come into contact with. Electrodes are connected with electric power supply system having high-voltage pulse source 6 with high-voltage transformer and pulse generator provided with power condenser, controllable key, diode, charging resistor and power supply terminal. Electrodes 3 and 4 are connected to free lead of transformer secondary winding. Leading end of primary winding and point of connection between tail end of primary winding and leading end of secondary winding are connected through switch in two directions to output poles of pulse generator. Output terminals are connected to primary current source. Packing device has multiway or disposable pallet. High-voltage electrodes 3 and 4 are made linear and fixed in slots of load platform and along perimeter of platform and electrically connected one with another. Deratizator has second transformer allowing protective space to be increased, safety device and deratizator automatic switching system. EFFECT: increased efficiency in rodent control and enhanced reliability in operation. 6 cl, 4 dwg
