FIELD: agriculture and food-processing industry, in particular, rodent control in storages. SUBSTANCE: device has housing formed as packing unit with load platform 1 and supports 2 made from dielectric material and high-voltage contact electrodes 3 and 4 fixed on housing in locations, where rodents will inevitably appear and come in contact with them. Contact electrodes are connected with power supply system having high-voltage pulse source 6 formed as high-voltage transformer 10 and pulse generator. The latter has power capacitor 14, controlled switch 13, diode 18, charging resistor 19 and supply terminals. Contact electrodes are connected to free lead of secondary winding of transformer. Leading portion of transformer primary winding and connection point of tail end of primary winding and leading end of secondary winding are connected through switch in two directions 27 to output poles 12 and 17 of pulse generator and output terminals 15 and 16 are connected to primary power source. Packing unit is formed as multiway or disposable tray. High-voltage contact electrodes 3 and 4 are made linear and fixed in load-receiving slots of platform along perimeter and electrically connected one with another. Device has second transformer 40, safety unit and system for automatic switching of deratizator. EFFECT: increased efficiency, improved safety and enhanced reliability in operation. 2 cl |
