A DEVICE FOR RIDDING OF RODENTS: AN ELECTRICAL DERATIZATOR

摘要

The device for eliminating rodents in the form of an electrical anti-rat device comprises a body made from a dielectric material and made as a packaging means with a load platform (1) and supports (2), provided with high-voltage electrodes (3 and 4) secured on the packaging means in the place where the rodent will inevitably touch them and connected to a power supply system, wherein a source of high-voltage pulses (6) is made as a high-voltage transformer (10) and a pulse generator (10), comprising a power capacitor (14), a controlled electronic key (13), a diode (18), a charging resistor (19), and power supply terminals. The electrodes (3 and 4) are coupled to the free terminal (11) of the transformer secondary, the beginning of the transformer secondary and the point of connection of the end of the transformer primary and the beginning of the transformer secondary are coupled through a two-way contactor (27) to the output terminals (12 and 17) of the pulse generator, the input terminals (15 and 16) thereof are coupled to the primary power supply source. The power supply system is provided with a control unit (7). The packaging means is made as a returnable or expendable pallet, the load platform (1) rests on the floor through non-metallic supports (2), and the contact electrodes (3 and 4) are made linear, arranged in grooves provided in the load platform and along the periphery of the packaging means, and galvanically interconnected. The device has a quick-disconnect electrical contact (5) for coupling to the power supply system. The device is provided with a non-contact detector (9) adapted to detect rodents and with a safety system (8) for servicing personnel. The device is provided with a contactor for automatic setting thereof which is activated as soon as the lighting in the premises is switched off. For increasing the scope of protection, the device is provided with a second high-voltage transformer (40).
