FIELD: electrical engineering. ^ SUBSTANCE: present invention relates to electrical power distribution systems of aircraft, and more specifically to electronic circuits of switching electrical power lines to users. The method is based on controlling, using an actuating element on linear laws preventing deviation of supply voltage from a given value, in aircraft electrical power supply systems when loads are connected or disconnected from power distribution systems. The control device used in the device for switching and protecting electrical power lines to users is a decoder, and the device for generating the control signal is based on a generator of linearly varying voltage. The electrical circuit comprises an actuating element, a detecting element, comparator, differential-functional amplifier, voltage switch, differentiator and a multiplex link microcontroller. ^ EFFECT: improved quality of electrical energy. ^ 2 cl, 1 dwg, 1 tbl |
