FIELD: electricity.SUBSTANCE: electric pulse de-icing device contains a number of inductor modules, each contains an accumulative capacitor, a controlled key, a protective diode, a volt sensitive circuit with the control impulse generator and the inductor located near the de-iced metal surface. The input of the inductor module is connected to the input of the accumulating capacitor, and the output through the controlled key is connected to the inductor parallel to which the protective diode is connected. The volt sensitive circuit with the control impulse generator is connected to terminals of the controlled key. There is a control unit of inductor modules the input of which through the switch is connected to a power line, and outputs - to inputs of the inductor modules. The control unit of inductor modules comprises a power supply, a logical control system, switching keys, a charger and a voltage rectifier. Inputs of the voltage rectifier and the power supply are connected to the input of the control unit of inductor modules. The voltage rectifier output through the charger and switching keys is connected to the outputs of the control unit of inductor modules.EFFECT: invention is aimed at improvement of operation reliability and safety.2 cl, 3 dwg |
