This article is devoted to the problem of improving the operation reliability of electromechanical devices and devices at electric power industry facilities. Particular attention is paid to the fact that in the Russian power system electromechanical devices and devices designed for a voltage class of 110 kV and higher are still the majority compared to microprocessor and microelectronic devices. Given their long service life and the inability to promptly replace all devices at once, improving the reliability of their operation is highly relevant. A schematic solution to the problem is developed. The scientific novelty of the proposed solution is of the fact that the redundant power supply circuit with operating current of electromechanical devices offers a consolidated use of innovative electric power storage devices, namely ionistors and classic rechargeable batteries combined according to a special circuit. This solution maximizes the operation reliability of both electromechanical devices and devices themselves, as well as their automatic control.
