摘要

the invention u043eu0442u043du043eu0441u0438u0442u0441u00a0 to electrical engineering. the purpose of improving the reliability of the electric u0438u0437u043eu0431u0440u0435u0442u0435u043du0438u00a0 - by u0438u0441u043au043bu044eu0447u0435u043du0438u00a0 multiple repeat stopping regimes.the device, developed a way, in the initial time of starting is by block 11 u0443u043fu0440u0430u0432u043bu0435u043du0438u00a0 and u043fu0435u0440u0435u043au043bu044eu0447u0430u0442u0435u043bu00a0 13 input element 15 u0441u0440u0430u0432u043du0435u043du0438u00a0 source 12 u043eu043fu043eu0440u043du044b x signals than u0443u0441u0442u0430u043du0430u0432u043bu0438u0432u0430u0435u0442u0441u00a0 assignment by current and start of ignition to the cut-off frequency is in constant value of current u0434u0432u0438u0433u0430u0442u0435u043bu00a0 (d) 1.when the overload current u0434u0432u0438u0433u0430u0442u0435u043bu00a0 u04341 with current sensor 4 exceeds the maximum allowable value, the desired block 12. the signal at the output of the element 14 u0441u0440u0430u0432u043du0435u043du0438u00a0 and u043fu043e10 with u n o eat n3 th
