method of disconnection in the network with isolated neutral voltage up to 1000 in the u044du043au0441u043au0430u0432u0430u0442u043eu0440u0430u0445

摘要

the invention relates to electrical engineering and can be used in the devices of power in electric networks with isolated neutral.the technical result of the invention is to increase the efficiency of the devices in the network with isolated neutral voltage up to 1000 in the ec u0441u043au0430u0432u0430u0442u043eu0440u0430u0445,based on the case of food, in the event of a malfunction isolation on land by increasing the capacity of phases relative to the earth.the developed method of disconnection in the network with isolated neutral voltage up to 1000 in an excavator based on the imposition of a dc to u0442u0440u0435u0445u0444u0430u0437u043du0443 yu network with fixed u0443u0441u0442u0430u0432u043au043eu0439 u0441u0440u0430u0431u0430u0442u044bu0432u0430u043du0438u044f protection from damage to the isolation of a phase to earth through the three-phase power network by increasing the capacity of phases relative to the earth.
