摘要

the invention relates to electrical engineering and can be used in the electrical distribution control of four - and u043fu044fu0442u0438u043fu0440u043eu0432u043eu0434u043du044bu0445 networks with voltage of 0.4 kv with u0437u0430u0437u0435u043cu043bu0435u043du043du043eu0439 neutral for the balancing of the voltage, the current limitation in the zero wire and reducing losses in the power lines with the unbalanced u0444u0430u0437u043du044bu0445 n u0430u0433u0440u0443u0437u043au0430u0445 through compensation for u0444u0430u0437u043du044bu0445 bias currents.the invention solves the problem that the voltage on the load is the maximum u0441u0438u043cu043cu0435u0442u0440u0438u0440u043eu0432u0430u043du0438u0435, limiting the current in the zero wire and reduction losses in the transmission line with the unbalanced u0444u0430u0437u043du044bu0445 loads through compensation for u0444u0430u0437u043du044bu0445 bias currents, which allows to simplify high frequency filters.the design of the transformer has no additional keys and he works in the automatic mode.the task is solved in that a powered saw u0441u0438u043cu043cu0435u0442u0440u0438u0440u0443u044eu0449u0435u043c u0430u0432u0442u043eu0442u0440u0430u043du0441u0444u043eu0440u043cu0430u0442u043eu0440u0435 each compensation u0444u0430u0437u043du0430u044f wire is in the form of three pefc u0435u0434u043eu0432u0430u0442u0435u043bu044cu043du043e united sections, each of which is available on their web u043cu0430u0433u043du0438u0442u043eu043fu0440u043eu0432u043eu0434u0430,the section of each compensation u0444u0430u0437u043du043eu0439 winding connected as open triangles and each second end of the u043fu043eu0434u0441u043eu0435 u0444u0430u0437u043du0430u044f wire compensation u0434u0438u043du0435u043du0430 to the phase of the network. there are other differences from the prototype. u0437u0430u044fu0432u043bu044fu0435u043cu0430u044f construction showed by saving materials and equalization of load stations.
