FIELD: electrical engineering.
SUBSTANCE: invention relates to application of auxiliary needs for heating and lighting of substation and electric power stations buildings. Output of power transformer by means of oil cooling pump is connected to input of first oil circulation pipeline, connected to four cooling radiators, outputs of each of which are connected to a pair of fans of air coolers connected to a pair of suction funnels of air cooling respectively. Shaft of oil cooling pump is rigidly connected to shafts of reactive-valve generators and reactive-valve motors, which outputs are connected to inputs of control units. Outputs of control units are connected to electric energy accumulator and are connected to power supply source by electric energy through disconnectors. Outputs of reactive-valve generators are connected to electric energy accumulator connected to power supply source by means of disconnector via disconnectors.
EFFECT: technical result consists in improvement of energy efficiency.
