PULSE-CONTROL METHOD discontinuous energy supply in the drying process humidification INSULATION windings of electrical machines locomotives

摘要

Method ehnergopodvoda control in processes of drying hydrated insulation of windings of electrical machines traction of rolling stock, according to which is done the forced blowing of air flow, thermal heating, control of the operating temperature and the state of insulation, characterized in that the energy supply in the drying process is carried out by pulse-discontinuous method for controlling an electric heater, based on what remains unchanged Tc cycle period, during which the enable and disable elektronag evatelya, interval τp varies depending on the degree of isolation humidification during which the electric heater is turned on.
