| description | The invention relates to an elevator automatic rescuing and energy-saving device, an elevator automatic rescuing and energy-saving control method and a supercapacitor module. The method comprises the steps of selecting single phase current in a three-phase power grid to act as an AC power supply of an elevator control system when the power grid is in normal power supply; controlling a DC-DC converter to charge the supercapacitor module connected with the DC-DC converter to specified standby electric energy; and selecting to use the electric energy stored in the supercapacitor module to act as rescuing electric energy of a traction machine and the elevator control system when the power grid is interrupted suddenly. According to the invention, the supercapacitor module is adopted, thereby being capable of providing the stable and reliable elevator rescuing power supply when the power grid is interrupted suddenly. In addition, feedback electric energy dissipated when an elevator is in braking operation can also |
