| description | The utility model discloses a quick charge and discharge management system used for workover rig motor drive. A capacitance management main board is connected with a capacitance management slave board through a CAN bus and is connected with an upper computer, the capacitance management slave board is connected with a signal output end of a current signal collector, the current signal collector is connected at a negative electrode end of a super-capacitor, a total voltage/insulation detection end of the capacitance management slave board is connected with a positive electrode end of the super-capacitor, a capacitance information collection end of the capacitance management slave board is connected in one-to-one correspondence with signal output ends of N super-capacitor modules through N signal terminals, an inverter control output end of the capacitance management slave board is connected with a control input end of a bidirectional DC-DC inverter, a high voltage side of the bidirectional DC-DC inverter is connected with a motor drive system while a low voltage side of the bidirectional DC-DC inverter is connected with the super-capacitor, a charger is connected in parallel at positive and negative electrodes of the super-capacitor, and a control end of the charger is connected with a charger control end of the capacitance management slave board. |
