Electrically-controlled sliding sleeve and fracturing string

The invention discloses an electrically-controlled sliding sleeve and a fracturing string; the electrically-controlled sliding sleeve comprises: a sliding sleeve body comprising a sliding sleeve shell extended vertically and a sliding core positioned in the shell, wherein the sliding sleeve shell is provided with a liquid outgoing through hole communicated with the outside, the sliding core plugs the liquid outgoing through hole, and the sliding core slides along the length of the shell to open the liquid outgoing through hole; a sensing device that may be arranged above the sliding sleeve body and that generates a magnetic field; an electrically-controlled rod that may pass through the sensing device and that has a sensing mechanism, an actuating mechanism, and a control mechanism, wherein the control mechanism is connected to the sensing mechanism and the actuating mechanism, the control mechanism may control the actuating mechanism to execute expanding action when the sensing mechanism senses the magnetic
