The invention relates to a method for on-load shearing and reconnecting a 10kV overhead bare conductor, which comprises the following steps: S1, hanging a conductor clamping device, a tension traction conversion tool, a backup protection conductor clamping device and an insulating rope, S2, installing an insulating drainage wire, S3, measuring current, S4, cutting off the conductor and connecting and pressing the conductors on two sides by using a conductor connecting fitting, S5, measuring current, S6, cutting off the conductor, and S5, reconnecting the conductor. S6, the tension traction conversion tool and the wire clamping device are dismantled; the tension traction conversion tool has the advantages that when the wire is cut off and the wire connection fitting is used for connecting and pressing the wires on the two sides, the insulation drainage wire is mounted on the tension traction conversion tool, so that the current of the wire can be shunted to the insulation drainage wire, and after the wire connection fitting is connected and pressed with the wires on the two sides, the current circulation can be realized through the wire connection fitting; therefore, reconnection of the overhead bare conductor can be realized in an on-load state, power failure of a user is avoided, the conductor operates in an on-load manner in the whole process, power utilization of any user is not affected, and power utilization stability is guaranteed.
