Provided is a shunt diverter. A top groove plate and a bottom groove plate of the shunt diverter are connected with a side plate. A guide groove is disposed on the side plate. A compacting slide block cooperates with the guide groove. The top of a diverting rod is connected with the compacting slide block. A connecting sleeve is disposed in a threaded through hole on the bottom groove plate. The top of a fixed insulated sleeve is connected with the bottom groove plate. The bottom of the diverting rod is connected with a handle at the bottom end of a movable insulated sleeve through the connecting sleeve and the fixed insulated sleeve. A part, between the compacting slide block and the connecting sleeve, of the diverting rod is sleeved by a compacting spring. The shunt diverter is not restricted by zero load, overcomes a problem that narrow equipment clearance cannot achieve heat treatment in a live working state when ground potential operation is used, prevents load transferring and repeated switching operation. The guide groove guides the sliding of the compacting slide block such that the up-down movement of the compacting slide block is not liable to offset. The connecting sleeve adjusts and sets the elastic variable of the compacting spring so as to guarantee reliable clamping of wire clamp pressing plate with different thicknesses. The synchronization of the down movement of the movable insulated sleeve and the diverting rod always enables the diverting rod to be protected in the movable insulated sleeve, thereby improving security.
