Front-end shunting device for starting and stopping of aluminum electrolysis cell

The utility model relates to the field of aluminum electrolysis, in particular to a front-end shunting device for starting and stopping of an aluminum electrolysis cell, and solves the problems that existing shunts are large in size, heavy, inconvenient to mount and dismount, high in replacement cost, long in period and the like. The front-end shunting device comprises a shunting component, a connecting piece I, a connecting piece II and a Cell switch, wherein two ends of the shunting component are connected with two sides of the Cell switch through the connecting piece I and the connecting piece II, a freely detachable short-circuit insulation board is additionally arranged on the connecting piece II, and the shunting component consists of multiple groups of steel strips and explosion blocks welded at two ends of each steel strip; the connecting piece I is formed by vertically welding a transverse aluminum plate I and a vertical aluminum plate I; the connecting piece II consists of a transverse aluminum plate II, a vertical aluminum plate II and a flexible coupling connected with the transverse aluminum plate II. The shunting device is used for shunting for starting and stopping of the electrolysis cell, has the characteristics of roasting current shunting uniformity, short roasting time, obvious electricity saving effect, simplicity and convenience in operation, convenience in mounting and dismounting, low maintenance and production cost, high practicability and the like and has higher popularization and use values.
