铝电解槽系列母线零点漂移的探索

Exploration on busbar zerowander of aluminium electrolytic cell

铝电解槽系列母线零点漂移主要是由于测量电压时的参考零点电位发生变化造成的,零点漂移的程度与其接地点的地质状况、绝缘损坏程度、接地点的多少和接地处电位高低等因素密切相关,是各个接地点共同作用的结果。

The busbar zerowander of aluminum electrolytic cell is mainly due to the change of reference zero potential when the voltage is measured. The extent of zerowander is closely related to the factors such as geological condition of its earthing point, the damaging extent of insulation, number of the earthing points and the potential of earthing spot etc, and it＇s a result of the interaction of each earthing point. The loop constituted by busbars of cell trains throughthe ground will cause little electric leakage and damage, while the loop constituted by electrolytic cell through the metal under the earth will cause much electric leakage and damage.
