Measuring apparatus for current of busbar in aluminum cell, and measuring system and method for anode current

Abstract

Embodiments in the invention provide a measuring apparatus for the current of a busbar in an aluminum cell, and a measuring system and method for anode current. The busbar current measuring apparatus is applied to measurement of busbar current of the aluminum cell, and is arranged on a busbar which is located at one side of an anode rod of the aluminum cell. The busbar current measuring apparatus comprises a snapping rack and a busbar current collector, wherein the snapping rack comprises a busbar voltage and temperature collector and a locking device respectively arranged at two ends of the snapping rack; the busbar current measuring apparatus is fixed on the busbar which is located at one side of the anode rod via the busbar voltage and temperature collector and the locking device; and the busbar current collector is arranged on the snapping rack and used for determining the resistance of the busbar according to busbar temperature fed back by the busbar voltage and temperature collector, acquiring the current of busbar located at one side of the anode rod according to the resistance of the busbar and equidistant voltage of the busbar fed back by the busbar voltage, and sending the current. An anode current measurement scheme provided in the embodiments in the invention overcomes the defect that a measuring apparatus needs to be directly loaded on the anode rod during measurement of anode current in the prior art.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of aluminum electrolysis, and in particular to a busbar current measuring device for an aluminum electrolytic cell and an anode current measuring system and method. Background technique [0002] At present, in the existing aluminum electrolysis industry, in the production process of prebaked electrolytic cells, it is necessary to measure the distribution of anode current every day, which is measured by manual measurement means of off-line equidistant voltage drop. [0003] However, since this measurement method cannot eliminate the influence of the temperature change of the anode guide rod on the anode current measurement, there is a large measurement error; in addition, because manual measurement can only measure one anode at a time, after the operation The measurement of the next anode is carried out again and again, not only the measurement procedure is complicated, the workload ...
