Technical Field

[0001] The utility model relates to the technical field of copper electrolytic refining, in particular to a novel heavy-duty busbar short-circuiting device. Background Art

[0002] During the copper electrolytic refining process, the electrolytic DC power supply system consists of a rectifier unit, a DC knife switch, a DC bus, an electrolytic cell and a short-circuit switch. In the wet smelting process, each workshop is basically composed of two sets of rectifier equipment, which can be mutually connected through a DC knife switch. The mutual bus spans the two systems. The bus is too long, resulting in the loss of power in the entire mutual bus. In order to reduce energy waste, shorten the bus length and reduce the bus resistance, the traditional method is to drill holes on the existing bus to add short-circuit bus for short-circuiting. Because the bus consists of 12 pieces, the bus needs to be removed and drilled for installation. The bus rectifier unit must be powered off to remove the bus. The bus is heavy and difficult to repair, which takes a long time, directly affecting the output and quality of cathode copper. Utility Model Content
