Technical Field

[0001] The utility model relates to the technical field of short-circuiting devices, in particular to a stop slot busbar short-circuiting device. Background Art

[0002] Aluminum and aluminum alloys are widely used. The output and consumption of aluminum are second only to steel. Aluminum resources are very abundant, so it is also one of the most economical and applicable materials. Electrolytic aluminum is obtained by passing direct current to the two poles of the electrolytic cell and performing electrochemical reactions at the two poles in the electrolytic cell. It is also an important production method of aluminum.

[0003] The Chinese invention patent with the announcement number CN112522742B discloses an electrolytic cell connection channel, including a channel housing and a melt channel arranged in the channel housing, wherein the melt channel is in fluid communication with the electrolytic cell. The invention also discloses a method for using the electrolytic cell connection channel. Multiple electrolytic cells can be connected to realize the assembly line operation of the electrolysis process, and the feeding and extraction of magnesium can be centralized, which greatly reduces the labor intensity. By matching the functions of refining electrolyte and collecting and refining products, it is possible to produce high-quality products from low-grade raw materials.

[0004] In the above-mentioned electrolytic cell connection channel, multiple electrolytic cells are connected in series, and the DC power passes through all the electrolytic cells in turn. When one of the electrolytic cells is out of operation for rotation and overhaul, a short-circuit is used for short-circuiting.

The conventional short-circuit is connected by crimping and reinforced with screws and bolts. Affected by factors such as uneven crimping surface and dust, the short-circuit voltage drop is high, and the voltage drop after stopping the cell is large, resulting in a lot of idle power consumption. Therefore, there is a problem of high idle power consumption when the electrolytic cell in the prior art is short-circuited. Utility Model Content
