Description

Technical Field

[0001] This utility model relates to the field of aluminum electrolysis technology, and in particular to a short-circuiting device for the busbar around the electrolytic cell. Background Technology

[0002] Electrolytic cells are important equipment in aluminum electrolysis production, and the cell perimeter busbar is the conductor connecting the two sides of the electrolytic cell. It is also called "slot pattern busbar" or "cross-slot busbar". Electrolytic cell perimeter busbars are usually made of aluminum alloy or aluminum-copper composite materials. They are an extremely important component of the electrolytic cell. In addition to transmitting current, the electrolytic cell perimeter busbar can also maintain temperature and improve production efficiency.

[0003] During normal operation of an electrolytic cell, the peripheral busbar is responsible for current transmission. However, when the electrolytic cell stops operating (such as during major repairs or temporary shutdowns), the peripheral busbar still needs to maintain a current path to ensure equipment safety. If the path of the peripheral busbar is too long or its resistance is too high, it will cause a significant reactive voltage drop in the peripheral busbar (usually manifested as voltage fluctuations or increased energy consumption).

[0004] By temporarily short-circuiting part of the electrolytic cell's peripheral busbar, the current path can be shortened and the resistance reduced, thereby reducing the voltage drop during cell shutdown. This reduces reactive voltage loss and energy waste, effectively solving the problem of excessive reactive voltage loss during cell shutdown, and achieving both energy saving and cost reduction.

[0005] The traditional method of short-circuiting the busbar around the electrolytic cell involves using a clamp to connect the busbar around the electrolytic cell to the short-circuit connection line after the cell is shut down. This method is inconvenient and requires two or more people to lift the short-circuit connection line, install the clamp, and tighten it. Furthermore, positioning during installation is difficult, and the clamp is hard to fix under the influence of a magnetic field. Utility Model Content
