Problems solved by technology

[0004] The purpose of the present invention is to provide an emergency short-circuit device for an aluminum electrolytic cell to solve the problem of short-term failure of the accident cell when a short-circuit explosion or accidental leakage occurs in a certain electrolytic cell in the series when the cell stops unplanned. If it cannot be recovered, it will lead to a series of shutdowns, causing extremely serious economic losses and impacts

Embodiment Construction

[0011] refer to figure 1 , the emergency short-circuit device for an aluminum electrolytic cell includes a short-circuit bus 1 , a first clamp 2 and a second clamp 3 , and the first clamp 2 and the second clamp 3 are respectively arranged at both ends of the short-circuit bus 1 . The short-circuit busbar 1 is composed of a crimping block 11, a first flexible strip 12, a first busbar 13, a second flexible strip 14 and a second busbar 15 connected in sequence. The first flexible strip 12 and the second flexible strip 14 are aluminum busbar flexible strips, the number of flexible strips of the first flexible strip 12 and the second flexible strip 14 is designed below the safe current density, and the length of the flexible strip is based on the specific groove type However, the connection between the crimping block 11 , the first flexible strip 12 , the first busbar 13 , the second flexible strip 14 and the second busbar 15 is all welded.

Abstract

The invention discloses an aluminum electrolytic cell emergency short circuit device. The problems that the whole series of aluminum electrolytic cells are stopped and extremely severe economic losses and influences are caused if the accident aluminum electrolytic cell cannot be restored in a short time when a certain aluminum electrolytic cell in the series is subjected to short circuit orifice explosion or accidental cell leakage are solved. The device comprises a short circuit bus, a first clamp and a second clamp, wherein the first clamp and the second clamp are respectively arranged at two ends of the short circuit bus. The device disclosed by the invention is used for aluminum electrolysis production.

Description

technical field [0001] The invention relates to an emergency short-circuit device, in particular to an emergency device for short-circuiting an aluminum electrolytic cell. Background technique [0002] The electrolytic cell is the main equipment of the aluminum plant. An electrolytic series generally has more than 200 electrolytic cells connected in series. When one of the electrolyzers cannot maintain normal production, it needs to be short-circuited in order to withdraw from production for overhaul, which is called shutdown. The overhauled electrolyzer is put into energized operation, which is called slotting. When the electrolytic cell is stopped and opened, it involves the operation of converting a large current of hundreds of kiloamperes from one part of the busbar to another part of the busbar. At present, when stopping and opening the slot, it is necessary to cut off the power or reduce the current of the entire electrolytic series for about ten minutes, disassembl...
