Aluminium electrolytic cell emergency short-circuit bus

Abstract

The invention provides an aluminium electrolytic cell emergency short-circuit bus, which comprises a diversion bus and aluminium flexible connection, wherein two ends of the diversion bus are respectively and fixedly connected with one end of the aluminium flexible connection; the other end of the aluminium flexible connection is respectively and fixedly connected with the upper part of the short-circuit bus; the sectional dimension of the diversion bus and the sectional dimension of the short-circuit bus are consistent to the sectional dimension of an electrolytic cell anode rod; the short-circuit bus on one end of the diversion bus is fastened on an anode bus on a discharging side of a short-circuit aluminium electrolytic cell; and the short-circuit bus on the other end of the diversion bus is fastened on an anode bus on a feeding side of an adjacent downstream aluminium electrolytic cell. The aluminium electrolytic cell emergency short-circuit bus has a simple structure and small volume, is convenient to carry, can be quickly inserted into a small box fixture of the anode bus, is convenient to install, is beneficial for reducing a short-circuit process greatly and saving urgent repair time, has good conduction effect, can be popularized and applied in different series of electrolytic plants, and has obvious economic benefit and social benefit.

Description

technical field [0001] The invention relates to an electrolytic cell busbar, in particular to an emergency short-circuit busbar for a large aluminum electrolytic cell. Background technique [0002] The electrolytic cells are connected in series. The busbars of the electrolytic cells include anode busbars, cathode busbars, column busbars and short-circuit busbars. They are not only part of the conductive system of each electrolytic cell, but also an indispensable part of the conductive circuit of the entire electrolytic series. Part. Under normal circumstances, the shutdown of a single electrolyzer is accomplished by the short circuit between the short-circuit busbar and the column busbar. Under abnormal circumstances, if any one of the electrolyzer short-circuit busbars and the short-circuit busbar between the column busbars has a "blasting" phenomenon (that is, a short-circuit discharge phenomenon caused by voltage breakdown of the insulation or air), one situation is to c...

AI Technical Summary

Problems solved by technology

This kind of aluminum electrolytic cell temporary short-circuit busbar is bulky and inconvenient to carry; it also needs to make a special positioning fixture to connect with the anode guide rod, and the newly made positioning fixture increases the production cost of the enterprise

Due to the surface roughness and burrs of the recycled anode guide rod, when the positioning fixture is connected to the anode guide rod, the crimping force of the positioning fixture is not enough, and the clamping surface is not smooth, which will cause a large voltage drop on the crimping surface , and the installation is inconvenient and the installation time is long

In addition, after the blasting accident in the general electrolytic cell, some anode guide rods will be separated from the anode busbar. This kind of aluminum electrolytic cell will not be able to realize the short-circuit function due to the temporary short-circuit busbar.
