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.
