Embodiment Construction

[0017] An emergency shunt method for an aluminum electrolytic cell, the emergency cell is withdrawn from the running state and / or the burned-out busbar of the accident cell is short-circuited.

[0018] The said exiting the emergency tank from the operating state is short-circuiting the confluence busbar on the power-incoming side of the accidental tank and the confluent busbar on the power-outgoing side using the emergency tank exiting operation shunt structure, and withdrawing the accidental tank from the operating state.

[0019] The short-circuiting of the burnt-out busbars in the accident tank is to short-circuit the converging busbars at both ends of the burnt-out busbars in the accident tank using the short-circuit and shunt structure of the burnt-out busbars in the accident tank, and repair the burned-out busbars.

[0020] The emergency shunt device for the aluminum electrolytic cell, including the shunt structure for exiting the operation of the accident tank and the sh...

Abstract

The invention belongs to the technical field of aluminum smelting, particularly discloses an emergency shunt method and shunt device of an aluminum electrolysis cell, and aims to solve the problems of long power interruption time of series caused by the fact that the existing electrolysis cell cannot quickly and timely quit operation in case of accidents and the like. According to the method, the accident cell quits the operation state and/or a burnt bus of the accident cell is short-circuited. The device comprises an accident cell operation quit shunt structure and an accident cell burnt bus short-circuiting shunt structure, which both consist of shunt flexible couplings short-circuited between an accident cell current input side bus bar and a current output side bus bar and short-circuited between the bus bars at the two ends of the accident cell burnt bus and special clamps. The influence of accident cell on the entire series production is effectively reduced, the shunt effect is obvious, the operation is easy and convenient, the mounting is facilitated, the short-circuiting process is shortened, the repair time is saved, the conduction effect is good, and meanwhile the method and the device can be popularized and applied to different series of electrolysis shops.

Description

technical field [0001] The invention relates to the technical field of aluminum electrolysis, and relates to an emergency shunting method and shunting method for an aluminum electrolyzer that stops the operation of the accidental electrolyzer or short-circuits the burnt bus when the short-circuit busbar, confluence busbar or short-circuit opening of the electrolyzer explodes. device. Background technique [0002] When an accident occurs in the electrolytic cell, such as the leakage of the short-circuit busbar, the confluence busbar, or the explosion of the short-circuit opening, if emergency measures are not taken, the accidental electrolyzer will be taken out of the running state in time or the burned busbar will be short-circuited for emergency treatment, which will cause serious accidents. The entire electrolysis series is powered off, and in severe cases, the entire series will be paralyzed. At the same time, when repairing the burnt short-circuit busbar and confluence ...
