Closing method for passageway bus bar

Abstract

The invention discloses a closing method for a passageway bus bar, and concretely relates to a closing method for a passageway bus bar when multiple electrolytic cells are shut. The to-be solved technical problems comprise that when a part of electrolytic cells at an electrolysis workshop section are shut at present, routine operation is relatively complex, electrolytic-cell normal production is relatively greatly influenced, power supply equipment has potential safety hazard, and workload and labor intensity of workers are large. The closing method comprises the following steps: 1, arranging a discharging device between two ends A and B of the bus bar, and enabling the discharging switch of the discharging device to be at an off state; 2, after a series of electrolytic cells are powered off, turning on the switch; 3, when the voltage reduction at a discharging circuit-breaking intersection of the discharging device is lower than 0.1 V, finishing short-circuit discharging; and 4, closing the passageway bus bar switch. The method is capable of directly performing closing operation, helps to reduce operation items, shorten serial power-off time and reduce serial running risk, helps to reduce losses such as shutting and secondary starting of two electrolytic cells, and the like, and helps to greatly improve work efficiency.

Description

technical field [0001] The invention relates to an electrolytic cell, in particular to a method for closing an aisle busbar when a plurality of electrolytic cells stop. Background technique [0002] When some electrolytic cells are shut down in the electrolysis section, it is necessary to close the aisle busbar switch. If it is closed directly, it is easy to cause a short circuit accident. According to the conventional operation in the past, it is more complicated. After the whole series of power outages, it is necessary to shut down 4 slots on both sides of the aisle busbar. And raise the anode to separate the anode from the electrolyte to form an open circuit state, and then perform the closing operation. This scheme requires multiple stops in front of the two tanks of the channel bus. If only the two cells in the back are out of service, because although the system is powered off, there is a capacitive effect. Each electrolyzer is equivalent to a capacitor, and the voltag...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that when some electrolytic cells are out of service in the current electrolysis section, the conventional operation is relatively complicated, the normal production of the electrolytic cell is greatly affected, the power supply equipment has potential safety hazards, and the workload and labor intensity of the workers are large. Simple, does not affect the normal production of the electrolyzer, and a safe aisle bus closure method for power supply equipment
