Embodiment 1

[0020] Embodiment 1: see attachment figure 1 , in an emergency state, one end of the emergency short-circuit bus 1 is connected to the column bus 2 below the short-circuit opening of the aluminum electrolytic cell, and the other end is connected to the short-circuit bus 3 below the short-circuit block 4, so that the current entering the column bus 2 is directly guided by the emergency short-circuit bus 1 The short-circuit busbar 3 below the short-circuit block 4, the emergency short-circuit busbar 1 is connected with a conductor or two conductors and a copper soft strip or an aluminum soft strip soft connection 5 at both ends, the conductor material is aluminum profile or copper material, and the copper strip soft connection and the conductor are composed The emergency short-circuit busbar, because of its flexibility, is easy to assemble and disassemble, and saves time and effort for installation.

[0021] The emergency short-circuit busbar 1 is crimped with the side of the co...

Embodiment 2

[0024] Embodiment 2: see attachment figure 2 , 3 , The two ends of the emergency short-circuit busbar 1 are crimped with the sides of the column busbar 2 and the short-circuit busbar 3, and the connection method is crimped with a door-shaped fixture or a bow-shaped fixture.

[0025] It is used in the accident state of the electrolytic cell. When the short circuit of the electrolytic cell explodes, the electrolytic cell stops, and the series of currents are difficult to enter the busbar around the tank through the short circuit block. The emergency short circuit busbar 1 is used as a bypass device to temporarily pass the current to Avoid downtime of the electrolytic series.

Abstract

The invention discloses an aluminum electrolysis cell emergency short-circuiting device. The aluminum electrolysis cell emergency short-circuiting device comprises an emergency short-circuiting bus. One end of the emergency short-circuiting bus is connected with a riser bus located below a short-circuiting port of an aluminum electrolysis cell, and the other end of the emergency short-circuiting bus is connected with a short-circuiting bus below an electrolysis cell short-circuiting block. Currents are directly guided to the short-circuiting bus below the short-circuiting block from the riserside located below the short-circuiting port through the emergency short-circuiting bus and do not need to flow through the short-circuiting block and the riser bus at the position of the short-circuiting port, and therefore the technical problems that in the prior art, a device cannot be completely suitable for the situation that the short-circuiting port fails, and emergency processing is hardlyachieved once an accident of the short-circuiting port happens can be effectively solved.

Description

technical field [0001] The invention relates to an emergency short-circuit device for an aluminum electrolytic cell, belonging to the technical field of aluminum electrolytic equipment. Background technique [0002] The electrolytic series is a closed circuit with strong current. The current direction of the operating state of a single electrolytic cell is: column busbar→anode horizontal busbar→anode guide rod→anode→electrolyte→aluminum water→cathode→cathode steel bar→cathode soft connection→busbar around the cell→column of the next cell Busbar; when the slot is stopped, the current direction is: column busbar → short-circuit opening → slot bottom busbar → column busbar of the next slot. [0003] In an accident state, if a short-circuit explosion occurs, there is no other way except to stop the accident electrolyzer urgently. The so-called rescue is to stop the accident slot as soon as possible and restore the normal power transmission of the series as soon as possible. On...
