Balance protection device for bus of aluminum electrolysis cell

The utility model relates to a bus balance protection device for an aluminum electrolysis cell. The bus balance protection device comprises a first position sensor, a second position sensor and an alarm device, the first position sensor detects the horizontal position of an A-side bus of the aluminum electrolysis cell, the second position sensor detects the horizontal position of a B-side bus of the aluminum electrolysis cell, the alarm device obtains the position difference between the horizontal position of the A-side bus and the horizontal position of the B-side bus, and when the position difference is larger than a position difference alarm threshold value, an alarm is given. According to the utility model, the horizontal positions of the A-side bus and the B-side bus are monitored in real time, and when the difference between the horizontal positions of the buses on the two sides exceeds a set value, an alarm is automatically given in real time. 本实用新型涉及一种铝电解槽母线平衡保护装置，包括第一位置传感器、第二位置传感器和报警装置。第一位置传感器检测铝电解槽的
