Description

Technical Field

[0001] This utility model relates to an insulating clamping device for short circuits in aluminum electrolysis cells, belonging to the field of aluminum electrolysis short circuit insulation technology. Background Technology

[0002] When the aluminum electrolytic cell is not in operation, the short-circuit block needs to be separated from the column busbar. This is achieved by placing an insulating plate between the short-circuit block and the column busbar. In this state, there are gaps between the short-circuit block and the insulating plate, and between the insulating plate and the column busbar. In a dusty production environment, the presence of these gaps makes it easy for dust to enter, resulting in a dust layer on the contact surface between the short-circuit block and the column busbar. This affects the subsequent contact conductivity between the short-circuit block and the column busbar.

[0003] In other words, a device is needed to prevent dust from forming on the contact surface between the short-circuit block and the busbar, thus ensuring the conductivity of subsequent contact. Summary of the Invention
