Description

Technical Field

[0001] The utility model relates to the field of Acheson graphitization furnace power transmission device, in particular to an automatic lifting mechanism for a busbar clamp assembly. Background Art

[0002] Acheson graphitization furnace is a resistance furnace that uses carbon roasted products and resistor materials as the furnace core, passes AC power, and produces artificial graphite products. When the current passes through the resistance of the furnace core, the electrical energy is converted into heat energy, heating the carbon roasted products to a high temperature of 2300-3000℃, completing the graphitization process and forming artificial graphite products. The Chinese name is AC graphitization furnace, and it is also customarily called Acheson furnace.

[0003] Acheson furnaces are intermittently operated. In one production cycle, they have to go through processes such as furnace loading, power supply, cooling, furnace unloading, and maintenance, which takes a total of 12 to 15 days, and power supply only takes 3 to 5 days. Generally, one transformer can be equipped with 5 to 7 furnaces of the same specifications to form a furnace group, and a furnace group is a production unit. During production, the transformer runs continuously and the furnaces work in turn; usually one furnace in a furnace group is in the power-on state, and the other furnaces are in the states of furnace loading, cooling, loading and unloading or maintenance; after one furnace is finished working, power is supplied to the next furnace.

[0004] The busbar clamp currently used for clamping the busbar is easily dislocated by gravity when clamping the busbar, resulting in a smaller contact area between the busbar electrode plate and the busbar, which in turn leads to increased heat generation.
