Description

Technical Field

[0001] The utility model relates to the technical field of single crystal silicon preparation, in particular to a single crystal furnace aluminum row connection structure. Background Art

[0002] At present, the heating connection method of the single crystal furnace is that the power cabinet is placed on the side. The side space is tight and there is no room for expanding new functions. At the same time, the aluminum bars of the power cabinet are staggered front and back. During installation, multiple sections of aluminum bars need to be bent and routed, resulting in a large number of joints. During operation, too many joints cause serious heat generation at the joints, large power loss, and poor safety. During the installation process, there is a waste of aluminum bars and installation difficulties.

[0003] like Figure 1-Figure 2 As shown, the original connection method is to place the power cabinet on the side, which can ensure that there is enough space for the power cabinet to be installed, but at the same time it causes crowding of the side space and no space expansion function. The original aluminum busbar wiring can be effectively connected to the power cabinet, but the connection is complicated and there will be many aluminum busbar joints. During operation, too many joints will increase circuit loss, cause serious heat generation, and have poor safety, which also brings difficulties to on-site installation. The side placement of the power cabinet causes crowding of the side space of the cement platform, and no expansion space is reserved for the furnace body upgrade. In addition, the aluminum busbar has a single limit and poor installation stability. For this reason, we propose a single crystal furnace aluminum busbar connection structure. Utility Model Content
