Polycrystalline silicon reduction furnace bus fixing support

The utility model belongs to the technical field of polycrystalline silicon reduction furnace buses, and particularly relates to a polycrystalline silicon reduction furnace bus fixing support. The polycrystalline silicon reduction furnace bus fixing support comprises a supporting frame, a plurality of bus fixing frames and an insulating clamping seat. A frame is defined by the tops of the supporting frames. One end of each bus fixing frame is installed on the frame, and the other end of each bus fixing frame extends towards the inner side of the frame. The insulating clamping seat is installed at the other ends of the plurality of bus fixing frames, and the insulating clamping seat is used for clamping and fixing a bus. According to the polycrystalline silicon reduction furnace bus fixing support, the structure of the support is stable and reliable, the buses are fixed through the multiple bus fixing frames and the insulation clamping bases, and field personnel can conveniently overhaul and maintain reduction
