Busbar processing technology

 

Visual inspection: The surface of the material used to make the busbars should be flat and clean, and there should be no cracks or cracks.

Surface scratches, pores, pits, peeling and other defects caused by defects, the copper bus bar should not exceed

Calculate 3% of the cross section, the aluminum busbar should not exceed 5%.

7.2 Correction: There are two types of correction methods: mechanical correction and manual correction. Mechanical correction is generally used for busbars with a larger cross section of 5×40 or larger, which are straightened by a straightener and rolled by a flattening machine. During manual correction, the mother can be discharged On the platform, use a hard wooden hammer to directly hit straight, or use a wooden hammer or a pad (copper, aluminum, wooden pad can be used), and use the sledgehammer to directly hit the straight on the busbar. Appropriate, not too fierce, otherwise it will cause deformation of the busbar.

7.3 Measurement: The bending size of the busbar on the design drawing is calculated under certain conditions. When used for installation, the drawing is for reference only. The processing of the busbar is generally made according to the on-site measurement results.When measuring, a wire hammer. Use a tape measure and other tools to draw a large sample of the measured size on a small blackboard or platform. Another simple and practical method is to use 8# steel wire to bend into a template as the basis for the bending of the busbar.

7.4 Cutting: The cutting method of the busbar is not clearly specified. According to the processing capacity and processing convenience of the equipment, sawing or punching is selected, mostly punching.

7.5 Bend:

7.5.1 There are three types of rectangular busbars: flat, vertical, and twisted. The typical bending forms are shown in Figure 4.

Rectangular busbars should be reduced at right angles. There should be no cracks or significant wrinkles at the bends.

The diameter should not be less than the provisions of Table 11:
