Busbar production and installation process requirements
The configuration of the busbars should be horizontal, vertical, well-defined, neat and beautiful. The lap joints should be naturally coincident and properly fitted without installation stress. The actual contact area of the lap joints should not be less than twice the cross-section of the busbar.
6.2 Except for the necessary bending and radian, the bus bar itself must not be bent.
6.3 The surface of the busbar should be smooth and smooth after blanking and straightening, and there should be no obvious pits and scratches. The punching edges should be flat and chamfered.
6.4 The typical bending shape of the bus bar is shown in Figure 1 and Figure 2, and its bending radius is implemented according to Table 2 and Table 3. When the bus bar is bent flat, no cracks shall appear, and when the bus bar is bent upright, no obvious wrinkles and twists shall appear.
6.5 For the bending and installation of the bus bar, the safety of electrical operation should be considered as much as possible, and sufficient distance should be considered to allow the user to enter the line and installation and maintenance are convenient. Special attention should be paid to the installation of the pile head wiring on the air circuit breaker and fuse to the inside.
6.6 When the busbar needs to be painted, the paint shall be sprayed or painted. The color should be even, the edges should be neat, and there should be no paint leakage or sagging, and no paint should be dipped at the busbar overlap. The same component,
The paint boundary of each phase bus at the same end should be free of obvious irregularities. The paint limit of the overlapped bus is shown in Figure 3, and the paint limit of the secondary line connected to the bus is shown in Figure 4.
6.7 The configuration of busbars should minimize lap joints. Its connection Figure 3 The paint limit of the busbar connection Figure 4 The paint limit of the secondary busbar connected to the busbar
