Calculation methods for the current carrying capacity of copper busbars and aluminum busbars The calculation of the current carrying capacity of copper busbars and aluminum busbars is an important part of electrical engineering, which directly affects the operational safety and efficiency of electrical equipment.. The following is the specific calculation method for the current carrying capacity of copper busbars and aluminum busbars:

1. Estimation method for the current carrying capacity of copper busbars: Single copper busbar current carrying capacity=width (mm) × thickness coefficient Double busbar current carrying capacity=width (mm) × thickness coefficient × 1.5 (empirical coefficient) Common thickness coefficients (at 40 ℃): 12mm thickness is 20, 10mm thickness is 18, 8mm thickness is 16, 6mm thickness is 14, 5mm thickness is 13, 4mm thickness is 12. Accurate calculation method: Single layer copper busbar current carrying capacity (at 40 ℃)=busbar width x thickness coefficient (selected according to busbar thickness) Double layer copper busbar current carrying capacity (at 40 ℃)=1.56-1.58 x single layer copper busbar cu

rrent carrying capacity (at 40 ℃) Three layer copper busbar current carrying capacity (at 40 ℃)=2 x single layer copper busbar current carrying capacity (at 40 ℃) Four layer copper busbar current carrying capacity (at 40 ℃)=single layer copper busbar current carrying capacity (at 40 ℃) x 2.45 (not recommended, it is best to use a non-standard busbar as a substitute) Copper busbar current carrying capacity (at 25 ℃) can be obtained by multiplying the current carrying capacity at 40 ℃ by 0.85. Concise calculation formula: Current carrying capacity of a single rectangular copper busbar (at 40 ℃)=busbar width × (busbar thickness+8.5) A double-layer current carrying capacity=1.5 times single-layer current carrying capacity Three layer current carrying capacity=2.0 times single-layer current carrying capacity

2. Formula for calculating current carrying capacity of aluminum busbar: To calculate current carrying capacity of aluminum busbar quickly, multiply the busbar width coefficient; Thick three rows, width by ten, rear four rows, width by twelve; Add one in sequence (for every 1mm increase in thickness, the coefficient increases by 1), and then multiply the copper bar by 1.3. Specific coefficients: 3mm thickness is row width x 10, 4mm thickness is row width x 12, 5mm thickness is row width x 13, 6mm thickness is row width x 14, 8mm thickness is row width x 16, and 10mm thickness is row width x 18. Accurate calculation method (based on copper busbar conversion): First, consider the aluminum busbar as a copper busbar of the same specification, and calculate the current carrying capacity according to the above copper busbar calculation method; Then multiply the obtained copper busbar current carrying capacity by 0.77 (i.e
