Tit:
Here are a few things we need to know:
(1) As shown in the figure below, the connection of copper and aluminum busbar needs to consider the combination of two substances
a) Elemental potential difference between copper and aluminum will cause electrochemical corrosion
b) At high temperatures, the two elements may form intermediate compounds and the interface resistance increases and becomes brittle
c) When processing here, the coating process is performed on the aluminum Busbar, and the joint is sealed after welding (to form a gas-tight condition to block electrochemical corrosion)
d) The expansion coefficient of aluminum is up to 39% greater than that of copper. When two metal conductors are connected and pass current, the connection point is heated due to the contact resistance, and both conductors are expanded. If the temperature rise control is not reasonable, it may cause some potential problems.
(2) Some problems are relatively small if copper-aluminum Busbar transfer is used. If the transfer is not used, how to ensure the long-term reliability of the contact without the sealant has challenged us.
