Background

The bus duct is a closed metal device composed of copper and aluminum bus posts and used for distributing large power for each element of a dispersion system. The intensive bus adopts an aluminum-magnesium alloy outer shell for heat dissipation. In order to ensure the safe and normal work of the bus duct, the working temperature index of the bus duct is that the copper conductor body must be less than 70 ℃ and the aluminum magnesium alloy shell must be less than 55 ℃ according to the relevant standards set by the state. Therefore, when the rated current passing through the bus duct is larger, the row rule of the copper conductor needs to be selected larger according to a certain proportion to adapt to the current intensity, and therefore the temperature rise of the bus duct is controlled within a specified range. Therefore, there is a need for a heat sink for a compact busway.
