Description

technical field [0001] The invention relates to the technical field of power transmission, in particular to a copper conductor-intensive busway with an L-shaped aluminum heat sink. Background technique [0002] The busway is a closed metal device composed of copper and aluminum busbar columns, which is used to distribute large power to various components of the decentralized system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects. [0003] The existing busway generally consists of left and right side plates, upper and lower cover plates to form a sealed shell, and there are L1 phase, N phase, L2 phase, L3 phase copper conductors for power transmission inside the shell, and L1 phase, N phase, The L2 phase and L3 phase copper conductors are made of copper conductors. Because the shell is sealed, heat is easy to accumulate inside the shell, and the copper conductor itself has resistance, so the copper conductor will al...

[0003] The existing busway generally consists of left and right side plates, upper and lower cover plates to form a sealed shell, and there are L1 phase, N phase, L2 phase, L3 phase copper conductors for power transmission inside the shell, and L1 phase, N phase, The L2 phase and L3 phase copper conductors are made of copper conductors. Because the shell is sealed, heat is easy to accumulate inside the shell, and the copper conductor itself has resistance, so the copper conductor will also generate heat, so the busway is easy to generate heat. Heat is also easy to accumulate heat, which leads to higher temperature of the busway, and the busway is now relying on natural heat dissipation, or relying on external blowing to dissipate heat, resulting in low heat dissipation efficiency and the temperature of the busway cannot be reduced to an ideal state. , and the temperature of the bus duct is too high, which will lead to an increase in the resistance of the conductor, which will increase the energy consumption during the transmission of electric energy, and the accumulation of heat will also easily lead to the aging of the conductor and affect the service life of the conductor. At the same time, the bus duct also has Potential threat of fire is likely to occur, so there is an urgent need for a heat dissipation structure with a simple structure, which can quickly discharge the heat in the bus duct
