However, the closed bus duct has poor heat dissipation efficiency. When the conductor inside the bus duct is energized and generates heat, the heat inside the bus duct is not easy to dissipate, which can easily cause the bus duct and the conductor temperature to rise, causing the conductor resistance to increase, and increasing the loss of the transmission line.

[0012] The utility model provides a bus duct which is beneficial to the discharge of hot air and has the following beneficial effects:

[0013] The utility model provides a ventilation structure installed on the bus duct, which is composed of two groups of duct covers and exhaust fans. The exhaust fans of the two groups of ventilation structures rotate in opposite directions. When the ventilation structure is started, the airflow enters the bus duct from one end, flows through the bus duct and then flows out through the other end. The airflow takes away the heat inside the bus duct, cools the bus duct, reduces the temperature of the conductor inside the bus duct, and thus reduces the resistance value of the conductor, which is beneficial to reducing the loss generated in the power transmission process and reducing the probability of deterioration and combustion of the insulation layer of the bus duct due to overheating.

[0015] In addition, the ventilation structure can be disassembled from the lower slot plate. When disassembling, pull the docking lock column outward to make the inner end of the docking lock column disengage from the docking slot, then the drainage cover can be pulled out from the docking sleeve, and the ventilation structure can be quickly disassembled, which is convenient for cleaning and maintenance of the bus duct and exhaust fan.
