Description

Technical Field

[0001] The present application relates to the technical field of bus duct heat dissipation, and in particular to a bus duct with internal and external heat dissipation. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbars. It is used to distribute large power to various components of the distributed system. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk projects. When the bus duct is working, a lot of heat will be generated inside. The heat needs to be dissipated inside the bus duct, otherwise it will affect the service life of the bus duct.

When a large amount of heat accumulates in the bus duct, if the heat cannot be dissipated in time, it is easy to cause the temperature in the bus duct to continue to rise, thereby damaging the internal electrical components. The bus duct includes a first bus duct body and a second bus duct body, and the first bus duct body and the second bus duct body are connected through a heat dissipation component; by providing a through hole, when the temperature in the installation box exceeds the standard, the baffle can be raised by starting the forward and reverse motors, that is, the heat in the installation box can be discharged through the heat dissipation holes, and by providing a heat dissipation fan, the air circulation speed can be further accelerated, greatly accelerating the heat dissipation efficiency of the first bus duct body and the second bus duct body.

[0004] With respect to the above-mentioned related technologies, the inventors have found the following defects: the connection between the heat dissipation assembly and the bus duct body in the above-mentioned scheme is a fixed connection and cannot be disassembled. After the heat dissipation assembly has been used for a period of time, if the components inside the heat dissipation assembly are damaged, they cannot be disassembled separately for repair and replacement.

[0032] The implementation principle of a bus duct with internal and external heat dissipation in the embodiment of the present application is as follows: the two connecting rods 9 are simultaneously moved toward the middle of the fixed box 3, and the fixing block 8 is driven by the connecting rod 9 to move on the inner wall of the sliding cavity 4, so that the limiting rod 6 can be separated from the limiting hole 7, and then the limiting rod 6 can be moved to the inside of the sliding cavity 4, and then the connecting rod 9 can be pulled upward to drive the fixed box 3 to move upward, so that it is convenient for the staff to disassemble and repair the heat dissipation components in the fixed box 3.
