[0002] With the rapid development of social economy, there are more and more high-rise buildings, and the population density in high-rise buildings is obvious. The power load has increased sharply. The increase in power load will inevitably bring fire hazards. Preventing the occurrence of power fires is of great significance. The power consumption of all walks of life has increased rapidly, especially with the emergence of numerous high-rise buildings and large factories and workshops. Traditional cables as transmission conductors can no longer meet the requirements in high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to the on-site installation and construction connection. Plug-in bus ducts have emerged as a new type of distribution conductor.

[0003] Some existing dust-proof bus ducts are equipped with dust removal devices at the heat dissipation mesh holes, but some dust will remain inside the bus duct body. The dust inside the shell adheres to the terminal block body and affects the heat dissipation of the wires. At the same time, there is no moisture-proof device installed inside the existing dust-proof bus duct. The interior of the bus duct will become humid after passing through the rainforest, which will cause safety hazards. Utility Model Content
