Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, and in particular to a bus duct and a busbar system with a dustproof structure. Background Art

[0002] Bus duct is a closed metal device composed of copper and aluminum busbar columns. It is used to distribute high power to various components of the distributed system. It can carry large currents and distribute electrical energy. It has the advantages of compact structure, easy installation, and large transmission capacity. It has increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] When existing bus ducts are bridged (electrically connected between bus bridges), the copper bars of the two sections of bus duct need to be conductively connected through connectors. After the bridging, the copper bar connections of the bus duct are basically exposed, so it is necessary to install a cover plate at the electrical connection position to prevent external impurities from affecting the normal power supply of the electrical connection position. For example, Chinese patent publication number CN209184190U discloses a bus duct connection cover plate, which is fixed to the two sections of bus duct by screws to build the cover plate above the electrical connection position. Although it can play a certain dust-proof role, due to the inconsistent sizes of the connectors, the same size of connection cover plate cannot be used between different bus ducts. It needs to be customized according to the size of the bus duct and the connector, which has poor versatility and is more cumbersome to install. Summary of the Invention
