Description

Technical Field

[0001] The utility model relates to a telescopically adjustable bus duct, belonging to the technical field of power transmission. 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 has increasingly replaced wires and cables in indoor low-voltage power transmission trunk projects. The original circuit wiring method, that is, the pipe wiring method, brings many difficulties during construction. Moreover, when the distribution system needs to be changed, it is almost impossible to make it simpler. However, if bus duct is used, the purpose can be achieved very easily and the building can also be made more beautiful.

[0003] During use, the existing bus ducts are usually arranged in an integrated manner, and then after multiple bus ducts are connected, they are easily longer than the laying space, or the distance is insufficient, which affects the precise installation of the end heads, thereby reducing the use effect of the bus duct; and when the bus ducts are connected, fixing parts are usually used to connect two adjacent bus ducts. Although this method is stable, the disassembly and assembly process is relatively cumbersome, thereby reducing the convenience of connecting or splitting the bus ducts. Utility Model Content
