Description

Technical Field

[0001] The invention relates to the technical field of busbars, and in particular to a busbar with an expansion joint for a wind tower. Background Art

[0002] The busbar, also known as the busbar, is a group of power transmission devices that provide power to mobile equipment.

[0003] Mobile equipment needs to constantly change its position due to movement. At each different position, the mobile equipment needs to be able to obtain power supply at any time, so busbars came into being. Several conductors are laid in parallel along the running track of the mobile equipment and connected to the power supply. On the moving equipment, a collector that can draw power from the conductor is installed. In this way, when the equipment moves, the collector runs synchronously with the equipment and obtains power from the conductor at any time to provide it to the equipment so that the equipment can continue to move. The device composed of these conductors and collectors is called a busbar.

[0004] In the wind power industry, wind towers are usually divided into several sections before installation, and the busbars need to be pre-installed separately in each tower. However, due to the large size of the towers, there are errors between the towers, and there are gaps of 10-50mm between the busbars, which results in the pre-installed busbars needing to be adjusted downwards section by section, which is a huge workload and is not convenient to use.
