Abstract
Description
Technical Field
[0001] The invention relates to a connecting busbar structure used for connecting a busbar duct and a transformer. Background Art
[0002] With the emergence of modern engineering facilities and equipment, electricity consumption across all industries has increased rapidly, particularly with the proliferation of high-rise buildings and large factories and workshops. Traditional cables, used as transmission conductors, are no longer sufficient for high-current transmission systems. The parallel connection of multiple cables creates significant inconvenience during on-site installation and connection. Consequently, busbar ducts have emerged as a new type of power distribution conductor. Due to their low capacity, inconvenient branching, and inconvenient bundle management, existing wires and cables have been gradually replaced by busbar ducts, which offer high capacity, convenient branching, and easy bundle management. Compared to traditional cables, busbar ducts demonstrate their superiority in high-current transmission. Furthermore, the use of new technologies and processes significantly reduces contact resistance and temperature rise at the busbar duct's end connections and at the branching ports. The use of high-quality insulation materials within the busbar duct enhances its safety and reliability, further improving the overall system. Busbar ducts are widely used in key projects such as power transmission trunk lines for firefighting equipment and fire emergency equipment, including those in hotels, airports, and subways. Therefore, busbar duct product performance is crucial. Summary of the Invention
