With the continuous development of power electronics technology, laminated busbar, as a new type of power transmission and distribution equipment, has gradually received widespread attention. A laminated busbar is a kind of busbar consisting of two or more layers of prefabricated copper plates. The copper plate layers are electrically insulated by insulating materials, and the conductive layer and the insulating layer are laminated into one whole part through a related thermal lamination process. Its emergence brings many advantages to the design and operation of power systems.
One of the characteristics of laminated busbar is its low inductance. Due to its flat shape, opposite currents flow through adjacent conductive layers, and the magnetic fields they generate cancel each other out, thereby greatly reducing the distributed inductance in the circuit. This feature enables laminated busbar to effectively control system temperature rise during power transmission and distribution, reduce system noise and EMI and RF interference, and extend the service life of electronic components.
Another notable feature is its compact structure, which effectively saves internal installation space. The connecting wire is made into a flat cross-section, which increases the surface area of the conductive layer under the same current cross-section and greatly reduces the spacing between the conductive layers. This not only increases the heat dissipation area, which is beneficial to the increase of its current carrying capacity, but also reduces the damage caused by voltage commutation to phase components, reduces line losses, and greatly improves the maximum current carrying capacity of the line.
In addition, the laminated busbar also has the advantages of high-power modular connection structure components and easy and quick assembly. This makes it more flexible in practical applications and can meet the power transmission and distribution needs in different scenarios.
