Speaking of busbars, I believe many people are very unfamiliar. What is a busbar? what's the effect? In the power system, the busbar connects the current-carrying branches in the power distribution device, and plays the role of collecting, distributing and transmitting electric energy. It is the main line of the power station to transmit electric energy, or the substation.
With the emergence of modern engineering facilities and equipment, the electricity consumption in all walks of life has increased rapidly, especially with the emergence of numerous high-rise buildings and large workshops. Traditional cables as transmission conductors can no longer meet the requirements of high-current transmission systems. The parallel use of multiple cables brings a lot of inconvenience to the on-site installation and construction connection.
The plug-in bus duct emerged as a new type of distribution line. Compared with traditional cables, it fully demonstrates its superiority in large current transmission. At the same time, due to the adoption of new technologies and processes, the busbars are greatly reduced. The contact resistance and temperature rise at the junction of the two ends of the slot and the junction of the branch mouth, the busway adopts high-quality insulating material, so as to improve the safety and reliability of the busway and make the whole system more perfect.
In substations, the connection of voltage distribution devices at all levels, as well as the connection of electrical equipment such as transformers and the corresponding distribution devices, mostly use bare or stranded wires with rectangular or circular cross-sections, which are collectively referred to as bus bars. Bus bars are low impedance conductors that can connect multiple circuits. The busbars are made of highly conductive copper and aluminum materials. It is used to transmit electrical energy. It is a product that collects and distributes electricity. It is the main line for power transmission in power stations or substations. Through it, the electrical energy output by the generator, transformer or rectifier is delivered to various users or other substations.
The function of the bus is to collect, distribute and transmit electrical energy. Due to the large amount of electrical energy passing through the bus during operation, it will suffer great heating and electrodynamic effects during short circuit. Therefore, the material, cross-sectional shape and cross-sectional area of the busbar should be reasonably selected to meet the requirements of safe and economical operation.
