In the field of electricity, bus bars can also be called bus bars, bus bars, etc. Most of them refer to bus bars or power supply trunk lines in high and low voltage cabinets, which are used to connect multiple electrical lines. The system will install various interface cards through the busbar, and transmit various data to the equipment connected by the interface card. The bus can serve multiple components. The basic working mode of the bus is usually that the component that sends the information sends the information to the bus in a time-sharing manner, and then the bus sends the information to each component that receives the information at the same time. The device given by the CPU The address is determined by decoding the control signal generated.
Busway is a trunk-type tappable power supply system with large current, most of which refer to dense busway or closed busway, usually composed of metal shell (iron or aluminum), conductor (copper or aluminum row) , insulating materials and related accessories. The inner copper bars are close together, and can be operated safely and stably through insulation treatment. The busway was originally born in the United States, and began to be put into practical application in Japan, and then became popular in developed countries and regions. In recent years, with the large-scale construction of infrastructure, people's demand for electricity is also increasing, and the bus duct has gradually become a high-current transmission system in industrial plants, high-rise buildings, commercial complexes and rail transit. Must-have product.
In fact, the bus bridge has the same function as the bus duct, and it is the operation carrier of high current. It is a busbar system composed of metal plates (steel or aluminum plates) as protective shells, conductive strips, insulating materials and related accessories. It can be made into a plug-in closed busway with spaced junction boxes, or it can be made into a feeder closed busway without a junction box in the middle. There is a gap between the conductive copper bars of the product, which is mainly insulated by the air in the slot. Therefore, the bus bridge is also called an air-type busway.
