Guide: The function of bus bar and bus type, the function of bus is to assemble, distribute and transmit electric energy, bus bar According to the structure is divided into hard bus and soft bus, hard bus is divided into rectangular bus and tubular bus and so on.

The function of Busbar-bus type

In the substation, the connection of all levels of voltage distribution devices, as well as transformers and other electrical equipment and the corresponding distribution device connection, mostly using a rectangular or circular cross-section of bare conductors or stranded wire, which is collectively referred to as Busbar.

1, the function of Busbar

The function of Busbar is to collect, distribute and transmit electric energy. Because of the bus in operation, there is huge power through, short-circuit, bear a lot of heat and electric power effect.

Therefore, it is necessary to choose the bus material, section shape and sectional area reasonably to meet the requirements of safe and economical operation.

2, the type of Busbar

Bus Bar According to the structure is divided into hard bus and soft bus. The hard bus is divided into rectangular bus and tubular bus.

Rectangular busbar is generally used in the main transformer to the Power distribution room, the advantages of the construction and installation of convenient, small changes in operation, large load flow, but the cost is higher.

The soft bus is used outdoors, because the space is big, the conductor swings also not to cause the line between distance not enough. Soft bus construction is simple and low cost.

In the design of the substation, for more than 35kV Busbar, there is a tube-shaped bus made of aluminum alloy material.

This bus structure can reduce the bus-to-phase distance. The knot line is clear, the maintenance quantity is small, but the busbar fixed gold is more complicated.
