Is the high current busbar the core artery of energy transmission?

Publish Time: 2024-07-23
In modern power and energy transmission systems, the high current busbar is regarded as the core artery for connecting and transmitting electric energy. Especially in new energy vehicle power systems and other high-power applications, the role of the high current busbar is crucial. Its main function is to transmit large currents efficiently and reliably while maintaining the safety and stability of the system. As components of key circuits, hard busbars and soft busbars provide solutions of various shapes and structures for current transmission, while the diverse connection methods of the connecting columns ensure their stable and reliable operation.

Application of hard busbars and soft busbars

Hard busbars are usually made of metal sheets (such as copper or aluminum) and have excellent electrical conductivity and mechanical strength. Hard busbars are suitable for occasions that need to carry large currents, such as high-voltage substations, large industrial equipment, etc. Its advantages include:

High conductivity: Hard busbars can effectively reduce resistance losses and ensure efficient transmission of electric energy.

High temperature and high pressure resistance: Hard busbars usually have good high temperature and high pressure resistance, suitable for use in harsh environments.

Structural stability: The structure of the hard busbar is relatively rigid and can provide a stable current channel under fixed installation.

The soft busbar is made of conductive rubber, soft copper strip or other flexible materials, and has excellent flexibility and adaptability. Soft busbars are suitable for application scenarios that require frequent movement or wiring in a small space, such as new energy vehicle power systems, motorized equipment, etc. Its advantages include:

Strong flexibility: The soft busbar can adapt to complex wiring environments, especially for applications that require dynamic movement or small space.

Easy installation: The flexibility of the soft busbar makes installation and maintenance easier and faster.

Shock absorption effect: The soft busbar can effectively absorb vibration and reduce the mechanical stress of the cable during operation.

Connection method of connecting column

In order to ensure the stability and safety of the busbar system, the connection method of the connecting column is crucial. Common connection methods include:

Welding: Welding is the process of connecting the two metal parts of the busbar connecting column by melting metal. Welding connections usually have high strength and good conductivity, which are suitable for the high reliability requirements of high current busbar systems.

Riveting: Riveting is the process of fixing busbar connection posts together by using rivets. Riveting is simple and reliable, and is suitable for applications that require quick installation and removal. Riveted connections usually have good mechanical strength and stability.

Crimping: Crimping is a connection method that crimps the connection post and busbar material together by mechanical pressure. This method can provide a stable connection and has good electrical contact performance. Crimping is suitable for power systems that require high-frequency replacement or maintenance.

As the core artery of energy transmission, the quality of its design and manufacturing directly affects the efficiency and safety of the entire power system. Hard busbars and soft busbars provide flexible options to meet the needs of different application scenarios. A variety of connection methods for connection posts, such as welding, riveting and crimping, ensure the stability and reliability of the busbar system. By optimizing these key components, efficient and reliable power transmission solutions can be provided for high-current and new energy vehicle power systems, thereby promoting the efficient operation and development of modern energy systems.
