The connection method of Poured Bus Duct plays a vital role in the reliability and safety of its electrical connection.
Bolt connection is a common connection method. Correct bolt connection can provide a relatively stable mechanical connection. By tightening the bolts, the conductors of the two sections of the bus duct are in close contact to ensure that the current can pass smoothly. If the bolts are tightened properly, good electrical connection can be guaranteed, contact resistance can be reduced, and the problem of heating due to excessive resistance can be avoided. However, if the bolts are loose, poor contact will result, and contact resistance will increase, which will not only cause power loss, but also may increase local temperature and cause safety hazards such as fire. Moreover, during long-term use, the bolts may become loose due to factors such as vibration, so regular inspection and maintenance are required.
The plug-in connection method has a certain convenience. It makes the installation and removal of the bus duct relatively easy, especially when line modification or equipment maintenance is required. A good plug-in design can ensure that there is sufficient contact area and contact pressure between the connectors to achieve reliable electrical connection. However, if the quality of the plug-in connector is poor or the design is unreasonable, the contact may be loose, resulting in increased contact resistance and local heating. In addition, the plug-in connection may become loose or detached when subjected to external force, affecting the reliability of the electrical connection.
Regardless of the connection method, the protection level of the bus duct needs to be considered. A good connection should be able to prevent dust, moisture, etc. from entering the connection part, and avoid insulation degradation and short circuits caused by environmental factors. At the same time, the connection method should also take into account the reliability of grounding to ensure that the fault current can be safely introduced to the ground in a timely manner when an electrical fault occurs. In short, choosing the appropriate poured bus duct connection method and ensuring the quality of its installation and maintenance are crucial to improving the reliability and safety of electrical connections, and can ensure the stable operation and power safety of the bus duct system.
