Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, and in particular to an intelligent bus duct. Background Art

[0002] Modern high-rise buildings and large workshops require huge amounts of electrical energy. In the face of this huge load, which requires hundreds or thousands of amperes of strong current, it is necessary to use safe and reliable conduction equipment. The bus duct system is a good choice. The bus duct system is a power distribution device that efficiently transmits current. The bus duct occupies a small space and is easy to install, making it more and more applicable.

[0003] A Chinese patent discloses a dense bus duct (authorization announcement number CN20564670U). The patented technology can provide the waterproof bus duct with at least one guide surface on the upper end surface of the shell, the height of the guide surface gradually decreases toward its center position, and an upper guide hole is provided at the center position of the guide surface, and a lower guide hole corresponding to the upper guide hole is provided on the lower end surface of the shell. However, this waterproof bus duct discharges the accumulated water by guiding the water to the guide hole at the center position of the guide surface. However, the structure of the bus duct is relatively complex, the processing cost is high, and the existing bus duct often cannot meet the current carrying capacity requirements of national and international standards. The current passing through the bus duct during use ranges from hundreds of amperes to thousands of amperes. As long as aging and other reasons occur in a certain link, the resistance at the connection of the bus duct will increase, which will directly cause the temperature rise of the contact point to increase. Once the temperature rise exceeds the specified value, it is easy to cause a fire. It is necessary to grasp the temperature in the bus duct in real time.

[0004] Therefore, those skilled in the art provide a smart bus duct to solve the problems raised in the above background technology. Utility Model Content
