Description

Technical Field

[0001] This utility model belongs to the field of busbar technology, specifically a busbar with quick replacement function. Background Technology

[0002] Busbars are electrical devices used for power transmission and distribution, widely used in industrial and commercial buildings, data centers, and other applications. Compared to traditional cables, busbars offer higher current-carrying capacity, flexibility, and reliability.

[0003] Currently, existing busbar trunking systems are generally assembled by directly connecting the core to the outer shell. This means that when the core needs to be inspected, maintained, or replaced, the entire outer shell must be removed before the core can be inspected, maintained, or replaced. This not only results in slow speed and efficiency but also seriously affects the normal operation of the circuit where the busbar trunking is located. In addition, most existing busbar trunking systems do not have the function of directly connecting to supporting components, which means that the busbar trunking cannot be used when tilted or upside down, seriously affecting the applicability of the busbar trunking. Furthermore, the ventilation and heat dissipation of existing busbar trunking systems are also poor, which not only poses certain safety hazards but also seriously affects the reliability and service life. Therefore, it is necessary to design a busbar trunking system with a quick replacement function. Summary of the Invention

[0004] In response to the above situation, to address the issue that existing busbar trunking systems commonly use a direct connection between the core and the outer shell during assembly, which necessitates the complete removal of the outer shell before core maintenance and replacement can be performed, resulting in slow speed and efficiency, and severely impacting the normal operation of the lines connected to the busbar trunking, and because most existing busbar trunking systems lack the capability for direct connection to supporting components, they cannot be used when tilted or inverted, significantly limiting their applicability, and their ventilation and heat dissipation are also poor, posing certain safety risks. The existing problems, such as hidden dangers, seriously affect the reliability and service life of the busbar. This utility model provides a busbar trunking with a quick replacement function, which effectively realizes the function of direct connection with external support components. The connection stability is high and the busbar trunking can still be used under tilted and inverted conditions. It also realizes the function of quick replacement of the core. The direct connection between the core plate and the cover plate means that if the core component needs to be inspected, maintained or replaced, there is no need to disassemble the bottom support plate and the external support components.
