Bus duct head-end box
By independently setting the secondary circuit assembly on the main circuit assembly's starting box within the busbar trunking's starting box, and isolating it from the main circuit via a flange unit, the problems of limited installation methods and inconvenient maintenance in existing technologies are solved, achieving both circuit safety and reliability as well as convenient maintenance.

AI Technical Summary
The existing busbar trunking start box cannot support both horizontal and vertical installation at the same time. The main circuit and secondary circuit components share the same box, which leads to electromagnetic interference and unstable communication signals. The main circuit heats up, affecting the lifespan of the secondary circuit. Furthermore, inspection and maintenance are inconvenient, as the main circuit must be disconnected before they can be carried out.
Design a busbar trunking start box, in which the secondary circuit assembly is independently set on the start box shell of the main circuit assembly, isolated from the main circuit by a flange unit, and supports horizontal or vertical installation. The use of a hoisting structure and sealing components improves installation adaptability and safety.
It achieves full physical isolation between the main circuit and the secondary circuit, reduces electromagnetic interference, ensures that communication is not affected during maintenance, supports maintenance of the secondary circuit without interrupting the power supply to the main circuit, improves the convenience and safety of maintenance, and meets the power requirements of the data center.
