[0001] The present application relates to the technical field of connection of electrical equipment in a distribution network, and in particular to a busbar bridge and a method for using the same. Background Art

[0002] In the construction of distribution networks, the connection between electrical equipment often requires the use of busbar bridges. Busbar bridges are devices that efficiently transmit electrical energy. They are used to connect different electrical equipment such as transformers, generators, and switchgear in buildings or industrial facilities. Busbar bridges can provide a safe and reliable way to distribute electricity and are easy to install and maintain.

[0003] Existing busbar bridges are usually designed as closed box structures. Although this design helps protect the internal electrical components from the external environment, it also brings some maintenance challenges. When the electrical components inside the busbar bridge need to be repaired or replaced, part or even all of the structure of the entire busbar bridge must be disassembled first, which not only increases the time cost of maintenance work, but also makes the whole process quite cumbersome and labor-intensive.

[0013] According to a busbar bridge of an embodiment of the present application, the inner cavity of the mother bridge shell is rotatably connected to a running rod, the right side of the mother bridge shell is fixedly connected to an installation box, the right end of the running rod penetrates into the inner cavity of the installation box, the outer surfaces of the running rod and the long rod are respectively connected to two meshing third bevel gears, the left end of the running rod is fixedly connected to a worm gear, the inner cavity of the installation box is rotatably connected to a worm meshing with the worm gear, and the outer surface of the limit plate is fixedly connected to a guide plate in contact with the busbar body.

[0014] The present invention also provides a method for using a busbar bridge, comprising the following steps: S1. When the busbar body in the mother bridge housing is maintained and inspected, the user can manually twist the torsion block, and the rotation of the torsion block will drive the first bevel gear, the threaded rod and the first gear to rotate synchronously. Since the two first gears rotate in opposite directions, the two threaded rods are forced to rotate in opposite directions, exerting power on them; S2, the two threaded rods push the threaded block to move to one side respectively, and as the threaded block moves, the first door panel and the second door panel will be driven synchronously to achieve staggered opening and closing; S3. During the installation of the busbar body, first twist the handle to rotate, provide power to the worm, and use the worm as a power source to drive the running rod to rotate; S4, taking the running rod as the center of the circle, and driving the third bevel gear to rotate under the transmission of the running rod, the power is transmitted to the long rod, and then the pulley and the connecting rod rotate synchronously; S5. The connecting rod drives the two second gears to rotate, and the two second gears respectively drive the corresponding long rod to rotate, forming a pair of long rods rotating in the opposite directions. During this process, the protrusion rotates with the long rod, pushing the push plate to swing around the rotating rod. The push plate acts on the limit plate through the short rod, causing the limit plate and the guide plate to move together. Finally, the guide plate implements precise limit clamping on the busbar body to ensure its stable installation and improve the convenience of use.

[0015] Beneficial effects of the present invention: by setting up the unfolding assembly, the convenience of maintaining and inspecting the busbar and other electrical components installed inside the mother bridge is improved. This design allows the user to open the mother bridge housing by simple manual operation without completely disassembling the entire structure as in the traditional method, thereby greatly reducing maintenance time and labor intensity. The unfolding assembly generally includes components such as a torsion block, a bevel gear, a threaded rod, and a gear. These components work together to enable the first door panel and the second door panel to be smoothly opened and closed in an offset manner, providing an unobstructed working space for maintenance personnel. In addition, the setting of the installation components abandons the traditional bolt installation method and adopts a more efficient clamping limit. By manually twisting the handle, including the worm, worm wheel, running rod, bevel gear, long rod, pulley, connecting rod, gear and push plate, the busbar body can be clamped and positioned quickly and accurately. This method not only simplifies the installation steps, but also ensures stability and safety during the installation process, greatly improves work efficiency and is easy to use.
