[0002] Busbar trays, also known as busbar bridges, are a new type of power distribution conductor. Compared with traditional cables, they fully demonstrate their superiority in high current transmission. At the same time, due to the adoption of new technologies and processes, the contact resistance and temperature rise at the connection points of the two ends of the busbar trunking and the plug-in points of the branch ports are greatly reduced.

[0003] Existing high-voltage busbar bridges typically install high-voltage busbars by placing them in several fixed frames, and then bolting another fixed frame to the top of the fixed frame where the busbar is placed, thus fixing and supporting the busbar. However, this installation method is time-consuming, and when the busbar needs to be disassembled, special tools are required to disassemble the fixed frame. Neither disassembly nor installation is quick and convenient. Therefore, a high-voltage busbar bridge is needed to solve the above problems. Utility Model Content

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a high-voltage busbar bridge, including a cable tray 1. A fixing plate 101 is fixedly connected to the top side of the cable tray 1. The top of the fixing plate 101 has several mounting holes, which facilitate fixing the cable tray 1 to the top of the wall. Several spaced fixing brackets 2 are fixedly connected to the bottom of the cable tray 1. Each fixing bracket 2 has two circular grooves 201 at its top. Each circular groove 201 has a spring-loaded component 3 inside. Each fixing bracket 2 has a fixing bracket 203 at its top. Several placement slots 205 are opened on the side of each fixing bracket 2 and the side of each fixing bracket 203. A high-voltage busbar is placed inside each placement slot 205. A plug box 4 is fixedly connected to the side of each fixing bracket 2. The plug box 4 has a... The mounting slot 401 has a limiting component 6 inside. Each fixing bracket 203 has a fixed plate 5 on its side end. The side end of the plate 5 has a hole 501. Through the cooperation of fixing bracket 2, fixing bracket 203, spring component 3 and limiting component 6, this device can quickly install and connect fixing bracket 2 and fixing bracket 203 together by pressing the fixing bracket 203, so as to quickly fix and support the high voltage busbar. The installation is convenient and saves time and effort. When the high voltage busbar needs to be disassembled, the fixing bracket 203 can be automatically lifted by spring 301 by pulling the pull head 601, so as to quickly disassemble the fixing bracket 203. When disassembling the busbar, there is no need to find special tools to disassemble the fixing bracket 203, which is convenient and saves time and effort.

[0021] As one implementation method in this embodiment, such as Figure 2As shown, the rebound assembly 3 includes a spring 301, which is fixedly connected to the bottom of the inner cavity of the circular groove 201. A circular groove plate 302 is fixedly connected to the top of the spring 301. Several circular rods 204 are fixedly connected to the bottom of each fixing bracket 203. Each circular rod 204 is inserted into each circular groove 201. In practice, each high-voltage busbar is placed in the placement slot 205 at the top of the fixing bracket 201, and then each placement slot 205 at the bottom of the fixing bracket 203 is aligned with each high-voltage busbar. At this time, each circular rod 204 is inserted into each circular groove 201. As the rod moves downward, the circular rod 204 can press against the circular groove plate 302 and move downward. At this time, the circular groove plate 302 presses against the spring 301 and retracts. Then, the insert plate 5 is inserted into the insertion box 4. The insert plate 5 can be fixed by the limiting component 6. When the fixing frame 203 is disassembled, the spring 301 automatically pushes against the circular groove plate 302 and rebounds. The circular groove plate 302 can push against the circular rod 204 and the fixing frame 203 and move upward, so that the insert plate 5 can be easily driven out of the insertion box 4, thus making it easy to disassemble the fixing frame 203. When disassembling the busbar, there is no need to find special tools to disassemble the fixing frame 203, making disassembly convenient and saving more time and effort.

[0022] As one implementation method in this embodiment, such as Figure 3 and Figure 4 As shown, the limiting component 6 includes a pull head 601, a fixing rod 602 fixedly connected to the side end of the pull head 601, the fixing rod 602 being inserted into the mounting groove 401, a connecting plate 603 fixedly connected to the side end of the fixing rod 602, a spring 605 sleeved on the outer end of the fixing rod 602, one end of the spring 605 being fixedly connected to the inner side end of the mounting groove 401, and the other end of the spring 605 being fixedly connected to the side end of the connecting plate 603, an insertion rod 604 fixedly connected to the side end of the connecting plate 603, the insertion rod 604 being inserted into the insertion hole 501, and the top end of the insertion rod 604 being sloped. In practice, when the insertion plate 5 is inserted into the insertion box 4, because the top end of the insertion rod 604 is sloped, it is easy to press the insertion rod 604 towards the mounting groove 401 during the downward movement of the insertion plate 5. At this time, the connecting plate 603 can retract by pressing the second spring 605. The insert plate 5 continues to move down, and the insert rod 604 abuts against the side end of the insert plate 5 until the insert plate 5 is completely inserted into the slot. The insertion hole 501 on the side end of the insert plate 5 is aligned with the position of the insert rod 604. At this time, the second spring 605 pushes against the connecting plate 603 and drives the insert rod 604 to rebound. At this time, the insert rod 604 can be inserted into the insertion hole 501, thereby limiting and fixing the insert plate 5. At this time, the first fixing frame 2 and the second fixing frame 203 are connected together, and the high-voltage busbar is fixed and supported in the first fixing frame 2 and the second fixing frame 203. Therefore, this device can quickly install and connect the first fixing frame 2 and the second fixing frame 203 together by pressing the second fixing frame 203, realizing the quick fixing and support of the high-voltage busbar. The installation is convenient and saves more time and effort.

[0023] Working principle: Each high-voltage busbar is placed in the placement slot 205 at the top of the fixing frame 2. Then, each placement slot 205 at the bottom of the fixing frame 203 is aligned with each high-voltage busbar. At this time, each round rod 204 is inserted into each round slot 201. As the fixing frame 203 moves downward, the round rod 204 can press against the round slot plate 302 and move downward. At this time, the round slot plate 302 presses against the spring 301 and retracts. Then, the insertion plate 5 is inserted into the insertion box 4. Since the top of the insertion rod 604 is sloping, during the downward movement of the insertion plate 5... To facilitate the movement of the insert rod 604 towards the mounting slot 401, the connecting plate 603 can retract by pressing against the second spring 605. The insert plate 5 continues to move downwards, with the insert rod 604 pressing against the side end of the insert plate 5 until the insert plate 5 is fully inserted into the slot. At this point, the insertion hole 501 on the side end of the insert plate 5 is aligned with the position of the insert rod 604. The second spring 605 then pushes against the connecting plate 603, causing the insert rod 604 to spring back. The insert rod 604 can then be inserted into the insertion hole 501, thus limiting and fixing the insert plate 5. At this time, the first fixing bracket 2 and the second fixing bracket 203 are connected. The high-voltage busbar is fixed and supported within the first and second fixing brackets 203. When the high-voltage busbar needs to be disassembled, the pull heads 601 at both ends are pulled simultaneously. The pull heads 601 move the fixing rod 602, connecting plate 603, and plug rod 604. When the plug rod 604 no longer limits the plug hole 501, the first spring 301 automatically rebounds against the circular groove plate 302. The circular groove plate 302 can push against the circular rod 204 and the second fixing bracket 203 to move upward, thereby facilitating the removal of the plug plate 5 from the plug box 4, thus facilitating disassembly and fixing. Frame 203, therefore, this device can quickly connect and install Frame 1 2 and Frame 203 together by pressing Frame 203, realizing the quick fixation and support of the high-voltage busbar. The installation is convenient and saves more time and effort. When the high-voltage busbar needs to be disassembled, Frame 203 can be automatically lifted by Spring 1 301 by pulling the pull head 601, thereby realizing the quick disassembly of Frame 203. There is no need to find special tools to disassemble Frame 203 when disassembling the busbar, making disassembly convenient and saving more time and effort.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
