Description

Technical Field

[0001] The utility model relates to the field of busbars, and more specifically, to an adjustable busbar supporting structure. Background Art

[0002] Busbar is a connecting conductor used to collect, distribute and transmit electric energy. With the rapid development of the power industry, power plants, substations and various power facilities have an increasing reliance on busbars. In power transmission and distribution systems, busbars play a vital role.

[0003] The busbar is often supported by a bus duct during daily use. In order to prevent the busbar from being separated from the bus duct due to vibration, a sealing plate is generally fixed on the bus duct by screws. This results in the need to remove the screws to take out the busbar during maintenance, which is more troublesome. At the same time, in order to reduce the risk of poor contact, arcing or other electrical failures caused by loose busbars, the busbar is generally properly tightened. However, the position of the traditional bus duct is fixed and cannot be adjusted (adjusted according to different busbars), so it is less practical. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide an adjustable busbar support structure.

[0009] Preferably, the fixing structure includes a plurality of screw holes arranged vertically at equal distances on the side ends of the rectangular rod, and a through hole on the side ends of the through slot block. The screws are passed through the through holes and then rotated clockwise to be installed in the screw holes of corresponding heights to complete the fixation between the through slot block and the rectangular rod. The through slot block is fixed at different heights corresponding to the rectangular rod through the fixing structure.

[0010] Preferably, an elastic limiting component is installed between the platform and the top plate to limit the two when the busbar limiting slot seat is close to the top plate.

[0011] Preferably, the elastic limiting component includes a hollow plug block fixed to the front side end of the platform through a connecting plate A, and a groove seat fixed to the top of the top plate through a connecting plate B, movable plates are provided on both sides of the interior of the hollow plug block, a rectangular fixed block is fixedly connected to the surface of the movable plate, guide rails B are fixedly connected to both sides of the interior of the hollow plug block, both sides of the movable plate are slidably connected in the guide rails B through a slider B, springs are fixedly connected between the movable plates, and rectangular through grooves for inserting the rectangular fixed blocks are provided on both sides of the groove seat to prevent the lifting assembly from being affected by vibration, causing the connection between the top plate and the busbar limiting groove seat to loosen.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model adjusts the height of the top plate through a sliding connection assembly. When the height adjustment is completed, the busbars are placed one by one in the busbar limit slot seat, and the lifting assembly drives the platform to move upward, thereby driving the upward movement of multiple busbar limit slot seats, so that the lifting assembly tightens the busbar upward. After tightening, the limit slot seat just contacts the bottom of the top plate, thereby closing its top. The lifting assembly drives the platform to move downward, and the top of the limit slot seat can be opened to take out the busbar. In this way, the top of the limit slot seat can be closed and the busbar can be taken out conveniently. At the same time, the lifting assembly and the sliding connection assembly can be adjusted according to different busbars as needed, so that the busbar is tightened, thereby solving the problem that the busbar in the background technology needs to be removed by removing the screws when it is repaired, which is relatively troublesome. And the position of the busbar slot is fixed and cannot be adjusted, and the practicality is low.

[0014] 2. In the utility model, when the top plate and the busbar limiting groove seat on the platform are tightly attached, the hollow plug block is also inserted into the groove seat. Before the insertion, the rectangular fixed blocks on both sides of the hollow plug block can be pressed into the hollow plug block, thereby driving the two movable plates to move to the middle part, and the movable plate drives the movement of the slider B, and the slider B slides along the guide rail B to maintain the linear movement of the movable plate and the rectangular fixed block, and at the same time squeezes the spring between the two movable plates. After the hollow plug block is fully inserted, the rectangular fixed blocks on both sides are no longer blocked, and the spring begins to extend in the opposite direction, thereby resetting the rectangular fixed block, so that the rectangular fixed block passes through the rectangular through grooves on both sides of the groove seat, thereby fixing the hollow plug block in the groove seat, so as to fix the top plate and the busbar limiting groove seat, and prevent the lifting assembly from being affected by vibration, which causes the connection between the top plate and the busbar limiting groove seat to loosen.
