Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet busbar technology, and more specifically to a shockproof and offset-resistant installation structure for power distribution cabinet busbars. Background Technology

[0002] The anti-vibration design of the busbar in the distribution cabinet reduces the impact of earthquakes or mechanical vibrations on the busbar by setting up elastic supports, buffer devices or sliding guide rail structures (such as bidirectional sliding anti-vibration frames) inside the cabinet.

[0003] According to the public announcement number CN207896489U, published on September 21, 2018, a busbar vibration-damping distribution cabinet is disclosed, comprising a cabinet body, a fixed frame inside the cabinet body, a busbar layer on the top of the distribution cabinet body, a vibration-damping structure on the busbar layer, an insulator on the vibration-damping structure, and a busbar mounted on the insulator; the vibration-damping structure includes: a transverse guide rail, which is horizontally fixed to the bottom of the busbar layer parallel to the long side of the cabinet body, and a first slider on the transverse guide rail, which can slide on the transverse guide rail; a longitudinal guide rail on the first slider, which is perpendicular to the transverse guide rail and horizontally arranged, and a second slider on the longitudinal guide rail, which can slide on the longitudinal guide rail; and an insulator mounted on the second slider.

[0004] As can be seen from the aforementioned patents and prior art, when the cabinet shakes or experiences a minor earthquake, the busbar copper plate is directly fixed to the insulating support with bolts. Long-term vibration can easily cause the bolts to loosen and the busbar to shift, leading to poor contact or short circuits. This results in the need to rewire during subsequent maintenance, which is quite troublesome. Utility Model Content

Next, insert the busbar copper plate 22 into the placement slot 15 on the top plate 14. The end of the busbar copper plate 22 will then contact the inclined surface 205 of the slider 204, pushing the slider 204 inward and causing it to slide within the groove 202 on the placement block 201. At this time, the elastic element 203 made of spring material will be stressed, and when the busbar... After the copper plate 22 moves to the top of the placement groove 15, the slider 204 will slide from the side of the busbar copper plate 22 into the slot 23 on the busbar copper plate 22 to fix the busbar copper plate 22.
