Description

Technical Field

[0001] The utility model relates to the technical field of lightning arresters, and more specifically, to a lightning arrester installation structure for a transformer substation. Background Art

[0002] Substation refers to the place in the power system where voltage and current are transformed, electric energy is received and distributed. There are a large number of electrical equipment in the substation. In order to avoid damage to the electrical equipment due to lightning strikes in thunderstorms, lightning arresters need to be installed in the substation. Lightning arresters can protect electrical equipment from high transient overvoltage hazards. At present, when lightning arresters are installed on substations, they are fixed on the substations by bolts. However, due to the long length of the lightning arrester, when encountering severe weather and strong crosswinds, the lightning arrester will shake left and right, causing the lightning arrester to break and affecting its use.

[0003] After searching, a Chinese patent with publication number CN220553807U discloses a substation arrester installation structure. When installing the arrester, the arrester can be supported by the installation support assembly. When strong crosswinds are required, the arrester will not shake or break, thereby solving the above-mentioned problem.

[0004] However, in actual use, the above-mentioned lightning arrester installation structure basically adopts a rigid connection structure. For the rigid connection support, although the support structure has high strength, it is too rigid and easy to break. When it is blown by strong wind without a buffer structure, it will also break. Therefore, it is necessary to design a lightning arrester installation structure with a buffer structure. Utility Model Content

[0013] Beneficial effects of the utility model:

[0014] 1. The substation arrester is convenient to assemble and disassemble. By setting a transverse buffer component, it is convenient to play a buffering role when the substation arrester is subjected to a force in the corresponding direction during use. During the buffering process, the substation arrester is driven by the wind to move the connecting frame at the bottom, thereby moving the movable seat at the bottom. The movable seat will drive the telescopic plate to move during the movement. When the telescopic plate moves, it drives the second movable plate to move.

During the buffering process, the mounting frame first tilts to exert a flipping force on the arc plate. Since the arc center positions of the arc seat and the arc plate are set according to the shaft position at the top of the rotating base, the arc plate can be kept stably moving inside the arc seat, thereby driving the first movable plate to move stably on the inner wall of the arc groove, and driving the first spring to compress, thereby achieving a buffering effect.
