Description

Technical Field

[0001] This utility model relates to the field of lightning protection equipment technology, specifically to an adjustable power grid node lightning protection device connection structure. Background Technology

[0002] A node in a power grid refers to a critical point connecting multiple circuits or devices. It plays a vital role in connecting, distributing, and converting electrical energy in the distribution network, and is crucial for ensuring the stable operation of the power grid. These nodes can be electrical equipment such as transformers, switchgear, and busbars, or they can be junctions within the power grid. During the use of power grid nodes, the installation and use of lightning protection devices are of great significance for ensuring the safe operation of the power system; and the lightning protection devices require connecting structures such as brackets for installation between them and the power grid nodes.

[0003] Utility model patent CN221380466U discloses a lightning arrester bracket for a station building. The bracket includes a mounting plate, with a mounting bracket slidably connected to one side of the mounting plate. A lightning arrester is mounted on one side of the mounting bracket, and a base plate is fixedly mounted on the bottom of the mounting plate. A stabilizing mechanism is provided on one side of the mounting plate, comprising a locking plate, locking holes, a telescopic rod, and a fixing plate. Two fixing plates are fixedly mounted on one side of the mounting plate, and telescopic rods are fixedly mounted on the sides of the two fixing plates that are close to each other. A locking plate is fixedly mounted on the bottom of the mounting bracket, and both locking plates have locking holes that match the telescopic rods. Moving the mounting bracket causes the locking plate to move downwards, compressing the telescopic rod. This compresses a spring through a circular plate. When the telescopic rod matches the locking hole, the potential energy of the spring causes the telescopic rod to move towards the locking hole and engage with it. The locking plate stabilizes the mounting bracket, preventing it from tilting and thus providing better stability.

[0004] Although the surge arrester bracket of this station building has the advantage of convenient installation, the device still has the following problems in actual use: In the actual use environment of the surge arrester, the installation of the surge arrester may cause unnecessary interference with other equipment or structures. When the surge arrester is installed by the mounting bracket, the height of the surge arrester cannot be adjusted, so it is difficult to avoid unnecessary interference with other equipment or structures, which has great limitations. In view of this, we propose an adjustable grid node surge protection device connection structure. Utility Model Content

[0005] To address the aforementioned challenges, this invention provides an adjustable connection structure for a power grid node lightning protection device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An adjustable power grid node lightning protection device connection structure includes a surge arrester, with a connection part provided on the front side of the surge arrester.

[0008] The connecting part includes a base with a strip groove. A double-ended lead screw is rotatably installed in the strip groove.

[0016] Furthermore, the slider and the fixing rod are integrally formed structures, and both the slider and the fixing rod are made of stainless steel.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] The design incorporates two interconnecting parts: Firstly, rotating the double-ended screw causes the two support plates to move synchronously relative to each other. The support plates then drive the top seat to rise and fall, which in turn drives the support and surge arrester to rise and fall, facilitating the adjustment of the surge arrester's height. This height adjustment prevents unnecessary interference between the surge arrester and other equipment or structures. This design not only enhances the installation flexibility and adaptability of the surge arrester but also effectively reduces safety hazards caused by improper installation, providing a more solid guarantee for the safe and stable operation of the power grid nodes. Secondly, a detachable connection structure is provided between the support and the top seat. This design improves the ease of assembly and disassembly between the support and the top seat, thereby enhancing the ease of assembly and disassembly of the surge arrester. This design also improves the convenience of subsequent maintenance of the surge arrester. Attached Figure Description
