Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage power transmission lines, in particular to a lightning arrester with a quick disassembly and assembly structure. Background Art

[0002] The electricity generated by the power plant is not only used by people nearby, but also transmitted to faraway places to meet more needs. This electricity cannot be directly transmitted through ordinary wires, but must be transmitted using high-voltage transmission lines. Generally, the transmission voltage below 220 kV is called high-voltage transmission, the transmission voltage between 330 and 765 kV is called ultra-high-voltage transmission, and the transmission voltage above 1000 kV is called ultra-high-voltage transmission. When the electricity is transmitted to the place where it is used, the voltage must be lowered before it can be used.

[0003] When lightning strikes a high-voltage transmission line, two parts of current will be generated. One part of the lightning current passes through the tower and the tower grounding resistance, causing the potential of the tower top to change rapidly. The other part of the current is transmitted to the ground wire through the lightning arrester. The lightning arrester is used to protect electrical equipment from high transient overvoltage hazards during lightning strikes, and to limit the follow-on time, and often also the follow-on amplitude. It is connected between the cable and the ground, usually in parallel with the protected equipment. The lightning arrester can effectively protect communication equipment. Once abnormal voltage occurs, the lightning arrester will act and play a protective role.

[0004] In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. Most lightning arresters on the market are still connected by bolts during installation, but the lightning arresters are easily affected by voltage and burned out. When replacing, the bolts need to be removed one by one, which is inconvenient; 2. When the lightning arresters are activated, they are independent and lack supporting components around them, making them easily affected by wind. Utility Model Content

In order to achieve the above purpose, the present utility model provides the following technical solutions: a lightning arrester with a quick disassembly and assembly structure comprises a fixed frame, the bottom of the upper top plate and the top of the lower top plate of the fixed frame are respectively installed with an upper quick-release assembly and a lower quick-release assembly, a lightning arrester body is installed between the upper quick-release assembly and the lower quick-release assembly, the surface of the fixed frame stand is respectively welded with support assemblies through a mounting frame, the surface of the support assembly is installed with support guard plates, the support guard plates are respectively fitted and connected to the outside of the lightning arrester body, and the upper and lower top plates of the fixed frame are respectively provided with connecting ends.

[0006] The upper quick-release assembly comprises an outer insulating layer and an inner conductive layer. The outer wall of the inner conductive layer is glued and connected to the inner wall of the outer insulating layer. The surface wall of the inner conductive layer is welded with a conducting block.

[0008] Further preferably, the connection end is made of metal, and one side of the connection end is respectively installed and connected with an external connection wire, and the outside of the external connection wire is coated with a rubber layer.

[0009] Further preferably, the lower quick-release assembly is consistent in structure with the upper quick-release assembly, and the upper and lower ends of the arrester body are fitly connected to the interior of the upper quick-release assembly and the lower quick-release assembly, and the outer insulating layer is provided with two groups and forms an opening and closing structure through a hinge, and at the same time, the outer insulating layers are respectively connected by connecting panels and limit blocks opened on their surfaces.

[0010] Further preferably, the conductive blocks are provided with two groups in a ring shape and are respectively fitted between the connecting end and the arrester body, and the arrester body is electrically connected to the connecting ends at upper and lower ends respectively through an upper quick-release assembly and a lower quick-release assembly.

[0012] Further preferably, the base surface of the support assembly is provided with an L-shaped B interface via a mounting frame, and one end of the third connecting rod is snap-fitted to the B interface via an A interface.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] In the utility model, the fixing mode of installing the arrester body by bolts is avoided, and the arrester body is clamped in it by using two sets of upper and lower quick-release components. Since the quick-release components are provided with metal conductive blocks that can be used to transmit current, the current transmission characteristics of the arrester body will not be damaged while achieving rapid installation.

[0015] In the utility model, in order to prevent the equipment from being easily affected by external environmental factors when installed outside, support guard plates are added to clamp at both ends to provide it with a certain degree of support. During subsequent maintenance, inspection or replacement of the arrester body, the support assembly can be used to fold the support guard plates to avoid the problem of limitation. In addition, the spring at the rear end of the third connecting rod is used to automatically reset the connecting rods under the drive of the elastic structure, effectively avoiding the tediousness of manual individual stacking.
