Description

Technical Field

[0001] This utility model relates to the field of line safety protection technology, specifically to a lightning protection device for power transmission and distribution lines. Background Technology

[0002] With the rapid development of my country's national economy and the widespread application of intelligent devices and electronic information systems, the prevention of lightning disasters is becoming increasingly stringent. Lightning disasters often cause extremely serious consequences for such places. In order to minimize lightning disasters, we must enhance our awareness of lightning protection and disaster reduction. The safety inspection of lightning protection devices deserves our special attention. The main feature of existing lightning protection devices is that lightning rods are installed at the top of existing cement power poles, and metal conductors are installed on the outside of the cement power poles. One end of the metal conductor is connected to the lightning rod, and the other end is connected to a metal rod buried in the ground.

[0003] When installing lightning protection devices on existing power transmission and distribution lines, the conductors are usually installed through PVC conduits. However, the upper part of the PVC conduit is usually exposed, and floating debris can enter the PVC conduit and cause blockage, thus affecting normal use. Furthermore, the crossarm for installing the lightning arrester is usually installed between two separate clamps. When the clamps are damaged, the lightning arrester will immediately tilt or fall, resulting in poor stability.

[0004] Therefore, a lightning protection device for power transmission and distribution lines is proposed. Utility Model Content

However, the upper part of the PVC conduits is often exposed, allowing floating debris to enter and cause blockages, thus affecting normal use. Furthermore, the crossarms for installing surge arresters are usually installed between two separate clamps. When the clamps are damaged, the surge arrester will immediately tilt or fall, resulting in poor stability. This utility model provides a lightning protection device for power transmission and distribution lines.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0010] Furthermore, the protective device includes a PVC guide pipe and a fixing plate. The PVC guide pipe is fixedly installed in the fixing hole of the crossarm, and the fixing plate is fixedly installed on the right side wall of the clamp.

[0011] Furthermore, the protective device includes a PVC protective box and a PVC sealing plate, the PVC guide pipe is fixedly installed on the front side wall of the crossarm, and the PVC sealing plate is installed on the front side wall of the PVC guide pipe.

[0012] Furthermore, the support device includes a fixed seat, an adjusting seat, a connecting block, a fixed block, and a PVC connecting rod. The fixed seat is fixedly installed on the front side wall of the clamp two. The adjusting seat is fixedly installed on the upper end face of the fixed seat. The connecting block is rotatably installed inside the adjusting seat. The fixed block is fixedly installed on the front side wall of the crossbeam. The PVC connecting rod is fixedly installed on the upper end face of the connecting block. The PVC connecting rod is fixedly connected to the fixed block.

[0013] The beneficial effects of this utility model are as follows:

[0014] The lightning arrester is fixed to the utility pole by a fixing device, thus providing stable support for the lightning protection device and the support device. When installing the lightning arrester, the lead wire needs to be connected to its lightning protection end and passed through the guide end of the protective device before being connected to the flat iron and the grounding electrode, thereby achieving the purpose of lightning protection for the power transmission and distribution line. The support device provides support for the lightning arrester, and when a single fixing device on one side is damaged, it can be supported by the support device to prevent the lightning arrester from falling down immediately. When maintenance personnel inspect and repair it, the stability of the lightning arrester during long-term use is improved, thereby reducing the workload of power maintenance personnel.

[0015] The wire enters the PVC guide tube through the wire hole on the right side wall. The entrance of the PVC guide tube is protected by a PVC protective box and a PVC sealing plate to prevent floating debris from entering the PVC guide tube and causing blockage during long-term use, thus affecting normal use.
