Description

Technical Field

[0001] This utility model relates to the field of cable lightning protection box technology, specifically a cable lightning protection box that integrates lightning protection and surge protection. Background Technology

[0002] A cable surge protector is a device used to protect cables and connected equipment from damage caused by lightning overvoltages, induced overvoltages, operational overvoltages, and electrostatic discharges that travel along the cable lines. For example, a mine explosion-proof cable junction box can protect communication cables and other equipment within a mine.

[0003] When using current cable surge protection boxes, because they are single, integrated surge protection structures, they cannot be disassembled or not installed as needed. Some surge protection boxes are too fragmented, making the connection between components cumbersome and resulting in a messy situation of multiple wire harness connections, which is not conducive to the use of current cable connections. Utility Model Content

The cable extends through the cable tray into the main support box, where the inserted cable ends connect to the main transmission unit. Transmission occurs only when the cable passes through the main transmission unit. A surge protector is fixedly connected to the side of the mounting plate. After the surge protector and main transmission unit are electrically connected, a connecting block is threadedly fixed to the mounting screw hole at the bottom. The bottom end of the mounting screw is then connected to the top of the lightning protection rod. The location forms an electrical connection between them, allowing the bottom surge protector and lightning protection rods to be inserted below the ground to form a grounding effect. In the event of a lightning strike or surge, the surge protector and lightning protection rods can conduct the electricity without affecting the cable. Remote monitoring is possible via an external control panel and mainboard. The internal heat dissipation box provides efficient cooling for the main support box. The modular structure allows for flexible installation, and the combination of lightning and surge protection makes cable transmission safer and more reliable. Attached Figure Description
