Description

Technical Field

[0001] The utility model relates to the field of anti-leakage alarm for optical cables, electrical cables or steel strands, in particular to an outdoor rainproof leakage alarm which can be powered by solar energy. Background Art

[0002] In real life, optical fiber cables for communications are suspended on steel strands or placed in underground pipelines for long-distance transmission. During this process, if optical cables or cables cross or coexist in the same pipeline, the insulation sheathing can age and break over time, allowing leakage current to flow through the broken sheath into the steel strands or cables. Steel strands are conductive because they are metal, and optical cables also have metal reinforcements, which are also conductive. This can cause leakage current in the overhead steel strands, pole guy wires, or optical and electrical cables. This invisible leakage current can easily cause electrocution when construction workers are performing normal work on the cables. Furthermore, because the guy wires on utility poles are fixed to the ground, leakage current can leak to the ground. Especially during rainy days and strong winds, optical and electrical cables often break and sag to the ground. Water on the ground can also conduct electricity, causing step voltage electrocution to passersby. Step voltage shock is caused by a difference in ground potential. It can occur when a person or animal is within 8-10 meters of a high-voltage power line. In this case, the current travels along the lower body, from the feet, through the legs, and around the hips, back to the feet and the ground, forming a path that causes an electric shock.

[0003] In order to save lives and protect people's lives and property safety, we have developed a solar-powered outdoor rainproof leakage alarm to solve the problem of innocent electric shock and protect innocent people or livestock from fatal injuries caused by leakage. Utility Model Content
