specific Embodiment 1

[0014] Specific embodiment 1: with reference to figure 1 , 2 , a high-voltage power cable anti-theft system, including a power cable and an anti-theft device, the power cable includes a core, an insulating layer, a shielding layer, and a protective layer; the outer core is provided with an insulating layer, a shielding layer, and a protective layer in sequence; the The anti-theft device includes wires, a first DC power supply, a second DC power supply, a first current detection unit, a second current detection unit, a field controller unit, a first wireless communication unit, a second wireless communication unit, and a remote controller unit , an alarm unit, and a display unit; the voltage at both ends of the first DC power supply is equal to the voltage at both ends of the second DC power supply;

[0015] The wire is arranged in the protective layer, and the two ends of the wire are respectively located at the two ends of the anti-theft high-voltage transmission power cable...

specific Embodiment 2

[0017] Specific embodiment 2: the display unit, the alarm unit, the second wireless communication unit and the remote controller unit can be realized by using a smart phone.

[0018] The present invention can realize the principle description of the theft point monitoring: no matter the wire core of the thief steals the power cable, or the protective layer of the stolen power cable (the protective layer includes an insulating layer, a shielding layer and a protective layer), it is necessary to first destroy the protective layer. Destroying the covering will definitely destroy the wires. Since the two ends of the wire are respectively connected to the positive poles of the first DC power supply and the second DC power supply, and the voltages of the first DC power supply and the second DC power supply are equal, no current will be generated in the wire. Once the thief steals the power cable If the wire is cut, the wire will be cut first. The moment the wire is cut with metal sc...

Abstract

The invention discloses a high-voltage power cable antitheft device including a power cable and an antitheft device. The antitheft device includes a wire, a first DC power source, a second DC power source, a first current detection unit, a second current detection unit, a field controller, a wireless communication unit, a far-end controller, and an alarm. The wire is arranged in the protective layer of the power cable. The power cable is equivalent to being grounded when is cut off. According to the resistivity and the diameter of the wire, the detected current and the voltage of the DC powersources, it is easy to calculate the position distance of a cut point. Therefore, the high-voltage power cable antitheft device can not only know the occurrence of theft immediately, but also can calculate the theft location immediately.

Description

technical field [0001] The invention relates to the technical field of electric power auxiliary equipment, in particular to a high-voltage power cable anti-theft system. Background technique [0002] The wire and cable industry is the second largest industry in China after the automobile industry, and the product variety satisfaction rate and domestic market share both exceed 90%. Worldwide, China's wire and cable output has surpassed that of the United States, becoming the world's largest producer of wire and cable. With the rapid development of China's wire and cable industry, the number of new enterprises has been increasing, and the overall technical level of the industry has been greatly improved. With the rapid development of the national economy, the amount and scope of use of power cables as the main artery of the national economy are increasing. Power cables are cables used to transmit and distribute electrical energy. It is often used in urban underground power ...
