Lightning conductor high-voltage power-obtaining system and power-obtaining method

Abstract

The invention provides a lightning conductor high-voltage power-obtaining system and a power-obtaining method, wherein the power is uninterruptedly obtained from a high-voltage line to power up power equipment on the power transmission line. The lightning conductor high-voltage power-obtaining system comprises a first tower pole and a second power pole, wherein the spacing between the two power poles is 2.5-3.5 km. The first tower pole and the second power pole are connected with a first ground wire and a second ground wire. A gap insulator is arranged between the first ground wire and the first and second tower poles. The first ground wire is connected with the second tower pole via a first grounding drainage thread. The first tower pole, the first ground wire, the second tower pole and the second ground wire together form a loop. An electromagnetic induction power-obtaining supply is arranged in the loop. According to the technical scheme of the invention, the power is obtained from a lightning conductor by the electromagnetic induction power-obtaining supply, so that the system is free from being influenced by the weather and the temperature. By means of the system, the all-weather, stable and reliable uninterrupted power supply is realized under various harsh weathers and in different working environments. Meanwhile, the system is maintenance-free for a long period of time and can overcome the defects of solar power supply mode and the like.

Description

technical field [0001] The invention relates to a high-voltage line power-taking device, in particular to a system for taking power from a high-voltage line lightning protection line. Background technique [0002] With the rapid development of the national economy, all walks of life have an increasing demand for power, and the requirements for power quality (such as stability and uninterrupted) are also getting higher and higher. Therefore, the safety and stability of new high-voltage transmission lines and supporting equipment, which are the lifelines of power systems, are particularly important. As the complexity of the transmission system increases and the number of protection and monitoring devices increases, the demand for DC power in the middle of the line increases. [0003] The voltage level requirements of this type of power supply are not high, but the requirements for uninterrupted power supply reliability are relatively high. At present, most of the power suppl...

AI Technical Summary

Problems solved by technology

Due to the limitation of energy conversion efficiency, climate environment and cost, solar power supply cannot fully meet the equipment's requirements for all-weather and long-term stable performance, so batteries have to be added to store electric energy

However, because the life of the battery itself is generally only 2 to 3 years, the maintenance cost of the equipment increases, and this power supply method cannot achieve continuous and uninterrupted power supply, so it cannot meet the actual needs, making it difficult to popularize the high-voltage transmission line to realize the online real-time monitoring function.

[0004] In addition, with the development of technology, there are more and more electrical equipment working on high-voltage transmission lines, such as line equipment anti-theft devices, line inspection robots, live working robots, etc., and there are also power supply problems
