Online monitoring device power supply system based on high-voltage transmission line jumper wire energy acquisition

Abstract

The embodiment of the invention discloses an online monitoring device power supply system based on high-voltage transmission line jumper wire energy acquisition. The system is used for solving a technical problem that a method in the prior art for supplying power to an online monitoring device on a high-voltage transmission line is unreliable in power supply and susceptible to random factors such as weather and the like. The system comprises a CT energy acquisition coil, a power converter, a transmitting coil resonator, a receiving coil resonator, a rectifier, a rechargeable battery and an online monitoring device. The CT energy acquisition coil sleeves the transmission line, and is connected with the power converter and the transmitting coil resonator successively. The transmitting coil resonator is horizontally and fixedly arranged above a jumper wire sleeve of the transmission line. The receiving coil resonator is inductively connected with the transmitting coil resonator, is used for receiving the high-frequency energy transmitted by the transmitting coil resonator to an air medium, and is connected with the rectifier, the rechargeable battery, and the online monitoring device successively.

Description

technical field [0001] The invention relates to the technical field of on-line monitoring of high-voltage transmission lines, in particular to an energy supply system for on-line monitoring equipment based on high-voltage transmission line jumper energy harvesting. Background technique [0002] my country's transmission lines have a large geographical span and a wide distribution range, and often pass through some areas with harsh natural conditions. In order to ensure the safe operation of transmission lines, personnel are required to periodically inspect the lines. With the development of technology, online monitoring equipment has been widely used in this field, saving a lot of manpower and material resources. Due to the environmental impact and cost constraints of the high-voltage transmission line itself, it is impossible to change the normal voltage around the high-voltage transmission line. Transformers are used to convert high voltage to low voltage. Therefore, the a...
