A self-supplied energy acquisition device for a transmission line and a multi-dimensional state monitoring method thereof

Abstract

The invention discloses a self-energy-supply type energy harvesting device for a transmission line and a multi-dimensional state monitoring method thereof. The energy harvesting device is installed on the high-voltage side of the power transmission line, and includes an energy harvesting device body and an energy harvesting body monitoring device. The energy harvesting device body is ring-shaped The magnetic core continuously supplies energy to the energy harvesting body monitoring device by collecting the electromagnetic energy of the transmission line. The energy harvesting body monitoring device is installed on the energy harvesting device body and is used to monitor the operating status of the energy harvesting device body. The monitoring method adopts circuit control-start measures according to the fluctuation of the sensitive parameters of the energy harvesting device body, and adjusts or cuts off the energy harvesting device body and the receiving device. The connection of the energy terminal, the energy harvesting body monitoring device will also upload the running status of the energy harvesting device body to the monitoring terminal. The invention fills in the gaps in the state self-awareness technology and remote data transmission technology shortage of existing transmission line induction energy harvesting devices, and provides technical support such as information collection, state perception and equipment evaluation for the construction of the intelligent interconnection era, and has good economical efficiency and practicality.

Problems solved by technology

[0002] The traditional energy supply method of intelligent sensing components of transmission lines mainly completes energy supply through UPS or batteries. At the same time, natural environment energy acquisition and artificial energy supply also have constraints such as geographical environment, manufacturing cost, operation and maintenance, and energy sources, making it difficult to popularize on a large scale. Due to its stability and low cost, line electric field induction energy harvesting is a more suitable energy supply method, but most of the energy harvesting devices are installed on unattended overhead lines, and the harshness of the field and high-altitude environment has increased manual patrolling. As the energy supply end of the line sensor network, the monitoring of the operating status of the sensor energy harvesting device itself is particularly urgent and necessary.
