Capacitive energy collecting converting device based on transformer substation field energy

Abstract

The invention discloses a capacitive energy collecting converting device based on transformer substation field energy. The device comprises a capacitive energy collecting converter and an electronic conditioning circuit. The capacitive energy collecting converter comprises an upper pole plate, a lower pole plate and a plurality of insulation supporting columns. The upper pole plate is a semi-sphere shell body. The lower pole plate is a circular flat plate. A semi-sphere shell hollow cavity of the upper pole plate corresponds to the lower pole plate. The semi-sphere shell plane of the upper pole plate is parallel to the lower pole plate. The upper pole plate and the lower pole plate are connected through the three insulation supporting columns. A leading wire is led out from each of the upper pole plate and the lower pole plate and is connected to the electronic conditioning circuit which comprises a rectifying circuit, a storage circuit and a voltage stabilizing feedback circuit which are connected in sequence. The device converts abundant field energy in a transformer substation to electricity energy to be provided for a wireless sensor network, and accordingly the problem of energy feeding of the wireless sensor network is fundamentally solved.

Description

technical field [0001] The invention relates to an energy collection conversion technology applied to a high-voltage substation, in particular to a capacitive energy collection conversion device based on the electric field energy of the substation. Background technique [0002] With the development of society and economy, the problem of energy shortage is becoming more and more serious, and the institutional contradictions are becoming more and more prominent. The electric power industry is also facing profound changes. The smart grid will become the core content of the future development of the electric power industry. The core connotation of the smart grid is to realize the integration of new information and communication technologies in all links of the power system, among which the sensing and measurement technology for real-time monitoring of the system status is the most important technical basis of the smart grid. The real-time monitoring network composed of a large n...

Problems solved by technology

The energy collection conversion technology based on light energy is greatly affected by environmental factors such as time and weather, which limits the use of this technology. Although the electrical equipment in the substation vibrates greatly, the vibration collection device needs to be closely connected with the vibration source. Safety considerations limit its application in substations. Energy collection technologies based on temperature difference and acoustic energy cannot meet the energy supply requirements of wireless sensor networks in substations due to low energy sources.
