Abstract

The invention provides a power supply system of a low-power consumption online monitoring device combing a highly-efficient supercapacitor. The power supply system comprises an electric energy providing unit, an electric energy conversion device and an electric energy storing device, which are successively electrically connected with each other. The electric energy providing unit is tightly attached to the outer wall of an electric power device. The electric energy storing device is electrically connected with the low-power consumption online monitoring device. The electric power providing unit comprises a metal plate and polycrystalline piezoelectric material plates respectively fixed on two faces of the metal plate. One of the polycrystalline piezoelectric material plates is closely attached to the outer wall of the electric power device. The electric energy storing device is a flat plate-shaped supercapacitor. According to the invention, the power supply system is advantageous in that the power supply system is simple in structure, free from electromagnetic interference, pollution-free and easy to process and microminiaturization of the power supply system is easy to achieve; a stable, reliable and effective power supply source is provided for the low-power consumption online monitoring device; and reliable operation of the low-power consumption online monitoring device on the electric power device is ensured.

Description

technical field [0001] The invention relates to the field of power supply for electric equipment, in particular to a power supply system for low-power on-line monitoring equipment combined with high-efficiency supercapacitors. Background technique [0002] The monitoring of the operating status of power equipment and transmission lines is of great significance to prevent accidents and ensure the safety of power grid operation. The energy supply problem of the online monitoring device has always been one of the key technical problems restricting its function. With the development of sensing technology, most online monitoring devices use low-power online monitoring equipment, such as low-power sensor chips, but the problem of its stable energy supply still needs to be solved. [0003] Existing solutions still adopt the traditional energy supply method, which uses chemical energy batteries as the main energy supply source. Although chemical energy batteries are widely used fo...

Problems solved by technology

Although chemical energy batteries are widely used for their ease of use, more and more shortcomings in the use process have also attracted people's increasing attention. First, chemical energy batteries and their auxiliary devices occupy a considerable part of micro-electromechanical systems. space and weight; second, the production of chemical energy batteries, waste of materials during use, environmental pollution, and difficulty in recycling have become increasingly prominent; third, the service life of chemical energy batteries is short, and as the voltage drops, the performance of the entire system will reduce
