Embodiment Construction

[0022] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] In the absence of a local DC power supply, the remote power generation unit converts the incident optical power of the laser into electrical power, which supplies the subsequent circuit to continue to work; when the ambient temperature is normal, the heat collection unit converts the heat generated during the power generation process Evacuation to prevent the temperature of electronic devices from being too high to work normally; when the ambient temperature is low, some devices may be frozen, and the heat collector unit collects the heat generated during the power generation process, and conducts appropriate drainage and protection to ensure a low temperature environme...

Abstract

The invention discloses a light-heat-electricity combination device based on the laser energy supply technology. The device comprises a generating unit, a heat collecting unit and a photoelectric conversion device. The device is characterized in that the generating unit is connected with the heat collecting unit through the photoelectric conversion device. The light-heat-electricity combination device based on the laser energy supply technology solves the problem that a power supply on a high voltage power line cannot continuously work, is low in stability and suffers from electromagnetic interference; a photovoltaic battery is high in conversion efficiency (up to be more than 40%), so that the device is relatively high in temperature characteristic, anti-radiation characteristic and relatively low in generation cost, and as a result, the device can continuously and stably work.

Description

technical field [0001] The invention relates to the field of laser energy supply, in particular to a photo-thermal-electric composite device based on laser energy supply technology. Background technique [0002] The problem of icing on transmission lines has always been a problem affecting the safe and stable operation of power installations in China, and other countries are also facing the same problem. In the spring of 2008, many provinces in central China, east China and southern China suffered from long-term and large-scale freezing disasters. Due to the ice-covered disasters, many power transmission lines were disconnected and collapsed. These accidents have had a major impact on the lives of the masses and caused great losses to social property. Therefore, timely grasp the occurrence and development of icing, and take effective technical measures to prevent accidents such as disconnection and collapse, and ensure the safe and stable operation of the power grid. , beco...
