A protection device for photovoltaic, internal combustion power generation and energy storage microgrid

Abstract

The invention discloses a protection device for photovoltaic, internal combustion power generation, and energy storage micro-grids. The protection device for photovoltaic micro-grids includes: an installation box for installing components of photovoltaic micro-grids; a drive assembly, The driving assembly is installed on the upper side wall of the installation box, the driving assembly includes a wind wheel and a rotating shaft, the rotating shaft vertically penetrates the upper side wall of the installation box, and the wind wheel is fixedly connected to the At the top of the rotating shaft, the driving assembly is used to provide power for heat dissipation in the installation box; the fixing assembly is installed on both sides of the installation box, and the fixing assembly includes a fixing bar, a gear of the present invention and a transmission The shaft and the transmission wheel fixed on the transmission shaft rotate. Since the transmission wheel on the fixed shaft and the transmission wheel on the transmission shaft are sleeved with a belt, the fixed shaft rotates at the lower end of the fixed bar and drives the cooling blades to rotate. Heat dissipation in the box.

Description

technical field [0001] The invention relates to the technical field of photovoltaic, internal combustion power generation and energy storage microgrids, in particular to a protection device for photovoltaic, internal combustion power generation and energy storage microgrids. Background technique [0002] With the continuous development of technology and industrial technology, the fastest growing part of the global microgrid market is the photovoltaic hybrid microgrid. Photovoltaic is the most commonly used power generation technology for microgrids today. A typical modern microgrid consists of photovoltaic power sources and energy storage systems. , the advantage of photovoltaic energy storage is to increase the self-consumption rate of photovoltaic energy, peak shaving and valley filling, demand management and other advantages. In China, it is facing huge pressure on energy conservation and emission reduction. The decline in the price of photovoltaic energy storage has also ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the following shortcomings in the prior art. Because the existing installation box does not have a heat dissipation structure, it is easy to generate heat in the installation box when the temperature is high, so it is very unfavorable to the environment where the power grid is located. When photovoltaic microgrid components are installed, they are mostly used for screw fixing, so it is very inconvenient to disassemble and install, making it inconvenient to use, and a protective device for photovoltaic, internal combustion power generation and energy storage microgrids is proposed
