Description

Technical Field

[0001] The utility model relates to the field of photovoltaic inverter protection, in particular to a rain shelter for an inverter. Background Art

[0002] The power generation characteristics of distributed power sources are different from traditional power generation. As the proportion of distributed energy in the distribution network continues to rise, the operation mode of the traditional distribution network has changed, changing the distribution network from a simple radial network with a single power source to a complex network with multiple power sources, causing great changes in the network structure and flow direction, and also allowing the inverters in traditional large-scale projects to be used in households. There are still certain defects in the waterproof installation of inverters in the existing technology.

[0003] A Chinese invention with application number CN202211650290.5 in the prior art discloses an outdoor waterproof distribution cabinet. On rainy days, a connecting plate drives a plug-in rod to seal the heat dissipation holes to prevent rainwater from entering the distribution cabinet, which has a waterproof effect to a certain extent; but there are still defects in the specific use process. The plug-in rod blocks the heat dissipation holes, resulting in the heat inside the cabinet cannot be discharged, causing the temperature inside the cabinet to rise too quickly, affecting the working performance of various electrical components in the cabinet, and causing a fire in severe cases; and when the amount of rain is too large, the gathering of rainwater will still cause the bottom of the distribution cabinet body to be soaked in water, and the waterproof effect is not very good.
