Intelligent solar photovoltaic box-type substation

Abstract

The invention relates to the technical field of photovoltaic box-type substations, in particular to an intelligent solar photovoltaic box-type substation. The substation comprises a box body, a first mounting cavity, a second mounting cavity, a cooling cavity, heat dissipation holes, a protective door and a heat dissipation assembly; the first mounting cavity, the cooling cavity and the second mounting cavity are sequentially arranged in the box body from left to right; protective doors are hinged to the positions, corresponding to the first mounting cavity and the second mounting cavity, of the outer surface of the front end of the box body; the cooling cavity is formed in the position, located between the first mounting cavity and the second mounting cavity, in the box body, and heat dissipation holes are formed in the positions, close to the upper ends, of the inner walls of the sides, away from the cooling cavity, of the first mounting cavity and the second mounting cavity. According to the invention, by arranging the heat dissipation assembly, rainwater can be collected through the cooling cavity, water-cooling heat exchange can be carried out on the interiors of the first mounting cavity and the second mounting cavity by utilizing the rainwater in the cooling cavity, and heat dissipation blades arranged in heat dissipation holes can be rotated in the rainwater collection process.

Description

technical field [0001] The invention relates to the technical field of photovoltaic box-type substations, in particular to an intelligent solar photovoltaic box-type substation. Background technique [0002] Box-type substation, also known as prefabricated substation or prefabricated substation, is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device, which are prefabricated indoor and outdoor compact in a factory according to a certain wiring scheme. Power distribution equipment, which organically combines functions such as transformer step-down and low-voltage power distribution, is installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulated, fully enclosed, and movable steel structure. [0003] The existing patent (notification number: CN109616909B) is an intelligent solar photovoltaic box-type substation, including a box-type substation shell, high-voltage components, voltage...

AI Technical Summary

Problems solved by technology

Photovoltaic box-type substations are compact in structure, so heat dissipation conditions are particularly important. With the continuous expansion of urban areas, the power load in urban areas increases, and the burden on substations is also increasing. The problem of heat dissipation in substations becomes more prominent. Guarantee the normal operation of the equipment, and even destroy the safety and stability of the power grid, causing great economic losses. The existing photovoltaic box-type substation usually uses heat dissipation holes to dissipate heat inside the box, but this method does not have a good heat dissipation effect and cannot be fast and effective. It can dissipate heat inside the box, and rainwater will enter the inside of the box through the cooling holes during use, especially in rainy areas, where rainwater entering the box for a long time will affect its internal components
