AI Technical Summary

Technical Problem

Harmonic problems generated during the power generation process of photovoltaic or wind power box-type substations lead to electromagnetic interference, voltage waveform distortion, increased heat generation in lines and transformers, increased line loss and copper loss, and reduced power supply efficiency.

Method used

Air circulation is achieved through the partition and mesh door structure of the ventilation slots, and heat dissipation is achieved by combining the door sealing plate of the louver, air conditioner and fan. Flexible connection and vertically arranged copper busbars are used to reduce heat generation. The magnetic eddy current effect is reduced by the cable through hole design, and the copper busbar connection is optimized to improve the heat dissipation effect.

Benefits of technology

It effectively reduces line loss and copper loss, maintains power supply efficiency, prevents transformer overheating and damage, and achieves efficient heat dissipation in prefabricated substations.

Abstract

This utility model relates to the field of prefabricated substation technology, specifically to a heat dissipation structure for a photovoltaic or wind-powered prefabricated substation. It includes a prefabricated box with a top plate. The box is divided into a transformer compartment, a high-voltage compartment, and a low-voltage compartment. The low-voltage and high-voltage compartments are separated from the transformer compartment by partitions. The low-voltage compartment contains a low-voltage cabinet. Multiple elongated ventilation slots are spaced parallel to each other along the height of the low-voltage cabinet on the upper and lower parts of the partition. Tin plates are installed at the connection holes between the low-voltage cabinet and the transformer copper busbars on the partition. A mesh door separates the front of the transformer compartment from the box door. The beneficial effects of this utility model are: the heat dissipation structure for a photovoltaic or wind-powered prefabricated substation achieves air circulation through the partition with ventilation slots and the mesh door. It also features a box door sealing plate with louvers and ventilation holes, and includes an air conditioner and a fan, providing effective heat dissipation for the box, thereby reducing line loss and copper loss and maintaining power supply efficiency.
