Description

Technical Field

[0001] The utility model relates to the technical field of transformer manufacturing, and specifically to an integrated new energy substation. Background Art

[0002] As global energy consumption increases dramatically, the consumption of traditional resources such as coal, oil, and natural gas accelerates. Wind and solar energy, as an inexhaustible clean energy, are developing rapidly. The booming wind power generation and solar photovoltaic power generation markets have driven the rapid development of the new energy box-type substation market.

[0003] The box-type substations for new energy power generation mainly include four types: combined transformers, prefabricated substations, compact prefabricated substations and container prefabricated substations. In new energy power generation projects, combined transformers have the highest utilization rate due to their simple structure and diversity, and high cost performance. New energy power generation converts solar energy or wind energy into electrical energy through photovoltaic panels or wind power generators, outputs direct current, and does not pass through the battery energy storage link in the middle. After passing through the inverter, it outputs alternating current, and then is connected to the power grid after being stepped up by the step-up transformer in the substation. The structure of our company's previous photovoltaic substation products was divided into four equal grids, that is, the transformer was surrounded in both directions, and the heat dissipation effect was affected; in addition, there were multiple inclined surfaces on the top cover 1-2, and the process was relatively complicated, and it was easy to cause water accumulation at the location where the transformer was installed, posing a safety hazard. In actual use, the product is also prone to damage, such as structural damage, rain short circuit, and dust pollution; the unreasonable layout of internal components and heat dissipation structure can easily cause excessive temperature rise, affecting the efficiency and service life of the entire substation; in addition, the substation is large in size, which is not conducive to transportation and transfer, and the installation efficiency is slow; in view of the above problems of connecting the transformer 3 through the low-voltage terminal 1-9 on the side wall of the low-voltage incoming line area 1-4, it is necessary to improve the existing equipment.
