Problems solved by technology

[0003] There are some deficiencies in the existing double-split photovoltaic transformers: the current photovoltaic transformer structure in the industry is a double-split photovoltaic transformer structure, which includes two sets of axially split low-voltage coils, and two sets of axially split and low-voltage coils one by one. Corresponding high-voltage coils and iron cores, two sets of high-voltage coils are arranged axially. When pouring, two sets of high-voltage coils are poured into one coil. Electrically, the two sets of coils are connected in parallel and then lead out uniformly. This structure is used in conventional 10KV products. , due to the low voltage level, the two sets of high-voltage coil

Description

technical field [0001] The invention relates to the field of transformers, in particular to a double-split photovoltaic transformer structure. Background technique [0002] With the reduction of global energy reserves and the enhancement of human awareness of environmental protection, the scale of the photovoltaic power generation industry is gradually expanding, the technology is gradually improving, the cost of photovoltaic power generation is gradually decreasing, and the future photovoltaic capacity will also increase significantly. The United States proposed the "Solar Pioneer Plan" to reduce the cost of solar photovoltaic power generation so that it can reach the level of commercial competition in 2015; Japan also proposed to reach a total photovoltaic power generation capacity of 28GW in 2020. Under the background of developing a low-carbon economy, governments of various countries have gradually increased their recognition of photovoltaic power generation. [0003] ...
