Embodiment Construction

[0030] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to an overwater photovoltaic substation, which comprises a substation box body, an oil-immersed transformer, an oil collecting device and a drainage device. The substation box body comprises a top plate, a bottom plate opposite to the top plate, and side plates connecting the top plate and the bottom plate. A containing cavity is defined by the bottom plate, the top plate andthe side plates. The oil-immersed transformer and the oil collecting device are both contained and installed in the containing cavity. And the oil collecting device is positioned between the oil-immersed transformer and the bottom plate. An oil collecting groove is formed in the end, facing the oil-immersed transformer, of the oil collecting device. And the drainage device is arranged outside thesubstation box body. The drainage device comprises a shell, an oil-water separator and an oil stain adsorption piece. The shell is provided with an oil removing cavity and a water collecting cavity which are oppositely arranged in a separated mode and communicate through a mounting hole. The oil-water separator is mounted in the mounting hole. A water outlet communicated with the water collectingcavity is formed in the side wall of the shell. The oil stain adsorption piece is accommodated in the oil removing cavity. The oil removing cavity is communicated with the oil collecting groove. Therefore, due to the arrangement of the oil collecting device and the drainage device, the overwater photovoltaic substation is more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of new energy floating photovoltaic power generation, in particular to a floating photovoltaic substation. Background technique [0002] Photovoltaic power generation, as an emerging power generation mode, is generally applied in areas with rich sunlight resources, usually including mountainous photovoltaics, coal mining subsidence area photovoltaics, pond photovoltaics (complementary fishing photovoltaics), water photovoltaics, farmland photovoltaics (agricultural photovoltaics) Complementary) and other terrestrial photovoltaics. [0003] The step-up box transformers used in domestic aquatic photovoltaics are usually American transformers (combined transformers) and small-capacity European transformers (pre-installed substations). Among them, the most commonly used transformers are oil-immersed transformers. [0004] However, since oil-immersed transformers may leak oil due to various reasons during use, a...
