Multifunctional integrated photovoltaic box type transformer substation

Abstract

The invention discloses a multifunctional integrated photovoltaic box type transformer substation. The photovoltaic box type transformer substation comprises a high-voltage chamber and a low-voltage chamber, wherein a photovoltaic transformer is arranged between the high-voltage chamber and the low-voltage chamber; a control chamber is arranged on the other side of the low-voltage chamber; the high-voltage chamber, the photovoltaic transformer, the low-voltage chamber and the control chamber are all assembled on a steel structural base; extension mounting plates are mounted on the two sides of the box body of the photovoltaic transformer respectively while radiators are arranged on the other two sides; a fuse is arranged on a dividing box arranged on the left side of the box body; an oil temperature relay, a pressure control relay and a pressure alarm relay are arranged above the fuse; an integrated inverter, an energy-saving transformer, DC, AC control protection units and a comprehensive communication management module are also arranged in the box body; and a low-voltage input sleeve is arranged on the right side of the dividing box while a high-voltage output sleeve is arranged on the other side of the dividing box. The multifunctional integrated photovoltaic box type transformer substation provided by the invention is low in investment cost, short in construction period, simple to install and debug, attractive in appearance, and suitable for large-scale photovoltaic grid-connection systems in complex environments, such as deserts, intertidal zones, high-altitude regions, severe-cold areas and the like.

Description

technical field [0001] The invention relates to a photovoltaic box change, in particular to a multifunctional integrated photovoltaic box change. Background technique [0002] Traditional on-site inverter booster equipment has high investment costs, relatively large infrastructure construction workload, long construction period, on-site installation and construction are difficult, and after completion, more complicated installation and commissioning are required, and the volume It is bulky and has high requirements for the site environment.
