Problems solved by technology

[0004] Traditional photovoltaic substations generally adopt the scheme of "inverter room + photovoltaic box change", that is, the inverter room and photovoltaic box change room are independent structures, and are connected by wires in the middle. There are many materials, and the installation site also needs a certain amount of debugging time

Abstract

Disclosed is a photovoltaic pre-assembled transformer substation apparatus. The photovoltaic pre-assembled transformer substation apparatus comprises an inverter mounting region, a transformer mounting region and a high-voltage switch cabinet which are packaged together through a shell; inverters are mounted in the inverter mounting region, and a communication cabinet and a transformer are mountedin the transformer mounting region; a thermal insulation layer is arranged between the inverter mounting region and the transformer mounting region, and between the transformer mounting region and the high-voltage switch cabinet separately; the inverters, the transformer and the high-voltage switch cabinet are connected through a primary wire; a ventilating port is formed in the shell; a controlsystem and an alarm are arranged in the shell; the control system comprises a temperature control system, a humidity control system, a video monitoring system and a smoke monitoring system; and the control system transmits all kinds of collected data to a main control room through the communication cabinet. By virtue of the photovoltaic pre-assembled transformer substation apparatus, the inverters, the transformer and the high-voltage switch cabinet are integrated effectively, so that space dimension is reduced and the mounting mode is simplified.

Description

technical field [0001] The invention relates to photovoltaic power station equipment, in particular to a photovoltaic preinstalled substation device. Background technique [0002] Abundant solar radiant energy is an important energy source. Solar radiant energy has the advantages of inexhaustible, inexhaustible, pollution-free, cheap, and can be freely utilized by human beings. The photovoltaic power station refers to a photovoltaic power generation system that uses solar energy and uses special materials such as crystalline silicon panels, inverters and other electronic components to connect to the grid and transmit power to the grid. [0003] Photovoltaic substation belongs to the power transmission link of photovoltaic power station and is a complete set of power distribution equipment. [0004] Traditional photovoltaic substations generally adopt the scheme of "inverter room + photovoltaic box change", that is, the inverter room and photovoltaic box change room are inde...
