Title:
INVERTER, PHOTOVOLTAIC POWER GENERATION SYSTEM AND DEHUMIDIFICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/056900
Kind Code:
A1
Abstract:
An inverter (200), a photovoltaic power generation system, and a dehumidification method. The inverter (200) comprises: an air-permeable valve (20) and an airflow transmission device (30); the air-permeable valve (20) is mounted on the surface of a cabinet cavity (10) of the inverter (200); a controller (40) and the airflow transmission device (30) are located in the cabinet cavity (10); an air-permeable membrane (21) is provided on the air-permeable valve (20); and when at least one of the following preset conditions is satisfied, the airflow transmission device (30) blows air in the cabinet cavity (10) to the air-permeable membrane (21), so that the air in the cabinet cavity (10) overflows out of the cabinet cavity (10) through the air-permeable membrane (21), wherein the at least one preset condition comprises at least one or more of: the operation of the inverter (200), the humidity in the cabinet cavity (10) being greater than a preset humidity, and the temperature in the cabinet cavity (10) being greater than a preset temperature. The airflow transmission device (30) is provided in the cabinet cavity (10) of the inverter (200), and high-humidity air in the cabinet cavity (10) is blown to the air-permeable membrane (21) of the air-permeable valve (20), so that the high-humidity air in the cabinet cavity (10) overflows out of the cabinet cavity (10) through the air-permeable membrane (21), so as to force air in the cabinet cavity (10) to be discharged, reduce humidity in the cabinet cavity (10), and protect electrical components in the inverter (200).
