Dustproof photovoltaic energy storage inverter adapted to humid environment

Abstract

The invention discloses a dustproof photovoltaic energy storage inverter suitable for a humid environment, and the inverter comprises a mounting plate, a cabinet body, a floating mechanism, and a damp-proof and dustproof mechanism. The moisture-proof and dust-proof mechanism comprises a support, a PLC, a transmission gear, a transmission rod, a heater, a driving gear, a motor, a sealing disc, a driven gear, an air hole, a fan, a through opening, a fluted disc, a temperature sensor, a humidity sensor, a mounting frame and a housing, the mounting frame is fixedly mounted at the top end of the cabinet body, and the fan is fixedly mounted on the mounting frame. A support is fixedly installed at the position, corresponding to the fan, of the top end in the cabinet body. The beneficial effects are that automatic heat dissipation and dehumidification can be realized through the moisture-proof and dust-proof mechanism, a dust-proof function is realized, the service life of the equipment is further prolonged, the cabinet body can be driven to rise through the floating mechanism when water drainage is unsmooth and the water level rises, rainwater is prevented from entering the equipment, and the protection capability of the inverter is further improved.

Description

technical field [0001] The invention relates to the technical field of inverters, in particular to a dust-proof photovoltaic energy storage inverter adapted to a humid environment. Background technique [0002] Photovoltaic inverters can convert the variable DC voltage generated by photovoltaic solar panels into inverters of mains frequency alternating current, which can be fed back to commercial power transmission systems or used for off-grid power grids. The photovoltaic inverter is one of the important system balances in the photovoltaic array system. It can be used with general AC power supply equipment. Due to the needs of use, the photovoltaic energy storage inverter often needs to be installed outdoors. [0003] Existing photovoltaic energy storage inverters have a simple structure, and most of them only rely on external casings or boxes to protect the inverters. In order to facilitate heat dissipation, most of the casing boxes are provided with ventilation holes, bec...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a dust-proof photovoltaic energy storage inverter suitable for humid environments, which solves the problem that the existing photovoltaic energy storage inverters have a simple structure and mostly only rely on external casings or boxes. The body protects the inverter. In order to facilitate heat dissipation, most of the enclosures are equipped with ventilation holes. Since the ventilation holes are exposed for a long time, dust in the air can easily enter the box and affect the cleaning and heat dissipation of the inverter. As the environment changes, it is very easy to cause the inverter to be damp, causing damage and affecting the service life of the inverter
