Problems solved by technology

In the process of switching between solar energy and mains power, the mechanical switch is operated manually to switch, and it is often manually switched when the battery is dead or the power is insufficient and the power is cut off, and the phenomenon of flashing lights (that is, short-term power failure) often occurs , it is difficult to ensure the normal work, and the operation is troublesome, which affects the service life of the pump unit
And it cannot realize the self-adaptive compensation function of solar energy priority and utility power backup
In addition, most of the existing control devices operate for a long time in a high-humidity environment, which is prone to corrosion, poor working stability and short service life

Abstract

The invention discloses a control device for realizing photovoltaic and alternating current parallelized self-adaptive compensation. The control device comprises a touch display screen, a seal gasket, a self-adaptive compensation PCB (printed circuit board) control panel, an insulation shell and a rear cover. The control device is ingenious and reasonable in structural design, an effective seal structure is formed on a contact surface of the insulation shell and the touch display screen through the seal gasket to obtain excellent waterproof and dustproof effects, and accordingly the control device has a function of corrosion resistance in long-time operation in a high-humidity environment, and environment adaptability and stability in use are greatly improved while service life is prolonged greatly. When quantity of solar electricity stored in an electricity storage module is consumed to a preset value, the mains supply is converted into direct-current through the self-adaptive compensation PCB control panel to realize automatic seamless cut-in, and switching after sudden power failure caused by electricity shortage is avoided. By adoption of a solar power generation module for charging the electricity storage module, seamless connection between solar energy and the mains supply is realized while photovoltaic and alternating current parallelized self-adaptive compensation is realized, and solar utilization efficiency is improved effectively.

Description

technical field [0001] The invention relates to the technical field of photovoltaic irrigation stations, in particular to a control device applied to photovoltaic irrigation stations to realize light-crossing parallel self-adaptive compensation. Background technique [0002] Photovoltaic irrigation station, also known as solar irrigation station, as an important agricultural infrastructure, provides water for agricultural production and life. The solar lifting irrigation station is mainly composed of a solar power generation system and a lifting irrigation system. The solar power generation system includes solar panels, photovoltaic controllers and photovoltaic inverters; the lifting irrigation system mainly includes water pump units, pipelines, control rooms and storage tanks. Among them, the water pump unit mainly includes submersible pumps and motors. The solar panel converts the collected sunlight into direct current, inputs it into the photovoltaic controller, and the...
