Description

A salt spray resistant photovoltaic grid-connected cabinet

Technical Field

The present invention relates to the technical field of power distribution equipment, and more specifically to a salt spray resistant photovoltaic grid-connected cabinet.

Background Art

With the development of people, the demand for energy is getting higher and higher. With the exploitation of non-renewable energy, non-renewable energy is becoming less and less. People need to avoid using non-renewable energy as much as possible and develop new renewable energy instead. On the road to developing renewable energy, we have gradually made more extensive use of wind energy, hydropower, and solar energy. They are all renewable energy and are beneficial to the generation of natural energy.

Solar energy is a renewable and clean energy. With the promotion and help of the country, solar energy has gradually entered thousands of households, and photovoltaic power stations have also been established one after another. Among them, photovoltaic grid-connected cabinets play an indispensable role in photovoltaic power generation. Photovoltaic power stations are generally built in mountains or coastal areas to receive more heat with maximum capacity and make full use of solar energy for energy generation. However, coastal areas are often accompanied by salt spray, and mountainous areas are often affected by ozone produced by ultraviolet rays. Both of these will corrode the internal lines of the photovoltaic grid-connected cabinets. Over time, the internal lines of the grid-connected cabinets will age and interfere with the grid-connected cabinets from working normally.

Problems caused:

First, traditional photovoltaic grid-connected cabinets are generally protected from corrosion by external coatings, but there are inevitably some gaps in the cabinet structure that allow salt mist to enter, causing corrosion to the internal circuits of the grid-connected cabinet and causing aging of the internal circuits.

Second, traditional photovoltaic grid-connected cabinets generally only have heat dissipation functions and do not have dedicated air inlets. Salt mist can easily enter the cabinet through the gaps when the photovoltaic grid-connected cabinet is dissipating heat.

Third, the ground in coastal areas is relatively humid, and the cabinet body is prone to rust when it contacts the ground, causing damage to the cabinet body.

By turning on the whole power to make the motor rotate, when the air suction motors at the front and rear of the grid-connected cabinet body rotate, the two air suction fan blades are driven to rotate, so that the cabinet performs air suction work. The cold air is filtered through the two filter screens for the first step, and the moisture contained in the air is filtered once. When a lot of moisture is condensed on each filter screen, it drips into the moisture drainage grooves at the front and back, and is discharged through the external mesh cover connected to the bottom of the moisture drainage grooves at the front and back. After the air passes through the two filter screens, it enters the two activated carbon blocks. The two activated carbon blocks further filter and dry the air to ensure that the air entering the machine body is dry. The cold air enters the cabinet to cool down the inside of the cabinet. When the two heat dissipation motors are powered on and run, the two heat dissipation fan blades are rotated. The two heat dissipation fan blades rotate to remove the hot air inside the cabinet. One cold and one hot cool it and its inside, which is beneficial to filter the moisture inside the air during self-inhalation, prevent the cabinet from rusting due to water vapor entering the cabinet during the inhalation process, and protect the safe operation of the internal circuit.
