Series Power Supply for UAV Inspection in Photovoltaic Power Plants: Efficient Defect Detection via Electroluminescence Technology

The Series power supply supporting UAV inspection is a special supporting equipment for UAV inspection of photovoltaic power plants, also known as Series power supply or UAV string power supply. Its core function is to convert alternating current into direct current and input it into the battery panel, stimulating the electroluminescence effect to achieve the detection of internal defects of photovoltaic panels. For example, problems such as hidden cracks, broken grids, and virtual soldering can be found in this way. The specific working principle is that when a forward bias voltage is applied to the photovoltaic panel, the recombination of minority carriers inside the battery will generate photons. By detecting the luminous intensity and distribution of photons, the defect location of the panel can be accurately positioned.

This type of power supply has multiple specifications to adapt to different scenario requirements. Common compensation voltages include 12V, 96V and other types. It has the function of photovoltaic string reverse connection short - circuit protection, which can effectively prevent the photovoltaic module from breaking down the diode and ensure the safety of equipment and personnel operation. It can simultaneously complete the detection power supply access of 1 to 32 photovoltaic panels (within 1500V) to meet the detection requirements of photovoltaic power plants of different scales. The photovoltaic power - on access ports are rich, including bus boxes, inverters, string ports, component ports and other methods, which are convenient for connecting with various parts of the power plant. It is also equipped with a high - voltage isolation protection device to ensure the safety of operators in high - voltage environments. Its wiring method generally adopts AC220V three - phase three - wire + ground wire to ensure stable power supply.

In terms of product advantages, the Series power supply adopts a program - controlled system customized for the photovoltaic power plant scene, which can improve the safety of on - site manual construction.
