摘要
针对光伏组件用光伏接线盒在大型光伏电站现场使用过程中出现的失效现象进行分析研究。通过对光伏接线盒的外观检测、电流-电压(I-V)特性分析以及进一步的解剖测试分析,在二极管解剖出的芯片表面保护环位置发现多处烧熔点,确定是雷击造成的二极管击穿导致接线盒失效。
The failure phenomenon of the junction box used for photovoltaic modules in a large-scale photovoltaic power station was investigated.This investigation involved the visual inspection of the junction box,analysis of its voltage-current(I-V)characteristics,and further dissection testing and analysis.Ultimately,the burn marks were discovered on the protection ring position of the diode’s surface after dissection.The failure of the junction box was attributed to diode breakdown induced by lightnin strike.
