背景技术 Background technique
对于大型光伏并网发电系统，为了较少电池组件与逆变器之间连接线，以及日后维护方便，通常情况下，需要在电池组件与逆变器之间增加光伏阵列汇流箱以把多路的阵列输入汇成一路输出，方便逆变器接线。目前常见的光伏阵列汇流箱一般较为简单，仅仅是将输入的多路阵列汇成一路输出，通常没有接入熔丝或仅仅在一路阵列输入的正极或负极接入熔丝，无法防止此阵列另一未接入熔丝的负极或正极发生断路，从而损坏整个系统，降低了系统的可靠性。For large-scale photovoltaic grid-connected power generation systems, in order to reduce the number of connecting lines between battery components and inverters and facilitate maintenance in the future, it is usually necessary to add a photovoltaic array combiner box between battery components and inverters to connect multiple The input of the array is combined into one output, which is convenient for inverter wiring. At present, the common photovoltaic array combiner box is generally relatively simple. It only combines multiple input arrays into one output. Usually, there is no fuse or only the positive or negative input of one array is connected to the fuse, which cannot prevent the array from being connected to another A negative or positive electrode that is not connected to the fuse is disconnected, which damages the entire system and reduces the reliability of the system.
