The solar anti-interference and anti-reflux unidirectional shielding system is applicable to solar cell power transmission and distribution systems, electric energy of solar cell packs can be collected and rectified through the header cabinet, and external signal interference can be effectively avoided by the aid of the shield connected into the system, so that interference resistance of the system is improved, and reverse current can be shielded.

Description

Technical field: [0001] The invention relates to the technical field of photovoltaic systems, in particular to a solar energy anti-interference and anti-backflow one-way shielding system. Background technique: [0002] Solar cells are the product of human development and utilization of new energy. Solar cells can collect and convert solar energy into electrical energy for human use. In the prior art, after solar cells or solar cell groups are connected to the transmission and distribution circuit system, conduction reverse currents often occur due to lightning series attacks, incorrect construction methods, wrong positive and negative polarities, or changes in the circuit environment , resulting in power loss and damage to electrical components. Moreover, the electric energy collection and transmission and distribution circuits of traditional solar cells are easily interfered by other signals, and the anti-interference ability of the circuit system is poor, and it is relati...
