The invention relates to the technical field of electric leakage protection devices, and discloses a distributed photovoltaic power station electric leakage protection device, which comprises a main body, a tightening assembly and a fixing assembly, the inner wall of the main body is movably connected with a movable brake, the inner wall of the top of the main body is fixedly provided with a limiting pipe, and the inner wall of the limiting pipe is movably connected with an electric wire. Through cooperative use of all structures in the tightening assembly, the fixing assembly and the clamping assembly, when a wire extends into the main body through the limiting pipe and is connected with the main body, the outer wall of the wire can be firmly fixed, and the situation that a traditional electric leakage protection device is fixed through a bolt when being connected with the wire is avoided; and besides structural cooperation of all the assemblies, an annular sealing rubber mat is further arranged on the inner
