Embodiment Construction
[0020] The embodiments described in the present invention are illustrative, rather than limiting, so the present invention is not limited to the embodiments described in the specific implementation, any other implementation obtained by those skilled in the art according to the technical solution of the present invention way, also belong to the protection scope of the present invention.
[0021] The current common transformer low-voltage side line structure is as follows: figure 1 As shown, the low-voltage side has two branches, branch A and branch B. When a fault occurs at any point K1 to K5 in the figure, the existing protection scheme will cut off branch A and branch B in turn, and cannot intelligently judge the fault. point.
[0022] The invention provides a method for selectively removing the fault point in the double-branch line on the low-voltage side of the transformer. The main steps are: when a ground fault occurs, first measure the ground transformer Z N The zero-s...
