Connecting plate structure penetrating through zero sequence current transformer

The utility model relates to the technical field of low-voltage electric appliances, in particular to a connecting plate structure penetrating through a zero-sequence current transformer, which comprises an A-pole connecting plate, a B-pole connecting plate, a C-pole connecting plate and an N-pole connecting piece, the A-pole connecting plate comprises a front left bending plate and a rear left bending plate, the B-pole connecting plate is of an arch structure, and the C-pole connecting plate is of an arch structure. And the C-pole connecting plate comprises a front right bent plate and a rear right bent plate. The A-pole connecting plate and the C-pole connecting plate are both of a two-in-one splicing and connecting structure, the problem that the connecting plates cannot penetrate through a center hole of the zero-sequence current transformer after being integrally formed is solved, the A-pole connecting plate and the C-pole connecting plate are provided with interphase insulating partition plates at the p
