Current transformer

The embodiment of the invention discloses a current transformer and relates to the technical field of electronic equipment. The current transformer comprises a current transformer body, a current transformer base and a current transformer socket. The current transformer body comprises a magnetic ring, a primary winding, a secondary winding, a shunt connected onto a circuit to be detected in series and a secondary wiring terminal. By means of the structural design, the influence of the internal structure and external environment factors on the current transformer in the prior art is reduced, accuracy errors of the current transformer, brought by the controllable factors, are decreased, the accuracy of the current transformer is improved, and the accuracy of a measurement result is improved.
