HIGH-CURRENT SYNTHESIS CIRCUIT OF ELECTRONIC CURRENT TRANSFORMER

摘要

A high-current synthesis circuit of an electronic current transformer. The high-current synthesis circuit comprises two rectangular frames that are symmetrically connected through a lead copper bar (3). Ten turns of conductor copper bars are arranged in a framework of each rectangular frame. The lead copper bar (3) comprises four copper bar taps (4), and each rectangular frame is provided with two copper bar taps (4). Any copper bar tap of one rectangular frame and any copper bar tap of the other rectangular frame serve as the output ends of an alternating-current circuit unit, and the other two copper bar taps serve as the output ends of a direct-current circuit unit. An 8-shaped wrapping structure is adopted, multiple turns of primary wires are equally distributed on the circumference of a winding, a magnetic field generated by the wires is even in subsection on the whole, and twenty-thousand-ampere primary high-current can be output.
