Abstract
The invention relates to the field of transformers, and discloses a zero sequence current transformer prepared by a pressure gelatin technology. The zero sequence current transformer comprises a zero sequence current transformer part, wherein the zero sequence current transformer part comprises a housing; a ring iron core wound with a coil is arranged in the housing; the ring iron core is formed by magnetically connecting two semi-ring iron cores; the two semi-ring iron cores are a first semi-ring iron core and a second semi-ring iron core; the first semi-ring iron core is located above the second semi-ring iron core, and wound with the coil; the housing is formed by detachably connecting an upper housing and a lower housing; the upper housing and the lower housing are prepared by pressure gelatin technologies; the first semi-ring iron core is embedded into the upper housing; and the second semi-ring iron core is embedded into the lower housing. The zero sequence current transformer can be mounted under advanced cable laying or electrification conditions; and power construction and maintenance renovation projects are greatly facilitated.
Description
