Problems solved by technology
[0003] For the open-type zero-sequence current transformer, its iron core is a specially customized oval structure. When loading the mold, a plug-in plate will be installed at the cut-off position on the mold to ensure that the cut-off iron core position is reserved, so the iron core and The matching size of the mold is particularly critical. Once the size of the iron core and the mold are not properly matched, the mold will not be able to be installed

The invention discloses a special-shaped iron core inspection tool, an inspection method and a forming method, and belongs to the technical field of zero sequence current transformer inspection, and the special-shaped iron core inspection tool is characterized in that the special-shaped iron core inspection tool at least comprises a measuring body of a rectangular structure; the two ends of the upper edge of the measuring body are respectively provided with first measuring grooves for detecting a first iron core; the distance between the two first measuring grooves is D; the two ends of the lower edge of the measuring body are respectively provided with second measuring grooves for detecting a second iron core; the distance between the two second measuring grooves is L; and the center of the measuring body is provided with a T-shaped through hole. By adopting the technical scheme, the size of the elliptical iron core can be detected, and the size matching relation between the iron core and the mold is ensured.
Description
technical field [0001] The invention belongs to the technical field of inspection of zero-sequence current transformers, and in particular relates to an inspection tool, an inspection method and a forming method for a special-shaped iron core. Background technique [0002] As we all know, open-type zero-sequence current transformer products are divided into two types: integral type and combined type. The transformer is made of engineering plastic shell, and the resin is poured into a fully sealed. Beautiful appearance, convenient installation, saving installation space, many specifications and varieties, applicable to various protection devices and various operation modes of power systems (neutral point grounding, neutral point ungrounding, large resistance grounding, small resistance grounding and arc suppression The need for coil grounding. [0003] For the open-type zero-sequence current transformer, its iron core is a specially customized elliptical structure. When the...
