Embodiment example 1
[0019] The invention provides a technical solution: a solidification production process of an ultramicrocrystalline iron core for a current transformer, comprising the following steps:
[0020] S1. Mixing configuration: use epoxy resin potting glue as raw material, mix according to the ratio of 2:1 and stir evenly to obtain mixed glue A;
[0021] S2. Ultramicrocrystalline iron core treatment: the ultramicrocrystalline iron core is heat treated sequentially and dipped in paint;
[0022] S3. Drying and curing molding: apply the mixed glue A in step S1 and mixing to the surface of the ultramicrocrystalline iron core in step S2, the ultramicrocrystalline iron core treatment, and place the coated ultramicrocrystalline iron core on Heating in a constant temperature drying oven for curing and setting;
[0023] S4. Secondary curing: During step S3, drying and curing, after curing and shaping, the ultramicrocrystalline iron core is secondarily cured with a silicone grease transparent ...
