Curing production process of ultracrystalline iron core for current transformer

Abstract

The invention discloses a curing production process of an ultracrystalline iron core for a current transformer, and relates to the technical field of curing production of the ultracrystalline iron core for the current transformer. The curing production process of the ultracrystalline iron core for the current transformer comprises the following steps of S1, mixing and configuring; S2, processing the ultracrystalline iron core; S3, drying, curing and forming; and S4, carrying out secondary curing. According to the curing production process of the ultracrystalline iron core for the current transformer, a production process is cured, epoxy resin pouring sealant is used as a raw material, the epoxy resin pouring sealant is uniformly stirred after being mixed in proportion, a mixed glue solution is obtained, the ultracrystalline iron core subjected to heat treatment and paint dipping is brushed, the iron core is placed in a constant-temperature drying box to be heated for curing and shaping, and a silicone grease transparent curing agent is used for secondary curing so that the hardness of the iron core is obviously improved, a performance change of a mutual inductor after pouring is reduced, the installation of a protection box is replaced, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of solidification production of ultramicrocrystalline iron cores for current transformers, in particular to a solidification production process for ultramicrocrystalline iron cores for current transformers. Background technique [0002] The principle of current transformer is based on the principle of electromagnetic induction. A current transformer consists of a closed core and windings. Its primary side winding has few turns, and it is connected in series with the current line that needs to be measured, so it often has all the current of the line flowing, and the secondary side winding has more turns, and is connected in series in the measuring instrument and protection circuit. When the current transformer is working, its secondary side circuit is always closed, so the impedance of the series coil of the measuring instrument and the protection circuit is very small, and the working state of the current t...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a solidification production process of an ultramicrocrystalline iron core for a current transformer, which solves the problem that the hardness of the iron core is relatively weak and the performance of the transformer after pouring is poor. More changes, increase the consumption of raw materials, thus increasing the production cost
