Current transformer is an electrical device used to measure current, widely used in power systems, industrial control, and electronic equipment. Its main function is to convert high current into low current for measurement and monitoring. The production process of current transformers is a complex process that requires multiple steps to complete. Below, we will detail the common production processes of current transformers.

First, the production process of current transformers usually starts with the preparation of raw materials. The main materials required for producing current transformers include iron cores, winding wires, insulation materials, etc. The iron core is the core component of the current transformer, usually made of silicon steel or iron oxide materials. The winding wire is used to wind around the iron core, usually made of copper wire or aluminum wire. The insulation material is used to wrap the winding wire to prevent short circuits between the winding wires.

Next is the processing of the iron core. The iron core is the core component of the current transformer, and its shape and size have a significant impact on the performance of the current transformer. The iron core usually needs to undergo processes such as cutting, stamping, grinding, etc., to ensure its dimensional accuracy and surface smoothness. During the processing, the iron core also needs to undergo magnetization treatment to improve its magnetic permeability and magnetic saturation.

Then comes the winding of the wire. The wire winding is another important component of the current transformer, and the quality of the winding directly affects the measurement accuracy and stability of the current transformer. The wire winding usually needs to be done by an automatic winding machine to ensure the density and uniformity of the winding. During the winding process, the wire also needs to undergo stretching and heat treatment to improve its conductivity and heat resistance.

Next is the wrapping of the insulation material. The insulation material is used to wrap the winding wire to prevent short circuits and insulation breakdown between the winding wires. Insulation materials are usually made of materials such as polyester film, polyvinyl chloride, etc., and their thickness and quality have a significant impact on the insulation performance of the current transformer. During the wrapping process, the insulation material needs to undergo processes such as cutting and winding to ensure its tight integration with the winding wire.

Finally, the assembly and testing of the current transformer. During the assembly process, the iron core, winding wire, and insulation material need to be assembled according to design requirements, followed by processes such as welding and fixing. During the testing process, the current transformer needs to undergo electrical performance testing, insulation performance testing, etc., to ensure that it meets design requirements and standards.

In summary, the production process of current transformers is a complex process that requires multiple steps to complete. Only by strictly controlling the quality at each step can high-performance and accurate current transformer products be produced. We hope that through this article, readers have gained a deeper understanding of the production process of current transformers.
