Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of silicon steel core, and more specifically, particularly relates to a silicon steel core with good insulation and protection performance. Background Art
[0002] Silicon steel core is a special material, usually used to manufacture power equipment such as transformers and motors. It is composed of silicon steel sheets, which have the characteristics of low magnetic permeability and high resistivity, which can reduce the eddy current loss of the iron core and the Joule heat loss of the copper wire, thereby improving the efficiency of the equipment. The main function of silicon steel core is to act as a magnetic circuit conductor in power equipment to transmit and convert electrical energy. Through the reasonable design and use of silicon steel core, the performance of the equipment can be improved and energy consumption can be reduced.
[0003] Based on the above, the inventors have found the following problems: most of the current silicon steel cores are composed of multiple silicon steel sheets. During the assembly process, dust may remain between the silicon steel sheets, and the presence of dust may affect the insulation protection of the core.
[0004] Therefore, in view of this, research and improvement are conducted on the existing structure and defects to provide a silicon steel core with good insulation protection, in order to achieve a purpose with greater practical value. Utility Model Content
[0005] In order to solve the above technical problems, the utility model provides a silicon steel core with good insulation protection, so as to solve the problem that the insulation protection of the existing silicon steel core may be affected by dust during assembly.
[0006] The purpose and effect of the utility model of a silicon steel core with good insulation protection are achieved by the following specific technical means:
[0007] A silicon steel core with good insulation protection comprises a silicon steel sheet body, the surface of the silicon steel sheet body is coated with insulating paint, a protective film is adhered to the surface of the insulating paint, a tear strip is installed on the surface of the protective film, and an insulating layer is installed inside the silicon steel sheet body.
[0008] Furthermore, the size of the protective film matches the main body of the silicon steel sheet.
[0009] Furthermore, a circular hole is provided on the surface of the silicon steel sheet body, and a limiting groove is provided on the surface of the circular hole.
[0010] Furthermore, the insulating paint is made of phenolic resin.
[0011] Furthermore, the material of the insulating layer is epoxy glass fiber.
[0012] Furthermore, a plurality of winding pins are installed on the surface of the silicon steel sheet body.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] The utility model uses the protective film and the tear strip in combination. When the silicon steel core needs to be assembled, it is only necessary to tear off the tear strip, which will drive the protective film to be torn off, and then the silicon steel sheets can be assembled. Through the above design, dust on the silicon steel sheets during the assembly process can be effectively reduced, thereby improving the insulation protection.
[0015] The use of insulating varnish can effectively isolate the magnetic flux between silicon steel sheets, prevent oxidation and corrosion, and increase the life of the equipment. At the same time, phenolic resin also has high heat resistance and can withstand working environments at higher temperatures, ensuring the stability and insulation performance of the insulating varnish under high temperature conditions.
[0016] The use of the insulating layer can effectively improve the insulation strength and mechanical strength between silicon steel sheets. At the same time, the epoxy glass fiber also has good chemical corrosion resistance and can resist the erosion of a variety of chemical substances, keeping its insulation performance unaffected.
