Abstract：Now the main components of electrical equipment installed in the electrical control cabinet are electronic components and chips. These components are very sensitive to electromagnetic interference. While the electromagnetic interference in the substation is very strong, it has a great influence on the operation of electrical devices. Therefore, it is necessary to design an electrical control cabinet with electromagnetic interference shielding function to meet the safe and stable operation of electrical equipment. Based on the analysis of the electromagnetic interference source in the substation, this paper designs an electrical control cabinet with electromagnetic shielding function from the aspects of cabinet material selection, cabinet door design, sealing design and grounding design. This design can effectively reduce the influence of electromagnetic interference on the electrical equipment in the cabinet and ensure the safe and stable operation of the equipment.
