Research on EMI Noise Suppression Method based on Electromagnetic Shielding of Cabinet
This paper mainly analyzes the influence of cabinet characteristics on the shielding effectiveness of the transmission control cabinet. Through the CST electro-magnetic simulation software, the simplified model of the actual transmission control cabinet is established, and the excitation source is set. The influence of the opening position of the cabinet, the shape of the opening and the design of the shielding layer of the cabinet on the shielding effectiveness of the transmission control cabinet are studied, thereby improving the electromagnetic characteristics of the cabinet
