A hollow high-voltage wire hot fluid ice melting system comprises a high-voltage wire body. The high-voltage wire body is provided with a hollow cavity allowing hot fluid to pass through, and the axial direction of the hollow cavity and the axial direction of the high-voltage body coincide. The hot fluid is heated gas, and alternating current flows through the high-voltage wire body. Under the effect of a skin effect, current at the center of a high-voltage wire is weak, and the electric conduction signification is slight. The high-voltage body is set to be hollow, so that the hot fluid conveniently flows into the hollow high-voltage wire body to smelt accumulated ice on the high-voltage wire.
