Zusammenfassung:	The utility model discloses a rainproof frequency converter. The rainproof frequency converter comprises a casing, wherein the lower portion of the casing is provided with an air inlet, the upper portion of the casing is provided with an air outlet, the air outlet is provided with an axial-flow fan, the rainproof frequency converter further comprises an air guide pipe arranged at the lower portion of the air inlet, and the air guide pipe is internally provided with a moisture separator. According to the rainproof frequency converter, the moisture separator is arranged at the lower portion of the air inlet of the frequency converter casing, cooling air entering the frequency converter casing is dried through the moisture separator, so moisture is prevented from damaging components in the frequency converter, the fault rate of the frequency converter can be reduced, and service life of the frequency converter is prolonged.
