The invention discloses a rainproof and dehumidification method and system for an outdoor high-voltage control cubicle. The rainproof and dehumidification method for the outdoor high-voltage control cubicle comprises the following steps: acquiring air humidity and temperature at a ventilation opening of the control cubicle and in the control cubicle; if the internal temperature T1 of the control cubicle is larger than or equal to 35 DEG C, when the humidity RH2 at the ventilation opening is larger than 1.5 times of the internal humidity RH1 of the control cubicle, an exhaust fan is turned on, and the ventilation mode at the ventilation opening is V1; when the humidity RH2 at the ventilation opening is smaller than the internal humidity RH1 of the control cubicle, an exhaust fan is turned on, and the ventilation mode at the ventilation opening is made to be V2; if the internal temperature of the control cubicle is T1lt; when the humidity RH2 at the ventilation opening is larger than the humidity RH1 in the con
