The invention belongs to the technical field of power distribution cabinets, and relates to an intelligent power distribution station house condensation removal device based on a narrowband wireless network. The device comprises a device body, the device body comprises a shell, a display screen is arranged at the top of the front surface of the shell, operation buttons are arranged at the top of the front surface of the shell, a hot air drying assembly is arranged on the front surface of the shell, and a humidity sensor is arranged on the front surface of the shell. The inner cavity of the device body further comprises a main control system, a sensor sensing system, a device communication system, a man-machine interaction system, a power source management system, a device configuration system and a power control system. The structure of the device is reasonable; and due to the fact that the device adopts a heating mode, drainage is not needed, operation of electrical equipment is not affected; since drainage is not needed, electrical short circuit faults cannot be caused; and the RS485 + NB-IOT narrowband Internet of Things is adopted, so that local upper computer connection can be met, wireless communication connection can also be met, the wiring cost is reduced, the electric shock risk is avoided, and the communication rate is high.
