The invention provides a power distribution cabinet with electric leakage reminding. The power distribution cabinet comprises an accommodation cavity surrounded by the outer wall of the cabinet body and the inner wall of the cabinet body. A cabinet body cover is arranged on the outer wall of the cabinet body and the inner wall of the cabinet body. An electric leakage protection cavity is arranged between the outer wall of the cabinet body and the inner wall of the cabinet body. An electric leakage sensor is arranged in the electric leakage protection cavity. A CPU processing module, a temperature sensor, a humidity sensor and a wireless transmission module are arranged in the accommodation cavity. The electric leakage sensor, the temperature sensor and the humidity sensor are in output connection with the CPU processing module. The communication interface of the CPU processing module is connected with the wireless transmission module. The power distribution cabinet has the advantages that the power distribution cabinet can monitor the electric leakage information of the power distribution cabinet, can promptly remind a user, can monitor temperature and humidity information in the power distribution cabinet in real time, and has an electric leakage protection function.
