The invention discloses a power electrical cabinet with a temperature standard-exceeding alarm function and a using method thereof. The power electrical cabinet belongs to the technical field of electrical
fire prevention and comprises a power electrical cabinet body and an
intelligent control system arranged on one side of the power electrical cabinet body, a
thermocouple sensor is arranged on the inner side wall of the power electrical cabinet body, and a
carbon dioxide fire extinguisher is arranged at the bottom of the inner side wall of the power electrical cabinet body. In the present invention, a
thermocouple sensor, a
microcontroller, a fire extinguishing drive circuit, an electromagnetic control valve, a
carbon dioxide fire extinguisher, an electric push rod, a voice drive circuit,a voice player, an SIM card circuit, a monitoring
alarm device and an intelligent terminal are matched with one another; the
carbon dioxide fire extinguisher is used for extinguishing fire, automaticand timely fire extinguishing in the
electric power electrical cabinet body is achieved, the fireproof performance is good, huge losses caused by
fire disasters are reduced, multiple alarm protectionis achieved, and more losses caused by
chain reaction due to the fact that the temperature in the
electric power electrical cabinet body is too high are further reduced.
