Embodiment 1
[0025] like Figure 1-4 Among them, an electric power cabinet with a temperature exceeding standard alarm function, comprising a power electric cabinet body 1 and an intelligent control system 20 arranged on one side of the power electric cabinet body 1, the inner side wall of the power electric cabinet body 1 is set There is a thermocouple sensor 2, and a carbon dioxide fire extinguisher 3 is provided at the bottom of the inner wall of the power electrical cabinet body 1, and the side of the carbon dioxide fire extinguisher 3 is fixedly connected with a lifting seat 4, and the lifting seat 4 is slidably connected to the power electrical cabinet cabinet In the sliding groove 5 provided on the inner side wall of the body 1, the inner end surface of the sliding groove 5 is fixedly connected with the surface of the lifting seat 4 through the electric push rod 6;
[0026] Described intelligent control system 20 comprises microprocessor 10, and the input end of described microproce...
Embodiment 2
[0035] like Figure 1-4 Among them, the working principle of the present invention is: when in use, a plurality of thermocouple sensors 2 can monitor the temperature of different levels inside the electric cabinet body 1 in real time, and respectively form analog signals of relevant information, and then simulated by multiple channels The switch 8 completes the signal switching function in the signal chain respectively, and the data acquisition card 9 automatically collects each digital signal and sends it to the microprocessor 10 for analysis, processing and judgment, and the microprocessor 10 can calculate several The average temperature of the thermocouple sensor 2 is then sent to the memory 18 for storage. When the average temperature exceeds the set temperature, on the one hand, the microprocessor 10 will first control the electric pusher through the fire extinguishing drive circuit 19. The rod 6 stretches in the sliding groove 5, so that the carbon dioxide fire extinguis...
Embodiment 3
[0040] like Figure 1-4 Among them, the usage method of the present invention is:
[0041] 1) Through multiple thermocouple sensors 2, the temperature at different levels inside the power cabinet 1 can be monitored in real time, and analog signals of relevant information can be formed respectively;
[0042] 2) The analog signal is respectively completed by the multi-channel analog switch 8 to perform the signal switching function in the signal chain, and the data acquisition card 9 automatically collects each digital signal and sends it to the microprocessor 10 for analysis, processing and judgment;
[0043] 3) Then the microprocessor 10 calculates the average temperature of several thermocouple sensors 2, and then sends this average value to the memory 18 for storage;
[0044] 4) When the average temperature exceeds the set temperature, the microprocessor 10 will first control the electric push rod 6 to stretch in the sliding groove 5 through the fire extinguishing drive cir...
