Problems solved by technology

[0003] The causes of electrical fires are generally caused by electrical leakage or high temperature in electrical equipment. Even if the electrical room is located in the coastal area, the air humidity is high, and there is also the possibility of electrical fires. However, the existing electrical cabinets use There are still some deficiencies in the temperature over-standard monitoring and alarm device. The alarm method is relatively simple. Outside of working hours, because the technicians are far away from the power electrical cabinet, the alarm sound on the power electrical cabinet cannot serve as a warning, and it is easy to cause a large accident. Safety accidents cause huge property losses. At the same time, they do not have the function of automatic fire extinguishing, which is easy to further expand the fire and cause incalculable losses. Therefore, at this stage, there is an urgent need for an electric power cabinet with an alarm function for excessive temperature to solve the above problems.

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...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of electrical fire prevention, and in particular relates to a timely use method for an electric power cabinet with an alarm function for exceeding the temperature. Background technique [0002] The power electrical cabinet is a cabinet processed from steel to protect the normal operation of components. The materials for making electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Compared with hot-rolled steel sheets, cold-rolled steel sheets are softer and more suitable for the production of electrical cabinets. Power electrical cabinets are widely used mainly in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry and so on. [0003] The causes of electrical fires are generally caused by electrical leakage or high temperature in e...
