The basic principle of an electrical fire monitoring system is that when the parameters such as current and temperature in electrical equipment are abnormal or abrupt, the terminal probes (such as residual current transformers, temperature sensors, etc.) use the electromagnetic field induction principle and changes in temperature effects to this information. Collect and send it to the monitoring detector. After amplification, A / D conversion, CPU analyzes and judges the amplitude of the change, and compares it with the alarm set value. Once it exceeds the set value, it sends an alarm signal, and at the same time It is also sent to the monitoring equipment, which is further identified and judged by the monitoring equipment. When it is confirmed that a fire may occur, the monitoring host sends out a fire alarm signal, lights up the alarm indicator, sounds an alarm, and displays a fire alarm on the LCD screen. And other information. The staff on duty will quickly go to the accident site for inspection and processing based on the information displayed above, and send the alarm information to the centralized console.

Under normal operation of the system, the unbalanced capacity and electrical location of single-phase loads (such as electrified railways, electric arc furnaces, and electric welding machines) in a three-phase system will cause the three-phase imbalance in the system.
