Nowadays, electrical products are ubiquitous and difficult to leave in people's daily lives and work. Lighting systems, security systems, household appliances, and so on all rely on electricity, and all of these rely on electricity safety. The widespread use of electricity has increased the likelihood of causing electrical accidents. Electrical fires have become the number one killer of various types of fire accidents. Can't we still be awakened by the horrifying tragedies that keep us in awe? And how to effectively prevent and control it is a serious issue before us.

Since humans entered the electrical age, in order to meet the needs of electrical safety, devices such as pull switches, fuses, leakage switches, circuit breakers, and air switches have been invented and manufactured. As is well known, end users mainly use air switches and leakage protection switches for electricity. These two types of electrical protectors are single switches and have a large number. Often, a fault can only be found by inspecting all distribution boxes. However, due to the suddenness of power faults, real-time processing is difficult, so electricians need to constantly inspect and repair them, resulting in high maintenance and management costs.

The fires and widespread power outages caused by leakage and short circuits have caused serious losses to the lives and property of users, and have also caused great trouble to electricity management. Therefore, the various traditional switches currently used cannot effectively prevent the occurrence of electrical fires. The hidden danger of electrical fires is like the presence of trichlorocyanine in milk, which needs to be detected and eliminated instead of being covered up. The danger will always erupt one day.

Faced with the issue of safe electricity use in the new situation, world electrical authorities have proposed the electrical safety protection concept of "prevention first, comprehensive protection", which changes from passive to active. Japan has been enforcing electrical fire monitoring and safety technology since the late 1980s. As a result, the proportion of electrical fires in total fires in Japan has broken through from 30% to 2%.

Faced with the increasingly severe situation of electrical fires, Siemens electrical fire monitoring system was born with the advanced concept of "prevention is better than disaster relief". The Siemens electrical fire monitoring system can accurately and 24/7 monitor changes in leakage, current, temperature, and other factors in the circuit. When there is an abnormality in the circuit, an alarm signal can be quickly sent out and the fault point can be accurately reported, and electrical professionals can be notified to promptly investigate the hidden dangers of electrical fires. The circuit should not operate with faults or abnormalities, and the invisible and intangible electricity consumption situation can be turned into visible digital monitoring, thus eliminating electrical fires in their early stages and providing a comprehensive solution for effectively preventing electrical fires.

The Siemens electrical fire monitoring system is a means of fire prevention, characterized by leakage monitoring being an early warning system. Unlike the "automatic fire alarm system" that acts after a fire occurs to reduce losses, the Siemens electrical fire monitoring system is designed to avoid losses.

With the rapid development of China's economic construction, electricity consumption in production and daily life has increased significantly. Moreover, modern buildings come in various shapes and shapes, and indoor and outdoor decoration and electrical wiring are more complex. Therefore, electrical fires have also increased dramatically, causing huge losses to the national economy and people's lives and property. According to statistics, 80% of fires in China are caused by building fires, and electrical fires are the primary factor causing building fires. Most electrical fires are caused by short circuits, leakage currents, circuit breakers, or overloaded lines, especially those caused by damp environments, insulation damage, and residual currents generated by increased capacitance of lines to ground. In order to effectively prevent electrical or circuit fires, Siemens electrical fire monitoring systems have emerged.

The detection objects for general electrical fires include residual current and temperature rise, corresponding to residual current type electrical fire monitoring detectors and temperature measurement type electrical fire monitoring detectors:

1. The residual current Siemens electrical fire monitoring system can continuously monitor the changes in residual current of the circuit in real-time for a long time, and grasp the trend of changes in insulation performance of electrical circuits or equipment at any time;

2. The temperature measuring detector detects the change in its resistance value to achieve temperature measurement, and when it reaches the alarm set value, it will sound an alarm, achieving prevention and preventive measures.

Therefore, the Siemens electrical fire monitoring system is designed to prevent and eliminate electrical fires in the power system before a fire occurs, avoiding losses caused by electrical fires
