    I. Current situation of electrical fires
    In recent years, with the continuous increase of electrical load, electrical fire accidents have been increasing day by day, which has brought great harm to the safety of life and property of the country and people. According to the Statistical Yearbook of the Fire Bureau of the Ministry of Public Security, in the investigation of building fire accidents in the past ten years, about 30% originated from fires caused by electrical faults, ranking first. Especially in severe fire accidents, the proportion of electrical fires is as high as 70%. Electrical fires have become the number one killer of various fire accidents! At the same time, due to the increasing power load of industrial and mining enterprises and households, as well as the continuous increase of electrical equipment, the incidence of electrical safety accidents is also rising year by year, resulting in increasingly serious economic losses.

    Causes of electrical fires
    1. Long-term overload and heating of electrical lines cause circuit aging, insulation damage and short circuit, and other abnormalities generate electric sparks, igniting surrounding combustible materials and causing fire; (commonly known as overload, short circuit, leakage, and poor contact)
    2. The awareness of safe power consumption is not strong, due to human factors such as unauthorized changes to electrical circuits and non-compliant use of electrical appliances;
    3. The quality of the selected electrical appliances is poor and the reliability is poor;
    4. In addition to direct lightning, the types of lightning hazards include inductive lightning (including static and electromagnetic induction), lightning strikeback, intrusion of lightning waves, and ball lightning. The common feature of these types of lightning hazards is that they are always accompanied by discharge Mechanical forces, high temperatures and intense sparks. Damage to buildings, damage to power lines or electrical equipment, explosion of oil tanks, and fires in storage yards. The fire caused by a ball mine in Huangdao Oil Depot is a typical example.


    Third, the current electrical fire prevention measures
    At present, electrical equipment operation and management techniques are backward, relying mainly on manual inspections, which have many missed inspections and poor results. For example, the high-voltage switchgear and low-voltage drawers in operation are not allowed to be inspected at all. The floor distribution box cannot be inspected due to a lot of position restrictions. Cable trenches and cable trays are difficult to inspect due to covers and plugs, so they are caused by electrical faults. Electrical fires, electrical explosions, sudden power outages and other electrical accidents still occur from time to time.
    At present, there are not many technical measures for electrical fire prevention. Although leakage protectors are generally installed in buildings, the main focus is to protect the personal electric shock, which has little effect on the prevention of electrical fires. Although a small number of new buildings are equipped with electrical fire monitoring systems, there are still many shortcomings: they only focus on condition monitoring and alarm protection, and severely lack intelligent analysis functions such as fault diagnosis, fault analysis, and trend prediction; they only focus on power distribution. Point-type detection of line leakage and temperature, lack of distributed line detection of cable temperature; only focus on condition monitoring of low-voltage equipment, lack of condition monitoring of high-voltage equipment; only focus on civil buildings, seriously ignore industrial electrical fire prevention, etc. Wait.
    At the same time, the competent government department (such as fire protection) lacks effective supervision means and cannot grasp the electrical safety situation of the units in its jurisdiction. The daily work mainly uses post-accident compensation or surprise inspections, which cannot fundamentally change the passive working situation.
    With the development and application of Internet of Things, cloud computing and big data technologies. At present, the technical means for monitoring the failure of electrical equipment and achieving the safe and controllable operation of electrical systems are in place. The severe electrical fire situation has attracted great attention from the country. The state has formulated and issued relevant notification documents, requiring local governments to vigorously strengthen the management of electrical fires. Strength.
    A. In December 2016, the State Fire Protection Administration clearly stated in the "2017 Work Focus" that "improve the level of fire physical defense technology. Guidance municipalities, provincial capitals, planned cities and cities with conditions to speed up the scientific research results of electrical fire monitoring systems. Promotion and application ";
    B. On May 3, 2017, the Security Council of the State Council convened a video conference on comprehensive electrical fire management work, and decided to organize and implement a comprehensive electrical fire management work for a period of 3 years (May 2017-April 2020).
    C. Since the recent period, fire protection units in various provinces and cities (Beijing, Zhejiang, Jiangsu, Guizhou, etc.) have successively issued the "Notice on Actively Promoting the Implementation of the Electrical Fire Monitoring System" or held special meetings to urgently deploy and supervise units to install electrical fire monitoring devices. It is required to earnestly improve the ability to prevent electrical fires and reduce the occurrence of electrical fires.

    4. Government policy support
