Problems solved by technology

[0002] 1. The traditional air switch senses the magnitude of the current physically, and controls the mechanical shrapnel switch through the current conductor to cut off the power. The traditional air switch has very weak perception of current and residual current when there is weak leakage or electric shock, so these two types Under such circumstances, it is extremely difficult for the air switch to automatically cut off the power, which cannot effectively solve the occurrence of electric shock casualties;

[0003] 2. Lack of detection of wire temperature, lack of calculation and judgment of power when all electrical appliances in the home are turned on, temperature rise caused by wire overload will also lead to electrical fires in the home, and the air switch cannot solve this problem;

[0004] 3. The traditional air switch is completely mechanically controlled, lacks the function of material network, and cannot realize linkage with other fire detection equipment, especially in the case of a home fire that needs to be powered off, the traditional air switch cannot meet the requirements of timely power off;

[0005] 4. The traditional air switch cannot realize the detection voltage, no matter the voltage is high or low, it will only work in a fixed manner. When the voltage is unstable, it is necessary to install a voltage stabilizer at the lower end of the power line to achieve voltage stabilization. It cannot solve the problem of electrical burnout when the voltage fluctuates. hidden dangers;

[0006] 5. The traditional air switch does not have the function of remote power-off, and the continuous power-on operation of household appliances will also cause fire hazards. The lack of remote power-off function will make household electricity use less controllable, and users cannot quickly power off independently;

[0007] 6. At present, the leakage and electric shock in the home are mostly solved by the leakage protector, but the data of the leakage protector is fixed due to the different consumption of the household line. It is convenient and cannot be used in conjunction with the air switch. At present, there is an air switch integrated with the leakage protector and the air switch, but it cannot effectively detect the weak leakage. time, the health and safety of the electric shock personnel cannot be effectively protected, and there is still the possibility of death;

[0008] 7. At present, the equipment that can realize electrical fire detection in the home is large in size and cannot be installed in the home distribution box. Even if it is installed, it cannot reduce the number of original air switches. Correct installation takes a long time to install, and the function and fault self-testing of accessories cannot be realized;

[0009] 8. The existing technology detects electrical circuit data using external current transformers, residual current transformers, temperature sensors and other equipment, which are large in size and difficult to integrate and install in a small device and realize the corresponding data collection function
