[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] See also Figure 1-5 The present invention provides a technical solution: an intelligent safety electricity protector, comprising a shell 1, an alarm light 2 is fixedly connected to the shell 1, two groups of alarm lights 2 are provided, the alarm lights 2 are used for alarm prompts, a display screen 3 is fixedly connected to the shell 1, a smart electricity management chip is provided in the display screen 3, and advanced power management technology is adopted to reduce losses and save energy, and smart remote control and other functions can be realized through the mobile phone end to realize remote data monitoring of the product, send remote control instructions, real-time detection of equipment output voltage, current, total load power, insulation resistance and temperature to ground, etc., and real-time display parameter information, setting information and fault alarm information, etc. are displayed through the display screen 3.

[0018] A handle is fixedly connected to the top of the housing 1 to facilitate moving and installing the power protector.

[0019] like Figure 2 and 3 As shown, the shell 1 is fixedly connected with electrical components that cooperate with each other, such as an air switch, a surge protector, a leakage protection device, an overload protector and an overvoltage protector. The air switch is used to provide overcurrent protection; the surge protector is used to withstand the large current and high-energy surge energy absorption of lightning and induced lightning strikes; the leakage protection device can send a signal when the electrical equipment leaks or when someone is electrocuted, before physical harm occurs, and the low-voltage circuit breaker quickly cuts off the power supply; the overload and overvoltage protectors are used to calculate and set the current and voltage action values ​​according to their rated powers. When the equipment and line fault current and voltage reach the action values, the protection is delayed tripping, thereby achieving the effect of precise overload and overvoltage protection.

[0020] Fins 4 are fixedly connected to both sides of the shell 1. The fins 4 are arranged in several groups at an angle. A flow channel 5 is arranged below the fin 4. The flow channel 5 is fixed to the inner wall of the shell 1. A metal sheet 6 is embedded at the bottom of the flow channel 5. The metal sheet 6 is connected to the power supply by wires and is connected in parallel with the power protector body. There is a gap between the two groups of metal sheets 6. The fins 4 are used for heat exchange of the shell 1. When the humidity inside the shell 1 is high, the moisture in the air is condensed into water droplets on the fins 4, and then flows to the metal sheet 6 at the bottom through the flow channel 5. Since water is conductive, the two groups of metal sheets 6, the wires and the power supply form a loop to cause a short circuit, which causes the power protector to trip instantly and cut off the power supply of the line, thereby avoiding safety hazards caused by long-term use of the power protector in a humid environment.

[0021] A liquid storage tank 7 is provided at the bottom of the flow channel 5, and the liquid storage tank 7 is fixedly connected to the shell 1 and the flow channel 5. A water-absorbing material is provided inside the liquid storage tank 7. When the water droplets above the two groups of metal sheets 6 are large enough, the water droplets fall down and are absorbed by the water-absorbing material, thereby improving the safety of the use of the electrical protector.

[0022] It should be noted that the flow channel 5 is made of non-metallic material, and the surfaces of the fins 4 and the flow channel 5 inside the shell 1 are coated with hydrophobic material, so that water droplets formed on the surfaces of the fins 4 and the flow channel 5 are difficult to adhere to, which facilitates the formation of a short-circuit loop. At the same time, it can also avoid long-term adhesion of water droplets, which may cause electrochemical reactions on the fins 4 to cause rust or corrosion, thereby reducing the service life of the fins 4.

[0023] like Figure 1 , Figure 4 and Figure 5 As shown, air holes 8 are provided on both sides of the shell 1 , and the air holes 8 are used to facilitate gas exchange inside the shell 1 . The air holes 8 are located below the fins 4 .

[0024] A ventilation fan is arranged in the shell 1, and the ventilation fans include ventilation fan 1 9 and ventilation fan 2 10. A support frame is fixedly connected to the inside of the shell 1. Ventilation fan 1 9 is arranged above the support frame, and ventilation fan 2 10 is arranged at the bottom of the shell 1. A baffle door 11 is hinged at the bottom of the shell 1. Ventilation fan 1 9 is used for internal gas circulation, and ventilation fan 2 10 is used for discharging internal gas. The baffle door 11 is used to prevent large objects from entering the shell 1 and causing damage to the internal circuit. Large objects include snakes, insects, rats, and ants.

[0025] like Figure 2 and Figure 4 As shown, a humidity sensor 12 and a temperature sensor 13 are fixedly connected inside the shell 1. The humidity sensor 12 is arranged above the inside of the shell 1 and is used to detect the humidity inside the shell 1. Four groups of temperature sensors 13 are arranged, which correspond to the air switch, surge protector, leakage protection device, overload protector and overvoltage protector fixedly connected inside the shell 1, and are used to measure the temperature of electrical components when they are in use.

[0026] A protection system is also provided in the display screen 3, and the protection system includes an acquisition module, a control module and an alarm module. The acquisition module is electrically connected to the humidity sensor 12 and the temperature sensor 13, and is used to collect temperature data and humidity data and calculate the temperature difference. The control module is electrically connected to the ventilation fan 1 9 and the ventilation fan 2 10, and is used to control the start of the ventilation fan 1 9 and the ventilation fan 2 10 to perform targeted ventilation inside the shell 1. The alarm module is electrically connected to the alarm light 2, and is used to provide abnormal alarm prompts and feedback to the mobile phone.

[0027] Power protection method of power protector: Step 1: Collect module temperature data for analysis and feed it back to the protection system.

[0028] Specifically, the acquisition module acquires the actual temperatures measured by the four groups of temperature sensors 13 corresponding to the electrical components, and the acquisition module is internally provided with temperature limits and temperature difference limits.

[0029] When the actual temperature measured exceeds a set and reaches the temperature limit, feedback is sent to the alarm module for an alarm prompt, and the power supply of the line is cut off by the power protector. At the same time, feedback is sent to the control module, and the control module controls the ventilation fan 1 9 and the ventilation fan 2 10 to start, and air is introduced into the shell 1 to promote gas circulation and quickly cool down to prevent the electrical components from causing a fire due to overheating.

[0030] When the actual temperatures measured by the four groups of temperature sensors 13 do not reach the temperature limit, the acquisition module calculates the maximum difference of the four groups of temperatures. If the maximum temperature difference reaches the temperature limit, there is an abnormal increase in the temperature of the electrical components, which is fed back to the control module. The control module controls the ventilation fan 9 to start, promotes internal gas circulation, and reduces the internal temperature. Whether the control module controls the ventilation fan 2 10 to start needs to be supplemented by judging in combination with the humidity conditions.

[0031] If the maximum temperature difference does not reach the temperature limit, the temperature of the electrical component is normal and internal gas circulation is not performed. Whether the control module controls the ventilation fan 210 to start needs to be supplemented by combining the humidity conditions.

[0032] Step 2: The collection module collects humidity and makes additional judgments.

[0033] Specifically, the collection module collects the actual humidity inside the housing 1 , and the collection module is also provided with a humidity limit value.

[0034] When the actual humidity RH reaches the humidity limit, it is fed back to the alarm module for an alarm prompt, and at the same time fed back to the control module, the control module controls the ventilation fan 2 10 to start, promote the internal and external air circulation, and quickly reduce the internal air humidity. While exchanging heat, the fins 4 use the temperature difference between the inside and the outside to make the moisture in the air liquefy into water droplets on the fins 4, flow through the flow channel 5 to the metal sheet 6 at the bottom, and then use the conductive property of water to cause a short circuit with the two sets of metal sheets 6, wires and power supply loops, so that the power protector instantly trips and cuts off the power supply of the line, avoiding the safety hazard of the power protector being used in a humid environment for a long time, and at the same time avoiding the situation where the humidity inside the shell 1 cannot be reduced by ventilation in a humid environment.

[0035] When the actual humidity does not reach the humidity limit, it is a normal situation, and the control module does not control the ventilation fan 2 10 to perform ventilation operation.

[0036] Through the above steps, the temperature of the electrical components can be detected to avoid fire caused by excessive temperature. At the same time, the internal humidity can be detected and the temperature difference between the humidity and the heat exchange of the fins 4 can be used to liquefy the water into water droplets, actively forming a short circuit, thereby avoiding the life of the electrical protector being reduced due to being in a humid environment for a long time, thereby creating a safety hazard.
