[0002] The low-voltage intelligent meter box is a device used to measure and meter electric energy in the power supply system. It is usually installed in a low-voltage distribution box or an outdoor distribution cabinet to monitor and record the consumption of electric energy. The emergence of the low-voltage intelligent meter box makes the electric energy metering more intelligent and automated, and brings convenience and benefits to the management and optimization of the power system. It is generally known that the low-voltage intelligent meter box is generally installed outdoors, and the front face (and box door) of the low-voltage intelligent meter box is provided with a glass viewing window. However, when the low-voltage intelligent meter box is installed outdoors, the sunlight will shine into the meter through the glass viewing window, which will accelerate the loss of the electrical components and connecting wires inside the meter box. Especially after rain, the sunlight will be refracted by the water droplets condensed on the glass of the viewing window, which has a certain magnifying glass effect, and may cause greater damage to the electrical components and connecting wires inside the meter box. Therefore, the present application proposes a low-voltage intelligent meter box protection device. Utility Model Content
