Technical Field
[0001] The utility model specifically relates to a ventilation type electric energy metering box. Background Art
[0002] With the development of the electricity market and the increase in electricity users, the demand for energy metering and management is growing. Energy metering must not only be accurate but also ensure the long-term stable operation of equipment. Consequently, energy meter boxes have emerged. Their primary function is to accurately measure, record, and calculate energy consumption, enabling power suppliers to bill users for their consumption. They also facilitate monitoring and management of power system operations. They are commonly used in residential, commercial, and industrial facilities.
[0003] Inside the energy meter box, heat is generated when current flows through the meter and other control devices. If this heat cannot be effectively dissipated, the equipment's operating efficiency and safety will be affected. Traditional energy meter boxes often use a closed design. While dustproof and waterproof, this hinders heat dissipation and easily causes the temperature inside the box to rise. This not only affects the meter's accuracy but can also shorten the lifespan of electrical components.
[0004] Therefore, it is necessary to invent a ventilation type electric energy metering box to solve the above problems. Utility Model Content
