Description

Electric energy metering box with heat dissipation waterproof sealing structure Technical Field The invention belongs to the technical field of power equipment, and particularly relates to an electric energy metering box with a heat dissipation waterproof sealing structure. Background The electric energy metering box is a special box body for installing and protecting an ammeter and related matched equipment used in daily life. Due to the layout of the power supply lines and the requirements of the actual use environment, a large number of electric energy metering boxes are installed directly in an open air environment. In order to ensure that electronic components in the electric energy metering box can normally dissipate heat, operators usually set heat dissipation holes on the upper side and the lower side or on the two sides of the box body, and the box body is formed to naturally flow to take away heat by utilizing the principle that hot air rises and cold air falls. However, when the electric meter or the switch is in rainy days, strong air flow is usually accompanied in the weather, the radiating holes are simply opened, and rainwater is extremely easy to blow into the box body by wind, so that the electric meter or the switch is wetted and short-circuited, and even safety accidents are caused. If the positions of the inner vent and the outer vent are staggered to form a staggered channel, the risk of rainfall entering the box body can be reduced, but the difficulty of air flow discharge in the box body is increased, so that the heat dissipation efficiency of the box body is influenced (more serious in high-temperature weather).
