Electric energy metering device with plastic dipping structure Technical Field The utility model relates to the technical field of electric energy metering equipment, in particular to electric energy metering with a plastic dipping structure. Background The electric energy metering device occupies an extremely critical position in the electric power system, and the accuracy of the electric energy metering device directly relates to the economic accounting and fair transaction of the electric power production, supply and use links. From the early heavy electric energy meter based on the electrolysis principle, the electronic electric energy meter which is integrated with the electronic technology, has high precision and multiple functions is developed, and the electric energy metering device is continuously updated. Along with the construction of a novel power system, a large number of new energy, micro-grid and Internet of things interaction equipment are connected, so that higher requirements are put forward for the electric energy metering device, electric energy is precisely metered, and stable operation is required under a complex environment so as to meet the requirement of energy business diversification. In practical application scenarios, there are a number of problems with existing electrical energy metering devices. On one hand, the difficult problem of heat dissipation is more prominent. The meter continuously generates heat in the working process, if the meter cannot timely and effectively emit heat, the internal temperature is too high, the performance of electronic elements is further reduced, metering errors are generated, and the service life of equipment is even shortened. For example, some traditional electric energy metering devices only rely on natural heat dissipation, the heat dissipation efficiency is low, and in a high-load working state, the temperature of equipment rises sharply, so that the metering accuracy is seriously affected. On the other hand, the dust-proof performance is poor. Impurities such as dust easily enter the interior through gaps and openings of the device, adhere to the surface of an electronic element, accumulate to a certain extent to influence the heat dissipation of the element, possibly cause faults such as short circuit and the like, and increase equipment maintenance cost and fault risk.
