Description

Environment-friendly and energy-saving intelligent electric energy metering box Technical Field The application relates to the technical field of electrical equipment, in particular to an environment-friendly and energy-saving intelligent electric energy metering box. Background In the technical field of electrical equipment, the development of an electric energy metering box is of great importance, and the electric energy metering box is one of key equipment for guaranteeing accurate metering and stable operation of an electric power system. With the continuous development of the power industry, the performance requirements on the electric energy metering box are increasingly improved, so that the metering accuracy is ensured, and the adaptability and the reliability of the electric energy metering box under different environments are considered. Meanwhile, the environment-friendly and energy-saving concept is deep, so that the electric energy metering box is more focused on the efficient utilization of energy and the environmental protection in the design and use processes. The electric energy metering box with excellent performance can effectively reduce power loss, improve the operation efficiency of a power system and bring remarkable economic benefits to power users and power supply enterprises. Conventionally, various means have been generally employed for solving the problems of heat dissipation and power supply of an electric energy meter box. For the heat dissipation problem, a fixed ventilation opening is formed in the box body, and air exchange is realized by means of natural wind flow, so that heat generated in the box body is taken away. In addition, a heat radiation fan at a fixed position is arranged in the box body, and the air flow is accelerated through the operation of the fan, so that the heat radiation effect is enhanced. In terms of power supply, the conventional electric energy metering box mainly relies on commercial power to supply power so as to maintain normal operation of internal equipment. The power supply mode is relatively stable, but the limitation of the power supply mode is gradually displayed in remote areas or under the scenes of strict requirements on energy consumption. However, these existing approaches have significant drawbacks. The heat dissipation mode of the fixed ventilation opening is greatly influenced by natural environment factors, and the heat dissipation effect is often poor under the condition of unsmooth air circulation or higher air temperature, so that the requirement of equipment in the box body on temperature is difficult to meet. Although the radiating efficiency of the fixed-position radiating fan can be improved to a certain extent, the radiating fan cannot conduct targeted radiating according to the temperature changes of different positions in the box body, local overhigh temperature is easily caused, and the normal operation and the service life of equipment are affected. The mode of simply relying on the mains supply not only increases the energy consumption and the operation cost, but also can influence the normal operation of the electric energy metering box under the condition of unstable mains supply.
