Abstract

The invention provides an electric power metering box, and belongs to the technical field of electric power equipment.The two adjacent side walls of one side of a box body are provided with installation openings, two baffles are connected into the installation openings, the outer wall of the box body is fixedly connected with a motor, the tail end of an output shaft of the motor penetrates through the box body and is connected with a fan, the box body is provided with heat dissipation holes, and a driving cavity is formed in the top end of the box body; a driving pipe is fixedly connected into the driving cavity and can drive the two baffles to rotate in the mounting opening. Automatic opening of the two baffles is completed through cooperation of the gear and the toothed plate, the ventilation area is increased, the heat dissipation efficiency is improved, and stability of electric appliances in the box body is guaranteed; after the two baffles are completely opened, the two first magnetic blocks attract each other, and it is guaranteed that the baffles are opened stably; the closing process of the two baffles is accelerated, and the stability of the closing state of the baffles is guaranteed; the technical problem of how to accelerate internal heat dissipation when the temperature in the electric power meter is relatively high is solved.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to an electric power metering box. Background technique [0002] Electricity metering box can measure the usage of electricity in the circuit. Electricity meter is a kind of electric metering box. It is widely used and has the advantages of high measurement accuracy, light weight, convenient installation, and anti-theft of electricity. [0003] In electric places with high power consumption, not only electric power measurement devices are installed in the electric power metering box, but also various detection devices, signal transmission devices, etc. are connected in series, which can monitor the actual situation in the box through the network in real time. During the process of increasing the current in the metering box, the equipment in it will continue to emit heat, and the cooling method through the fan exhaust air in the box is limited, which cannot effective...
