AI Technical Summary

Technical Problem

The covers of existing metering boxes are prone to loosening or falling off under the influence of external forces such as strong winds or vibrations, and the traditional fixing method is cumbersome to operate, affecting the stability of power grid operation and maintenance efficiency.

Method used

The enclosure and lid are designed with hinged columns for rotational connection. Combined with a rounded transition structure, plug-in locking blocks, and edge positioning components, a multi-directional constraint anti-detachment structure is formed. At the same time, the heat dissipation bosses and the distribution of the hinged column array are used to improve impact resistance and heat dissipation efficiency.

Benefits of technology

It effectively prevents the lid from falling off, improves the impact resistance and heat dissipation efficiency of the metering box, simplifies the maintenance process, and is especially suitable for outdoor emergency maintenance scenarios.
