AI Technical Summary
Existing electricity meters have poor anti-theft performance, simple protective structure, independent operation of protective components, imperfect alarm mechanism, inability to effectively identify various illegal operations, inconvenient inspection and maintenance, and affect maintenance efficiency.
It adopts a double-layer protective structure with an outer cover and an internal protective device. The protective components work together through a double-plate linkage opening and closing mechanism. The direct linkage design between the safety bolt and the alarm button, combined with a unique sliding plate unlocking mechanism, allows maintenance to be completed without special tools during legal operation.
Significantly improves anti-hacking capabilities, enhances protection effectiveness, ensures timely detection of unauthorized operations, optimizes maintenance channel design to improve maintenance efficiency, and provides clear status indicators for easy troubleshooting.
