AI Technical Summary
Existing single-phase electricity meters cannot be effectively limited and fixed during cable installation, making electricity theft operations inconvenient and unable to be prevented from being cut off in time.
A device for preventing electricity theft in a single-phase smart energy meter was designed. The cable is fixed by limiting the limit plate and the compression bolt structure. The device automatically cuts off the power when a short circuit occurs during electricity theft. The short circuit is generated by the contact between the limit block and the electrode block to automatically trip and cut off the power.
It achieves effective cable fixing and rapid power-off protection, prevents electricity theft, and improves the safety and protection capabilities of the electricity meter.
