In the process of rural power grid renovation, upgrading and renovating old split meter ready boards is crucial. In the past, rural split meter ready boards often used rubberwood switches, which had a single function and only had basic circuit breaking capabilities, lacking effective protection mechanisms. Once there are faults such as overload or short circuit in the circuit, the rubber switch cannot cut off the current in a timely manner, which can easily cause electrical fires and threaten the safety of rural residents' lives and property. At the same time, the operation of laminated wood switches is inconvenient and requires manual on-site operation, making it difficult to achieve remote monitoring and management, which increases the cost and difficulty of operation and maintenance.

With the development of smart grids, smart circuit breakers have emerged, bringing revolutionary changes to the renovation of old rural split meter ready boards. The intelligent circuit breaker integrates real-time monitoring, remote control, and multi-layer protection functions. It can monitor parameters such as current, voltage, and power in real time. Once abnormal conditions such as overload or short circuit are detected, the circuit will be quickly cut off, effectively avoiding the expansion of the fault.

Intelligent circuit breakers support remote opening and closing, timed control, and local/remote locking operations. The power department can monitor the real-time operation status of the split meter ready board through a remote monitoring system, achieving intelligent management. In addition, it can also record alarms, faults, and operational events, making it easy for users to analyze and locate problems.

The transformation from laminated wood switches to intelligent circuit breakers not only improves the reliability and safety of rural power grid supply, but also reduces operation and maintenance costs and improves management efficiency. This renovation project is of great significance for improving the living conditions of rural residents and promoting rural economic development, and is a key measure to promote rural modernization construction.
