Dedicated Low Voltage Circuit Breaker Used in Photovoltaic Generation System

This paper put forward a grid-connected photovoltaic dedicated low voltage circuit breaker. Based on the original low voltage circuit breaker function, the device increases the loss of voltage tripping and closing test pressure and other functions, and by reasonably setting the function parameters, it can achieve the maximum support to photovohaic power generation and ensure the safety of photovohaic power generation. The design principle, working conditions, test content and requirements of the dedicated circuit breaker were described in detail. The actual operation result shows that the device can achieve the aim of design.
