摘要
提出了一种应用于光伏并网的专用低压断路器,该装置在原有低压断路器功能基础上,增加了失压跳闸和检有压合闸等功能,并通过合理设置功能参数,能够实现最大限度支持光伏并网发电和确保光伏发电安全的目的。对专用断路器的设计原理、工作条件、试验内容及要求等作出了详细说明。实际运行结果表明,该装置达到了预期设计目的。
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.
