摘要
通过计算变压器低压侧出口短路电流值,给出光伏升压预装式变电站中低压断路器分断能力的选择与配合方法,为行业内工程设计人员进行产品选型设计提供理论依据。
By calculating the outlet short-circuit current of low voltage side of transformer,the selection and cooperation method of the breaking capacity of the medium-low voltage circuit breaker in the photovoltaic booster prefabricated substation was provided,which provided the theoretical basis for the engineering design personnel in the industry to carry out product selection and design.
