蓄电池组50%放电核容法在宁波轨道交通的应用

Application of 50%Discharge Core Capacity Method in Ningbo Rail

近年来各地区城市轨道交通发展突飞猛进,许多大城市轨道交通已成为市民出行的首选交通工具。随着地铁运营里程的增加,带给市民出行便利的同时,安全运营也备受关注。宁波轨道交通运营公司结合当下UPS系统及阀控式铅酸蓄电池组在本公司的应用发展,根据阀控式铅酸蓄电池组核容校验要求,考虑实际工作情况,采用新方式——50%放电核容法,并从试验可靠性、安全性等方面对蓄电池组核容技术在宁波轨道交通应用的可行性进行了分析与实践。

In recent years,the development of urban rail transit in various regions has made rapid progress,and rail transit in many large cities has become the preferred means of transportation for citizens.With the increase of subway operation mileage,while bringing convenience to citizens,safe operation has also attracted much attention.Ningbo Rail Transit combines the current UPS system and valve-regulated lead-acid battery pack in the company’s application and development,combined with the valve-regulated lead-acid battery pack nuclear capacity verification requirements,and considers the actual working conditions,and adopts a new method—50%discharge core The feasibility of the application of battery pack nuclear capacity technology in Ningbo rail transit is analyzed and practiced from the aspects of test reliability and safety.
