ITER脉冲变电站镍镉蓄电池间通风设计

The ventilation design of nickel-cadmium batteries room for the ITER PPEN substation

根据位于法国卡达拉舍地区ITER(国际热核聚变实验堆)项目现场的自然条件情况以及对蓄电池间温度、氢气排放的具体要求,采用在蓄电池间用风机排风,以全新风空调送风的设计方案,实现对蓄电池间的通风换气,使镍镉蓄电池在适合的环境下运行,减少电池的故障率,保障UPS、DC系统稳定运行。

ITER project site is located in Cadarache,France.According to local natural conditions at the site of ITER project,and the specific requirements for battery cell temperature and hydrogen emissions,a new method of ventilation is adopted.The battery room adopts fan exhaust,air-conditioner supply fresh air.The ventilation of the battery room is realized,so that the nickel-cadmium battery can operate in a suitable environment.Therefore,the failure rate of the battery is reduced to ensure the stable operation of UPS and DC systems.
