摘要:
动车组高速运行时,在落弓状态下受电弓受气流影响可能会被吹起,进而可能导致短接接触网故障。为评估落弓状态下受电弓的气动性能,保障受电弓的服役性能及安全高效运营,在兰州至乌鲁木齐客运专线搭载 CRH2G 动车组进行了大风条件下落弓状态的受电弓空气动力学试验研究。试验结果表明,受电弓受到的气动抬升力远小于落弓保持力,不存在由于气流作用而引起受电弓被动升弓危险。
Abstract:
When EMUs run at a high speed, the pantograph would be affected by airflow and blown up in dropping status, which would result in catenary short-circuit fault. In order to evaluate the pantograph aerodynamics characteristics in dropping status and ensure pantograph performance and safety operation, pantograph aerodynamics experimental research in dropping status under strong wind condition for the Lanzhou to Wulumuqi passenger railway CRH2G EMUs was carried up. The experimental results indicated that the pantograph blowing up force was far less than the dropping holding force, so the passive rising pantograph risk because of airflow action couldn’t exist.
