摘　　要：论述直流1500V接触轨系统的安全性,包括系统安全、设备安全、人身安全。通过故障模式后果分析法,对1500V接触轨系统的可靠性进行分析。在对国内外相关规范要求分析的基础上,认为不管是直接接触防护还是间接接触防护,对于人身安全防护标准而言,直流1500V接触轨系统与直流750V接触轨系统是一致的。同时,就涉及1500V接触轨设备自身安全的绝缘距离和爬电距离提出技术要求。阐述直流1500V接触轨系统的安全防护策略,并相应采取一系列安全防护措施。The safety of DC 1500V conduct rail system includes system safety,equipment safety and personnel safety. The reliability of DC 1500V conduct rail system was analysed by failure mode consequences method. Based on the analyses according to domestic and overseas codes,it was concluded that the protective standards for personnel safety are the same both for DC 1500V conduct rail system and DC 750V conduct rail system,irrespective of whether the contact protection is direct or indirect. The technical requirements on insulated distance and creep distance related to equipment safety of DC 1500V conduct rail system are put forward. Authors also expound the safety protective strategy for DC 1500V conduct rail system together with a series of protective provisions.
