基于风险概率的电力变压器设备风险评估技术研究

摘要

随着我国经济的持续增长,电网向着智能化、远距离、特高压方向发展.为了进一步提高电力变压器运行检修质量,保证电网安全稳定运行,在实验室和现场试验的基础上,结合国外的有关资料,对变压器设备风险评估技术进行了研究,分析了电力变压器的故障模式,搜集反映设备风险的本地化可用信息,提出了电网企业对现场电力变压器设备进行风险评估的方法.%As China's economy continues to grow, power grids are getting more intelligent, long-distanced, and of higher voltages. To further improve the operation and maintenance quality of power transformers and to ensure the safety of power grids, this paper, based on both laboratory and field tests together with relevant information from other countries, conducts a study on the risk assessment technology for power transformers. Through analyzing power transformer fault modes and collecting the useful information for the equipment risk available locally, this paper proposes an on-site risk assessment method of power transformers for power companies.
