摘要
为解决大型水电站储油柜传统胶囊高压变形、老化渗漏等问题,文章以某百万千瓦级水电站12 m3储油柜为研究对象,开展胶囊创新设计。采用“增强层–密封层–缓冲层”仿生复合结构,结合自适应压力调节与耐环境老化优化设计,实现与原设备无缝适配。应用结果表明,胶囊最大变形量不大于3%,密封渗漏量为0;绝缘油介损值稳定在0.02%~0.03%,劣化速率降低70%,更换周期延长至8 a;使用寿命达15 a以上,单台设备年省运维成本12万元。可为水电站关键设备安全稳定运行提供可靠技术保障。
In order to solve the problems of traditional capsule high-pressure deformation,aging and leakage in large hydropower station oil storage tanks,this paper takes a 12 m³oil storage tank of a million kilowatt hydropower station as the research object and carries out innovative capsule design.Adopting a biomimetic composite structure of“reinforcement layer sealing layer buffer layer”,combined with adaptive pressure regulation and optimized design for environmental aging resistance,seamless adaptation with the original equipment is achieved.The application results show that the maximum deformation of the capsule is ≤3%,and the sealing leakage is 0;The dielectric loss value of the insulating oil remains stable at 0.02%-0.03%,the degradation rate is reduced by 70%,and the replacement cycle is extended to 8 years;The service life is over 15 years,and the annual maintenance cost of a single device is reduced by 120000 yuan,providing reliable technical support for the safe and stable operation of key equipment in hydropower stations.
