摘要
随着全球极端气候的频发,研究复合绝缘子金具与芯棒压接部位是否适应极端气温的变化,具有重要的工程价值。本文采用液氮冷却模拟极寒气温,热水加热模拟极热气温的方法对复合绝缘子压接接头模拟极端气温力学试验分析,验证了其安全裕度。
With the frequent occurrence of global extreme climate,it is of important engineering value to study whether the crimping parts of composite insulator fittings and core rod adapt to the changes of extreme temperature.In this paper,the liquid nitrogen cooling method is adoptde to simulate extreme cold temperature and the hot water heating method is adopted to simulate extreme hot temperature with which the mechanical test analysis of the composite insulator crimping joint is performed and its safety margin is verified.
