我所承担了引进的30万千瓦和60万千瓦火电发电成套设备中“电机锥壳”的研制任务。用玻璃钢(GFRP)制造“锥壳”,除力学、绝缘性能等达到要求外,还严格要求控制“锥壳”的轴向和径向的线膨胀系数变化范围。为此,我们对GFRP平均线膨胀系数的测试方法进行了研究。 I assumed the introduction of the 300,000 kilowatts and 600,000 kilowatts of thermal power generation complete sets of equipment in the “motor cone shell” research and development tasks. Made of FRP (GFRP), “cone shell”, in addition to mechanical, insulation properties to meet the requirements, but also strictly required to control the “cone shell” axial and radial linear expansion range of variation. To this end, we test the GFRP average linear expansion coefficient of the test method.
