玻璃绝缘子玻璃件内部含有杂质颗粒

产品质量原因主要是玻璃绝缘子玻璃件内部含有杂质颗粒,最常见的是NIS颗粒。NIS在玻璃件熔制、退火过程中相变状态不完全,在绝缘子投入运行后认为缓慢相变、发生膨胀,导致玻璃内部产生裂纹。
The main reason for product quality is that the glass parts of glass insulators contain impurity particles, the most common is NIS particles. The phase transformation state of NIS is incomplete in the process of glass melting and annealing. After the insulator is put into operation, it is considered that the slow phase transformation and expansion will cause cracks in the glass.
当颗粒杂质的直径小于一定值,可能无法通过冷热冲击予以剔除,导致运行中绝缘子自爆率过高。杂质颗粒位于玻璃件的内部张应力层时,产生自爆的概率更高,因玻璃本身是一种脆性材料,耐压但不耐拉,所以玻璃的大部分破碎是张应力引发的。
When the diameter of particle impurities is less than a certain value, it may not be eliminated by thermal and cold shock, resulting in high self-explosion rate of insulators in operation. When the impurity particles are located in the internal tension stress layer of the glass, the probability of self-explosion is higher. Because the glass itself is a brittle material, it can withstand pressure but not tension, so most of the breakage of the glass is caused by tension stress.
