| 高压支柱绝缘子结构特点 Structural characteristics of high pressure strut insulators 零值自破、便于检测钢化玻璃绝缘子具有零值自破的特点。只要在地面或在直升机上观测即可，无需登杆逐片检测，降低了工人的劳动强度。 The zero value is self broken, so that the toughened glass insulators are easy to detect. As long as we can observe it on the ground or on a helicopter, we do not need to check the rod by piece, and reduce the labor intensity of the workers. 引进生产线的产品，年运行自破率为0.02—0.04%，可以节约线路的维护费用。耐电弧和耐振动性能好 The products imported from the production line are running at 0.02 to 0.04% per year, and the maintenance cost of the line can be saved. Good arc resistance and vibration resistance 在运行中玻璃绝缘子遭受雷电烧伤的新表面仍是光滑的玻璃体，并有钢化内应力保护层，因此，它仍保持了足够的绝缘件能和机械强度。 In operation, the new surface of the glass insulator is still a smooth vitreous body and has a tempered inner stress protective layer, so it still maintains sufficient insulation and mechanical strength. 在500kv线路上多次发生导线履冰引起舞动的灾害，受导线舞动后的玻璃绝缘子经测试，机电性能没有衰减。 On the 500kV Line, the galloping caused by conductor ice has occurred many times. The electrical and mechanical properties of glass insulators after galloping are tested. 自洁性能好和不易老化 Good self cleaning and not easy to aging 据电力部门普遍反映玻璃绝缘子不易积污和易于清扫，南方线路运行的玻璃绝缘子雨后冲洗得较干净。 According to the electricity sector, glass insulators are generally not easily contaminated and easy to clean. The glass insulators running on the southern line are washed more cleanly after rain. 对典型地区线路上的玻璃绝缘子定期取样测定运行后的机电性能，从积累上千个数据表明运行35年后的玻璃绝缘子的机电性能与出厂时的基本一致，未出现老化现象。 The mechanical and electrical properties of the glass insulators on the lines of the typical areas are regularly sampled and measured. The mechanical and electrical properties of the glass insulators after 35 years of operation are basically the same as that in the factory, and there is no aging phenomenon. 主容量大，成串电压分布均匀，玻璃的介电常数7-8，使钢化玻璃绝缘子具有较大的主电容和成串的电压分布均匀，有利于降低导线侧和接地侧附近绝缘子所承受的电压，从而达到减少无线电干扰、降低电晕损耗和延长玻璃绝缘子的寿命的目的，运行实践证明了这一点。 The main capacity is large, the distribution of the series voltage is uniform, the dielectric constant of the glass is 7-8, which makes the tempered glass insulators have a larger main capacitance and a series of voltage distribution. It is beneficial to reduce the voltage of the insulators near the wire side and the ground side, thus reducing the radio interference, reducing the corona loss and prolonging the glass insulation. The purpose of life of children is proved by operation practice. |
