地处10多家水泥生产企业重重“包围”之中的500千伏徐州至上海超高压输电线路9号塔,由于长年遭受烟尘灰粉的污染侵袭,近年来,曾多次出现高压玻璃绝缘子大面积自爆现象,仅去年夏季就造成三次被迫停运,给国家的电力生产和输送安全造成严重影响。因此,经国电公司特批,自5月30日至6月2日18点,该处的768片玻璃绝缘子将全部更换成为抗污染性特强的陶瓷绝缘子。担此重任的徐州供电公司充分依靠其在全国首创的带电更换四联串耐张绝缘新技术,顶烈日争分夺秒,斗风雨顽强奋战。于6月2日上午10时30分,提前圆满完成任务,确保了国家电力主动脉安全运行,为上海及苏锡常等地区的经济发展建设和人民群众生活用电安全,作出了贡献。图为该公司员工正在高空更换绝缘子。
Located in more than 10 cement manufacturers heavy “encirclement ” among the 500 kV Xuzhou to Shanghai EHV transmission line tower No. 9, due to long-term exposure to soot dust pollution in recent years, there have been many high-pressure Large-scale self-blasting of glass insulators resulted in three outages only last summer, which severely affected the country’s electricity production and transportation safety. Therefore, the State Power Corporation approved the special, from May 30 to June 2 at 18 o’clock, where the 768 glass insulators will be fully replaced with a strong anti-pollution ceramic insulators. Xuzhou power supply company responsible for this task fully rely on its first in the country to replace the four-string live-loaded insulation of new technologies, top competition day by minute, tough fight. At 10:30 on June 2, the successful completion of the task ahead of schedule to ensure the safe operation of the national power aorta, for Shanghai and Wuxi, Wuxi and other areas of economic development and construction of people’s lives and electricity safety. The picture shows the company’s employees are replacing the insulator at high altitude.
