| 支柱绝缘子是一种特殊的绝缘控件，能够在变电站设备中起到重要作用，它既作为对设备带电部分的支撑，又可发挥良好的绝缘效果，变电站内设备的支柱绝缘子通常由陶瓷制成。为提高支柱绝缘子安全运行的可靠性和确保支柱绝缘子的产品质量，国家电网公司颁布了《高压支柱瓷绝缘子现场检测导则》Q/GDW 407一2010，明确规定电网中所使用的支柱绝缘子应在安装前逐只进行超声波探伤检测。超声波探伤部位为支柱绝缘子的上、下端与法兰连接口处，探伤范围为绕绝缘子一周，探伤内容为爬波、纵波检测。 Pillar insulator is a special insulating control, which can play an important role in substation equipment. It not only supports the live part of equipment, but also plays a good insulating effect. The pillar insulator of substation equipment is usually made of ceramics. In order to improve the reliability of the safe operation of the pillar insulators and ensure the quality of the pillar insulators, the State Grid Corporation pwww.apsaLu.cn www.hunLiaoji.com.cn www.jnkeqing.cn www.hanyubw.cowww.ccdrc.cn www.bjguomei.cnromulgated the Guidelines for Field Inspection of High Voltage Pillar Porcelain Insulators Q/GDW 407-2010, which clearly stipulates that the pillar insulators used in the power grid should only be tested by ultrasonic wave before installation. The location of ultrasonic inspection is the connection between the upper and lower ends of the post insulator and the flange. The detection range is around the insulator. The content of ultrasonic inspection is creeping wave and longitudinal wave detection. |
