| 摘 要： | 经济、准确地检测绝缘子的方法对于保证输电线路的安全运行具有重要的意义。介绍了目前检测绝缘子几种常用检测方法,综合评价了电场测量法、泄漏电流法、超声波检测法、红外测温法等优缺点。随着对输电线路安全的日益重视,综合输电线路实时在线检测系统是绝缘子检测技术的主流发展趋势。现有在线检测系统能否普遍应用的主要障碍是线路杆塔的数量巨大。指出要实现真正意义上的绝缘子在线检测,应统一规范接口,严格制定免维护质量标准,选取合适的特征量,降低装置的复杂度,选择合理的信号远程传输方式。

| Abstract: | It is very important to have an economic and accurate method of insulator fault detecting for ensuring reliable service of transmission line.The common detection methods were presented.and evaluated such as electric stress measuring,leakage current testing,ultrasonic detecting and infrared-temperature measuring.Paying more attention to ensuring transmission line safety,the real time on-line detection trends to main development.The main obstacle which prevents the common usage of on-line detecting system is the large quantity of line poles and towers.For introducing on-line detection of insulators it is necessary to unify the interface,prepare a strict maintenance-free instruction,determine proper characteristics,simplify the installation and select a reasonable mode of long-diatance signal transmission. |
