Abstract

The volt-time characteristic of the suspension insulator equipped in power system is an important property. It is used for the determination of protective level against the overvoltage. But in practical all suspension insulators are used in string insulator. Therefore, it is essential to obtain the characteristic of string insulator. In this study the insulators in string are porcelain insulator ANSI class 52-1 and 52-2, respectively. Under the standard lightning impulse voltage, positive and negative, the volt-time characteristics are obtained by statistical method. The results show that the increase of breakdown voltage is not proportional to the number of insulators in the string. For the positive impulse voltage, breakdown time is increased with the number of insulators. But it does not vary much for positive impulse voltage breakdown time, about 1.0-3.6 μs. Moreover, the mathematical model used to predict the volt-time characteristic of string insulator is proposed and it found to be well with the tested results.

配电系统中悬挂串形绝缘子电压-时间特性的变化

电力系统中悬挂绝缘子的伏时特性是一项重要的性能。它用于测定对过电压的保护等级。但在实际应用中，所有悬浮绝缘子都用于串绝缘子。因此，了解串形绝缘子的特性是十分必要的。在本研究中，串中的绝缘子分别为ANSI等级52-1和52-2的瓷绝缘子。在标准雷击电压、正、负电压下，用统计方法得到了电压-时间特性。结果表明，击穿电压的增加与串内绝缘子数不成正比。对于正冲击电压，击穿时间随绝缘子数目的增加而增加。正冲击电压击穿时间变化不大，约为1.0 ~ 3.6 μs。此外，本文还建立了预测串形绝缘子电压-时间特性的数学模型，该模型与试验结果吻合较好。
