零值绝缘子带电检测方法探讨

Live detection method of the zero value insulators

通过多种零值绝缘子带电检测的模拟试验,对比了零值绝缘子检测的绝缘电阻法、火花间隙法、电压分布法、红外热成像法的优缺点,结果表明红外热成像法更适合不停电状态下零值绝缘子的大面积普测。

By the simulation test of the various zero value insulators detection,the advantages and disadvantages of the three methods were compared with insulation resistance method,spark gap method and infrared thermal imaging method.The results show that the infrared thermal imaging method is more adapted for the large area of the zero value insulator inspection with uninterrupted power.
