一种复合材料绝缘子的电老化试验方法
摘要：
本发明公开了一种复合材料绝缘子的电老化试验方法，包括以下步骤：S1、在交流500kV空心复合绝缘子产品中，任取1只产品作为试验品；S2、对试验品施加477kV(有效值)的工频电压，连续施加90天；S3、试验过程中，试验品不闪络、不击穿，无异常发热(用红外线测温仪，测试试验品各部位温度不大于65℃即可，每天测试一次)，则通过本试验。本发明提出一种复合材料绝缘子的电老化试验方法，以解决上述背景技术中提出现有技术中长寿命、高可靠性空心复合绝缘子产品1.5倍额定相电压下的90天电老化试验无法得到验证的问题。
摘要（英）：

The invention discloses a testing method for electrical aging of a composite material insulator. The method comprises the following steps: S1, taking one product from AC 500kV hollow composite insulator products as a tested product; S2, applying 477kV (effective value) of the power frequency voltage to the tested product for 90 days; S3, during the test, if the tested product does not flash, breakdown, and has no abnormal heating (using an infrared thermometer to test the temperatures of each part of the tested product not more than 65 DEG C, once a day), and then passes the test. The testingmethod for electrical aging of the composite material insulator solves a problem that the prior art provided in the above-mentioned background art cannot verify a 90-days electrical aging test of thelong-life and high-reliability hollow composite insulator product under a 1.5 times rated phase voltage.
