摘　　要：本文用三种不同聚酰亚胺漆,通过漆包工艺,制备了漆包扁线1#、线2#和线3#。分别制成U型试样和局部放电起始电压(PDIV)试样,做0.2%和0.5%的耐油水实验,然后测试外观、室温击穿电压和PDIV值,评价耐油水性能。结果发现:三个试样表现了不同的耐油水性能,漆包扁线1#可以耐0.2%和0.5%油水;线2#可以耐0.2%油水,不耐0.5%油水;线3#不耐0.2%和0.5%油水。本实验有效的区分了三种聚酰亚胺漆的耐油水性能,油中含水量增加,加剧聚酰亚胺绝缘层失效。This paper used three types of polyimide enamel to prepare enameled flat wire 1#,wire 2#,and wire 3#through the enameling process.Prepared U-shaped specimens and partial discharge initiation voltage(PDIV)specimens respectively,conducted 0.2%and 0.5%oilwater resistance experiments,then tested the appearance,room temperature breakdown voltage,and PDIV to evaluate the oil-water resistance performance.The results showed that the three wires exhibited different oil-water resistance.The enameled flat wire 1#was resistant to 0.2%and 0.5%oil-water;Wire 2#was resistant to 0.2%oil-water,but not 0.5%oil-water;Wire 3#was not resistant to 0.2%and 0.5%oil-water.This experiment effectively distinguished the oil-water resistance performance of three types of polyimide enamel.The increased water content in oil exacerbated the failure of polyimide insulation layer.
